Botanical Name: Verbascum thapsus
Family: Scrophulariaceae
Kingdom: Plantae
Order: Lamiales
Genus: Verbascum
Species: V. thapsus

Common NamesMullein
V. thapsus is known by a variety of names. European reference books call it “Great mullein”. In North America, “Common mullein” is used. In the 19th century it had well over 40 different common names in English alone. Some of the more whimsical ones included “Hig candlewick”, “Bullicks lungwort”, “Adams-rod”, “Feltwort“, “Hare’s-beard” and “Ice-leaf”. Vernacular names include innumerable references to the plant’s hairiness: “Woolly”, “Velvet” or “Blanket Mullein“,  “Beggar’s”, “Moses'”, “Poor Man’s”, “Our Lady’s” or “Old Man’s Blanket”, and so on (“Flannel” is another common generic name).

Some names refer to the plant’s size and shape: “Shepherd’s Club(s)” or “Staff”, “Aaron’s Rod” (a name it shares with a number of other plants with tall, yellow inflorescences), and a plethora of other “X’s Staff” and “X’s Rod”. The name “Velvet” or “Mullein Dock” is also recorded, where “dock” is a British name applied to any broad-leaved plant

Habitat:
Verbascum thapsus has a wide native range including Europe, northern Africa and Asia, from the Azores and Canary Islands east to western China, north to the British Isles, Scandinavia and Siberia, and south to the Himalayas. In northern Europe, it grows from sea level up to 1,850 m altitude,  while in China it grows at 1,400–3,200 m altitude.

It has been introduced throughout the temperate world, and is established as a weed in Australia, New Zealand, tropical Asia, La Réunion, North America, Hawaii, Chile, Hispaniola and Argentina. It has also been reported in Japan.

In the United States it was imported very early in the 18th. century and cultivated for its medicinal and piscicide property. By 1818, it had begun spreading so much that Amos Eaton thought it was a native plant. In 1839 it was already reported in Michigan and in 1876, in California. It is now found commonly in all the states. In Canada, it most common in Southern Quebec, Ontario and British Columbia, and in the Maritime Provinces, with scattered populations in between.

Great Mullein most frequently grows as a colonist of bare and disturbed soil, usually on sandy or chalky soils. It grows best in dry, sandy or gravelly soils, although it can grow in a variety of habitats, including banksides, meadows, roadsides, forest clearings and pastures. It germinates almost solely in bare soil, at temperatures between 10 °C and 40 °C. This ability to grow in a wide range of habitats has been linked to strong phenotype variation rather than adaptation capacities. While it can germinate in total darkness if proper conditions are present (tests give a 35% germination rate under ideal conditions), in the wild, it will only do so if the seeds are exposed, or very close to the soil surface. While it can also appear in areas where some vegetation exist, growth of the rosettes on bare soil is four to seven times more rapid.

Description:
Verbascum thapsus  is a hairy biennial plant that can grow to 2 m or more tall. Its small yellow flowers are densely grouped on a tall stem, which bolts from a large rosette of leaves. It grows in a wide variety of habitats, but prefers well-lit disturbed soils, where it can appear soon after the ground receives light, from long-lived seeds that persist in the soil seed bank. It is a common weedy plant that spreads by prolifically producing seeds, but rarely becomes aggressively invasive, since its seed require open ground to germinate. It is a very minor problem for most agricultural crops, since it is not a very competitive species, being intolerant of shade from other plants and unable to survive tilling. It also hosts many insects, some of which can be harmful to other plants. Although individuals are easy to remove by hand, populations are difficult to eliminate permanently.

Verbascum thapsus is a dicotyledonous biennial that produces a rosette of leaves in its first year of growth. The leaves are large, up to 50 cm long, and are covered with woolly, silvery hairs. The second year plants normally produce a single unbranched stem 1–2 m tall, with some plants reportedly having stems reaching up to 3.5 m tall. In the East of its range in China, it is, however, only reported to grow up to 1.5 m tall. The tall pole-like stems end in a dense spike of flowers, that can occupy up to half the stem length. All parts of the plants are covered with star-shaped trichomes. Its chromosome number is 2n = 36.

On flowering plants the leaves are alternately arranged up the stem. The leaves are thick, and decurrent on the stem, with much variation especially between the upper and lower leaves on the stem, with leaf shape ranging from between oblong to oblanceolate, ranging in size up to 50 cm long and 14 cm across (19 inches long and 5 inches wide).They become smaller higher up the stem, and less strongly decurrent lower down the stem. The flowering stem is solid and 2–2.5 cm (nearly an inch) across, and occasionally branched just below the inflorescence, usually when damaged. After flowering and seed release the stem and fruits usually persist in winter[10] after drying into hard, stiff structures topped with densely packed, ovoid shaped, dry seed capsules. The dried stems are most often dark brownish, and often persist standing until the next spring or even into the next summer. The plants produce a shallow taproot.

The flowers are pentamerous with five stamen that are fused to the petals, a 5-lobed calyx tube and a 5-petalled corolla, the latter bright yellow and an 1.5–3 cm (0.5–1 inch) wide. The flowers are almost sessile, with very short pedicels (2 mm, 0.08 in). The five stamens are of two types, with the three upper stamens being shorter, with filaments covered by yellow or whitish hairs, and having smaller anthers, while the lower two stamens have glabrous filaments and larger anthers. The plant produces small ovoid (6 mm, 0.24 in) capsules that split open by way of two valves, each capsule containing large numbers of minute brown seeds less than a millimetre (0.04 in) in size, with longitudinal ridges. A white-flowered form V. thapsus f. candicans occurs. Flowering lasts for up to three months from early to late summer (June to August in northern Europe), with flowering starting at the bottom of the spike and progressing irregularly up the spike; each flower opens for part of a day and only a few open at the same time around the stem.

Edible Uses:  
Tea: An aromatic tea can be made by boiling 1 tbs. dried leaves or root, in 1 cup water for 5 – 10 min. A sweeter tea can be made by infusing the fresh or dried flowers. Or for children and the elderly use milk instead of water. Sweeten if desired.

Main  Uses: 
Great Mullein has been used since ancient times as a remedy for skin, throat and breathing ailments. It has long had a medicinal reputation, especially as an astringent and emollient. It contains mucilage, several saponins, coumarin and glycosides. Dioscorides recommended it for diseases of the lung and it is nowadays widely available in health and herbal stores.

Medical uses

Great Mullein has been used as an alternative medicine for centuries, and in many countries throughout the world, the value of Great Mullein as a proven medicinal herb is now backed by scientific evidence. Some valuable constituents contained in Mullein are Coumarin and Hesperidin, they exhibit many healing abilities. Research indicates some of the uses as analgesic, antihistaminic, anti-inflammatory, anticancer, antioxidant, antiviral, bacteristat, cardio-depressant, estrogenic, fungicide, hypnotic, sedative and pesticide are valid.
Dioscorides first recommended the plant 2000 years ago, against pulmonary diseases, and this has remained one of its primary uses, especially against cough. Leaf decoctions or herbal teas were used for expectoration, consumption, dry cough, bronchitis, sore throat and hemorrhoids. Leaves were also smoked against pulmonary ailments, a tradition that in America was rapidly transmitted to Native American peoples. They used the non-indigenous plant to make syrups against croup. The combination of expectorant saponins and emollient mucilage makes the plant particularly effective for cough. All preparations meant to be drunk have to be finely filtered to eliminate the irritating hairs.

Oil from the flowers was used against catarrhs, colics and, in Germany, earaches, frostbite, eczema and other external conditions. Topical application of various V. thapsus-based preparations was recommended for the treatment of warts, boils, carbuncles, hemorrhoids, and chilblains, amongst others. Recent studies have found that Great Mullein contains glycyrrhizin compounds with bactericide and potential anti-tumoral action. These compounds are concentrated in the flowers. Different extracts have varying levels of efficiency against bacteria. In Germany, a governmental commission sanctioned medicinal use of the plant for catarrhs. It was also part of the National Formulary in the United States[66] and United Kingdom. The plant’s leaves, in addition to the seeds, have been reported to contain rotenone, although quantities are unknown.

In Spanish, Great Mullein is called Gordolobo. Gnaphalium conoideum was used in a fashion similar to Mullein by the Mexican Aztecs, which caused confusion in naming, and both are sold under the name “Gordolobo”, (although V. thapsus is not found in Mexico). This situation has led to at least one case of poisoning due to confusion of G. conoideum with Senecio longilobus.

It is widely used for herbal remedies with emollient and astringent properties. It is especially recommended for coughs and related problems, but also used in topical applications against a variety of skin problems. It was traditionally smoked for lung conditions.  It is also a diuretic used to relieve urinary tract inflammation, diarrhea, and inflammation, colitis, or other bleeding in the bowel.  The flowers extracted into olive oil make a preparation that is known to reduce the pain and inflammation of earache, insect bites, bruises, hemorrhoids, and sore joints.  A distilled flower water or a poultice has been placed on burns, ringworm, boils and sores.  The leaves are used in homeopathic products for migraine and earache.

Medicinally, it is expectorant, anti-inflammatory, antibiotic, astringent, and demulcent (which means soothing). Mullein tea is primarily used as an effective treatment for coughs and lung disorders. Due to its mucilage content, Mullein is also a soothing emollient for inflammatory skin conditions and burns.


Other uses

Dye, Insecticide, Insulation, Lighting, Tinder, Wick. A yellow dye is made from the flowers by boiling them in water. When used with dilute sulphuric acid they produce a rather permanent green dye, this becomes brown with the addition of alkalis. An infusion of the flowers is sometimes used to dye the hair a golden color. The leaves contain rotenone, which is used as an insecticide. The dried leaves are highly flammable and can be used to ignite a fire quickly , or as wick for candles.
Like many ancient medicinal plants (Pliny the Elder describes it in his Naturalis Historia), Great Mullein was linked to witches, although the relationship remained generally ambiguous, and the plant was also widely held to ward off curses and evil spirits.The seeds contain several compounds (saponins, glycosides, coumarin, rotenone) that cause breathing problems in fish, and have been widely used as piscicide for fishing.

The plant was also used to make dyes and torches.  The flowers provide dyes of bright yellow or green, and have been used for hair dye.The dried leaves and hair were made into candle wicks, or put into shoes to help with insulating them. The dried stems were also dipped into suet or wax to make torches. Due to its weedy capacities, the plant, unlike other species of the genus (such as V. phoeniceum), is not often cultivated.

Folklore
An old superstition existed that witches used lamps and candles provided with wicks of Mullein in their incantations, and another of the plant’s many names, ‘Hag’s Taper’, refers to this. Both in Europe and Asia the power of driving away evil spirits was ascribed to the Mullein. Being a sure safeguard against evil spirits and magic, and from the ancient classics, it was this plant which Ulysses took to protect himself against the wiles of Circe. 

Mullein oil: Use flowers or root. Place in blender or crush, fill jar, cover with olive oil, set in warm place for 2 weeks. Strain before use.

American False-Hellebore (Veratrum viride Ait)

 

Veratrum veride
Image via Wikipedia

Botanical Name:Veratrum viride Ait
Family: Melanthiaceae
Kingdom: Plantae
Order: Liliales
Genus: Veratrum
Species: V. viride
Other common names.—True veratrum, green veratrum American veratrum green hellebore, swamp hellebore, big hellebore, false hellebore, bear corn, bugbane, bugwort, devil’s-bite, earth gall, Indian poke, itchweed, tickleweed, duck-retter.
Indian Poke, Indian Hellebore, False Hellebore, Green False Hellebore)
Part used.—The rootstock, dug in autumn when the leaves have died down.

Habitat and range.—American false-hellebore is native in rich wet woods, swamps and wet meadows, its range extending from Canada, Alaska, and Minnesota south to Georgia and Tennessee.

In eastern North America, var. viride occurs from southwestern Labrador and southern Quebec south to northern Georgia. In the west, var. eschscholzianum occurs from Alaska and Northwest Territory south through Yukon, British Columbia, Alberta, Washington, Idaho, Montana, and Oregon to northern California.

It is found in wet soils in meadows, sunny streambanks, and open forests, from sea level in the north of the range, up to 1,600 m in the southeast and 2,500 m in the southwest

Description.—The large bright-green leaves of this plant make their way through the ground early in spring, followed later in the season by a stout, erect leafy stem, sometimes growing as tall as 6 feet. It is round and solid, pale green, closely surrounded by the sheathing bases of the leaves and unbranched except in the flowering head. The large leaves, the lower ones of which are from 6 to 12 inches in length and 3 to 6 inches in width, are hairy and pleated like a fan. The numerous greenish-yellow flowers are produced from May to July in rather open clusters. The plant is very poisonous……...CLICK & SEE THE PICTURES

It is extremely toxic, and is considered a pest plant by farmers with livestock. The species has acquired a large number of common names within its native range, including American False Hellebore, American White Hellebore, Bear Corn, Big Hellebore, Corn Lily, Devils Bite, Duck Retten, Indian Hellebore, Itch-weed, Itchweed, Poor Annie, Blue Hellebore, and Tickleweed.

It is a herbaceous perennial plant reaching 0.7–2 m tall, with a solid green stem. The leaves are spirally arranged, 10–35 cm long and 5–20 cm broad, elliptic to broad lanceolate ending in a short point, heavily ribbed and hairy on the underside. The flowers are numerous, produced in a large branched inflorescence 30–70 cm tall; each flower is 5–12 mm long, with six green to yellow-green tepals. The fruit is a capsule 1.5–3 cm long, which splits into three sections at maturity to release the numerous flat 8–10 mm diameter seeds. The plant reproduces through rhizome growth as well as seeds.

There are two varieties:
Veratrum viride var. viride. Eastern North America. Side branches of inflorescence erect or spreading.
Veratrum viride var. eschscholzianum (Roemer & Schultes) Breitung. Western North America. Side branches of inflorescence drooping.

The related western North American Veratrum californicum (White False Hellebore, Corn Lily) can be distinguished from sympatric var. eschscholzianum by its whiter flowers, with erect side branches of the inflorescence

Medicinal uses:
The plant is highly toxic, causing nausea and vomiting. If the poison is not evacuated, cold sweat and vertigo appears. Respiration slows, cardiac rhythm and blood pressure falls, eventually leading to death.

It is used externally by several Native American nations. Although is rarely ever used in modern herbalism due to its concentration of various alkaloids, it has been used in the past against high blood pressure and rapid heartbeat; a standardized extract of V. viride alkaloids known as alkavervir was used in the 1950s and 1960s as an antihypertensive.  The root contains even higher concentrations than the aerial parts.

Any use of this plant, especially internal use, should be carried out with great care and preferably only under the supervision of a qualified practitioner.  A decoction of the root has been used in the treatment of venereal disease. The roots have been grated then chewed and the juice swallowed as a treatment for colds. A poultice of the mashed raw root has been used as a treatment for rheumatism, boils, sores, cuts, swellings and burns. The dried and ground up root has been used as a dressing on bruises and sores. A poultice of the chewed root has been applied to rattlesnake bites to draw out the poison. The powdered root has been rubbed on the face to allay the pain of toothache.  A decoction of the root has been taken orally by both men and women as a contraceptive. A dose of one teaspoon of this decoction three times a day for three weeks is said to ensure permanent sterility in women.

The plant was used by some tribes to elect a new leader. All the candidates would eat the root, and the last to start vomiting would become the new leader.

A vaccine in the making — equally effective for birds, men and other mammals — offers a shield against another outbreak of bird flu.

……………...CLICK & SEE

Of all the viruses that can cause a devastating pandemic (worldwide outbreak), the influenza virus is the most likely to cause one. Influenza is a tricky disease to control. The world has already seen several outbreaks, of which the influenza pandemic in 1918 was the most serious: at least 20 million people died all over the world then. There were pandemics in 1957, 1968 and 1977, but of much less severity.

Recently, avian influenza (or bird flu) has emerged as a candidate that can cause a serious pandemic. Experts warn that another outbreak is imminent and we have only limited ability to control it if one breaks out. However, several vaccines — now in the laboratory stage — offer hope.

One of the problems of bird flu is that it affects birds as well as humans and other mammals. The virus may be slightly different in each of the animals, and it is difficult to give different vaccines for different animals during a pandemic. At the Department of Veterinary Medicine in the University of Maryland in the US, Daniel Perez and his colleagues have developed a vaccine that can control the disease in birds, humans and rodents. It is based on a region of the virus gene that is common to all the strains. “We have shown that the vaccine works in rodents and does not cause the disease,” says Perez.

This vaccine has been tested in rats but not yet in humans. Meanwhile, at the University of Pittsburgh medical college, scientists are testing a vaccine against the deadliest of all avian flu viruses, the H5N1. This is a genetically engineered vaccine that takes only 10 weeks to manufacture. The other vaccines now in the market are made using chicken eggs, and take several months to manufacture, apart from not being able to provide enough immunity. Two months ago, the institution received a $3.6 million grant to test the vaccine in non-human primates.

Currently, three companies manufacture vaccines against the avian flu virus H5N1, all of them approved in different countries in the last year and a half. Sanofi Pasteur’s vaccine was approved in the US in 2007, GlaxoSmithkline’s vaccine was approved in Europe in May this year. Australia approved a vaccine from CSL Limited. All of them are live attenuated virus — which have been so altered that they can’t cause disease — raised on chicken eggs. While all of them provide some protection, none of them can prevent a pandemic. This is because the virus mutates fast, and we do not know what strain of the virus would be involved in a pandemic.

One of the known — and fortunate — facts about the bird flu virus is its specificity. The virus that infects birds does not easily infect humans. This is why many outbreaks in birds have not resulted in human infections. Which is probably also why human to human transmission has not happened in large numbers so far.

However, such a transmission is not scientifically impossible. Since the virus mutates fast, strains of broader range can emerge. They can infect humans, pigs, rats, birds and other animals. It would be difficult, if not impossible, for us to make different vaccines for different animals. The Maryland University team has shown that it is possible to make a single vaccine effective in many animal species.

This vaccine is based on a DNA backbone that is common to all the strains. This backbone lies inside the virus and not outside. The scientists have a strain of the virus called WF10 with this backbone. They have isolated other influenza viruses that are related to this strain, including the human influenza virus. They had earlier shown that by tweaking the gene of this strain they could make a vaccine effective in birds. Now they have shown that, by further modification, this strain can protect many species against the influenza infection. In particular, they have shown that it provides protection in rats against H5N1, the most lethal strain against which human vaccines are made. Says Perez: “We have done animal trials, but we are yet to do human trials.”

There are other developments that could help in preventing a major pandemic. A series of DNA vaccines against H5N1 are also under development in several institutions. They are the Virology Research Institute in Maryland, which began clinical trials last year, the University of Pennsylvania School of Medicine, and the Rockefeller University. A DNA vaccine is a piece of DNA that can directly make the protein that produces an immune response. It is safe, because it cannot by itself cause the disease. The vaccines can be made rapidly, which is invaluable in case of an epidemic.

However, there are technical issues, which all these teams claim to have solved. If they work, we could soon have a vaccine that can be rapidly made when there is an epidemic. Let us wait and watch their progress.

Oregon-grape (Mahonia aquifolium, Berberidaceae)

Mahonia nervosaImage via Wikip

Botanical Name:Mahonia aquifolium

Kingdom: Plantae

Division: Magnoliophyta

Class: Magnoliopsida

Order: Ranunculales

Family: Berberidaceae

Genus: Mahonia

Species: M. aquifolium

Alternative Names: Alegrita, California Barberry, Japonica, Mahonia, Mountain Grape, Mountain Holly, Pepperidge, Sourberry, Sowberry and Yellow Root.

Habitat:Oregon-grape is a native plant on the North American west coast from British Columbia to northern California, occurring in the understory of Douglas-fir forests and in brushlands. It is the state flower of Oregon.

Description:Oregon-grape (Mahonia aquifolium, Berberidaceae) is an evergreen shrub related to the barberry. Some authors place Mahonia in the barberry genus, Berberis. The Oregon-grape is not closely related to grapes, but gets its name from the purple clusters of berries whose color and slightly dusted appearance is reminiscent of grapes. It is sometimes called Tall Oregon-grape to distinguish it from Creeping Oregon-grape (M. repens) and “Cascade” or Dwarf Oregon-grape (M. nervosa). The name is often left un-hyphenated as Oregon grape, though doing so invites confusion with the true grapes. It also occasionally appears in print as Oregongrape.
.

click to see the pictures.

Oregon-grape grows to 1-5 m tall. Its leathery leaves resemble holly and the stems and twigs have a thickened, corky appearance. The flowers, borne in late spring, are an attractive yellow.

Different Uses:Oregon-grape is used in landscaping similarly to barberry, as a plant suited for low-maintenance plantings and loose hedges. Oregon-grape is resistant to summer drought, tolerates poor soils, and does not create excessive leaf litter. Its berries attract birds.

The small purplish-black fruits, which are quite tart and contain large seeds, are sometimes used locally mixed with Salal to make jelly. The fruit is bitter, and generally not eaten without being sweetened first. As the leaves of Oregon-grape are holly-like and resist wilting, the foliage is sometimes used by florists for greenery and a small gathering industry has been established in the Pacific Northwest. The inner bark of the larger stems and roots of Oregon-grape yield a yellow dye.In some areas outside its native range, Oregon-grape has been classified as an invasive exotic species that may displace native vegetation.

Ingredients:The root of Oregon grape contains berberine alkaloids such as berberine and hydrastine. Berberine is one of the active ingredients found in goldenseal that helps bloodshot eyes and sore throats.Oregon grape rhizome and roots have the following properties: alterative, antibiotic, antiseptic, astringent, bitter taste, cholagogue, cooling, diuretic, emetic, laxative, thyroid stimulant. They affect the blood, intestines, liver, skin, spleen and stomach.

Medicinal Use:
The plant is used medicinally by herbalists. Recent studies indicate that M. aquifolium contains a specific multidrug resistance pump inhibitor (MDR Inhibitor) named 5’methoxyhydnocarpin (5’MHC) which works to decrease bacterial resistance to antibiotics and antibacterial agents.

Oregon grape root is commonly used medicinally as an effective alternative to the threatened goldenseal. Both plants similarly contain the alkaloid berberine, known as an anti-inflammatory and anti-bacterial used in the treatment of infection. Berberine and other alkaloids present in Oregon grape root have been shown to kill a wide range of microbes and have been effective in speeding recovery from giardia, candida, viral diarrhea, and cholera. Mahonia aquifolium is also known to be capable of treatment on inflammatory skin diseases such as Eczema and Psoriasis. Oregon grape root also has anticancer properties that are receiving more attention by researchers.[citation needed] Other actions may include alterative, diuretic, laxative and tonic.

Oregon Grape Root is used as a treatment for skin diseases and as a treatment for prostate infection. It is also used as a blood cleanser, to stimulate the liver and gall bladder, and as a mild laxative. Externally, a decoction of the root bark is used as a liniment for arthritis. Do not use during pregnancy.


Oregon Grape Root is a disinfectant and helps relieve pain during urinary infections. It acts as an antispasmodic and relieves pain from kidney stones and helps clear urine with thick mucus or red sediments. Barberry is also useful for many liver and gall bladder problems, hepatitis, and cirrhosis. It assists in detoxification from effects of poor diet, medications or drugs and helps stimulate the immune system.

Health Warning: Because of a potential toxicity or adverse effects of berberine, consult a reputable herbalist regarding dosages and treatments. Use of berberine is not recommended during pregnancy or breastfeeding.


Traditional uses of Oregon grape include
: acne, arthritis, bronchial congestion, chronic fatigue, eczema, hepatitis, herpes, hypoglycemia, indigestion, lymphatic congestion, menstrual problems, psoriasis, scrofula, syphilis, and vaginitis.

Oregon Grape is rich in vitamin C and has been made into a beverage that was useful for scurvy, fever and upset stomachs. This drink was also used as a mouthwash and gargle. The root soaked in warm beer was said be helpful for cases of hemorrhaging and jaundice.

In modern times, Oregon grape is known as a good liver cleanser. This is due to the fact that it increases bile production. This action also aids digestion and purifies the blood. When combined with dandelion, milk thistle or celandine, it can be very effective in combatting hepatitis B and jaundice.

Oregon grape’s antiseptic properties
make it a useful external application for skin conditions. Internally, its blood purifying properties make it useful for blood conditions as well as skin problems.

Recent studies have shown that berberine containing herbs may be useful for those suffering from diarrhea and especially bacterial dysentery. This high berberine content makes it a good alternative to goldenseal in many cases, including infections.

Doses:Fresh Oregon grape root and rhizome should be used promptly to assure the strongest potency. A decoction is made by steeping 1 teaspoon of the root for 30 minutes in 1-1/2 pints of boiling water. This mixture is then strained before drinking. In capsule form, take 1-2 capsules 2-3 times daily. In liquid form, take 1/4 to 1/2 teaspoon daily of Oregon grape.

Genus: Rhamnus
Subgenus: Frangula

Synonyms : Cervispina cathartica (L.) Moench,  Frangula purshiana, Rhamnus purshianus

Common Name: Cascara Buckthorn, Cascara, Bearberry, and in the Chinook Jargon, Chittam or Chitticum; Common Buckthorn

Habitat: Cascara sagrada is native to  Europe, including Britain, from Scandanavia south and east to N. Africa and W. Asia.  It grows in fen peat, scrub, hedges, ash and oak woods, on calcareous often dry soils.
Parts Used:Dried aged bark

Description:

Cascara sagrada is a small deciduous tree that grows from 15-20 feet in height. It has pubescent stems covered with reddish-brown bark and often gray lichen. The tree bears dark green elliptic to oblong-ovate leaves with prominent veins and toothed margins. The leaves are rounded at the base and have somewhat hairy undersides. Short-stemmed clusters of small, greenish-white flowers grow from the upper leaf axils; they eventually produce black, pea-sized drupes that are poisonous.

CLICK & SEE THE PICTURES

The bark is brownish to silver-grey with light splotching. The leaves are deciduous, alternate, clustered near the ends of twigs; they are oval, 5–15 cm long and 2–5 cm broad with a 0.6–2 cm petiole, dark shiny green on top, fuzzy and paler green below. The flowers are tiny, 4–5 mm diameter, with five greenish yellow petals; the flowering season is brief, disappearing by early summer. The fruit is a berry 6–10 mm diameter, bright red at first, quickly maturing deep purple or black, and containing three seeds.

It grows in moist, acidic soils in the shady side of clearings or in the marginal forest understory, near the edges of mixed deciduous-coniferous forests. It typically grows as a second-generation tree after alders have colonized a barren plot of land.

Cultivation:
Succeeds in any reasonably good soil. Prefers a dry or moist calcareous soil in sun or light dappled shade. This species is hardy to at least -15°c. Plants regenerate well after cutting or burning but young plants are rather prone to frost damage when grown in an exposed position. Plants are resistant to cattle grazing but young plants can be damaged by rabbits. Plants have a very shallow root system. This species often bears the aecidospore stage of ‘crown rust’ of oats so it should not be grown near cereals. The species in this genus are notably resistant to honey fungus. A good bee plant and a main food plant for the brimstone butterfly. Dioecious. Male and female plants must be grown if seed is required.

Propagation :
Seed – best sown as soon as it is ripe in the autumn in a cold frame. Stored seed will require 1 – 2 months stratification at 5°c and should be sown as early in the year as possible in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle, and grow them on in the greenhouse or cold frame for their first winter. Plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, July/August in a frame. Cuttings of mature wood of the current year’s growth, autumn in a frame. Layering in early spring.

Medicinal Uses:Constipation, Colon Disorders, Liver Problems, Poor Digestion, Colitis, Hemorrhoids, Skin Problems.
The dried, aged bark of this tree has been used continually for at least 1,000 years by both native and immigrant Americans as a laxative natural medicine, commercially called “Cascara Sagrada“, but old timers call it “chitticum bark”.

Cascara is a very effective laxative, containing hydroxymethyl anthraquinones that cause peristalsis of the large intestine, emodin and other rhamnoid glycosides. It has been used as such by many First Nations groups. For example, Cascara bark tea was drunk as a laxative by Nuxalk, Coast Salish, Nuu-chah-hulth, and Kwakwakawakw, and a decoction of the inner bark and water was used as a remedy for dysentery. The bark is often aged before use so it will be less likely to cause nausea. First introduced to Europe in 1877, about 3 million pounds of the bark is harvested annually for use in commercial laxatives.  Squaxin used a Cascara infusion to wash sores–sometimes people chewed the bark and then spit it on sores. The bark has also been used to treat heart strain, internal strains, and biliousness. Skagit people burn the bark and mix the charcoal with grease to rub on swellings, and also have employed the bark in a green dye for mountain goat wool. Makah eat the fresh berries in July and August. Internally used for chronic constipation, colitis, digestive complaints, hemorrhoids, liver problems, and jaundice.  It is a medium-strength laxative and somewhat weaker than Rhubarb root and Senna leaf.   Externally used to deter nail biting.

Cascara Sagrada means “sacred bark” in Spanish. The much more pertinent name chitticum means “shit come” in Chinook Jargon; chittam comes from the Chinook Jargon phrase chittam stick = “laxative tree” which is similarly from the English word “shit”.

The bark is harvested mostly from wild trees; over-harvesting in the middle 1900s eliminated mature trees near many settled areas. Once stripped from the tree, the bark is aged for about 1 year to make its effect milder. Fresh cut, dried bark causes vomiting and violent diarrhea.

Short term side effects of Cascara Sagrada herb:
A medline search did not reveal any significant short term cascara sagrada side effects as long as it is not used for more than a week or two at a time without a break. It is best to avoid cascara sagrada if you have a chronic intestinal condition such as ulcerative colitis, or diverticular disease.

Long term cascara sagrada side effects:
When cascara sagrada or other anthraquinone containing plants are used for prolonged periods, potentially serious side effects can occur. These cascara sagrada side effects may include cramping in the abdomen and loss of body fluids. Dark pigmentation in the colon can occur and this is called melanosis coli.

Cascara Sagrada Research Update:
Colon cleansing regimens. A clinical study in 1200 patients.
Gastrointest Radiol. 1982;7(4):383-9
The purgative effect of bisacodyl, anthraquinone glycosides ( Cascara sagrada ), and sodium picosulfate, alone or in combination with a saline purge and a tap water enema, was studied in 1200 patients. The cleansing effect was scored with regard to retained fecal residue evident on double-contrast studies of the colon. The combination of a contact laxative and a saline purge produced good cleansing effect in 52%-80% of the patients. With an additional tap water enema given 1 hour before the colon examination, however, 96% of the colons were clean. The taste and the effects of the cleansing systems were tolerated favorably by more than 90% of the patients. However, 17% reported restriction in work capacity on the day of bowel cleansing.

Other Uses:
Dye; Hedge; Hedge; Wood.

A green dye is obtained from the immature fruit. Mixed with gum arabic and limewater, it makes a green pigment used in watercolour painting. Yellow, orange and brownish dyes can also be obtained. The colours are rich but fugitive. A yellow dye is obtained from the bark. It has been used to colour paper and maps. Often grown as an informal hedge, it is also amenable to trimming. Wood – hard, handsome with a marble-like grain. Used for small turnery.

Known Hazards: The fruit is purgative but not seriously poisonous. Other parts of the plant may also be poisonous. Adverse effects: Diarrhoea, weakness. Urine may turn dark yellow or red which is harmless. Possible body potassium loss if used for more than 10 consecutive days
