Chamomile

Botanical Name: Matricaria chamomilla
Family: Asteraceae
Tribe: Anthemideae
Genus: Matricaria
Species: M. chamomilla
Kingdom: Plantae
Order: Asterales

Synonym: Matricaria recutita

Common Names:Chamomile, German chamomile, Hungarian chamomile (kamilla), wild chamomile or scented mayweed,

Habitat:Chamomile is native to southern and eastern Europe. It is also grown in Germany, Hungary, France, Russia, Yugoslavia, and Brazil. It was introduced to India during the Mughal period, now it is grown in Punjab, Uttar Pradesh, Maharashtra, and Jammu and Kashmir. The plants can be found in North Africa, Asia, North and South America, Australia, and New Zealand. Hungary is the main producer of the plant biomass. In Hungary, it also grows abundantly in poor soils and it is a source of income to poor inhabitants of these areas. Flowers are exported to Germany in bulk for distillation of the oil. It often grows near roads, around landfills, and in cultivated fields as a weed, because the seeds require open soil to survive.

Description:
Chamomile is an annual plant with thin spindle-shaped roots only penetrating flatly into the soil. The branched stem is erect, heavily ramified, and grows to a height of 10–80 cm. The long and narrow leaves are bi- to tripinnate. The flower heads are placed separately, they have a diameter of 10–30 mm, and they are pedunculate and heterogamous. The golden yellow tubular florets with 5 teeth are 1.5–2.5 mm long, ending always in a glandulous tube. The flowers bloom in early to midsummer, and have a strong, aromatic smell. The flowers are 6–11 mm long, 3.5 mm wide, and arranged concentrically. The receptacle is 6–8 mm wide, flat in the beginning and conical, cone-shaped later, hollow—the latter being a very important distinctive characteristic of Matricaria—and without paleae. The fruit is a yellowish brown achene.

Cultivation:
German chamomile can be grown on any type of soil, but growing the crop on rich, heavy, and damp soils should be avoided. It can also withstand cold weather with temperature ranging from 2°C to 20°C. The crop has been grown very successfully on the poor soils (loamy sand) at the farm of the Regional Research Laboratory, Jammu. At Banthra farm of the National Botanical Research Institute, Lucknow, the crop has been grown successfully on soil with a pH of 9. Soils with pH 9–9.2 are reported to support its growth. In Hungary, it grows extensively on clayey lime soils, which are barren lands and considered to be too poor for any other crop. Temperature and light conditions (sunshine hours) have greater effect on essential oils and azulene content, than soil type. Chamomile possesses a high degree of tolerance to soil alkalinity. The plants accumulate fairly large quantity of sodium (66 mg/100 gm of dry material), which helps in reducing the salt concentration in the top soil.[43] No substantial differences were found in the characteristics of the plants grown 1500 km apart (Hungary–Finland). Under cooler conditions in Finland, the quantity of the oxide type in the essential oil was lower than in Hungary.

Propagation:
The plant is propagated by seeds. The seeds of the crop are very minute in size; a thousand seeds weigh 0.088–0.153 gm. About 0.3–0.5 kg of clean seed with a high germination percentage sown in an area of 200–250 m2 gives enough seedlings for stocking a hectare of land. The crop can be grown by two methods i.e. direct sowing of the seed and transplanting. Moisture conditions in the field for direct sowing of seeds must be very good otherwise a patchy and poor germination is obtained. As direct sowing of seeds usually results in poor germination, the transplanting method is generally followed. The mortality of the seedlings is almost negligible in transplanting.

Medicinal Uses:
Chamomile is used in herbal medicine for a sore stomach, irritable bowel syndrome, and as a gentle sleep aid. It is also used as a mild laxative and is anti-inflammatory and bactericidal. It can be taken as an herbal tea, two teaspoons of dried flower per cup of tea, which should be steeped for 10 to 15 minutes while covered to avoid evaporation of the volatile oils. The marc should be pressed because of the formation of a new active principle inside the cells, which can then be released by rupturing the cell walls, though this substance only forms very close to boiling point. For a sore stomach, some recommend taking a cup every morning without food for two to three months. It has been studied as a mouthwash against oral mucositis ]and may have acaricidal properties against certain mites, such as Psoroptes cuniculi.

One of the active ingredients of its essential oil is the terpene bisabolol. Other active ingredients include farnesene, chamazulene, flavonoids (including apigenin, quercetin, patuletin and luteolin) and coumarin.

Dried chamomile has a reputation (among herbalists) for being incorrectly prepared because it is dried at a temperature above the boiling point of the volatile components of the plant.

Chamomile is used topically in skin and mucous membrane inflammations and skin diseases. It can be inhaled for respiratory tract inflammations or irritations; used in baths as irrigation for anogenital inflammation; and used internally for GI spasms and inflammatory diseases. However, clinical trials supporting any use of chamomile are limited.

Possible Side Effects:
Chamomile, a relative of ragweed, can cause allergy symptoms and can cross-react with ragweed pollen in individuals with ragweed allergies. It also contains coumarin, so care should be taken to avoid potential drug interactions, e.g. with blood thinners.

While extremely rare, very large doses of chamomile may cause nausea and vomiting. Even more rarely, rashes may occur. A type-IV allergic reaction with severe anaphylaxis has been reported in a 38-year old man who drank chamomile tea.

Ferula galbaniflua

Botanical Name : Ferula galbaniflua
Family: Apiaceae
Genus: Ferula
Kingdom: Plantae
Order: Apiales

Synonyms: Ferula  galbaniflua. Bioss.&Buhse.

Common Name : Galbanum

Habitat:Ferula galbaniflua is native to the Mediterranean region east to central Asia, W. Asia – Central Iran, Turkey and southern Russia. mostly growing in arid climates. Herbaceous slopes in steppes.

Description:
Ferula galbaniflua is a  herbaceous perennial flowering plant growing to 1–4 m tall, with stout, hollow, somewhat succulent stems. The leaves are tripinnate or even more finely divided, with a stout basal sheath clasping the stem.They are grayish-tomentose, the radical ones being triangular in outline, and decompound-pinnate, pinnatifid, the sections being linear-obtuse. The radical leaves are large and the stem leaves small. The flowers are yellow, produced in large umbels. The umbels of flowers are few, the seeds shiny. The fruit is thin and flat, winged near the face, has slender, prominent ribs, and in the grooves presents single oil-tubes. Sometimes two narrow tubes are present. The commissure has no tubes.

The whole plant abounds with a milky juice, which oozes from the joints of old plants, and exudes and hardens from the base of the stem after it has been cut down, then is finally obtained by incisions made in the root. The juice from the root soon hardens and forms the tears of the Galbanum of Commerce. The best tears are palish externally and about the size of a hazel nut and when broken open are composed of clear white tears. The taste is unpleasant, bitterish, acrid, with a strong, peculiar, somewhat aromatic smell. The common kind is an agglutinated mass, showing reddish and white tears, this is of the consistency of firm wax, and can easily be torn to pieces and softened by heat; when cold it is brittle, and mixed with seeds and leaves, when imported in lumps it is often considered preferable to the tears as it contains more volatile oil. Distilled with water it yields a quantity of essential oil, about 6 drachms, to 1 lb. of gum. It was well known to the ancients and Pliny called it ‘bubonion.’ Galbanum under dry distillation yields a thick oil of a bluish colour, which after purification becomes the blue colour of the oil obtained from the flowers of Matricaria Chamomilla.

Cultivation:
Succeeds in most soils. Requires a deep fertile soil in a sunny position. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. Another report says that it tolerates temperatures down to at least -15°c and should therefore succeed outdoors in most parts of the country. Plants are intolerant of root disturbance due to their long taproot[200]. They should be planted into their final positions as soon as possible. The flowers have an unpleasant smell.
Propagation:
Seed – best sown as soon as the seed is ripe in a greenhouse in autumn. Otherwise sow in April in a greenhouse. Prick out the seedlings into individual pots as soon as they are large enough to handle. Plant them out into their permanent positions whilst still small because the plants dislike root disturbance. Give the plants a protective mulch for at least their first winter outdoors. Division in autumn. This may be inadvisable due to the plants dislike of root disturbance.

Edible Uses: Condiment.

The gum resin obtained from the root is used as a celery-like food flavouring.

Medicinal Uses:
Part Used-:Gum resin.
Constituents: Gum resin, mineral constituents, volatile oil, umbelliferine, galbaresino-tannol.

It is stimulant, expectorant in chronic bronchitis. Antispasmodic and considered an intermediate between ammoniac and asafoetida for relieving the air passages, in pill form it is specially good, in some forms of hysteria, and used externally as a plaster for inflammatory swellings.The leaf aqueous-ethanol extract of Feruia foetida has shown antioxidant and antihemolytic activities.

The whole plant, but especially the root, contains the gum resin ‘galbanum’. This is antispasmodic, carminative, expectorant and stimulant. It is used internally in the treatment of chronic bronchitis, asthma and other chest complaints. It is a digestive stimulant and antispasmodic, reducing flatulence, griping pains and colic. Externally it is used as a plaster for inflammatory swellings, ulcers, boils, wounds and skin complaints.

Other Uses:
The aromatic gum resin ‘Galbanum’ is obtained from wounds made in the stem. It is collected by removing soil from around the top of the root and then cutting a slice off the root and can also be obtained from incisions made in the stem. It is used medicinally and is also an ingredient of incense. It was an important ingredient of the incense used by the Israelites.

Matricaria inodora

Botanical Name : Matricaria inodora
Family: Asteraceae (Daisy Family)/Compositae
Class: Angiospermae (Angiosperms)
SubclassDicotyledonae (Dicotyledons)
Kingdom: Plantae
Order: Asterales

Superorder:  Asteridae (Daisy Superorder)
Tribe: Anthemideae
GenusMatricaria (Mayweed)
Species:  inodora (without a smell)

Synonym:Corn Feverfew.

Common Names :
• English: Scentless false mayweed, Barnyard daisy, False chamomile, Bachelor’s button
German: Geruchlose Kamille

Habitat :Matricaria inodora is native to Europe.
(Most are very common in the temperate regions of Europe, Asia, and America, as well as in northern and southern Africa, and some are naturalised in Australia. M. occidentalis is native to North America; other species have been introduced there.)

Description:
Matricaria inodora is an annual,growing to a height of about 1 feet.Generally flowers during summer time . It is commonly met with in fields, by the wayside, and on waste patches of ground, and flowers throughout the summer. The name ‘Mayweed’ is misleading, as it will be found in flower right up to the autumn. It is spreading and bunching in its growth, generally about 1 foot in height, but varying a good deal. The leaves, as in all the members of this group, are feather-like in character, springing direct from the main stems without leaf-stalks. The flower-petals are white but the heads are borne singly at the ends of long terminal flower-stems, the centre florets deep yellow on very prominent convex disks and the outer florets having very conspicuous white rays, much larger in proportion to the disk than in most of the allied species. Though compared with several of its allies, it may almost be termed ‘scentless,’ the term is not strictly appropriate as it yields slightly sweet and pleasant, aromatic odour.

Leaves:  The leaves of the plant sometimes have very fine and soft hairs on the upper surface, although the plant is mostly hairless. There is no leaf stalk; leaves grow immediately from the stems. The leaves are pinnate in shape, with many extremely thin lobes, and can be around 1 or 2 inches long (2.5 to 5 centimeters).

Flowers:  Each stem is topped by a single flower head which is usually around 1 inch (2.34 centimeters) in diameter. The flower head is encompassed by between 10 and 18 white ray florets, each with a three-toothed shape; the florets tend to curve downwards around the edges and may occasionally have pistils, although these do not produce fruit. Beneath the flower proper, oval bracts of the plant form an involucre, with soft hairs on each; further bracts are bristled and sit at right angles to the flowers.

Fruits: The fruits are achenes (with no pappus). They are wrinkled, ribbed with ten ridges, and have small glandular bumps across the surface.

Medicinal Uses:

Parts Used: Flowers, leaves.

Constituents: The flowers have been found to contain volatile oil, oxalic, valeric and tannic acids, salts of magnesium, iron, potassium and calcium, colouring matter, a bitter extractive and fatty matter.

 Uses:
The flowers are preferred for internal use, being slightly less disagreeable than the leaves. In hysteria it is used in Europe as an antispasmodic and emmenagogue. Applied to the skin fresh and bruised it is a safe vesicant. A poultice helpful in piles can be made from the herb boiled until soft, or it can be used as a bath or fomentation.

It is administered to induce sleep in asthma. In sick headache or convalescence after fever the extract may be used.

A strong decoction can cause sweating and vomiting. It is said to be nearly as valuable as opium in dysentery. It has also been used in scrofula, dysmennorrhoea and flatulent gastritis.

Humulus lupulus

Botanical name :Humulus lupulus
Family: Cannabaceae
Genus: Humulus
Species: H. lupulus
Kingdom: Plantae
Order: Rosales

Synonyms: Humulus americanus. Humulus volubilis. Humulus vulgaris. Lupulus amarus.

Common names:Hop, Common hop, European Hop,

Habitat :Humulus lupulus is native to Europe, western Asia and North America.

Description:
It is a dioecious, perennial, herbaceous climbing plant which sends up new shoots in early spring and dies back to a cold-hardy rhizome in autumn. Strictly speaking it is a bine rather than a vine, using its own shoots to act as supports for new growth.
The plant grows to 6 m (19ft 8in) at a medium rate. It is not frost tender. It is in flower from Jul to August, and the seeds ripen from Sep to October. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Wind.The plant is not self-fertile.Bloom Color: Green, Yellow. Main Bloom Time: Early fall, Late summer, Mid summer. Form: Spreading or horizontal, Variable spread.It is noted for attracting wildlife.

The female plants produce strobiles, which are cone-like reproductive structures (Anon 1999a). The common and most well-known use of H. lupulus is in the flavoring of beer. Lupulin, a resinous substance found in the strobiles, is added to beer to give the distinct bitter taste (Anon 1999b).

Cultivation:
Landscape Uses:Ground cover, Screen. Easily grown in a good garden soil in sun or semi-shade. Prefers a deep rich loam and a warm sheltered position. Plants can succeed in dry shade if plenty of humus is incorporated into the soil, once established they are also somewhat drought tolerant. Hops are reported to tolerate an annual precipitation of between 31 and 137cm, an annual temperature in the range of 5.6 to 21.3°C and a pH of 4.5 to 8.2. Plants are very hardy tolerating temperatures down to about -20°c when dormant. The young shoots in spring, however, can be damaged by any more than a mild frost. A climbing plant, supporting itself by twining around the branches of other plants. Hops are frequently cultivated, both commercially and on a domestic scale, in temperate zones for their seed heads which have many medicinal qualities and are also used as a flavouring and preservative in beer. There are many named varieties. They grow best between the latitudes of 35 – 51°N and 34 – 43°S, with mean summer temperatures of 16 – 18°C. Generally, for beer making, the unfertilized seed heads are preferred and so most male plants are weeded out. Hops are fairly deep rooted, but with a network of shallow feeding roots. These horizontal feeding roots spread out at depth of 20 – 30 cm in the soil and give rise to fibrous roots in upper layers of soil[269]. The vertical roots develop downwards to a depth of about 150 cm with a spread of 183 – 244 cm and have no fibrous roots. The bruised leaves are refreshingly aromatic whilst the flowers cast a pleasing scent. A food plant for many caterpillars[30]. Dioecious. Male and female plants must be grown if seed is required. Special Features: Edible, Invasive, Naturalizing, Attracts butterflies, Suitable for dried flowers, Inconspicuous flowers or blooms.

Propagation:
Seed – sow spring in a cold frame. Germination is fairly quick. Prick out the seedlings into individual pots as soon as they are large enough to handle and plant out in the summer or following spring. Division in spring as new growth begins. Very easy, you can plant the divisions straight out into their permanent positions if required[K]. Basal cuttings in March. Harvest the shoots when they are about 10 – 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.

Edible Uses: 
Edible Parts: Leaves; Root.
Edible Uses: Drink; Rutin; Tea.

Young leaves and young shoots – cooked. The flavour is unique and, to many tastes, delicious. Young leaves can be eaten in salads. Use before the end of May. The leaves contain rutin. The fleshy rhizomes are sometimes eaten. A tea is made from the leaves and cones. It has a gentle calming effect. The dried flowering heads of female plants are used as a flavouring and preservative in beer. They are also medicinal. The flowering heads are sprinkled with bitter-tasting yellow translucent glands, which appear as a granular substance. This substance prevents gram-negative bacteria from growing in the beer or wort. Much of the hop’s use as a flavouring and medicinal plant depends on the abundance of this powdery substance. The seeds contain gamma-linolenic acid, an essential fatty acid that is said to have many important functions in the human body and is rarely found in plant sources. The essential oil in the flowering heads is used as a flavouring in cereal beverages and mineral waters. Extracts from the plant, and the oil, are used as flavouring in non-alcoholic beverages, frozen dairy desserts, candy, baked goods and puddings, with the highest average maximum use level of 0.072% reported for an extract used in baked goods

Medicinal Uses:

Humulus lupulus has also been used for medicinal purposes. Traditionally, it has been used to aid digestion and as a mild sedative to treat insomnia (Anon. 1999a).
From about 1950 to 1970, claims had been made that hops contained high quantities of estrogens (Fenselau 1973). Fenselau, et. al. (1973), assessed the degree of estrogenic activity in hops. They tested purified essential-oil fractions, alpha and beta bitter acids, and organic solvent extracts for estrogenic activity (Fenselau 1973). They also examined several dilutions by uterine-weight assay in immature female mice (Fenselau 1973). All tests indicated that hops lacked estrogenic activity (Fenselau 1973).

Another study by Fenselau (1976), tested samples of hops to detect for the presence of tetrahydrocannabinol, THC. This psychotropic compound is the active chemical component of Cannabis sativa (marijuana). They used the selected ion mode on a combined gas chromatograph – mass spectrometer to assay for the compound in 17 samples (Fenselau 1976). No THC was found in any of the samples (Fenselau 1976).

In 1989, H. lupulus was one of twelve plants studies for the treatment of diabetes mellitus (Swanston-Flatt 1989). The studies were done in vivo in normal and streptozotocin-induced diabetic mice (Swanston-Flatt 1989). Streptozotocin is an older intravenous chemotherapeutic (Anon. 1999c). It is used in the treatment of symptomatic or progressive metastatic islet and non-islet cell carcinoma of the pancreas (USP 1995). It also has diabetogenic and hyperglycemic effects (USP 1995). It has been shown to induce diabetes and lower pancreatic insulin content in insulin promoter-mB7-l transgenic mice when given in low doses (Harlen 1995). The mice were given preparations of the herb for 28 days (Swanston-Flatt 1989). In normal diabetic mice, the hops showed no effect on their basal plasma glucose and insulin, glucose tolerance, insulin-induced hypoglycemia, and glycated hemoglobin (Swanston-Flatt 1989). In the streptozotocin diabetic mice, the hops did not significantly affect the parameters of glucose homeostasis listed above or in pancreatic insulin concentration (Swanston-Flatt 1989).

Other modern day experimentation has led to the observance of a variety of possible medicinal uses of H. lupulus, including antibacterial activity (Langezaal 1992; Simpson 1992), treatment for gastritis (Krivenko 1989; Torosyan 1974), and even cancer prevention (Anon. 1998, Buhler 1999, Yasukawa 1995).

Two studies were done on the antibacterial and antimicrobial activity of H. lupulus. Simpson (1992) performed experiments on H. lupulus to determine what factors determine its antibacterial activity. It was determined that a decrease in pH caused the greatest stimulation of antibacterial activity in the weak acids (trans-isohumulone, humulone, colupulone and trans-humulinic acid) of the hops plant (Simpson 1992). The trans-isohumulone was found to have the greatest activity (Simpson 1992). Other monovalent cations stimulated activity, but not to the extent observed by protons (Simpson 1992). Divalent cations produced mixed reactions (from little effect to reduced effect) (Simpson 1992.) The activity of the trans-isohumulone was also found to be antagonized by lipids and beta-cyclodextrin (Simpson 1992). Langezaal (1992) did a study on the antimicrobial effects of essential oils and extracts of H. lupulus. He isolated the essential oils by hydrodistillation and the extracts by soaking the strobiles in chloroform (Langezaal 1992). The compounds had anntimicrobial effects against Bacillus subtilis, Staphlococcus aureus and Trichophylon mentagrophytes var. interdigitale but none against Escherichia coli and Candida albicans (Langezaal 1992).

In 1974, Totosyan conducted a study of H. lupulus in 46 chronic hyposecretory gastritis patients. A decoction of H. lupulus was given to the patients and in 36, a positive therapeutic effect was observed (Totosyan 1974). This was due to the high secretory-motor stimulating effect of the hops (Totosyan 1974). Later, another stuliy of this type was done by Krivenko (1989). He gave an herbal complex of H. lupulus, Achillea millefolium, Urtica dioica, Cichorium, Polygonum, Matricaria chamomilla, Helichrysum arenarium, Calendula, and corn stigmas to patients suffering from chronic hyposecretory gastritis, chronic hepatocholecystitis and/or angiocholitis (Krivenko 1989). No results were reported in this document.

Recent research has examined the role of H. lupulus on cancer prevention. Songsan (1990) used spectral methods to establish the structures of isoxanthohumol, xanthohumaol, and two new chalcone derivatives 3-(isoprenyl)-2,4-dihydroxy-4, 6- dimethyoxychalcone and 2,6 dimethyoxy-4,4-dihydroxychalcone. In 1998, xanthohumol was shown to inhibit the activity of the enzyme cytochrome P450, a component in the activation of the uncontrolled division of cancer cells (Anon. 1998). This research, conducted by Buh!er (1999) looked at the effects of the flavonoids and chalcones of hops on cancer chemoprevention and cancer chemotherapy. A study by Yasukawa (1995) looked at the effects of another compound in hops: humulon, on tumor promotion. It was shown that humulon inhibited 12-O-tetradecanoylphorbol-13-acetate (TPA) induced inflammation (Yasukawa 1995). Humulon also had a pronounced inhibition of the tumor promoting factor of TPA on the growth of mouse skin tumors that had been activated by 7, 12-dimethylbenz[a]anthracene (Yasukawa 1995).

It is evident that more research needs to be conducted before proven medicinal significance of H. lupulus can be claimed. Clearly, the emphasis of the research will be on cancer prevention. And in this era, with the discovery of compounds such as Vincristine and Vinblastine in Vinca roseus, the possibility may not be so unrealistic.

Other Uses:

Dye; Essential; Fibre; Paper.

A fine brown dye is obtained from the leaves and flower heads. An essential oil from the female fruiting heads is used in perfumery. Average yields are 0.4 – 0.5%. Extracts of the plant are used in Europe in skin creams and lotions for their alleged skin-softening properties. A fibre is obtained from the stems. Similar to hemp (Cannabis sativa) but not as strong, it is used to make a coarse kind of cloth. It is sometimes used for filler material in corrugated paper or board products, but is unsuited for corrugated paper because of low pulp yield and high chemical requirement, or for production of high-grade pulp for speciality paper. The fibre is very durable but it is difficult to separate, the stems need to be soaked beforehand for a whole winter. A paper can also be made from the fibre, the stems are harvested in the autumn, the leaves removed and the stems steamed until the fibres can be removed. The fibre is cooked for 2 hours with lye and then hand pounded with mallets or ball milled for 2½ hours. The paper is brown in colour
The species is a main ingredient of many beers, and as such is widely cultivated for use by the brewing industry . The fragrant flower cones (hops) impart bitterness and flavor, and also have preservative qualities. The extract is antimicrobial, which makes it useful for making natural deodorant. Hops also contain the potent phytoestrogen, 8-prenylnaringenin, that may have a relative binding affinity to estrogen receptors. Hop also contains myrcene, humulene, xanthohumol, myrcenol, linalool, tannins, and resin.

Known Hazards:  Skin contact with the plant causes dermatitis in sensitive people. Hops dermatitis has long been recognized. Not only hands and face, but legs have suffered purpuric eruptions due to hop picking. Although only 1 in 3,000 workers is estimated to be treated, one in 30 are believed to suffer dermatitis. Dislodged hairs from the plant can irritate the eyes. Sedative effect may worsen depression. Avoid during pregnancy (due to antispasmodic action on uterus). Avoid with breast, uterine and cervical cancers
