Botanical Name : Atriplex halimus
Family: Amaranthaceae
Genus: Atriplex
Species:A. halimus
Kingdom:Plantae
Order: Caryophyllales

Common Names: Sea Orach, Saltbush,Mediterranean saltbush, Shrubby orache, Silvery orache

Habitat :Atriplex halimus is native to Europe and Northern Africa, including the Sahara in Morocco. It grows on coastal sands by the sea. Saltmarshes
Description:
Atriplex halimus is an evergreen Shrub growing to 2 m (6ft) by 3 m (9ft) at a medium rate.
It is not frost tender. It is in leaf 12-Jan It is in flower in July. The flowers are monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and are pollinated by Wind.Suitable for: light (sandy) and medium (loamy) soils, prefers well-drained soil and can grow in nutritionally poor soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline and saline soils.
It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought. The plant can tolerate maritime exposure….CLICK & SEE THE PICTURES

Cultivation:
An easily grown plant, it succeeds in full sun in any well-drained but not too fertile soil. Tolerates saline and very alkaline soils[200]. Succeeds in dry soils including pure sands. Plants will grow in semi-shade, though they will soon become leggy in such a position, they are really best in full sun. A very wind hardy plant, it is resistant to salt-laden gales, and can be used as a hedge in maritime areas. Plants dislike very wet climates. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c. This plant is hardier than the foregoing report suggests, it grows well at Hilliers Arboretum in Hampshire where temperatures can fall somewhat lower than -10°c. Plants can be damaged by severe frosts but they soon recover. Resents root disturbance when large. Plants are apt to succumb to winter wet when grown on heavy or rich soils.
Propagation:
Seed – sow April/May in a cold frame in a compost of peat and sand. The seed usually germinates in 1 – 3 weeks at 13°c. Pot up the seedlings when still small into individual pots, grow on in a greenhouse for the first winter and plant out in late spring or early summer after the last expected frosts. The seed is seldom formed. Cuttings of half-ripe wood, July/August in a frame. Very easy. Pot up as soon as they start to root (about 3 weeks) and plant out in their permanent positions late in the following spring. Cuttings of mature wood of the current season’s growth, November/December in a frame. Very easy. Pot up in early spring and plant out in their permanent position in early summer.

Edible Uses:
Leaves – raw or cooked. Some forms are eaten raw. A famine food according to one report, but in modern days it is far from being a famine food, in fact this is one of the more popular crops being grown at ‘The Field’ at present (1993). The leaves have a very nice rather salty flavour, they go well in salads or can be cooked like spinach. When lightly steamed, the leaves retain their crispness and are a delicious spinach substitute. The leaves retain their salty flavour even when grow inland in non-salty soils. The leaves can be used at any time of the year though winter harvesting must be light because the plant is not growing much at this time. Seed – cooked. It can be ground into a meal and used as a thickener in soups, or mixed with cereals in making bread. The seed is small and fiddly. The plant is said to yield an edible manna.

Medicinal Uses:

Carminative.

The shoots are burnt to produce an antacid powder.

Other Uses:
Hedge; Hedge; Soap making; Soil reclamation.

The ash from the burnt plant is used as the alkali in making soap. The plant makes a superb wind-resistant low-growing hedge that can be allowed to grow untrimmed or can be trimmed. It is especially valuable in maritime areas, succeeding right on the coast, though can also be used inland. The plant is extremely tolerant of pruning and can regrow even when cut back into old wood. The plant draws salt out of the soil and so has been used in soil-reclamation projects to de-salinate the soil

Use in antiquity:
According to Jewish tradition, the leaves of Atriplex halimus (orache), known in Mishnaic Hebrew it is said to be the plant gathered and eaten by the poor people who returned out of exile (in circa 352 BCE) to build the Second Temple. Maimonides, in his commentary on Mishnah Kilaim 1:3, as also Ishtori Haparchi in his seminal work, Kaftor u’ferach, both mention the le??n?n by its Arabic name, al-qa?af, a plant so-named to this very day. In the Mishnah (ibid.) we are told that the laws prohibiting the growing of diverse kinds in the same garden furrow do not apply to beets and to orache (Atriplex spp.) that are grown together, although dissimilar

Known Hazards: No member of this genus contains any toxins, all have more or less edible leaves. However, if grown with artificial fertilizers, they may concentrate harmful amounts of nitrates in their leaves.

Osmunda japonica

 

Bmily:otanical Name : Osmunda japonica
Family:  Osmundaceae
Genus: Osmunda
Section:Euosmunda
Species:O. japonica
Kingdom: Plantae
Division: Pteridophyta
Class: Polypodiopsida /Pteridopsida (disputed)
Order: Osmundales

Synonyms: Osmunda nipponica Makino

Common Name : Japanese royal fern or Japanese flowering fern ,Zenmai (In some parts of China it is called juecai in Mandarin), Tibet and Japan it is called zenmai in Japanese.

Habitat :Osmunda japonica is native to E. Asia – China, Japan. It grows in moist places all over Japan.

Description:
Osmunda japonica is a deciduous herbaceous plant which produces separate fertile and sterile fronds. The sterile fronds are spreading, up to 80-100 cm tall, bipinnate, with pinnae 20-30 cm long and pinnules 4-6 cm long and 1.5-2 cm broad; the fertile fronds are erect and shorter, 20-50 cm tall.

It grows in moist woodlands and can tolerate open sunlight only if in very wet soil. Like other ferns, it has no flowers, but rather elaborate sporangia, that very superficially might suggest a flower, from which the alternative name derives.

Like its relative Osmundastrum cinnamomeum (Cinnamon fern), the fertile fronds become brown-colored and contain spores. The sterile (vegetative) fronds resemble in form, another relative, Osmunda regalis (Royal fern).

CLICK & SEE  THE  PICTURES

Rhizome: erect, massive, forming a trunk, occasionally branching, hairs and old stipe bases woven together with black, fibrous roots.

Frond: 50 cm high by 40 cm wide, deciduous, dimorphic, fertile fronds earlier, erect, sterile later, arching, blade/stipe ratio: 5:4 for sterile fronds, 1:1 for fertile fronds.

Stipe: stipules (flared leaf base), unique to the family/genus, pale reddish brown, long lax hairs, but soon glabrous, vascular bundles: 1 in a U-shape where the top of the arms continue to curl.

Blade: 2-pinnate, sterile oblong, widest at the bottom, fertile consisting entirely of sporagia, papery, reddish to light brown hairs, soon falling.

Pinnae: 4 to 6 pair, catadromous; pinnules oblong, to 10 cm; margins minutely dentate; veins free, forked.

Sori: none, indusium: absent, sporangia: large, globose, tan or black when mature, spores green.
Cultivation:
Likes a soil of swamp mud and loamy or fibrous peat, sand and loam. Succeeds in most moist soils, preferring acid conditions. Requires a constant supply of water, doing well by ponds, streams etc. Plants thrive in full sun so long as there is no shortage of moisture in the soil and also in shady situations beneath shrubs etc. Plants are hardy to at least -20°c, they are evergreen in warm winter areas but deciduous elsewhere. Members of this genus are rarely if ever troubled by browsing deer. Closely related to O. regalis.

Propagation :
Spores – they very quickly lose their viability (within 3 days) and are best sown as soon as they are ripe on the surface of a humus-rich sterilized soil in a lightly shaded place in a greenhouse. Keep the compost moist, preferably by putting a plastic bag over the pot. Plants develop very rapidly, pot on small clumps of plantlets as soon as they are large enough to handle and keep humid until they are well established. Do not plant outside until the ferns are at least 2 years old. Cultivars usually come true to type[200]. Division of the rootstock in the dormant season. This is a very strenuous exercise due to the mass of wiry roots

Edible Uses: the young frond of Osmunda japonica is used as a vegetable.

Medicinal  Uses: Not yet known.

Known Hazards: Although no reports of toxicity is yet found for this species, a number of ferns contain carcinogens so some caution is advisable. Many ferns also contain thiaminase, an enzyme that robs the body of its vitamin B complex. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. The enzyme is destroyed by heat or thorough drying, so cooking the plant will remove the thiaminase.

Commiphora Opobalsamum

[amazon_link asins=’B0778HXP7K,B0769C6PHK,1171336160,B01G8ZUEEW,B07B4Y8KZC,1279383682,B07DFRF5SC,B06XDJ7TKD,3659750883′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’b03c1331-7ae0-11e8-851d-213610c66380′]

Botanical Name: Commiphora Opobalsamum
Family:    Burseraceae
Genus:    Commiphora
Kingdom:    Plantae
Order:    Sapindales

Synonyms: Balsamum Meccae var. Judiacum. Balsamum Gileadense. Baume de la Mecque. Balsamodendrum Opobalsamum. Balessan. Bechan. Balsam Tree. Amyris Gileadensis. Amyris Opobalsamum. Balsumodendron Gileadensis. Protium Gileadense. Dossémo.

Part Used: The resinous juice.

Habitat:Commiphora Opobalsamum is native to  countries on both sides of the Red Sea.

Description:
Commiphora Opobalsamum is a small tree, the source of the genuine Balm of Gilead around which so many mystical associations have gathered stands from 10 to 12 feet high, with wandlike, spreading branches. The bark is of a rich brown colour, the leaves, trifoliate, are small and scanty, the flowers unisexual small, and reddish in colour, while the seeds are solitary, yellow, and grooved down one side. It is both rare, and difficult to rear, and is so much valued by the Turks that its importation is prohibited. They have grown the trees in guarded gardens at Matarie, near Cairo, from the days of Prosper Alpin, who wrote the Dialogue of Balm, and the balsam is valued as a cosmetic by the royal ladies. In the Bible, and in the works of Bruce Theophrastes, Galen, and Dioscorides, it is lauded.

CLICK & SEE THE PICTURES 

Leaves in Commiphora are pinnately compound (or very rarely unifoliolate). Many species are armed with spines. Bark is often exfoliating, peeling in thin sheets to reveal colorful, sometimes photosynthetic bark, below. Stems are frequently succulent, especially in species native to drier environments. Flowers are subdioecious and fruits are drupes, usually with a 2-locular ovary (one is abortive). In response to wounding, the stems of many species will exude aromatic resins

The wood is found in small pieces, several kinds being known commercially, but it rapidly loses its odour. The fruit is reddish grey, and the size of a small pea, with an agreeable and aromatic taste. In Europe and America it is so seldom found in a pure state that its use is entirely discontinued .

Constituents:  The liquid balm is turbid whitish, thick, grey and odorous, and becomes solid by exposure. It contains a resin soluble in alcohol, and a principle resembling Bassorin.

Medicinal  Uses:  It has been used in diseases of the urinary tracts, but is said to possess no medicinal properties not found in other balsams.

Boswellia thurifera

[amazon_link asins=’B00Q3IKV6Q,B00O16PEJQ,B000VZX4QG’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’5516b8e2-75a7-11e7-8a4d-bfb09d0e867e’]

Botanical Name :Boswellia thurifera
Family: Burseraceae
Genus: Boswellia
Species: B. serrata
Kingdom: Plantae
Order: Sapindales

Common Names:   Boswellia (Frankincense) , Olibanum, Indian Frankincense, Arabic Frankincense, and Salai guggal

Habitat: Boswellia thurifera  is native to  Arabia, East Africa (particularly Oman, Socotra, Somalia)

Description:
Frankincense is tapped from the small drought-hardy Boswellia trees by slashing the bark, which is called striping, and allowing the exuded resin to bleed out and harden. These hardened resins are called tears. There are several species and varieties of frankincense trees, each producing a slightly different type of resin. Differences in soil and climate create even more diversity of the resin, even within the same species.

click to see the pictures……..(01).…(1).…....(2).……..(3)..……..(4).……....(5).……...

Boswellia Sacra trees are considered unusual for their ability to grow in environments so unforgiving that they sometimes grow out of almost solid rock. Attachment to the rock is accomplished by a bulbous disk-like swelling of the trunk. This feature is slight or absent in trees grown in rocky soil or gravel. The tears from trees growing on rock are considered superior for their more fragrant aroma.

The trees start producing resin when they are about eight to 10 years old. Tapping is done two to three times a year with the final taps producing the best tears due to their higher aromatic terpene, sesquiterpene and diterpene content. Generally speaking, the more opaque resins are the best quality. Fine resin is produced in Yemen and along the northern coast of Somalia, from which the Roman Catholic Church draws its supplies.

Recent studies have indicated that frankincense tree populations are declining, partly due to over-exploitation. Heavily tapped trees produce seeds that germinate at only 16% while seeds of trees that had not been tapped germinate at more than 80%. In addition, burning, grazing, and attacks by the longhorn beetle have reduced the tree population.[4] Conversion (clearing) of frankincense woodlands to agriculture is also a major threat

Quality:
Frankincense comes in many types, and its quality is based on color, purity, aroma, age, and shape. Silver and Hojari are generally considered the highest grades of frankincense. The Omanis themselves generally consider Silver to be a better grade than Hojari, though most Western connoisseurs think that it should be the other way round.[citation needed] This may be due to climatic conditions with the Hojari smelling best in the relatively cold, damp climate of Europe and North America, whereas Silver may well be more suited to the hot dry conditions of Arabia.
click to see Frankincense
Local market information in Oman suggests that the term Hojari encompasses a broad range of high-end frankincense including Silver. Resin value is determined not only by fragrance but also by color and clump size, with lighter color and larger clumps being more highly prized. The most valuable Hojari frankincense locally available in Oman is even more expensive than Somalia’s Maydi frankincense derived from B. frereana (see below). The vast majority of this ultra-high-end B. sacra frankincense is purchased by His Majesty Sultan Qaboos bin Said the ruler of Oman, and is notoriously difficult for western buyers to correctly identify and purchase.

Currently, there are two dissertations which may enable the identification of a few Olibanum species according to their specific secondary metabolism products

Chemical constituents:
These are some of the chemical compounds present in frankincense:

*”acid resin (56 per cent), soluble in alcohol and having the formula C20H32O4″

*gum (similar to gum arabic) 30–36%

*3-acetyl-beta-boswellic acid (Boswellia sacra)

*alpha-boswellic acid (Boswellia sacra)

*4-O-methyl-glucuronic acid (Boswellia sacra)

*incensole acetate

*phellandrene

Medicinal Uses:
Frankincense is used in perfumery and aromatherapy. The essential oil is obtained by steam distillation of the dry resin. Some of the smell of the frankincense smoke are products of pyrolysis.

Frankincense is used in many Christian churches including the Eastern Orthodox, Oriental Orthodox and Catholic churches. According to the gospel of Matthew 2:11, gold, frankincense, and myrrh were among the gifts to Jesus by the biblical magi “from out of the East.” The Judaic, Christian and Islamic faiths have used frankincense mixed with oils to anoint newborn infants and individuals.

Conversely, the growth of Christianity depressed the market for frankincense during the 4th century AD. Desertification made the caravan routes across the Rub’ al Khali or “Empty Quarter” of the Arabian Peninsula more difficult. Additionally, increased raiding by the nomadic Parthians in the Near East caused the frankincense trade to dry up after A.D. 300.

Traditional medicine:
Frankincense resin is edible and is used in traditional medicines in Asia for digestion and healthy skin. For internal consumption, it is recommended that frankincense be translucent, with no black or brown impurities. It is often light yellow with a (very) slight greenish tint. It is often chewed like gum, but it is stickier.

In Ayurvedic medicine Indian frankincense (Boswellia serrata), commonly referred to as “dhoop,” has been used for hundreds of years for treating arthritis, healing wounds, strengthening the female hormone system and purifying the air. The use of frankincense in Ayurveda is called “dhoopan”. In Indian culture, it is suggested that burning frankincense daily in the house brings good health

Frankincense essential oil:
The essential oil of frankincense is produced by steam distillation of the tree resin. The oil’s chemical components are 75% monoterpenes, sesquiterpenes, monoterpenoles, sesquiterpenols, and ketones. It has a good balsamic sweet fragrance, while the Indian frankincense oil has a very fresh smell. Contrary to recent claims, steam or hydro distilled frankincense oil does not contain any boswellic acid as these components (triterpenoids) are non-volatile and too large to come over in the steam distillation process. The chemistry of the essential oil is mainly monoterpenes and sesquiterpenes with small amounts of diterpenoid components being the upper limit in terms of molecular weight.

Perfume:
Olibanum is characterized by a balsamic-spicy, slightly lemon, fragrance of incense, with a conifer-like undertone. It is used in the perfume, cosmetic and pharmaceutical industries.

Medical Research:
For therapy trials in ulcerative colitis, asthma and rheumatoid arthritis there are only isolated reports and pilot studies from which there is not yet sufficient evidence of safety and efficacy. Similarly, the long-term effects and side effects of taking frankincense has not yet been scientifically investigated. Nonetheless, several preliminary studies have been published.
click to see the picture of  FrankinsenceEssOil
A 2008 study reported that frankincense smoke was a psychoactive drug that relieves depression and anxiety in mice. The researchers found that the chemical compound incensole acetate was responsible for the effects.

In a different study, an enriched extract of “Indian Frankincense” (usually Boswellia serrata) was used in a randomized, double-blinded, placebo-controlled study of patients with osteoarthritis. Patients receiving the extract showed significant improvement in their arthritis in as little as seven days. The compound caused no major adverse effects and, according to the study authors, is safe for human consumption and long-term use.

In a study published in 2009, it was reported that “Frankincense oil appears to distinguish cancerous from normal bladder cells and suppress cancer cell viability.”

A 2012 study in healthy volunteers determined that exposure to 11-keto-?-boswellic acid (KBA), a lead boswellic acid in the novel solubilized frankincense extract Boswelan, is increased when taken with food. However, simulations based on a two-compartment pharmacokinetic model with single first-order absorption phase proposed that the observed food interaction loses its relevance for the simulated repeated-dose scenario.

In a 2012 study, researchers found that the “behavioral effect [of insensole actetate] was concomitant to reduced serum corticosterone levels, dose-dependent down-regulation of corticotropin releasing factor and up-regulation of brain derived neurotrophic factor transcripts IV and VI expression in the hippocampus. These data suggest that IA modulates the hypothalamic–pituitary–adrenal (HPA) axis and influences hippocampal gene expression, leading to beneficial behavioral effects supporting its potential as a novel treatment of depressive-like disorders

Botanical Name :Polygonum bistorta or Persicaria bistorta
Family: Polygonaceae
Genus: Persicaria
Species: P. bistorta
Kingdom: Plantae
Order: Caryophyllales
Synonyms: Persicaria bistorta (L.) Samp., Polygonum ampliusculum Gand., Polygonum bistorta L., Polygonum bourdinii Gand., Polygonum carthusianorum Gand., Polygonum ellipticum Willd. ex Spreng., Polygonum pilatense Gand.

Common Name : Bistort or Common Bistort,  Meadow bistort, Snakeweed

Numerous other vernacular names have been recorded for the species in historical texts, though none is used to any extent. Many of the following refer to the plant’s use in making puddings: Adderwort, Dragonwort, Easter giant, Easter ledger, Easter ledges, Easter magiant, Easter man-giant, Gentle dock, Great bistort, Osterick, Oysterloit, Passion dock, Patience dock (this name is also used for Rumex patientia), Patient dock, Pink pokers, Pudding grass, Pudding dock, Red legs, Snakeweed, Twice-writhen, Water ledges.

Habitat :     Polygonum bistorta is native to northern and central Europe, including Britain, mountains of S. Europe, western and central Asia. It grows in damp meadows and by water, especially on acid soils.

Description:
Polygonum bistorta is a perennial plant, growing to 0.5 m (1ft 8in) by 0.5 m (1ft 8in) at a fast rate.   It  blooms  late spring into mid summer, producing tall stems ending in single terminal racemes that are club-like spikes of pink-rose colored flowers.  The seeds ripen from Aug to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.  The racemes are about 2 cm thick and 5-9 cm long and end 1 meter tall,upright growing stems. Plants grow in moist soils and under dry conditions go dormant, losing their foliage until adequate moisture exists again. This species is grown as an ornamental garden plant, especially the form ‘Superba’ which has larger, more showy flowers. Typically alpine plants growing from short, thick rhizomes that branch. The foliage is normally basal with a few smaller leaves produced near the lower end of the flowering stems. The leaves are oblong-ovate or triangular-ovate in shape and narrow at the base. The petioles are broadly winged.

The Latin name “bistorta” refers to the twisted appearance of the root. In Northern England the plant was used to make a bitter pudding in Lent from a combination of the plant’s leaves, oatmeal, egg and other herbs. It is the principal ingredient of dock pudding or Easter-Ledge Pudding.  The root of Bistort can be used to produce an astringent that was used in medicine.

Cultivation:
Landscape Uses: Container, Ground cover. Succeeds in an ordinary garden soil[1] but prefers a moisture retentive not too fertile soil in sun or part shade. The plant repays generous treatment. A very cold-hardy plant, tolerating temperatures down to at least -25°c. Bistort was formerly cultivated as a medicinal and edible plant, though it has now fallen into virtual disuse. Plants are somewhat spreading, forming quite extensive colonies especially in low-lying pastures. They seem to be immune to the predations of rabbits. Special Features: Attractive foliage, Edible, Not North American native, Invasive, Suitable for cut flowers, Suitable for dried flowers.

Propagation:
Seed – sow spring in a cold frame. Germination is usually free and easy. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer if they have reached sufficient size. If not, overwinter them in a cold frame and plant them out the following spring after the last expected frosts. Division in spring or autumn. Very easy, larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Edible Uses::…Edible Parts: Leaves; Root; Seed.
Leaves – raw or cooked. One report says that they are rather bitter[5], but we have found them to have a fairly mild flavour, especially when the leaves are young, though the texture is somewhat chewy when they are eaten raw. They make an excellent substitute for spinach. In Northern England the leaves are an ingredient of a bitter Lenten pudding, called Easter ledger pudding, that is eaten at Lent. The leaves are available from late winter in most years and can be eaten until the early autumn though they become much tougher as the season progresses. The leaves are a good source of vitamins A and C, a nutritional analysis is available. Seed – raw or cooked. The seed is very small and rather fiddly to utilize. Root – raw or cooked. Rich in starch and tannin, it is steeped in water and then roasted in order to reduce the tannin content. It is then said to be a tasty and nutritious food. The root has also been boiled or used in soups and stews and can be dried then ground into a powder and used in making bread. The root contains 30% starch, 1% calcium oxalate and 15 – 36% tannin.

Medicinal Uses:

Bistort is one of the most strongly astringent of all herbs and it is used to contract tissues and staunch blood flow. The root is powerfully astringent, demulcent, diuretic, febrifuge, laxative and strongly styptic. It is gathered in early spring when the leaves are just beginning to shoot, and then dried. It is much used, both internally and externally, in the treatment of internal and external bleeding, diarrhoea, dysentery, cholera etc. It is also taken internally in the treatment of a wide range of complaints including catarrh, cystitis, irritable bowel syndrome, peptic ulcers, ulcerative colitis and excessive menstruation. Externally, it makes a good wash for small burns and wounds, and is used to treat pharyngitis, stomatitis, vaginal discharge, anal fissure etc. A mouth wash or gargle is used to treat spongy gums, mouth ulcers and sore throats. The leaves are astringent and have a great reputation in the treatment of wounds. In Chinese medicine the rhizome is used for: epilepsy, fever, tetanus, carbuncles, snake and mosquito bites, scrofula and cramps in hands and feet . Considered useful in diabetes.

Roots and leaves were used to counteract poisons and to treat malaria and intermittent fevers. Dried and powdered it was applied to cuts and wounds to staunch bleeding, and a decoction in wine was taken for internal bleeding and diarrhea (especially in babies). It was also given to cause sweating and drive out the plague, smallpox, measles and other infectious diseases. Bistort is rich in tannins and one of the best astringents. Taken internally, it is excellent for bleeding, such as from nosebleeds, heavy periods and wounds, and for diarrhea and dysentery. Since it reduces inflammation and mucous secretions it makes a good remedy for colitis and for catarrhal congestion. It was originally recommended in 1917 as a treatment for debility with a tendency towards tuberculosis. It has also been used externally for pharyngitis, stomatitis, vaginal discharge, anal fissure, purulent wounds, hemorrhoids, mouth ulcers and gum disease. Comes well with Geranium maculatum.

Other Uses:......Tannin.……The roots contain up to 21% tannin

Known Hazards:   Although no specific mention has been made for this species, there have been reports that some members of this genus can cause photosensitivity in susceptible people. Many species also contain oxalic acid (the distinctive lemony flavour of sorrel) – whilst not toxic this substance can bind up other minerals making them unavailable to the body and leading to mineral deficiency. Having said that, a number of common foods such as sorrel and rhubarb contain oxalic acid and the leaves of most members of this genus are nutritious and beneficial to eat in moderate quantities. Cooking the leaves will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
