Agrimonia eupatoria (L.)
Description: This native British perennial grows up to 60cm tall. Its reddish creeping rootstock produces a hairy erect stem which bears long spikes of bright yellow flowers 5-8mm across, arranged in the axil of a small cleft bract. The leaves are alternate pinnate and stipulate, the lower ones having 3-6 pairs of larger leaflets with 2-3 pairs of smaller leaflets in between. The leaves are resinous beneath and hairy along the veins. The fruits are enclosed within a tough capsule with a circle of hooked spines. Agrimonia grows throughout Britain, Europe, Asia and North America along roadsides, wasteland, hedges and banks.

Therapeutics and Pharmacology: Agrimonia is a digestive tonic; its tannins tone the mucous membranes, improving their secretion and absorption. It is of particular benefit in the treatment of irritation and infection of the digestive tract in children. It is also of use in peptic ulceration and for controlling colitis. The bitter principles regulate the liver and gallbladder function, and in Germany it has been used to treat gallstones and cirrhosis of the liver. It is indicated in gallbladder disease associated with gastric hyperacidity.
Agrimonia is also used to counter high uric acid levels in rheumatism and gout. Internally, it is used in haematuria and externally for wounds and cuts. This action is attributed to the high silica content of the herb. It can be used as a mouthwash or gargle for inflamed gums and sore throats. As a douche, it is used in the treatment of leucorrhoea and it is beneficial as an eyewash for conjunctivitis. A poultice can be used in the external treatment of varicose veins.

Additional Comments: This herb is named after Mithridates Eupator, king of Pontus, who was a famous herbalist. Argemone is a Greek word given to plants which were used to treat ailments affecting the eyes. Pliny referred to it as a 'herb of princely authoritie'. The Anglo-Saxons, who called it garclive, applied it to wounds and believed it could cure warts and snakebites. Chaucer recommends egrimoyne, mugwort and vinegar for 'a bad back' and 'alle woundes'. During the 15th century it was the prime ingredient of 'arquebusade water', a battlefield remedy for gunshot wounds and it is still used today for sprains and bruises. It is an ingredient of 'spring tonics' in many parts of Europe and a popular tisane in France. The whole plant yields a yellow dye. A related variety, A. pilosa, known as xian he cao in China, is used in a similar way to A. eupatoria. It has antibacterial and antiparasitic actions and is used for Trichomonas vaginalis, tapeworm, dysentery and malaria. In traditional Chinese medicine, agrimony is a major herb for stopping bleeding and is used to treat profuse menstruation, internal bleeding and tuberculosis. Chinese research indicates that agrimony can increase blood coagulation by 50%.
