Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Alterative  Antitumor  Cholagogue  Depurative  Diaphoretic  Diuretic  Emetic  Expectorant  
Febrifuge  Homeopathy  Laxative  Purgative  Tonic

Hemp agrimony has been employed chiefly as a detoxifying herb for fevers, colds, flu and other viral conditions. It also stimulates the removal of waste products via the kidneys[254]. Due to its content of alkaloids, the plant should only be used under professional supervision[254]. The leaves and flowering tops are alterative, cholagogue, depurative, diuretic, emetic, expectorant, febrifuge, purgative and tonic[4, 7, 9, 21, 46, 238]. The plant has a long history of use as a gentle laxative that does not provoke irritation[7], though excessive doses cause purging and vomiting[238]. A tea made from the dried leaves will give prompt relief if taken at the onset of influenza[4]. Recent research has shown that the plant might have anti-tumour activity, though the plant also contains pyrrolizidine alkaloids that can cause damage or cancer to the liver[238]. The plant is harvested in the summer and dried for later use[7]. The roots are diaphoretic, laxative and tonic[7]. They are harvested in the autumn and dried for later use[238]. Recently the plant has been found of use as an immune system stimulant, helping to maintain resistance to acute viral and other infections[254]. A homeopathic remedy is made from the leaves[4]. It is used in the treatment of influenza and feverish chills[4] and also for disorders of the liver, spleen and gall bladder[9].

Cultivation details

An easily grown plant[233], it succeeds in ordinary garden soil in sun or part shade[200]. Prefers a rich moist soil[187]. Grows well in marshy soils[21]. Plants are hardy to about -25°c[187]. A very ornamental plant[1], it has a pleasant aromatic smell when cut[4]. Often found as a weed in British gardens, it can be allowed to naturalize in short grass in the wild garden[233]. Plants seem to be immune to the predations of rabbits[233]. An excellent bee and butterfly plant[24, 108].

Plant Propagation

Seed - sow spring in a cold frame and only just cover the seed. Prick out the seedlings into individual pots when they are large enough to handle and plant them out into their permanent positions in the summer. If you have sufficient seed it can be sown outdoors in situ. Division in spring or autumn[111]. Very easy, the clumps can be replanted direct into their permanent positions.

This plant is called Bee Sut in Burmese and at present used in Myanmar to cure many diseases. Boiled for 24 hours in several pots of water for one batch of planbts (flowers, leves, stems, roots, everything) and very thick liquid obtained in boiled down into a black, thick paste. Taken mixed with honey, a demitasse spoonful each day followed by a mug of hot water, NEVER cold water. No bathing (shpwer) for an hour after taking it. This medicine induces presipration that cleans out toxins in the body.

The Hemp Agrimony we have in Myanmar called Bee Sut that we use for medicine has small yellow flowers that bloom seoperately (not in clusters. The flowers are like buds: 0.8 cm from top to bottom. Leaves are tapered, saw tooth edges. We cook them in sour soups made with ripe Tamarind fruit pulp and dried prawns or fish. I have sent an earlier email but checking on other sitres found the flower of the same name Hemp Agrimony clusters of pink with pointed leaves.

Alot of eupatorium species contain amabiline which is hepatoxic. Even tho E. purpureum and E. cannabinum ( the first contains less amabilin ) have hepaprotective effects in dosages large enough have significant cytotoxicity and hepatoxicity. caution is advised.
