Effects of the extracts of Desmodium adscendens on anaphylaxis.

Desmodium adscendens, used by herbalists in Ghana for the treatment of asthma, is anti-anaphylactic in vitro. As the plant material is administered orally, in vivo studies of its anti-anaphylactic property were undertaken using the guinea-pig. The results show that both aqueous and ethanolic extracts of D. adscendens, when taken orally, reduce anaphylactic contractions, interfere with histamine-induced contractions, and reduce the amount of smooth muscle stimulating substances released from lung tissue of guinea pigs.
