2003 MAR 13 - (NewsRx.com & NewsRx.net) -- Powder from Derris brevipes variety coriacea prevents embryonic implantation.

According to recent research from India, "traditional physicians in and around Kotagiri village near Ootacamund, use a mixture of powdered roots of Cassia occidentalis, Derris brevipes variety coriacea and Justicia simplex to control female fertility."

"A mixture of powdered roots of these three plants, powdered root of Derris brevipes variety coriacea and its ethanolic extract were screened for antifertility activity in proven fertile female rats at 200 and 600 mg/kg body weight, respectively and given orally on D1-7 of pregnancy," wrote S. Badami and colleagues, JSS College of Pharmacy.

"Both doses of the root powder of Derris brevipes variety coriacea showed 50% anti-implantation activity and also a significant reduction in the number of litters born," said Badami and coauthors.

"The ethanolic extract exhibited 40% anti-implantation activity when given orally at 600 mg/kg body weight. The rats, which continued their pregnancy, did not deliver any litters after their full term. Hence, the combined antifertility (anti-implantation and abortifacient) activity of the ethanolic extract was 100%."
