Original recordings of in vitro effects of aqueous and ethanol Bidens pilosa leaves extracts on the contractile activity of rat primed estrogenized uterine strip. Seven different volumes of Bidens pilosa aqueous and ethanol extract were injected in the organ bath in presence of Normal Krebs solution cumulatively at 10 minutes intervals, respectively. Contractions are expressed in mg (ordinate). Each concentration is represented by an arrow. Ach = acetylcholine, W= wash with Normal Krebs [2.25mM].
