The use of the "Christ's crown" latex (Euphorbia splendens var. hislopii) in the hepatic fascioliasis control was evaluated. The evaluation was made analyzing the metacercariae readiness in the grass, using tracer animals in a farm in Taubaté, São Paulo, Brazil. The results, obtained examining feces of 60 animals with "Quatro Tamises" technique, showed significant fall in the infection prevalence during the experience, indicating one more subsidy in the control of the problem.
