Croton lechleri Mull. Arg. (Euphorbiaceae) is a traditional medicinal plant which produces a red sap, traditionally known as "Sangre de Drago"; it is used in folk medicine externally for wounds, fractures, and haemorrhoids, internally for intestinal and stomach ulcers and also for the
The immunomodulatory activity of the latex from Croton lechleri (sangre de drago) was determined by in vitro assays. Classical (CP) and alternative (AP) complement pathways activities were determined in human serum. Intracellular generation of reactive oxygen species (ROS) by human polymorphonuclear
Croton lechleri L. (Euphorbiaceae), a plant from the Upper Amazon Valley of Peru, yielded the alkaloid taspine. The anti-inflammatory activity of taspine hydrochloride was studied using the carrageenan-induced pedal edema method, the cotton pellet-induced granuloma method, and the adjuvant
