Description de la plante

Clinical studies revealed that this tree is a powerful, cost-effective remedy for gastrointestinal ulcers and distress via antimicrobial, anti-inflammatory and sensory afferent-dependent actions. In traditional Amazonian medicine sangre de grado is used as an oral gargle for sore throat, as a vaginal antiseptic after childbirth, equally as a hemostatic, and taken internally for wound healing. In recommended dosages, sangre de grado is deemed non-toxic, and there are no known contraindications or drug interactions.

This ethno-medicinal reddish tree sap is obtained from several species of Croton. The Sangre de grado tree emits blood-red sap that is collected and processed. Sangre de grado can also be sold as a liquid directly from the tree, or the bark may be processed and sold.

Binomial name
Croton lechleri

Croton lechleri is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to northwestern South America. It is commonly known as sangre de grado (Peruvian Spanish), sangre de drago (Ecuadorian Spanish) or sangre de grada (Bolivian Spanish) , both of which translate to "dragon's blood". They refer to this tree's (and several related species') thick red latex.

The latex has medicinal properties, and is used by local peoples as a liquid bandage, applied to seal wounds, as it dries quickly to form a protective skin-like barrier. Its use by native people has led to scientific study and observation of its in vitro antioxidant activity as well as both mutagenic and antimutagenic behavior.

The latex also contains a number of chemicals, including taspine. Oligomeric proanthocyanidins, another kind of chemical contained in the latex, have been investigated for the treatment of HIV-associated diarrhea under the name crofelemer. In January 2013, crofelemer, under the trade name Mytesi, was approved by the FDA for the treatment of non-infectious diarrhea in HIV+ patients.
