A pure natural resin extracted from the sangre de grado tree (Croton lechleri) which is also called "dragon's blood." Sangre de grado resin is a storehouse of plant chemicals including proanthocyanidins (antioxidants), simple phenols, diterpenes, phytosterols, and biologically active alkaloids and lignans. Scientists have attributed many of the biologically active properties of the resin to two main "active" constituents: an alkaloid named taspine, and a lignan named dimethylcedrusine.*
For more complete information on this powerful plant of the rainforest, please see the Plant Database File on Sangre de Grado.
Raintree Nutrition's sangre de grado resin has been sustainably wild-harvested in the Peruvian Amazon. It is rich in active and beneficial phytochemicals which occur naturally in this plant and is unconditionally guaranteed. Raintree's supply of sangre de grado comes from the high jungle of Peru where new organic cultivation programs with medicinal plants are replacing old coca plantations and providing new sources of income for poor farmers on their existing lands.
Traditional Uses:* to stop bleeding and to seal, and heal wounds, burns, cuts, tooth extractions; for herpes virus ulcers (taken internally and applied topically); for skin fungi, rashes, and dermatitis; for insect bites, poison ivy and other itchy or allergic skin reactions; for stomach ulcers, ulcerative colitis, dysentery and diarrhea
