Sangre de grado

background

Sangre de grado (the Peruvian name) or sangre de drago (the Ecuadorian name), meaning "blood of the dragon," is a medium-sized tree that grows in the upper Amazon region of Peru, Ecuador, and Colombia. It has large, heart-shaped green leaves and greenish-white flowers. Upon injury to the bark of the tree, a dark red resin spills out of the tree. Sangre de grado is still used in South America as traditional medicine for hemorrhaging and wounds, and as an antiseptic. It is also used for protection against ulcers, including those of the stomach, mouth, throat, and intestines; as an antiviral, anticancer, and antidiarrheal agent; and topically for skin conditions and insect bites.
Compounds isolated from the sap of sangre de grado have been studied for their effects on diarrhea and herpes virus infections. More studies are needed.

Diarrhea (Grade: B)
Sangre de grado has been studied as a treatment for diarrhea, travelers' diarrhea and diarrhea in AIDS patients, with positive results. However, additional research is needed before a firm conclusion can be made.
Herpes virus (Grade: C)
Sangre de grado has been studied as a treatment for herpes virus infection in patients with AIDS with positive results. Additional studies are needed before a conclusion can be made.
