Sangre de Drago is a medicinal blood like latex tapped by indigenous people from a tree found in the rainforests of the Upper Amazon. The natives apply it externally to cuts to stop bleeding and accelerate healing, to disinfect wounds and skin infections, while forming a protective, flexible liquid bandage when dried. It is also used as a mouthwash for bleeding and ulcerations of the gums, tooth infections and to protect the teeth from cavities. Natives use it quite often to treat diarrhea, gastritis, and ulcers. To date, 4 U.S. patents have been filed on the sap, two for wound healing and two describing the antiviral activity, for use in treating animals and humans infected with respiratory syncytial virus, influenza A, B and C, and Herpes simplex virus. Scientists have since found that as a little as a single drop of Sangre de Drago can diminish pain resulting from insect bites and stings, lacerations, burns, and plant reactions for up to 6 hours. The investigators noted that the sap acts as an analgesic agent by stopping the activation and stimulation of sensory nerve fibers that send pain signals to the brain. These scientist pointed out that it also inhibits the inflammatory response of tissue to chemicals released by these same nerves, and that it does so when applied either externally on the skin or when mixed with water and swallowed to treat gastrointestinal problems.
