Referred to as Sangre de Grado, the antibacterial, antiseptic, anti-hemorrhagic, and anti-inflammatory properties of this herbal remedy have been used for hundreds of years by local civilizations living along the Amazon River basin. It has also been diluted and used as an oral remedy for diarrhea, gastrointestinal discomfort, and ulcers. What’s most amazing about this treatment is that it’s derived from a dark red sap found only in trees growing in the Amazonian Rain Forests of Brazil.
The sap acts as an analgesic agent by stopping the activation and stimulation of sensory nerve fibers that send pain signals to the brain. It also inhibits the inflammatory response of tissue to chemicals released by these same nerves when applied externally or taken internally.
A study conducted by the University of Antwerp in Belgium revealed that the sap stimulated wound contraction, helped in scabbing, regenerated skin more rapidly, and assisted in new collagen formation. When applied externally, the sap dries quickly and forms a barrier much like a second skin.
Since much of the research on Sangre de Grado has been performed in the course of developing proprietary drugs, most of this research has not been published or made available to the public.
Research on using Sangre de Grado as a treatment for pain and inflammation was presented at Advancing Children’s Health 2000 – a joint meeting between the American Academy of Pediatrics and the Pediatric Academic Societies.
