Sangre de Grado, also known as Dragon’s Blood, is a red sap derived from several Croton species native to the Amazon. Its use for treating scratches and abrasions is supported both by traditional practices in South America and by modern scientific research. The sap is traditionally applied topically to cuts, wounds, and abrasions to promote healing and act as a protective barrier.

Scientifically, multiple studies have validated its wound-healing properties. The resin contains high levels of proanthocyanidins and taspine, compounds demonstrated to have anti-inflammatory, antimicrobial, and healing-promoting effects. Laboratory and animal studies have shown that Sangre de Grado accelerates wound closure, promotes tissue regeneration, and inhibits bacterial growth, thus supporting its traditional use.

For example, a study published in Journal of Ethnopharmacology (2003) found that topical application of Sangre de Grado resin significantly improved the rate of wound healing in rats. Another Phytomedicine (2002) study demonstrated its effectiveness as a barrier and in reducing pain and inflammation. Clinical trials in humans are more limited but suggest similar benefits, particularly in protecting small cuts and abrasions from infection and supporting natural healing processes.

In summary, the use of Sangre de Grado for scratches and abrasions is justified by both longstanding traditional use and a moderate level of scientific evidence, especially from in vitro and animal studies, with some supportive human data.
