Sangre De Grado (Dragon's Blood) for Antimicrobial Properties

Research suggests that Sangre de Grado (Croton lechleri) may possess antiviral and immune-modulating properties, with the available literature indicating it is among the more studied Amazonian medicinal plants in this area. The current evidence base consists of a 2001 narrative review examining the scientific literature on Peruvian Amazon plant medicines, which found preliminary support for these properties but characterized the research as early-stage. Studies indicate that while the findings are directionally positive, the authors of this review explicitly noted that much of the research remains preliminary and that rigorous clinical investigation is still needed before stronger conclusions can be drawn. Overall, the evidence is limited in both quantity and study type, meaning that interest in Sangre de Grado's antimicrobial and antiviral potential remains scientifically plausible but not yet well established.
