Brahmi (Centella Asiatica / Gotu Kola) for Wound Healing

Research suggests that Centella asiatica and its key active compounds — particularly asiaticoside, madecassoside, asiatic acid, and madecassic acid — promote wound healing through several complementary mechanisms, including stimulating collagen and fibronectin production, supporting fibroblast activity, reducing inflammation, enhancing angiogenesis, and providing antioxidant protection. Studies indicate that the available evidence base consists primarily of laboratory investigations, animal studies, formulation research, and reviews, with a smaller number of clinical trials; the overall direction of findings is consistently supportive, though independent replication and large-scale human trials remain limited. More recent research has focused on novel delivery systems such as hydrogels, nanostructures, and microneedle patches, which appear to improve the bioavailability and effectiveness of these compounds in specific wound contexts including diabetic ulcers, burns, and hypertrophic scars. A 2015 review notably emphasized that human clinical data are still sparse and that factors such as plant growing conditions and processing methods can meaningfully affect the bioactive content of Centella asiatica preparations, underscoring the need for continued clinical investigation before firm conclusions can be drawn.
