Gotu kola is Centella asiatica, a leafy herb eaten in parts of South and Southeast Asia and used in teas, juices, and extracts. Its triterpenes appear to support collagen remodeling and capillary/venous function, with smaller effects on antioxidant and neurochemical pathways. Human evidence is best for venous symptoms and microcirculation, with smaller and less consistent data for wound repair, scar quality, and cognition. It fits best for adults with heavy legs from long standing, people focused on skin recovery, and older adults seeking modest memory support.

How It Works

Triterpenes such as asiaticoside and madecassoside stimulate fibroblasts and collagen synthesis, which may help wound repair and scar remodeling. They also appear to improve capillary integrity and venous tone, and may modestly affect cholinergic and GABA-related signaling relevant to memory and calmness.
