Gotu Kola extract concentrates triterpenoids like asiatic acid, madecassic acid, and asiaticoside. This standardized form aims to help maintain collagen and support microcirculation. Solid, large-scale evidence remains sparse.
People turn to it mainly for skin concerns such as scars and stretch marks, or for mild vein tone support. Most published clinical work uses 60 to 120 mg of a standardized extract. Raw leaf doses run much higher, since this data does not apply to pure isolated triterpenoids.
Pregnant or breastfeeding women should avoid it. The herb may slow blood clotting, so stop taking it two weeks before any scheduled surgery. Sun sensitivity can rise while using it, and high doses sometimes trigger headache or dizziness.
