Gotu Kola
Ayurvedic herb for cognitive function and skin health
Also known as: Centella asiatica • Indian Pennywort
Overview
Gotu kola (Centella asiatica) is a small herbaceous plant that has been a staple of Ayurvedic and traditional Chinese medicine for thousands of years. It is particularly valued for its effects on cognitive function, wound healing, and circulatory health. The active compounds — asiaticoside, madecassoside, asiatic acid, and madecassic acid — are collectively known as triterpenoid saponins. Research suggests gotu kola may support brain health by promoting nerve growth factor (NGF) production and protecting neurons from oxidative damage. It has also been studied for its ability to improve venous insufficiency and support collagen synthesis. Gotu kola should not be confused with kola nut, which contains caffeine. Gotu kola is caffeine-free and is traditionally considered a calming, restorative herb.
