Gotu Kola

Centella asiatica, known as gotu kola, is a perennial herb with slender creeping stems and rounded, fan-shaped leaves that grows low to the ground in damp, tropical, and subtropical environments. It is native to the Indian subcontinent, Southeast Asia, parts of Australia, and other warm regions, and it is used both as a food and as a medicinal plant. In several Asian cuisines the leaves are eaten raw in salads, juices, and other dishes, while in traditional medicine the whole plant has long been employed for a variety of purposes ^[1].

The characteristic constituents of gotu kola are pentacyclic triterpenoids and their sugar-linked glycosides. The most studied are the saponins asiaticoside and madecassoside, together with their corresponding aglycones, asiatic acid and madecassic acid; asiaticoside and madecassoside are recognized as marker compounds for the plant in pharmacopeias ^[1]. Standardized extracts, sometimes described as titrated extracts of Centella asiatica, concentrate these triterpene fractions, which are credited with the plant's effects on connective tissue and blood vessels ^[2].

Gotu kola is traditionally valued for promoting wound healing and healthy skin and as a restorative herb thought to aid cognition and calm the mind. Modern laboratory and clinical research has explored these uses, reporting that its triterpenoids can influence collagen production and support the healing of wounds and scars, and that standardized extracts may benefit the microcirculation in conditions such as chronic venous insufficiency ^[1][2]. Reviews also describe neuroprotective, anti-inflammatory, antioxidant, and anxiety-related effects in experimental models, and the plant is widely used in cosmetics for skin hydration, soothing, and the appearance of scars ^[1][2]. As with many herbal products, much of the evidence comes from laboratory studies and small trials, so conclusions about clinical benefit remain cautious.

Gotu kola is marketed as a dietary supplement and cosmetic ingredient rather than an approved medicine in most countries, and it is available as dried herb, teas, capsules, tinctures, and topical creams. It is generally considered well tolerated when used appropriately, but reported adverse effects include allergic skin reactions with topical use and, uncommonly, liver-related problems associated with prolonged oral use, so extended use warrants care ^[1]. It should be distinguished from unrelated plants and from the kola nut, with which it shares no botanical relationship despite the similar name.

Generally well tolerated, with occasional GI upset, drowsiness, or skin irritation with topical use. High doses or long-term use have raised rare concerns about liver stress, so avoid excessive use and cycle if using long term. Avoid in pregnancy and with liver disease.
