Gotu Kola: Benefits and Uses

Please read first: this article is general educational information, not medical advice. Gotu kola has been associated with liver-related reports and may interact with sedatives and other medications. Talk to your doctor or pharmacist before taking it, particularly if you have a liver condition.

Quick answer on gotu kola

Gotu kola (Centella asiatica) is a low creeping plant with round, fan-shaped leaves that grows in wet ground across Asia. It contains no caffeine and has no botanical relationship to the kola nut, despite the name. It appears in Ayurvedic tradition, in Chinese medicine, and simply as a vegetable in Sri Lankan and Thai cooking. Its research interest centres on a specific group of compounds called triterpenes, and the best-supported findings concern topical and circulatory applications rather than the cognitive ones it is usually marketed for.

Three traditions, one plant

Gotu kola is unusual in showing up independently across several systems.

In Ayurveda it is known as brahmi — confusingly, since that name is also applied to bacopa monnieri, a completely different plant. Both are associated with the mind in Ayurvedic tradition, which is how the name came to be shared, and it is a genuine source of mix-ups in the supplement market. If a product says brahmi, check the Latin binomial.

In traditional Chinese medicine it appears under a different name and framing again. And in Sri Lanka it is simply food, eaten raw in a finely shredded salad called gotu kola sambol, which is about as ordinary a use as a medicinal herb ever gets.

That culinary history is worth noting for the same reason it matters with astragalus. A plant people have eaten as a vegetable has a different practical track record from one that only ever appeared in concentrated form.

Triterpenes, and where the evidence is strongest

Gotu kola's characteristic compounds are a group of triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid. Standardised extracts are commonly specified to total triterpene content, which makes this one of the better-characterised botanicals in terms of knowing what you are buying.

Here is the part most articles get backwards. The strongest evidence for centella concerns topical application — it is used in wound care and dermatological preparations, and is a familiar ingredient in Korean skincare under the name cica. There is also a body of work on venous insufficiency, meaning circulation in the legs.

The cognitive and anxiety-related uses that dominate supplement marketing have a much thinner human evidence base. Some small trials exist. Reviews generally conclude the evidence is insufficient to draw firm conclusions.

We would rather tell you that plainly than repeat the marketing. If cognitive support is what you are after, lion's mane and bacopa both have more relevant research behind them, thin as those are in absolute terms.

The tiger story, and what to do with it

Gotu kola comes with a persistent piece of folklore: that it was observed being eaten by tigers rolling in patches of it to heal their wounds, and that this is how its wound-healing reputation began.

It is a good story and there is no reliable way to verify it. We include it because it is part of how the plant is talked about, not as evidence of anything. The wound-care applications have a modern research basis that stands on its own without the tiger.

This is broadly how we think traditional material should be handled. The history is genuinely interesting and worth knowing. It is not a substitute for a trial, and a page that blurs the two is doing something sloppy.

How it is taken, and who should be careful

Traditionally the fresh leaves are eaten as a vegetable or brewed as a tea. Modern supplements are capsules and standardised extracts, and topical preparations are a substantial market in their own right.

Several cautions deserve attention. Gotu kola has appeared in reports of liver-related adverse effects, and the NIH LiverTox database carries an entry for centella. That is a meaningful signal, and anyone with an existing liver condition should avoid it absent medical advice. Anyone developing jaundice, dark urine, unusual fatigue or abdominal pain while taking it should stop and see a doctor.

It may also be additive with sedative medication, so caution is warranted alongside benzodiazepines, sleep medication or sedating antidepressants. It is generally advised against in pregnancy. And courses are conventionally kept to a few weeks at a time rather than run indefinitely, which is a reasonable default given the evidence available.

The efficient way to check all of this at once is a pharmacist, as set out in supplements and medications.

Frequently asked questions

Does gotu kola contain caffeine? No. Despite the name it has no relationship to the kola nut and contains no caffeine. It is not a stimulant.

Is gotu kola the same as brahmi? Confusingly, the name brahmi is applied to both gotu kola and bacopa monnieri in Ayurvedic usage. They are different plants. Check the Latin binomial on the label.

What is gotu kola best supported for? The strongest evidence concerns topical use in wound care and skin preparations, and there is a body of work on venous circulation. Cognitive and anxiety uses have thinner human evidence.

What are the active compounds in gotu kola? A group of triterpenes including asiaticoside, madecassoside, asiatic acid and madecassic acid. Standardised extracts are often specified to total triterpene content.

Is gotu kola safe for the liver? There have been reports of liver-related adverse effects, and the NIH LiverTox database carries an entry. Anyone with an existing liver condition should avoid it without medical advice.

Can you eat gotu kola? Yes. It is eaten as a leafy vegetable in Sri Lanka and elsewhere in South and Southeast Asia, most familiarly in a finely shredded salad.
