Overview

Gotu Kola (Centella asiatica) is a creeping herb used for centuries in traditional Ayurvedic and Chinese medicine, valued primarily for skin and circulatory support. Unlike a lot of traditional botanicals that rely entirely on historical use with little modern research, Gotu Kola has a genuinely useful body of clinical evidence behind its most established use case: wound healing, largely via topical application.

It's also studied — with more mixed results — for chronic venous insufficiency (poor circulation in the legs, often showing as varicose veins or swelling) and, traditionally, for general cognitive and stress support, though that oral use case has thinner clinical backing than the wound-healing research. The honest picture is that Gotu Kola's strongest evidence is specific to skin and topical application, not a broad "brain and body tonic" the way it's sometimes marketed.

Potential Benefits

Wound Healing Support

A 2022 systematic review found supportive evidence for topical Centella asiatica improving wound healing outcomes.

Collagen Production

Proposed to stimulate collagen synthesis at the site of application, part of the mechanism behind its wound and skin research.

Circulatory Support

Studied for chronic venous insufficiency, with some trials showing favorable results, though findings across studies are mixed.

Long Traditional Use History

Centuries of documented use in Ayurvedic and traditional Chinese medicine for skin and general wellness.

Typical Dosage

Oral (Circulation Studies)

60–180mg per day

The range reflected in the small number of controlled venous-insufficiency trials

Topical

Follow product label directions

Concentration varies widely between creams and extracts — check the labeled percentage

Pro Tips

For a skin or wound-healing goal specifically, a topical product has stronger direct evidence than an oral capsule
For circulation support, expect a modest, not dramatic, effect based on the mixed trial results available
Look for standardized extracts (often listing triterpenoid content) for more consistent dosing
Don't confuse this with kola nut — despite the similar name, they're unrelated plants with different effects

Research Snapshot

A 2022 systematic review of the available research on Centella asiatica and wound healing found supportive evidence for its use, particularly in topical form, with proposed mechanisms including stimulation of collagen synthesis and support for new blood vessel formation (angiogenesis) at the wound site. The review is a useful example of a traditional botanical with an actual, current systematic evidence base behind its most specific use case, rather than relying solely on historical use.

How Gotu Kola Compares

Ingredient	Best For	Key Difference
Gotu Kola	Wound Healing, Circulation	Strongest evidence is topical, not oral
Collagen	Skin, Joint Support	A finished protein rather than a collagen-stimulating botanical
Grape Seed Extract	Circulation, Antioxidant Support	Different mechanism, also studied for venous health
Ginkgo Biloba	Circulation, Cognitive Support	Broader, longer research history for circulation specifically

These are the most common comparisons our customers ask about in-store.

Frequently Asked Questions

Does Gotu Kola actually help wound healing?

A 2022 systematic review of the available research found supportive evidence for Centella asiatica improving wound healing, largely through topical application, with proposed mechanisms including stimulating collagen production and supporting the formation of new blood vessels at the wound site. Most of the strongest evidence is for topical use rather than oral supplementation specifically.

Is Gotu Kola good for circulation and varicose veins?

There's a reasonable body of research on Centella asiatica for chronic venous insufficiency, with some trials showing favorable results on symptoms and subjective assessment, though results across the small number of available controlled trials have been mixed rather than uniformly positive. It's a genuine area of interest, not a settled, guaranteed benefit.

Should I take Gotu Kola orally or use it topically?

It depends on the goal. The wound-healing and skin research is strongest for topical creams and extracts applied directly to the area. Oral supplementation is more commonly used for the circulation and venous-insufficiency use case, and traditionally for general cognitive and stress-related purposes, though that oral cognitive research is less robust than the topical wound-healing data.
