What it is
Gotu Kola is a small, ground-creeping plant used in Ayurvedic and traditional Chinese medicine, distinct from kola nut, valued as a "brain tonic" and for wound healing.
Why people take it
Cognitive resilience in aging is a key longevity-adjacent outcome, and Centella has a reasonably long track record of human trials, including in stroke recovery and elderly cognition contexts, making it one of the better-studied cognitive-aging botanicals.
Our verdict
A metaanalys of 11 RCTs found the evidence for clear cognitive benefit isn't strong, though there is more consistent support for improved mood and alertness. A comparative post-stroke trial found it performed comparably to folic acid for vascular cognitive impairment — a modest but real signal.
Structure & class
Centella asiatica extracts are typically standardized for triterpenoid content (asiaticoside, madecassoside, asiatic acid, madecassic acid).
Mechanism & clinical data
A systematisk översikt and metaanalys of 11 RCTs (Puttarak et al. 2017) concluded there is not strong evidence for cognitive function improvement specifically, but the herb does appear to improve mood and alertness. A dose-ranging study testing 250/500/750 mg daily doses found 750 mg produced the greatest effect on mood/cognition in elderly subjects (n=28, 2 months). A comparative post-stroke trial (n=48) using 750 mg or 1000 mg/day over 6 weeks found effects on vascular cognitive impairment comparable to folic acid. An anxiolytic study found a single 12 g dose reduced acoustic startle response in 40 subjects.
Pharmacokinetics
Limited human pharmacokinetic data; asiaticoside and related triterpenoids have variable oral bioavailability depending on extract preparation.
Dose & forms
What to watch out for
maj cause mild GI upset or headache in some users; the EU classified high-purity Gotu Kola extracts as an unauthorized Novel Food as of the januari 2026 review, alongside cycloastragenol.

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in april 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.
