Mandukparni (Gotu Kola): Evidence, Dosage & Safety

TL;DR

Mandukparni is Centella asiatica (gotu kola): a different species from brahmi (Bacopa monnieri), though the names are often confused. A 2013 systematic review of eight trials found it may ease signs of chronic venous insufficiency, but most trials were poorly reported. A single-dose study (n=40) showed a blunted startle response, hinting at anxiolytic activity. Evidence is preliminary.

What it is

Read this first: mandukparni is not brahmi. Mandukparni is Centella asiatica (L.) Urb. (syn. Hydrocotyle asiatica L.), a slender, creeping, stoloniferous perennial herb of the family Apiaceae (Umbelliferae), rooting at the nodes and growing in damp places across the tropics (EMA assessment report). The Ayurvedic Pharmacopoeia of India monograph "Mandukaparni (W.P.)" defines the drug as the dried whole plant of Centella asiatica (Linn.) Urban (API text, document view).

True brahmi, by contrast, is Bacopa monnieri: the API defines brahmi as the dried whole plant of Bacopa monnieri, and modern botany places it in a different family (Plantaginaceae). The confusion is real and commercial: the U.S. NIH LiverTox database lists "Brahmi (a name also used for Gotu kola)" among Bacopa's common names, and in North India Centella asiatica is often sold as "Brahmi" even though the API assigns the two plants different official names: Mandukaparni for C. asiatica, Brahmi for B. monnieri (API institutional holding: Wellcome Collection; NIH LiverTox; monograph review citing API). When buying either herb, check the Latin binomial on the label, not just the common name. Our brahmi article covers Bacopa monnieri.

The European Pharmacopoeia defines the herbal substance as the dried, fragmented aerial parts containing not less than 6% total triterpenoid derivatives expressed as asiaticoside: the triterpenes (asiaticoside, madecassoside and their acids) are the characteristic constituents (EMA assessment report).

Traditional use

European regulators' assessment documents long-standing traditional use of the herb, including for wound healing and for venous insufficiency in traditional Asian medicine (EMA assessment report). In classical Ayurveda the plant carries medhya (intellect-promoting) and rasayana (rejuvenative) associations, which is part of why it gets confused with brahmi: but those classical associations are traditional claims, not clinical proof, and the trial evidence is assessed separately below.

What modern research says

Chronic venous insufficiency

The most-studied human use. A 2013 systematic review searched 13 databases for randomized trials of Centella asiatica in chronic venous insufficiency (CVI) and included eight studies: pooled data showed significant improvement in microcirculatory measures (transcutaneous oxygen and carbon-dioxide pressures), rate of ankle swelling, and venoarteriolar response, and the trials without quantitative data reported improvements in leg heaviness, pain, and edema. The authors concluded the herb "may be beneficial" but warned that most studies were inadequately reported with unclear risks of bias, which "may threaten the validity of the conclusions" (Chong & Aziz, Evidence-Based Complementary and Alternative Medicine 2013).

Anxiety — a single-dose experiment

In a double-blind, placebo-controlled study, 40 healthy volunteers received either a single 12 g oral dose of gotu kola or placebo. Compared with placebo, gotu kola significantly attenuated the peak acoustic startle response 30 and 60 minutes after treatment, with no significant effect on self-rated mood, heart rate, or blood pressure. The authors called the findings preliminary and noted it "remains to be seen whether this herb has therapeutic efficacy in the treatment of anxiety syndromes" (Bradwejn et al., Journal of Clinical Psychopharmacology 2000). This is an experimental startle paradigm after one large dose: not evidence that gotu kola treats anxiety disorders.

Cognition

The European assessment is blunt: "there are no grounds to support a well-established use of Centella asiatica in improving cognitive function in humans" (EMA assessment report). Small trials exist, but no established cognitive benefit.

Wound healing

A prospective randomized study in 200 Thai patients with diabetic wounds tested oral Centella asiatica extract capsules as an adjunct: the kind of trial the EMA assessment surveys when reviewing clinical safety and efficacy data (EMA assessment report). Topical triterpene preparations also have a long traditional footprint in wound care. Human evidence that oral gotu kola heals wounds remains limited.

Dosage

The Ayurvedic Pharmacopoeia of India lists 5–10 g for the dried whole-plant drug (API text, document view). The CVI trials used a standardized total triterpenic fraction (TTFCA) of the herb, a different preparation from crude powder, and the anxiety experiment used a single 12 g dose of crude herb (Chong & Aziz 2013; Bradwejn et al. 2000). These preparations are not interchangeable, and none of this is a personal recommendation.

Safety & contraindications

In the CVI trials reviewed, gotu kola was generally tolerated. The reported adverse events were minor stomach pain and nausea that occasionally led to discontinuation, plus one report described as "neurological absence" (as summarized in the EMA assessment). Oral administration has otherwise been associated with occasional gastric complaints and nausea, not significantly different from placebo in the available comparisons (same assessment). Overall human toxicity data remain limited, and longer, well-controlled safety studies are still needed. Talk to a qualified clinician before use, especially if pregnant, breastfeeding, or taking medication.

FAQs

Is mandukparni the same as brahmi?

No. Mandukparni is Centella asiatica (gotu kola, family Apiaceae); brahmi is Bacopa monnieri (family Plantaginaceae): different species, different families. The API gives them different official names, but the trade often confuses them, so check the Latin binomial on the label (API; NIH LiverTox).

Does gotu kola help varicose veins or venous insufficiency?

A 2013 systematic review of eight randomized trials found it may improve microcirculatory measures and symptoms like leg heaviness, pain, and edema: but most trials were poorly reported, so the conclusion is cautious (Chong & Aziz 2013).

Does gotu kola help anxiety?

Only very preliminary evidence: one small study found a single 12 g dose blunted the acoustic startle response in healthy volunteers, without changing self-rated mood (Bradwejn et al. 2000). That is not evidence it treats anxiety disorders.

What dose of mandukparni is used?

The API lists 5–10 g of the dried whole-plant drug; trials used standardized extracts (TTFCA), which are not the same as crude powder. There is no established consumer dose: talk to a qualified practitioner.

Is gotu kola safe?

In small trials it was generally tolerated, with occasional stomach pain or nausea (EMA assessment). Overall human safety data are limited.
