Gotu Kola and Shankhpushpi: An Ayurvedic Duo for the Mind
Two herbs from the "medhya rasayana" repertoire with complementary strengths: gotu kola for circulation, skin and calm grounding, shankhpushpi for mental clarity and sleep. Here’s why this classic combination holds up, and where the confusion lies.
Gotu kola and shankhpushpi form a traditional combination from the Ayurvedic repertoire of medhya rasayanas, herbs dedicated to the mind, but their strengths don't overlap. Gotu kola (Centella asiatica) mainly acts on circulation, skin and calm grounding; brahmi/">shankhpushpi is more focused on mental clarity and sleep. It's this complementary nature, more than redundancy, that justifies pairing them.
This logic echoes what's already been described for other mind-focused duos like jatamansi and brahmi. It does, however, assume you don't confuse the herbs involved: shankhpushpi isn't always the same botanical species depending on the region, and gotu kola is frequently mixed up with brahmi, a distinct herb whose name is sometimes used interchangeably in the marketplace.
Why combine gotu kola and shankhpushpi?
In Ayurvedic tradition, gotu kola is mainly valued for wound healing, venous circulation (heavy legs) and a calming effect on the nervous system, without directly targeting memory. Shankhpushpi (most often Convolvulus pluricaulis) is, on the other hand, traditionally associated with easing mild anxiety, sleep quality and a form of mental clarity — an effect described as calming without being sedating enough to interfere with daytime functioning.
Combining the two means pairing physical and nervous grounding (gotu kola) with mental clarity and relaxation (shankhpushpi), rather than stacking the same effect twice. This is a different logic from the brahmi and gotu kola duo, where brahmi specifically targets working memory: here, neither herb is a memory "booster" in the strict sense, which makes this combination better suited to an agitated mind than to pure exam preparation.
An important mix-up to avoid
Two naming pitfalls come up often with these herbs. First, shankhpushpi doesn't always refer to the same species: in North India, it's most often Convolvulus pluricaulis, while in some regions and commercial products, the name covers Evolvulus alsinoides, a different plant with traditional uses that are close but not identical. Checking the Latin name on the label avoids a lot of confusion.
Second, gotu kola (Centella asiatica) is very often confused with brahmi (Bacopa monnieri): the two are sometimes sold under the commercial name "brahmi" even though they're two botanically distinct herbs with different actions. Our comparison brahmi vs gotu kola covers this classic mix-up in depth — a useful read before combining gotu kola and shankhpushpi with full knowledge of what you're taking.
Gotu kola and shankhpushpi side by side
| Criterion | Gotu kola (Centella asiatica) | Shankhpushpi (Convolvulus pluricaulis) |
|---|---|---|
| Part used | Aerial parts (leaves, stems) | Whole plant (aerial parts) |
| Main traditional action | Circulation, wound healing, nervous grounding | Mental clarity, calming, sleep |
| Indicative dosage (powder) | 1/2 teaspoon, 1 to 2 times/day | 1/4 to 1/2 teaspoon, 1 to 2 times/day |
| Notable precaution | Caution with liver disease | Caution with sedative treatment |
What does research say?
The scientific literature on gotu kola and cognition is more extensive than for shankhpushpi, but it remains mixed. A randomized double-blind placebo-controlled trial led by Wattanathorn and colleagues (2008, Journal of Ethnopharmacology) in 28 healthy older adults found that a 750 mg/day dose of Centella asiatica extract over two months improved working memory and certain electrophysiological attention markers, with an improvement in self-reported mood (see the study on Google Scholar).
A larger systematic review with meta-analysis, conducted by Puttarak and coauthors (2017, Scientific Reports) across eleven clinical trials, found no significant difference across the cognitive domains tested between Centella asiatica and placebo, while noting a mood improvement (less anger, more perceived alertness) an hour after intake (see the study on Google Scholar). For shankhpushpi, human clinical data remain far scarcer; most available research is preclinical or computer-modeling based. No trial has, moreover, tested the combination of the two herbs itself: the presumed synergy currently rests on tradition, not on dedicated clinical proof.
How to dose this combination in practice
The guidelines below remain indicative traditional practices, not clinically validated dosages.
- As a powder (churna): 1/4 to 1/2 teaspoon of each herb, in warm water or milk, once or twice a day, away from meals.
- As a decoction: gently boil a pinch of each powder in 250 ml (1 cup) of water for 10 to 15 minutes, strain and drink warm, ideally in the morning.
- As combined capsules: follow the dosage indicated by the manufacturer, generally 300 to 500 mg per herb, in one or two doses.
Allow several weeks of regular use before judging any effect on the mind: these are background support herbs, not immediate solutions.
Who is this combination meant for?
- Students and exam periods: a traditional need for mental clarity without excess nervousness or daytime drowsiness;
- People under prolonged mental stress: pairing nervous grounding (gotu kola) with mental relaxation (shankhpushpi) rather than relying on a single lever;
- Seniors concerned about their memory: a traditional supportive use, to fold into an overall healthy lifestyle — our guide on focus and memory details the full range of medhya rasayana routines.
This duo is in no way a substitute for a medical work-up in cases of entrenched cognitive trouble, a diagnosed anxiety disorder, or depression: these situations call for professional follow-up, not just a course of herbs.
Precautions
Gotu kola and shankhpushpi are traditionally well tolerated in occasional use and at moderate doses, but safety data remain limited for both, especially over extended courses. As a precaution: avoid during pregnancy and breastfeeding for lack of sufficient data, avoid in young children without medical advice, and discuss with a doctor if on sedative or anti-anxiety treatment, since an interaction can't be ruled out for either herb. Gotu kola calls for particular caution with liver disease. Neither of these two herbs cures a diagnosed anxiety disorder, chronic sleep disorder, or cognitive decline — they are traditional supports, not treatments.

Your questions about gotu kola and shankhpushpi
Can you take gotu kola and shankhpushpi together every day?
Yes, in courses of several weeks followed by a break, following the traditional logic. Start at a moderate dose to check tolerance of each herb separately if possible. The precautions (pregnancy, children, sedative treatments) remain valid throughout the course.
Are shankhpushpi and gotu kola the same plant?
No, they are two botanically distinct plants. Gotu kola is Centella asiatica; shankhpushpi most often refers to Convolvulus pluricaulis, sometimes Evolvulus alsinoides depending on region. They are sometimes wrongly confused with brahmi (Bacopa monnieri) in the marketplace.
Is this combination effective for memory?
Tradition recommends it mainly for mental clarity and calming, not specifically for working memory the way brahmi is. Studies on gotu kola show mixed results depending on the trial, and human data on shankhpushpi remain limited.
How long before you feel an effect?
Allow several weeks of regular use before judging any effect on the mind, as with most herbs in this repertoire. Neither herb acts within days; if nothing has changed after two months, it’s worth reassessing the approach.
Can this combination replace treatment for anxiety?
No, never. In cases of diagnosed anxiety disorder, depression, or entrenched cognitive trouble, medical or psychological follow-up remains essential. These herbs may possibly support a prescribed treatment alongside it, but should never replace it or delay appropriate care.
