Shankhpushpi
Convolvulus prostratus
Also calledShankhapushpi (Sanskrit)
In older monographsConvolvulus pluricaulis, Convolvulus microphyllus
A small, hairy, spreading herb found throughout India, Shankhpushpi is one of the classical Ayurvedic medhya rasayanas, herbs taken to sharpen memory and intellect, and is used for anxiety, sleeplessness and epilepsy. Its effects on memory, anxiety and mood rest on animal studies; the only controlled human trial found was a small pilot study in menopausal women without a placebo. The Sanskrit name is applied to several different plants in the market.
What it is used for
- Memory and cognitionLimited
Classed in Ayurveda as medhya (intellect-promoting). In rats, root extract inhibited acetylcholinesterase and showed antioxidant effects in scopolamine-induced memory impairment; reviews of the plant cite memory-enhancing and anti-Alzheimer effects mainly from animal and cell studies. No adequate human trials found.1,2,3
- Anxiety and nervous tensionLimited
Used in Ayurvedic formulations for anxiety. Ethanolic and chloroform extracts (200 mg/kg) had anxiolytic effects in mice in the elevated plus maze. Animal data only.1,7
- Low mood and depressionLimited
A chloroform fraction showed antidepressant-like effects in mice (forced swim test), apparently via adrenergic, dopaminergic and serotonergic systems. Animal data only.1
- MenopauseLimited
In a randomised pilot trial in 30 women with menopausal symptoms after hysterectomy, 6 g of powder twice daily for 45 days improved menopause rating scores, quality of life and anxiety about as much as shatavari (Asparagus racemosus) powder; there was no placebo group and no adverse effects were reported.4
- SleeplessnessTraditional
Used in Ayurvedic formulations for sleeplessness; extracts lengthened barbiturate-induced sleeping time in rats.1,7
- Epilepsy and seizuresTraditional
Charaka used the white-flowered Shankhpushpi with brahmi juice, vacha and kushtha for insanity and epilepsy; anticonvulsant effects have been reported in animals.1,3,7

Shankhpushpi
One of the four medhya rasayanas (with mandukaparni, yashtimadhu and guduchi), used alone or in combinations to improve memory and intellect; described in classical texts as sara (laxative), medhya (nootropic), vrsya (aphrodisiac) and rasayana (rejuvenator); used for chronic cough, sleeplessness, epilepsy, hallucinations and anxiety. A shoot decoction is a folk remedy for anaemia and weakness.

Convolvulus prostratus extracts
Studied in animals for anticholinesterase, anxiolytic, antidepressant, sedative, analgesic and neuroprotective effects; sold in India as powders, syrups and tablets.
Active compounds
- convolamine
- alkaloid named among the key bioactive constituents
- scopoletin
- coumarin; a TLC marker that helps distinguish C. pluricaulis from other plants sold as Shankhpushpi
- 4'-methoxy kaempferol, 7-methoxy quercetin, β-sitosterol, hydroxycinnamic acid
- flavonoids, sterol and phenolic acid that, with convolamine and scopoletin, are credited with the nootropic activity
History
Shankhpushpi is one of the four classical medhya rasayanas of Ayurveda. Charaka paired its white-flowered form with brahmi, vacha and kushtha for insanity and epilepsy, and later works such as Chakradatta's Chikitsasangraha and the Kaideva Nighantu repeat the use.
