Convolvulus Pluricaulis (Shankhpushpi)
Convolvulus pluricaulis, known as Shankhpushpi in Ayurvedic medicine, is one of the most revered brain tonics in the Indian tradition. It has been used for centuries to enhance memory, learning, and concentration, with animal research supporting its nootropic, anxiolytic, and neuroprotective properties.
Benefits
What is Convolvulus Pluricaulis (Shankhpushpi)?
Convolvulus pluricaulis is a perennial herb from the Convolvulaceae (morning glory) family, found throughout India in sandy and rocky terrain. Known as Shankhpushpi (meaning "conch-shaped flower") in Sanskrit, it holds a premier position among the four medhya rasayana (intelligence-promoting) herbs described in classical Ayurvedic texts, alongside Bacopa monnieri, Centella asiatica (gotu kola), and Celastrus paniculatus.
In Ayurveda, Shankhpushpi is classified as a medhya (brain tonic) and rasayana (rejuvenator) herb, prescribed to improve intellect, memory, and mental stamina. It is traditionally given to students, the elderly, and those recovering from mental exhaustion. The whole plant - roots, stems, leaves, and flowers - is used medicinally.
Modern pharmacological research, primarily in animal models, has identified a range of bioactive compounds including flavonoids, glycosides, alkaloids, and triterpenoids. These studies have demonstrated memory-enhancing, anxiolytic, antidepressant, anticonvulsant, and neuroprotective activities, supporting the traditional claims for this herb.
- Acetylcholinesterase inhibition: Extracts of Convolvulus pluricaulis have shown AChE inhibitory activity in animal studies, increasing acetylcholine availability for memory and learning processes.
- Antioxidant neuroprotection: The flavonoid and phenolic content provides significant antioxidant activity, protecting neurons from oxidative stress and lipid peroxidation.
- GABAergic modulation: The herb appears to modulate GABA receptors, contributing to its anxiolytic and anticonvulsant effects. This may underlie the calm focus reported by traditional users.
- Cortisol reduction: Animal studies suggest Shankhpushpi may reduce elevated cortisol levels, supporting cognitive function during chronic stress.
- Thyroid modulation: Some research indicates effects on thyroid hormone levels, which may indirectly influence cognitive function and metabolism.
- Traditional Ayurvedic dose: 3-6 g of whole plant powder per day, taken with milk or honey
- Extract: 250-500 mg of standardised extract, 1-2 times daily
- Syrup: 5-10 ml of Shankhpushpi syrup, 1-2 times daily (a popular commercial form in India)
- Fresh juice: 10-20 ml of fresh plant juice per day (traditional preparation)
- Timing: Traditionally taken in the morning or before study/mental work. Can also be taken before bed for its calming effects.
Shankhpushpi is widely available in Indian herbal pharmacies and increasingly from international Ayurvedic supplement suppliers. Note that the name "Shankhpushpi" is used for different plants in different regions of India.
- Side effects: Generally well tolerated with centuries of traditional use. Mild GI discomfort possible at higher doses.
- Thyroid effects: Some animal studies suggest Shankhpushpi may suppress thyroid function. Those with hypothyroidism or on thyroid medications should exercise caution and consult a doctor.
- Species confusion: The name "Shankhpushpi" is applied to at least four different plants in India (Convolvulus pluricaulis, Evolvulus alsinoides, Clitoria ternatea, Canscora decussata). Ensure the product specifies Convolvulus pluricaulis.
- Pregnancy: Traditionally avoided during pregnancy. Insufficient modern safety data.
- Drug interactions: May interact with thyroid medications, sedatives, and anticholinergic drugs.
