Overview
Shankhapushpi (Convolvulus pluricaulis) is the foremost Medhya Rasayana (intellect-promoting rejuvenative) in classical Ayurveda. The name derives from its flower resembling a Shankha (conch shell), and this delicate herb holds an unparalleled status in the Ayurvedic tradition as the supreme brain tonic. Charaka Samhita singles out Shankhapushpi as one of four specifically named Medhya Rasayana herbs — a distinction that places it among the most important herbs in the entire materia medica.
While Brahmi is more widely known in modern wellness circles, classical texts actually give Shankhapushpi the higher position among Medhya herbs. Charaka specifically recommends Shankhapushpi Swarasa (fresh juice) as the foremost Medhya Rasayana, surpassing even Brahmi, Mandukaparni, and Yashtimadhu in this specific application.
Botanical Description
Convolvulus pluricaulis is a small, prostrate, branching perennial herb with a woody rootstock. It bears beautiful white to pale pink flowers and grows close to the ground in dry, open habitats. The whole plant is used medicinally.
Important botanical note: There has been considerable debate regarding the correct botanical identity of Shankhapushpi. Several plants have been sold under this name:
- Convolvulus pluricaulis — the most widely accepted identity
- Evolvulus alsinoides — also known as Vishnukranti, used in some traditions
- Clitoria ternatea — Aparajita, sometimes substituted
- Canscora decussata — used in some South Indian traditions
For the purposes of this article, we follow the majority classical and modern Ayurvedic pharmacopoeial standard identifying Shankhapushpi as Convolvulus pluricaulis.
Botanical classification:
- Family: Convolvulaceae
- Sanskrit synonyms: Shankhapushpi, Mangalyakusuma, Shankhahva, Ksheerapushpi, Shankhinee

Classical References
Charaka Samhita — The Medhya Rasayana Passage
The most celebrated reference to Shankhapushpi appears in Charaka Samhita, Chikitsasthana, Chapter 1 (Rasayana Pada), where Charaka names four specific Medhya Rasayana herbs:
- Mandukaparni Swarasa (Centella asiatica juice)
- Yashtimadhu Churna with Ksheera (Licorice powder with milk)
- Guduchi Swarasa (Tinospora cordifolia juice)
- Shankhapushpi Kalka (Shankhapushpi paste)
This passage is one of the most quoted in all of Ayurveda regarding brain health and cognitive support. Charaka further states that Shankhapushpi’s Medhya action is its Prabhava — a specific, unique action that transcends its Rasa-Virya-Vipaka properties.
Charaka also classifies Shankhapushpi in his Vayahsthapana group — the ten supreme longevity-promoting herbs.
