Evolvulus alsinoides is one of the four herbs that is given the common name of Shankhapushpi, and appears to be a nootropic agent with comparable potency to Piracetam in otherwise healthy young rats. The mechanisms and exact bioactives underlying these benefits are not currently known, but seem to be localized more in the ethanolic extract and are thought to be alkaloids. There is no human data on this plant at this moment in time.
Beyond the memory enhancing properties evolvulus appears to have general anti-inflammatory, adaptogenic, and neuroprotective properties in the brain following oral ingestion and high doses may confer a sedative property. However, there is insufficient evidence to compare the efficacy of evolvulus against other herbs to see if a role for this herb exists or not. The lack of known bioactive limits research on it.
