Research Gist
Shankhpushpi (Convolvulus pluricaulis) has long been used in India as a nerve tonic. This study examined whether it could protect the brain against long-term exposure to aluminium, a metal that causes oxidative damage and disrupts nerve signalling. Rats received aluminium chloride daily for three months, with or without an aqueous Shankhpushpi extract, and the results were compared with rivastigmine, a reference compound. The extract reduced the rise in acetylcholinesterase activity caused by aluminium and prevented the decline in Na+/K+ ATPase, an enzyme essential for healthy nerve function. It also prevented damage to fats and proteins in brain tissue and restored the brain's own antioxidant enzymes. Levels of genes linked to healthy nerve signalling and nerve growth — including the muscarinic M1 receptor, choline acetyltransferase and NGF-TrkA — were preserved. These protective effects were also visible under the microscope.
Key Learnings
- Shankhpushpi extract protected brain tissue from aluminium-induced oxidative damage.
- The brain's own antioxidant enzymes were restored.
- Enzymes essential for healthy nerve function were maintained.
- Genes linked to nerve signalling and nerve growth factor were preserved.
- This was a rat study using a toxin model — it does not establish the same effects in people.
