About Climbing Brinjal (Sundaikkai)

Climbing Brinjal (Sundaikkai) (Solanum torvum) is a herb used in the Siddha Medicine tradition to help with Diabetes, Digestive Issues, Kidney Support, and Liver Support. The aerial parts and leaves are the parts traditionally used, taken internally.

Botanical background

Solanum torvum is a bushy, erect and spiny perennial plant used horticulturally as a rootstock for eggplant. Grafted plants are very vigorous and tolerate diseases affecting the root system, thus allowing the crop to continue for a second year.

Quality tips

When buying Climbing Brinjal (Sundaikkai), look for: certified organic labelling, clearly stated country of origin, third-party lab testing for heavy metals and pesticides, and a batch expiry date. Standardised extracts offer consistent dosing; bulk dried herbs are more economical for regular use. Avoid very cheap, unlabelled products — quality varies enormously.
