Kanniyakumari Nannari has been proposed for a Geographical Indication tag.
Kanniyakumari district is known for Nannari, a herb valued for its cooling properties and traditional use for treating mouth ulcers.
The root of this Nannari is thicker, more aromatic, and deeper in colour than regular Nannari and is sun-dried, cleaned, and stored for medicinal and culinary use.
The Kani tribe of the Southern Western Ghats has traditionally used Hemidesmus indicus in Siddha and Ayurvedic medicine as a blood purifier, body coolant, and digestive aid.
