Indian Herbs

Kadipata

Herbs are those plants which are either decorative, fragrant, medicinal or culinary. The seed plants of which the stems do not become woody, but remain more or less soft. 

But this definition excludes some like the fragrant Curry Leaves - which is a woody tree and not a soft shrub or herb. Curry leaves also known as Kadipata, Kadhilimb, Karbeo are widely used in Indian cooking.
Cilantro, Mint and Kasoori Methi are the most widely used herbs in Indian Cuisine.

Fresh leaves are the herb and its seeds are used as a spice. Coriander seeds are an indispensable part of the spice combination known as Curry Powder.
