Onion

Onion is a biennial herb of the onion family with hollow, tubular leaves and a swollen underground bulb made of fleshy layers, crowned in its second year by a round cluster of small white flowers. It is the most widely cultivated Allium and is grown across India.

The bulb is used. Ayurveda knows it as Palandu and traditionally uses it in digestive preparations, while onion juice and oil are popular in traditional hair care routines. It is a basic ingredient in Indian cooking.
