Chutney and the fried forms are also quite popular in eastern states of Odisha, Bihar, and West Bengal. Furthermore, the tribes of Rajasthan and Madhya Pradesh (Gonds and Sahariya) also make use of the leaves in chutneys. On the other hand, in Uttar Pradesh, crushed leaves are mixed with curd for eating purposes. The high vitamin C content made it popular among the sailors.
