It's important to note that while "kalonji" refers to the seeds of Nigella sativa, "karivepaku" is the Telugu name for the leaves of a different plant, Murraya koenigii, which is commonly called curry leaf in English.
If you're looking for the Telugu name for the seeds of Nigella sativa, it's "కలువ" (pronounced as "kaluva"). However, this term is not as commonly used as "karivepaku."
