BrhatTrayis have quoted ‘Sigru’ extensively in their works. Generally its bark is useful for krimi,seeds are used for Nasya Karma and leaves are for Sveda.

Nighantu texts describe sigrubija as svetamarica. The author is of the opinion that svetaMarica may not be the seeds of Sigru. The unprocessed fruits of Piper nigrum will be white in colour are probably interpreted as the seeds of Sigru. Leaves of Sigru are considered to be Sukrala and its seeds are Avrsya.
