Herb question with subs

Has anyone used shankhapushpi herb specifically convolvulus pluricaulis…since there are different plant derivatives of the herb

when I used it way before subclub, recall was insanely good…like noticeably good in a good way. Learning was easy and fluid.

Here are the benefits if anyone is interested
