Alkali of sesame and other plants

Sesame, apamarga, gokshura, tala palm, mushkaka, aragvadha and kimshuka are burnt to ash, stirred in water and strained; this alkaline water with shilajit and bida salt added is said to conquer stone. Verse 34 sums up that the physician should overcome even the hardest stone with such ghees, decoctions, alkalis, milks and linctuses, and especially with uttara basti, which a footnote defines as an injection given into the penis or vagina.
