dāḍimāmalakāmrātakapitthakaramardakān |

āmrācca mātuluṅgācca rasaṃ mṛdvagninā pacet ||

pakvaiḥ snāyusirāmāṃsaiḥ prāyo naśyati hi dhvajaḥ ||

One should cook the juice of pomegranate, āmalaka, āmrātaka, kapittha, and karamarda, / as well as of mango and mātuluṅga, over a gentle fire. / For when the ligaments, vessels, and flesh are cooked, the penis is generally destroyed.
