nārīṇāṃ puṣpahṛt tattu kupathyaṃ cāśmatālakam
kuṣmāṇḍatoyasaṃsvinnaṃ tataḥ kṣārajalena vā
cūrṇatoyena vā svinnaṃ dolāyaṃtreṇa śudhyati //

stone-orpiment suppresses the menses of women and is unwholesome. / Steamed with ash-gourd juice, or thereafter with alkaline water / or steamed with lime water in a swing apparatus, it becomes pure.
