śvitrāṇāṃ &saviśeṣaṃ yoktavyaṃ sarvato viśuddhānām/

For those with śvitra, purgation is to be especially employed after complete purifications;
in śvitra, an excellent purgative is malapū juice taken with jaggery.
Having drunk it and being well oleated, he should expose himself to the heat of sunrays according to strength;
having purged, being thirsty, he should drink peyā for three days.
