<pañcamaḥ prakāraḥ>
dhuttūrakadravairmardyaṃ dinaṃ gandhāṃśasūtakam /
andhamūṣāgataṃ svedyaṃ bhūdhare mūrchito dināt //

<Fifth method>
Quicksilver with an equal part of sulfur should be ground with dhuttūra juices for a day;
placed inside a blind crucible, it should be fomented in a bhūdhara pit furnace; it is swooned after a day.
