The use of sulphur with the juice of jātī along with honey is supreme; / and copper pyrite with cow's urine destroys the seventeen types of kuṣṭha. / Or the use of processed sulphur or suvarṇamākṣika is best; / one afflicted with kuṣṭha should take properly prepared and stabilized mercury to eradicate all diseases, / or combined with diamond and śilājatu, or combined with yogarāja; / the kuṣṭha patient, having curbed himself, should continually consume it to pacify all diseases.
