Others describe the doṣa's course with intervals of two days, one day, or quotidian differently: / relying on blood, it may also produce quotidian fever;
entering the channels carrying muscle, it produces tertian; / and relying on the pathway of fat, the doṣa also produces quartan.
Quotidian [occurs] daily; tertian skips a day; / that which recurs after resting for two days is quartan.
