By what signs is a prameha patient known to be free of the disease, and when is he called incurable?

Detailed answer

Verse 56 gives these signs of recovery. In contrast, verses 25-27 describe as incurable the patient whose urine flows like fat, ghee, honey or an elephant's rut fluid, who has the complications, boils on vital places, dreams of swimming in or drinking from rivers and seas, and a wasted body; treating such a patient is called futile.
