Which kushthas does the text treat as curable, manageable or incurable?

Detailed answer

Verses 76 and 84 give this scheme. Also incurable are kilasa, tridoshic kushtha, non-discharging pale kushtha in the skin and congenital kushtha (verse 70), pundarika like a white lotus and kakanaka coloured like the bandhuka flower, gold or the bimba fruit (verse 77), and a badly affected child of parents with kushtha (verse 78). Severe eye disease, loss of voice and pus flowing from the sores are the fatal signs (verse 78).
