Charak Samhita
नवौ कदाचित् सिध्येतामेतौ पादगुणान्वितौ । स्थविराणां जराकासः सर्वो याप्यः प्रकीर्तितः ॥३०॥
Kshataja kasa is palliable if the patient is strong. If these two diseases(kshataja and kshayaja) are in their initial stage and if all four chikitsa chatushpada are endowed with efficiency, then both of these are curable. All types of kasa are however palliable if the patient is old.
