उत्पित्सुरामयो दोषविशेषेणानधिष्ठितः। लिङ्गमव्यक्तमल्पत्वाद्व्याधीनां तद्यथा यथम्॥४॥
which appear earlier to the yet to be manifested disease, not assignable to any dosha specificallybecause of their poor manifestation and mild nature. They are enumerated in the way they manifest in each disease. Notes – Purva rupa is of two kinds. 1- Samanya and 2-Vishishta. The first one comprises of symptoms produced by one or more of the aggravated Dosha, these usually disappear when the disease actually manifests, and these may be common to many diseases. The second one, comprises of the signs and symptoms of the forthcoming diseases itself, appearing mildly and continuing their existence in the further stages of the disease. The ancient texts describe the first kind only under the heading ‘Purvarupa’ in some diseases, as it is difficult for the physician to recognize them and assign them to specific diseases. The second kind may be either mentioned or not, as it is easy for the physician to recognize the characteristic features of the diseases. In some diseases ‘Purvarupa’ is not mentioned at all. This should not be taken to mean that such a disease has no Purvarupa at all, but should be understood that in such diseases the specific features of the disease itself appear as ‘Purvarupa’.
