Nature and kinds of inflammatory swelling

Distinct from the many swelling-shaped diseases such as granthi and vidradhi, shopha (shotha, swelling) is a disease with its own features arising in connection with skin and flesh; it may be uneven or even, large or small, or compact. It arises from vata, pitta, kapha, their combination (sannipata), blood and external (agantuka) causes, so it is of six kinds.
