*''Kushtha'' is the result of combined and simultaneous involvement of all the three ''dosha'' and subsequently vitiation of the four body constituents i.e. ''rasa'' (''twak'', or skin), ''mamsa''(muscle tissue), ''rakta''(blood), and ''lasika''(lymph).

*There can be infinite clinical presentations of ''kushtha'' (skin diseases) depending upon severity of combination of abovementioned vitiating factors.

*While diagnosing the severity of ''kushtha'', the depth of lesion can be assessed according to involvement of skin, muscle, blood and lymph respectively. The treatment should be planned accordingly targeting these constitutes and based upon predominantly vitiated ''dosha''.

*The varieties in vitiated qualities of ''doshas'' (like ''ruksha'' etc.) depend upon dietary and lifestyle causative factors. ''Kushtha'' can be classified based upon the criteria like specific sensation in skin, change in color of skin (pigmentation), site of lesion, spread of lesion, clinical features.

*Continuous exposure to change in temperature (thermal sensitivity), change in fluid volume and muscle mass inside body, incompatible dietary and lifestyle factors are main causative factors of ''kushtha''. Similarly sudden changes in above factors may lead to acute condition of skin disease.

*If the curable ''kushtha'' are not timely treated, it leads to favorable environment to growth of micro-organisms. The micro-organisms grow on the vitiated ''twak, rakta, mamsa,'' and ''lasika'' leading to various severe skin lesions.

*The curable disease can become incurable due to improper management, exposure to causative factors and aggravation of ''dosha''. However, the incurable diseases are never curable.

Three chapters are devoted to dermatological disorders, present chapter and [[Chikitsa Sthana]] chapter 7 ([[Kushtha Chikitsa]]) and 21([[Visarpa Chikitsa]]). The present chapter deals with seven types of ''kushtha'', while in [[Kushtha Chikitsa]], all eighteen types have been described and have been given the name of ''Mahakushtha'' (major) and ''Kshudra kushtha'' (Minor). After reviewing the symptoms of seven major types it is clear that it covers a progressive disorder of skin leading to loss of organs and impaired sensation (sensory neuropathy). According to some commentators ''Kshudra kushtha'' is a  group of mild and localized skin diseases, which runs a chronic course.
