Shitapitta is a most common among allergic manifestation on skin. Madhava nidana has explained shitapitta as a vata pradana tridoshaja vyadhi with involvement of rasa (lymp) and rakta (blood) dhatus (tissues). Sheeta means cold and pitta refers to warmth so, shitapitta can be considered as a disease caused by predominance of cold (in vata and kapha doshas) over pitta dosha. Vitiated tridoshas get lodged beneath the skin producing reddish rashes with intense itching and pricking sensation which resembles the urticaria rashes. Being a condition of bahya roga marga (external disease pathway) there are possibilities to get cured easily. Urticaria is a localised dermal oedema secondary to a temporary increase in capillary permeability. Urticaria is considered acute if it persist for less than 6 weeks and chronic if it continues for more than 6 weeks. The present case study is of a 60year old female patient with complaints of skin rashes associated with itching, general weakness of body and joint pain.
