Still’s disease is an autoimmune disorder featuring inflammation characterised by high spiking fever ,salmon coloured, rash that comes and goes, arthritis along with muscle pain, swelling of lymph nodes and enlargement of spleen and liver. Among these high spiking fever is a cardinal symptom along with the rashes over the body. These characteristics features of still’s disease almost mimics with lakshana of samasannipataj jawara which is evidenced in charaka samhita . Acharya Charaka says that “Yadihasti Tadanyatram” it means the information about disease and medicines (as it is chikitsa pradhan grantha) gathered here we won’t get anywhere and the information about medicine from the other book surly we will get references here. Really it’s time to realised the ancient science is the basic science for the other medicines. Here and attempt is made that by tracing Still’s disease in Charaka Samhita with respect to Samasannipataj jwara.
