Siddha has always focused on the health needs of the society. The line of treatment in Siddhalaya is unique with its holistic approach in treatment of diseases. It is based on the experience and clinical knowledge of 7 generations of Siddha practitioners starting from Valangai Puli Pandithar, who lived near Coutrallam, about 400 years ago. The clinical experience of the ancestors has been documented on palm leaves and handed over to the current generation of Siddha Physicians at Siddhalaya over a period of time.
