The Siddha System of Medicine (Traditional Tamil System of medicine) has been prevalent in the ancient Tamil land, since B.C. 10,000 to B.C. 4,000. As per the textual and archaeological evidences which indicate the remote antiquity of the Dravidian civilization of the erstwhile submerged land Kumarikandam that is the Lemuria continent situated in the Indian ocean, the Siddha System of Medicine is contemporaneous with those of the submerged lands Egyptian, Mesopotamian, Chinese and Grecian medicines.

The uniqueness of Siddha System is evident by its continuous service to the humanity for more than 5000 years in combating diseases and also in maintaining its physical, mental and moral health while many of its contemporaries had become extinct long ago.

The basic principle of ‘Universe is a macrocosm and Man is microcosm’ has been accepted by this science. Siddha system is based on 96 principles, which have been divided in three groups. The first and second group consists of 30 principles each while the third group has 36 principles.

In Siddha, Yoga is practiced as a therapeutic  technique aimed at bringing alignment in the lives of patients through meditation. It aims at bringing about divine consciousness. Siddha yoga teaches people to live life in the exact way and practice correct actions in all situations. It is about internal development, self-improvement and brings about a change in a person’s attitude and actions. Siddha yoga is also said to make a person healthier by curing physical as well as mental diseases. This is based on an ancient belief that the sufferings that we face now are a result of the karma of our past lives.
