It should be known that mind exerts great influence on the body for the spirit that works through the primordial material essence of mind is endowed with great energy. The ancient Siddhars knew the scientific truth by their meditation and worked wonders through their mental force.

The Siddha system of medicine has been evolved from a study of the special characteristics of the physical constitution of the people of south India not to speak of that portion consulting the Tamil continent which was submerged in the sea and the medicines prescribed in that Science are such herbs, pulps and roots peculiar to this country and in abundance and agreeable to the nature of the food suitable to their constitution and which the people are accustomed to.

The Indian customs and habits as well as the Indian climate are quite unsuitable to Allopathic Medicine as for instance, the use of several tinctures and spirits in every doses of medicine, means a great strain on the liver and the kidney; and this may in itself lead to various diseases. The several millions of south Indians were saved by our method for hundred of centuries and are still being saved in rural parts under Siddha system in spite of the modern introduction of Ayurveda and the Western system. The siddha system especially at the present day is fast dying out for want of encouragement and Research and many of the South Indian pharmaceutical factories formerly in existence in Mysore, Tanjore, Andra District etc., for supply of chemicals and drugs were all closed up owing to the passing of the poisons act by the British Govt.

Siddha works contain very useful informations that are absent in printed works. The whole work must be thoroughly analyzed with a view to enunciate the scientific principles underlying the system. The growing younger generations do not seem to show any interest towards ancient science of Siddhars simply because, the humanitarian side of Indian intellectual life, has of late, received materialistic baptism under the influence of Western culture and civilization producing at the same time, the inevitable result of natural contempt for out literatures, science, art and culture. The real cause of retrogression of the Indian systems as a whole is to be found in the callous indifference of the State towards them.

Firstly our Siddha theories have stood and survived the test of hundred of centuries, and so we are opinion that it cannot be rejected as in the case of theories of other systems, by modern scientists, excepts the theory of Karmic diseases which is far away from the reach of the Western science. In order to produce the desired effect medicines should be prepared in strict accordance with rules laid down in Tamil works. We generally follow the preparations adopted by our forefathers or our Gurus in Tamil works. So, individual merit and scholarship has to be recognized and handled over from Guru to his disciple.
