We follow the ancient concept of medicine and very particularly the extraction process.
The Siddha system of medicine sees the individual as a microcosm of the universe, which is made up of the five natural elements: earth, fire, air, water and space; and three humours: vatham(movement), pitham (digestion or metabolism) and kapham. Earth, Water, Fire, Air and Space the Pancheekaranam theory (Five Fold Combination) of Siddha science explains the origin and formation of these basic elements as well as the role of these five elements in the formation of every substance both in the universe and in human.
The food we consume is the fuel for the human body which is processed by the three humours, and when this equilibrium isn't maintained by the body, there is illness.
The basic concept of Siddha is similar to Ayurveda, although the differences begin to show when studied in detail, as the Siddha branch of medicine has its uniqueness and tradition rooted in Tamil philosophy and culture.
The basic concept of Siddha remains a system that puts equal emphasis on the mind, body and spirit. It works towards restoring this equilibrium of the individual. According to Siddha medicine, the route to a healthy soul is through a healthy body.
