According to the Siddha system of traditional medicine (Tamil: சித்த மருத்துவம், citta maruttuvam) of ancient India, the human body is composed of 96 tattvas (also thathuvas)[1] or basic principles.
[citation needed] A central concept to samkhya and other Hindu philosophies is the five primordial elements or pancha boothas i.e., earth (solid), water (fluid), fire (radiance), air (gas) and space (akasam).
[4] All the matter (both created and evolved) including animal, plants or mineral comes under these five primordial elements.
[5] The Siddhas also believed that the human anatomy and physiology, the factors causing disease, the materials used for the treatment and to cure the disease, and food consumed by the living organisms – all of these fall within the five primordial categories.
[8] Next to the Tatwas the human body exists of 72000 blood vessels, 13000 nerves and ten main arteries.
