few educate Indians to this system of medicine. Today various charitable organizations colleges throughout the country promote this form of medicine.
This ancient medical tradition, with its origin in the Mediterranean world was developed in the Middle East. It was brought to India with the spread of Islamic civilization around the 10th century A.D. the Unani system of medicine was founded on the principles propounded by Galen, a Greek practitioner. Abu Sina, an Arab philosopher and physicist, also known as Avicenna in English (A.D. 980 - 103), was instrumental in the development of this system of medicine.
Many other Arab and Persian philosophers also contributed to its growth and development. The role in the development of Unani is evident from the fact that this style of medicine is now not known as Gaelic, as it was earlier called, but the Unani (Arabic name for Greek) system of medication.
Unani system of medicine revolves around the fact that food is transformed by the natural warmth in the stomach into different substances. A part of these substances that are useful to the body are transported by the blood to different organs, while the waste is excreted. The main products of this process according to the Unani system were the four cardinal humours:
Blood
Mucus
Yellow bile
Black bile
These humours were combined with the four
primary qualities
Warmth (or heat)
Cold
Moisture (or damp)
Dryness
This system of medicine states that if the four humours and the four primary qualities are all in a state of mutual equilibrium, man is healthy. It is the influence of external factors such as climate, age, profession and the customs that causes a dominance of one of the four humours observed in every human body. Both rules and noblemen from t eh beginning of the Muslim rule, built hospitals that followed the Unani system. During the reign of Akbar, there was a mass exodus of learned men from regions where Arabian medicine was taught.
