Who was Serita (Thrita) ?

The first doctor in the Ancient Persia Iran Tryth (Thrita) Garshasp Pahlavi’s father, the man who has healing the disease and death and Zoroastrians believed the treated way of him. However it is said that the first person who has been treating patients’ Tryth (Serita)

Aryans and Indians who knew him well and follow his orders.

The origin of medicine in Central Asia is directly connected with the medicine of Ancient Ariana. So called Mazdayasnian or Zoroastrian medicine has become its later development.
Main traces of the Ancient Arianian medicine can be found in the great range of the Avestan (Yasht 3, Videvdat, Husparam, Nikadum, Chithradat) and Pahlavi Zoroastrian writings (Bundahishn, Vizidagiha i Zadspram, Shkand-gumanig-vizar, Drakht i asurig ud buz, and so on).
Of course, it exerted vast influence upon the formation and growth of the Central Asian medicine in the Islamic period.

Thereupon we try to make parallel between the two great physicians of Central Asia – between Avicenna (Ibn Sina), who is the symbol and luminary of the Islamic era, and Thrita, who according to the Zoroastrian tradition was the first physician of the Ancient Ariana and has invented first antidotes and remedies.
He also has introduced the main methods of medical treatment, including the use of surgical knife and performing operations. Historical and mythological role of Thrita is widely observed in the paper, as well as the origin of diseases, as it is presented in the Avestan and Pahlavi literature.
Every disease or malady is originated against Ahura-Mazda by his evil adersary Angra-Mainyu in form of poisonous essence from the name of which has derived the medical formula first invented by Thrita (vishchithra, i.d. vish – “poison”, chithra – “seed; origin”) that was the earliest mentioned isotherapic remedy. Diseases have spread with the counter-work of the evil forces – reptiles and vermins.
