Tarahhom Behzad said 14 natural climates have been identified in the world, 11 of which exist in Iran and are the ground for the growth of various species of medicinal herbs.
About 8,600 species of the herbs have so far been identified in Iran, 2,300 of which have medicinal traits and are directly applied in medicine, health and food supplements, he added, Mehr news agency reported.
