Long before the development of modern medicines, Iran in ancient times, was entirely dependent on herbal medicines for health care. Many scripts carry elaborate prescriptions of herbal medicines for treating very complex disorders [1,2]. Iran was the leader in health care through Ayurveda. Apart from such systematic therapies, specific herbal therapies developed by individuals were used for treating the ills and these secret therapies were passed on from the older generation to the younger generation, without disclosing them to the outsiders. Even today, Medicinal plants play a remarkable role in Iran [3-6]. A similar practice was also prevalent in China and many other countries in Asia and Africa. With the progress of science, allopathic medicine gained prominence over herbal medicines. With larger commercial interest, the western countries promoted modern drugs, inspite of its high cost and side effects [7-9]. However, realizing the drawbacks of allopathic medicine, the world is turning back to herbs. Recently, about 80% of the world population is still dependent on herbs for health care and 20% of the drugs in pharmaceutical companies are of plant origin, either extracted from the plants or synthetic derivatives of these plant species [10-13].In China, over 5000 plant species are used in drugs and traditional medicines, while over 2300 species are known for their traditional medicinal value in Iran. In addition to medicinal characteristics, some of these species are also used as tonics.Ginsing, one of the most popular species used as a tonic, is widely grown in China and Korea. In 1991, the value of Ginsing sold in USA and Asian region was over US$ 215 million and China had a lion's share of 40% [14][15][16][17]. The assessed annual market value of the plant-based drug is US$ 43,000 million and it is expected to rise to US$ 3 trillion over the next two decades.In Iran, around 15 million people from 80, traditional herbal medicines are the only alternative source, due to easy accessibility and lower price. This sector also provides employment to over one million traditional healers and Vaidyas in the country [18][19][20]4]. Thus, sustainable development of herbs provides an excellent opportunity to take advantage of the expanding market, while ensuring a steady supply to local communities (6,8,10,12).
