There are 6 major, 21 medium and 37 minor markets of medicinal plants spread across the country. A major market is taken to be one that has more than 25 big traders of medicinal plants with an individual turnover of Rs. 5 million or more per annum; a medium market is one where there are 25 to 50 big traders whose turnover ranges between Rs. 2.5 to 5 million per annum; the rest of the centres with smaller numbers of big, exclusive traders and lower turnover are classified as minor markets. The minor markets also include centres that have a greater volume of trade but where only a few species are traded, like Dhamtari in Madhya Pradesh where a few species such as Aloevera,Aonla, Harra and Beheda are traded in huge volumes. The major centres, located at the heads of the routes taken by the medicinal plants, are big cities, including the metros. Centres like Anand, Ahemadabad, Rajkot, Jaipur, Udaypur, Lucknow, Kanpur,Gorkhpur, Patna, Ranchi, Ujjain, Bhopal, Satna, Hyd-erabad Sidhpur, Unjha, and Siliguri are specifically medicinal plants markets. Major export takes place from Delhi, Mumbai, Chennai and Tuticorin. The supply channel runs from the minor to the medium to the major markets before being exported.
