market prices

Dear Friends, I am very much interested in medicinal herbs trading and want to get a kick start. Well till now, I am more into learning stage so I don't know much about market prices. So it will be of great help if someone can help me with recent market prices of raw medicinal herbs...

I would like some information on the market for vetiver roots in South India, the prices and whether commercial cultivation of vetiver is economically viable. Thank you.
