I have around 800 sq. mtrs. of agricultural land which I had bought some 10 years back at dirt cheap price. The price of the land has not increased much since it is an agricultural land. So I am thinking of cultivating medicinal plants, and if possible export them. Some friends have suggested that I take up cultivation of Stevia, which is used to manufacture natural sweetener, which can replace sugar for diabetics. Other one they have suggested is aloe vera, which has lot of demand in cosmetic industry. Can anyone offer any other suggestions?
