Here I want to clarify that, I listen many stories regarding black turmeric. But I can say that these are baseless. It is simply a medicinal plant like sarpagandha, ashwagandha, brahmi, tulsi, aloe vera. But is a rare plant. Please do not get cheated by these storytellers. No such materials will be available to you. Please contact me for details about this plant. I am cultivating this plant since last 4 years. It belong to Zingiberaceae Family and curcuma Genus( other members of this Genus are curcuma longa, curcuma aromatica, curcuma amda etc.). So please be awared and save yourself from these cheaters. Its price is Rs500 to Rs600 per kg. Another thing, although it is called black turmeric, its colour is deep blue ( colour of fresh rhizomes). So contact me for details .............
