Go buy Nigella Sativa, or black cumin or habba al baraka. That is enough. Don't buy black carraway or nutmeg or onion or anything strange you are not aware of. It is simple go with the links and pick one. Mountain rose has real good bulk herbs but out of stock of the oils. Sunnah has the oils or Al Yusra.
Sometimes we try to make things too difficult. Think of this as a Indian version of black seed. The best black seed is from arab countries not from India. But shipping and everything is difficult. YOu want the best blackseed and reasonable go to http://www.elcaptain.com
. Sorry I did not understand you were trying to buy from indian store.
It is so confusing for people when they read these articles about onion, nutmeg, and caraway. That is why I try to keep it simple. I would not be buying from some out of the way store for a cheap price. Read my articles on cheap oils. Now if you are in India go there. If you are in America or Europe go to a Arab grocery store or order on the net. Do not trust anyone who tells you the seeds is ready for consumption. It most likely is too dang hot. They need to be hot. Oils, need to be in very dark bottles, just bought some from the Egypt site I gave you.
Remember oils, one hour before food mixed with juices.
