1 Suggestion I would make is that many Muslims make extraordinary amounts of money while selling dates, Olive Oil, Black Seed oil, Honey etc.
Excellent qualities of organic products can be cheaply bought on the Internet for less then half of what is offered by many Muslims. For example Organic Nigella Sativa from (German Amazon) is 10% the price of Muslim version which has "Sunnah" written on it with no quality controls etc.
You have raised a very important point but I found this in the study to be interesting.
So I guess we would need to know how the oil is extracted for it to be of maximum benefit according to this study
This cannot be undone and I am sure it will be greatly appreciated.
