Thanks for sharing the link of the oil you use and great article, but there is only one thing that is misconception and that I see everywhere and that drive me crazy, I like when thing are call properly for what they are and most people that supposedly expert! Are still repeat that misconception instead of telling people the truth.. Black seed is Sativa Nigella and Black cumin are a total different species that doesn't have the same propriety, and this is a fact. Please don't say black seed is black cumin seed, it's not true. but for the rest thanks.
There are two types of cumin seeds, called jeera. There is the common cumin seed (cuminum cyminum), and then there is a darker, smaller one called kala jeera (bunium bulbocastanum) or black cumin.
Neither ďcuminĒ nor ďblack cuminĒ is black seed. Black cumin IS NOT black seed and although plenty of products now erroneously label themselves as black cumin, the two should not be confused. Black cumin is actually from the plant bunium bulbocastanum, which is in the Apiaceae family. Black seed, which the sought after oil is made from, is actually nigella sativa and not related to cumin at all.
Black seed oil, nigella sativa, comes from the beautiful Love-in Mist flower. In Indian cooking the seeds are called kalonji.
