A common misconception about these so-called "dietary supplements" is that people have a tendency to say, "Oh, why not try it, it can't hurt." Of course, without clinical trials, any benefit is subjective and anecdotal. But the real problem is that often it CAN hurt. Testing has shown that 20% of dietary supplements from India have heavy metals like mercury in them! These manufacturers - unlike the pharmeceutical companies - have NO oversight or legal standards. Black cumin oil may not contain any black cumin at all! Until I have a list of ingredients and a reputable manufacturer I'm not gonna ingest that stuff. And that goes for any substance if I don't know what's in it.
