I want to read all the responses but don't have time to do so right now. I will do it later. I do want to respond now. (Cart before the horse?)
My opinion: IF you have no reason to think it can cause harm and IF it's something you can afford, give it a try. I take turmeric every day and it helps me with a skin condition (undiagnosed professionally, probably psoriasis or eczema) and keeps my knees from hurting and being really stiff (maybe arthritis) and keeps my hands knitting. Other people say it doesn't help them, I don't care. It helps me. Hence my thought that if its unlikely to cause harm, give it a try.
You can't knit the left sock first. Ever.
