i was gonna try echinacea for something or other i heard it was good for ... cannot remember what it was now ... but anyways ... then i read it is not recommended for those with high bp or was it those with arthritis ... lol i do not know now but it wasn't one recommended for me LOL, so i never ended up takin it... my case in point is even if it is a supplement or vitamin type of thing, always check if you should take it, in regards to other conditions you may have or other meds you may be taking. some are great - others can cause problems more than help, depending on you and your condition.
