Maybe a misunderstanding by me? reading curezone a while back I got the impression that taking r ala without doing rounds of chelation would more than likely be detrimental so I put it away til reading more and then ..Got one of those info-overload moments, decide not to try. Cilantro tincture on occasions had helped but recently spent considerable time on job ( old car that hasn't moved in 20 yrs , large tree reclaiming it)! Now its moving but 2 weeks crawling around under it did its toll on my lower back, (L5 S1) I suppose I could give r ala a try, thanks
