I set off to try and answer this question after one of my patients whom I saw at my Bradenton clinic brought along an article that claimed that "nettle leaf lowers creatinine level in the blood". This by extension would mean that it could perhaps cure CKD? I was quick to admit that not once during my typical "western medicine" training had I heard of that claim. To me, CKD had always been this inexorable malady that can be, at best, controlled or slowed down from progressing further. "Cure" is not a word that gets thrown around a lot when you talk about CKD. As I had discussed earlier, once kidney function declines chronically, it can typically not be regained.
But I do try to have an open mind, the good old scientific temper and all that. So rather than dousing disdain over my patient's excitement, I tried to look for evidence to see if the article's claim was indeed true.
