II first found the Kidney Disease Foundation website when I was wondering if CKD is reversible. My primary care doctor ,an internal medicine doctor, says it is not reversible. I wanted to double check that just in case there have been new discoveries in kidney disease reseearch.
Then I saw an article at this site on the dangers of herbal supplements for people with kidney disease. I was concerned because I had just bought some herbal mushroom supplements and bee product supplement, to help control my sinus allergy symptoms. The herbs this site listed were not the herbs I have, but it got me thinking.
I looked up my mushroom supplements, and sure enough, chaga mushroom can damage the kidneys, including causing kidney failure. It has a high oxalate content, which forms crystals in the kidneys tubes that the kidneys can't dissolve or expel, thus damaging the cells of the tubes which causes scarring, and eventually the tubes are too scarred to work at all.
I am still looking for info on turkey tail mushrooms and their effect on kidneys. I haven't found any sites that weren't sponsored by supplement companies.
WebMD only had a small amount of info on their use in Japanese and Chinese medicine to help alleviate the symptoms of chemotherapy for cancer patients. No mention of toxicity for it in supplements. Next I will see if the National Institute of Health website has any information. I will also check to see if horehound tea, and regular black and green tea are toxic to kidneys, especially diseased kidneys.
