I am taking Japanese knotweed for lyme disease but read on selfhealth.com that long term usage can be toxic to kidneys. Are you able to comment on this for me please?
I have not heard of that problem and I did check the literature pretty carefully, especially the Chinese who use the herb extensively. I tried your link and everything was in German which I don’t read, so cannot respond to that.
Dear Mr Buhner
Thousand thanks from France.
Best regards
