So! I have a friend who gets styes regularly. He drinks kava only once every week or two. He also takes cordyceps and is convinced they are the culprit. I also have a stye problem now. I think mine is from dehydration in general and wintertime. So I'm curious if anyone else takes cordyceps and whether they have heard of this problem? If you don't know what cordyceps is; it's popular for energy and boosting and regulating hormones, namely testosterone.
