Any treatment should be considered a scam until proven effective.
Chinese medicine gets people to drink urine. A Shaman spits alcohol on people. A witch doctor conjures spells. None can be considered effective until proven effective.
"Proven effective" means. 1) Follows the reliable method, results are published 2) The experiment can be verified and replicated by anyone anywhere anytime.
That is the difference between the scientific method (So called "western medicine") and scams.
Summarizing: A fungus can be medicine, when proven effective. The older you state Chinese medicine is, the worse for its cause. So much time to show proof of effectiveness, so little they can prove.
