Sorry for my sarcasm but the one-liner was sooooo powerful without any detailing what it is about. Thank you for being more specific now, you've brought no link but the thread was easy to find.
From this very thread:

From the other thread you refer too:
tango wrote:...Finally, mushrooms became part of this journey some time around year 3, and have been a trusted companion ever since.
But here not one word that mushies caused a form of healing, only being a "companion". So the story how the mushies became healers is not brought forth so far
