Medicinal Mushrooms and Mold Toxicity

I have found very little about this online, so I'm reaching out to the sub-community of the mycotoxin-aware.

Is there a risk of mycotoxin exposure or cross-reactivity when a person with mycotoxin illness takes medicinal mushroom extracts? I'm talking about lion's mane, cordyceps, reishi....

Buhner says those who fear yeast/fungal explosions due to mushrooms have nothing to worry about. He did say leave out mushrooms if you have fungal hypersensitivity.
I took Cordyceps early in treatment and my chemical sensitivities flared, so I dropped it and never took it again. I was taking very expensive powder, not the tincture.
I do take lion’s mane tincture and have never noticed any adverse reactions or herxing with it. I only take 1/2 dropper, though.
You won’t know unless you try. I would love to try Cordyceps again.

I used to eat mushrooms regularly until I was dx with CIRS. I have eaten them on isolated occasions since and have never had any reaction to eating mushrooms.
