Ergot alkaloids bind with alpha-adrenoreceptors and evoke an inhibition of beta-adrenoreceptors = vasoconstriction, contraction of the uterus, inhibition of prolactin secretion The fusarium mycotoxin zearalenone increases membrane permeability, and promotes uterine synthesis

Molds secrete over 400 different mycotoxins, all of which are toxic to all humans. Everyone in a mycotoxin contaminated environment will have fatigue and other systemic symptoms, but may write them off to other causes. Fatigue from mycotoxin exposure indicates multisystem systemic toxicity. Even individuals with no exaggerated immune response to fungal/mold/yeast antigens, and therefore showing no major acute symptoms, are being slowly poisoned every minute spent in a mold contaminated environment.
