Why aged cheese can matter with ayahuasca
Aged cheese can contain tyramine, a substance formed as proteins break down during aging and fermentation. Normally, enzymes in the gut and liver—especially monoamine oxidase—help dismantle tyramine before much of it reaches the bloodstream.
Ayahuasca contains harmala compounds that temporarily inhibit monoamine oxidase. With that cleanup system partly blocked, tyramine may have a stronger effect: it can prompt nerve cells to release noradrenaline, a chemical that tightens blood vessels and raises blood pressure.
From food interaction to medical danger
A sharp rise in blood pressure can cause severe symptoms and, in extreme cases, life-threatening complications. The danger is not that cheese itself is poisonous, or that every serving will trigger a crisis. Tyramine levels vary among foods, and the strength of the interaction depends on factors including the amount consumed and a person’s health and medications.
The practical point is that ayahuasca’s effects are not limited to its psychoactive experience. Because its compounds can interfere with the body’s handling of other substances, combining it with tyramine-rich foods or certain medicines may create risks that are difficult to predict. A food that is ordinary on its own can become part of a hazardous combination when the body’s usual chemical safeguards are temporarily inhibited.
