Heart/Cardiovascular Conditions

If you have any high blood pressure or cardiovascular heart conditions it is not recommended to participate in ceremonies. Ayahuasca can elevate the blood pressure and increase heart attack risks. People with such conditions should not attend Ayahuasca ceremonies but take other natural medicines to help with their conditions.



People with diabetes have more risk involved with the absorption of Ayahuasca. The use of the MAOIs present in Ayahuasca can alter blood sugar levels via hypoglycemic effects. MAOIs may change the amount of insulin or oral antidiabetic medication that is needed by your body. People with severe unstable diabetes should not take Ayahuasca because of this risk. People with less severe diabetes should contact us prior to booking a retreat to discuss the particulars of the case including the possibility of a modified dieta.
