Rats were treated orally with ayahuasca (AYA) on gestation days (GD) 6-20 at doses corresponding to one-(1X) to eight-fold (8X) the average dose taken by a human adult in a religious ritual, and the pregnancy outcome evaluated on GD21. Rats treated with 4X and 8X doses died during the treatment period (44 and 52%), and those that survived showed kidney injury. Rats surviving the 8X dose showed...
