In the jungles of Brazil, we take Kambo the morning before Aya and at other times the morning after - both very good. There is no reason to not take Kambo before Aya. We leave 6 hours between the two. Done it 2-3 dozen times and always excellent. We run group ceremonies 20-30 people and we all take Aya the same night, then we take Kambo again the next day. Before Aya, its clears the way for a stunning night, afterwards, it clears anything you didn't release during the night. All good.
