I've been wanting to ask this question for a while. I attended ayahausca ceremonies with don Jose Campos in March of 2008. He used what I believe to be a traditional rattle made of dried leaves called a chacapa. At one point during the ceremony, Don Jose walked around the lodge rattling the chacapa and singing his icaro. As he came to each person, he fanned them with the chacapa and bopped them on the head with it a few times. There seemed to be a fantastic aroma coming from the chacapa, that seemed to deepen the visions incredibly! My question is does this aroma come naturally from the leaves in the chacapa, or is something added to it to create this amazing smell? What kind of leaves are chacapas made from? I'd be interested in hearing of other experiences with the chacapa.
