A special object, part of the Cohoba ritual, carved from bone and curved to fit down the throat to help the shaman purge himself. Vomiting accompanied large fasting to help the Cohoba to increase the effect. If inappropriate food was eaten, the shaman would not be able to travel and communicate with the spirits. Inhaling Cohoba powder produced visions that the Tainos interpreted as apparitions of spirits and messages from them. In the center of this vomiting stick a bat is represented. The bat symbolizes the upper world and figures the masculine gender in South American cosmology which form the basis for the Tainos magic religious beliefs.
