Ron Wheelock is the most productive ayahuasca cook in Iquitos.

The purge Ron prepares is not orthodox. Orthodoxy does not exist in ayahuasca shamanism. Although the best-known recipe for cooking the remedy is composed of the ayahuasca stems (Banisteriopsis caapi) and the chacruna leaves (Psychotria viridis), Ron uses other plants, processing them in a particular way. Ninety pounds of ayahuasca stems, preferably "sky". Ten pounds of huambisa leaves (Dyplopteris cabrerana, the DMT containing plant). Two hundred and fifty leaves of chiric sanago. Three ounces of mapacho tobacco. A handful of bobinsana flowers. And water: lots of water, forty gallons of water, which will be reduced by evaporation to seven or ten liters of the remedy.
