Nu-nu
From Wikipedia, the free encyclopedia
Nu-nu is a herbal stimulant used by the Matsés people of the Amazon to prepare men for a successful hunt.[1][2]
To prepare the snuff, the powdered roasted leaves of mapacho (Nicotiana rustica) are mixed with alkaline ashes of the inner bark of the mocambo tree (Theobroma bicolor), which, in the proper amount, improves the absorption of the drug while lessening the nasal irritation. The leaves and alkali are ground into a very fine powder and mixed.
