Piturie

Pituri, also known as mingkulpa or bush tobacco, is a mixture of leaves and wood ash traditionally chewed as a stimulant by Aboriginal Australians widely across the continent. Leaves are gathered from any of several species of native tobacco (Nicotiana) or from at least one distinct population of the species Duboisia hopwoodii. Various species of Acacia, Grevillea and Eucalyptus are burned to produce the ash. The terms pituri and mingkulpa may also refer to the plants from which the leaves are gathered or from which the ash is made. Some authors use the term pituri to refer only to the plant Duboisia hopwoodii and its leaves and any chewing mixture containing its leaves.
