Out of stock
Duboisia myoporoides is a member of the Solanaceae family, native to eastern Australia, Papua New Guinea and New Caledonia. It is reported that Aboriginals used this species as a narcotic. Holes were made in the trunk of the tree and filled with water. The following day, the liquid was drunk, producing a stupor. The leaves contain scopolamine (hyoscine) and this species is grown commercially for extraction of this alkaloid for use in pharmaceuticals for sea-sickness and stomach ulcers.
Chemical variation is noted in Duboisia myoporoides, Nicotine being the major compound in plants from PNG, Anabasine from Central QLD and Scopolamine from Northern NSW.
