Duboisia myoporoides, or Corkwood, is a shrub or tree native to high-rainfall areas on the margins of rainforest in eastern Australia. It has a thick and corky bark. The leaves are obovate to elliptic in shape, 4–15 cm long and 1–4 cm wide. The small white flowers are produced in clusters. This is followed by globose purple-black berries (not edible).
The leaves are a commercial source of pharmaceutically useful alkaloids. The same alkaloids render all plant parts poisonous. The leaves contain a number of alkaloids, including hyoscine (scopolamine), used for treating motion sickness, stomach disorders, and the side effects of cancer therapy.
