Duboisia myoporoides, commonly known as corkwood or pituri, is a small tree or shrub native to Australia. It belongs to the Solanaceae family and is renowned for its medicinal properties. The plant features smooth bark and glossy green, oval-shaped leaves with pointed tips. It produces small white flowers, followed by green berries that turn black when ripe.
The leaves of Duboisia myoporoides contain alkaloids such as hyoscyamine and scopolamine, which indigenous Australians have used for centuries for medicinal purposes, including pain relief, sedation, and treatment of respiratory conditions.
In the pharmaceutical industry, the plant has been utilized to produce drugs such as atropine, which is used to treat bradycardia (slow heart rate) and other heart conditions.
Duboisia myoporoides thrives in well-drained soils and can grow in either full sun or partial shade. It can be propagated from seeds or cuttings but requires regular pruning to maintain its shape.
While Duboisia myoporoides offers many benefits, it can be toxic if consumed in large quantities. Therefore, it should only be used under medical supervision by trained professionals who understand its potential risks and benefits.
The corkwood tree is fairly disease-resistant and typically not susceptible to illnesses. Regarding care, this plant is fairly low-maintenance. When grown outdoors it needs only light watering, and larger specimens usually do not require pruning. Smaller plants, however, should be trimmed after they finish blooming. The corkwood tree is well-suited for anyone with an outdoor area, such as a garden or a deck, and does not demand extensive care experience.

Pruning
The corkwood tree is an evergreen plant celebrated for its height and fragrant white flowers. To maintain its health and encourage abundant flowering, it is important to prune the tree in early spring.
