Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.

The leaves are a bitter, hypnotic herb that dilates the pupils, stimulates respiration and acts as a sedative[238 ]. It contains duboisine, a mydriatic alkaloid[46 ]. The leaves contain various alkaloids and have been used to make intoxicating drinks[46 , 694 ]. The plant is a rich source of tropane alkaloids[317 ]. These alkaloids are used in the pharmaceutical industry for the production of a wide range of medicines including stimulants, antispasmodics and analgesics. The leaves are used in homeopathy for the treatment of eye complaints[238 ]. The herb is subject to legal restrictions in some countries[238 ]. Duboisia is probably the most important of the Australian native medicinal plants. The leaves are a valuable source of the alkaloid drugs, scopolamine and hyoscyamine. Cribb (1981).

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

Industrial Crop: Medicinal  Industrial Crop: Pesticide  Management: Standard  Regional Crop

A plant of the moist tropics and subtropics, where it is found at elevations up to 1,000 metres. It grows best in areas where annual daytime temperatures are within the range 20 - 30°c, but can tolerate 10 - 36°c[418 ]. Plants can tolerate some frost[694 ]. It prefers a mean annual rainfall in the range 1,000 - 2,000mm, but tolerates 600 - 2,500mm[418 ]. Prefers a light, well-drained soil and a sunny position[238 ]. Prefers a pH in the range 5 - 6.5, tolerating 4.5 - 7[418 ]. Plants can flower virtually all year round[694 ]. The plant has a suckering habit, especially after fires, and has the potential of becoming a weed[418 ].

Carbon Farming

  • Industrial Crop: Medicinal  Most pharmaceuticals are synthesized from petroleum but 25% of modern medicines are based on plants.
  • Industrial Crop: Pesticide  Many plants provide natural pesticides.
  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
