Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

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 plant is antibacterial, antiinflammatory, antifungal, antitussive, antiviral, astringent, blood purifier, cardiac, diaphoretic, digestive, diuretic, febrifuge, haemostatic, hypotensive, oxytocic, vulnerary[318 ]. The bark is a rich source of tannins and antioxidant chemicals called proanthocyanidins[318 ]. One in particular, procyanidin B-2, has been shown in various studies to help promote hair growth and alleviate baldness[318 ]. Other independent research indicates that procyanidin B-2 also has antitumor and anticancer effects (even against melanoma) as well as lowers blood pressure and protects the kidneys[318 ]. The bark also contains a chemical called kaurenoic acid which has been documented with antibacterial and antifungal properties in many studies over the years[318 ]. The leaves of mutamba contain caffeine, however none has been found in the bark of the tree[318 ]. Other studies have shown that the plant lowers heart rate and blood pressure, relaxes smooth muscles and stimulates the uterus[318 ]. Various studies using leaf and bark extracts have clinically demonstrated remarkable antibacterial activity against several disease-causing pathogens, including Bacillus, Staphylococcus, Streptococcus, E. coli, and Neisseria gonorrhea[318 ]. One of the recent 2003 studies also confirmed its antioxidant effects[318 ]. In a 1995 in vitro study, mutamba also demonstrated antiviral activity[318 ]. The bark is the part most used. It is used as to induce perspiration, as a tonic and a blood cleanser[318 ], and is employed to treat a wide range of disorders including; digestive tract problems such as gastrointestinal pain, liver problems, diarrhoea and dysentery; urinary and reproductive tract problems such as kidney problems, uterine pain, prostate problems, venereal disease and as an aid to childbirth; respiratory tract problems such as asthma, bronchitis, coughs and pneumonia; fevers and haemorrhages[318 ]. Applied externally, it is used to bathe wounds, rashes and sores; to treat skin problems, including dermatosis, elephantiasis and leprosy; it is applied to the scalp to arrest hair loss and combat parasites of the scalp[318 , 739 ]. The fruit (in Mauritius), the roasted seeds (in Java), and the bark (in India) are officinal remedies against elephantiasis)[317 ]. An infusion of the crushed, seed soaked in water, is used to treat diarrhoea, dysentery, colds, coughs and venereal diseases. It is also used as a diuretic and astringent[303 ].

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Other Uses

Agroforestry Uses: A natural pioneer species that colonizes recently disturbed areas, it is fast-growing, tolerant of full sunlight and provides food for the native fauna. It can be used as a pioneer species when restoring native woodland, but is best not used outside of its native range[325 , 419 ]. Other Uses The tough, fibrous bark and young stems are used to make rope and twine[303 , 419 ]. The mucilaginous sap is used sometimes in sugar fabrication to clarify syrup[301 , 317 ]. The heartwood is pinkish to brownish; it is not clearly demarcated from the light brown sapwood[303 ]. The texture is coarse; the grain is straight to interlocked; lustre is medium; there is no distinctive taste or aroma. The fibrous wood is light in weight; it is not durable, being very susceptible to attack by dry-wood termites. It is easy to work and finishes well. It is used for posts, interior carpentry, light construction, furniture, boxes and crates, shoe horns, tool handles etc[46 , 303 , 363 , 418 ]. The tree can be used for fuel and to make charcoal[303 , 325 ]. The charcoal is of high quality[419 ].

Cultivation details

Agroforestry Services: Living fence  Fodder: Bank  Fodder: Mast  Management: Coppice  Management: Standard  Regional Crop

A plant of the dry to moist tropics, where it is found at elevations up to 1,200 metres. It grows best in areas where annual daytime temperatures are within the range 22 - 32°c, but can tolerate 10 - 36°c[418 ]. It prefers a mean annual rainfall in the range 700 - 1,500mm, but tolerates 500 - 1,700mm[418 ]. The plant can tolerate up to 2,500mm annual rainfall[303 , 325 ]. Prefers a sunny position[303 , 325 ]. The plant is widely adapted, found growing in both alluvial and clay soils[303 ]. Succeeds on a variety of soils but is most common where pH is higher than 5.5[325 ]. Prefers a pH in the range 6 - 7, tolerating .5 - 7.5[418 ]. The plant can escape from cultivation and become a weed tree in areas outside its native range[418 ]. A fast-growing tree[419 ]. The tree can flower all year round in the more equatorial part of its range[325 ].

Carbon Farming

  • Agroforestry Services: Living fence  Simply managed rows of shrubs and trees.
  • Fodder: Bank  Fodder banks are plantings of high-quality fodder species. Their goal is to maintain healthy productive animals. They can be utilized all year, but are designed to bridge the forage scarcity of annual dry seasons. Fodder bank plants are usually trees or shrubs, and often legumes. The relatively deep roots of these woody perennials allow them to reach soil nutrients and moisture not available to grasses and herbaceous plants.
  • Fodder: Mast  Fruits and seeds of shrubs, woody vines, trees, cacti, and other non-herbaceous vegetation available for animal consumption.
  • Management: Coppice  Cut to the ground repeatedly - resprouting vigorously. Non-destructive management systems maintaining the soil organic carbon.
  • 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.

Propagation

Seed - requires scarification before planting[303 ]. Pour boiling water over the seeds, let them soak for 30 seconds and then drain[303 ]. With fresh seed, germination occurs in 7 - 14 days at a rate of 60 - 80%[303 ]. Seedlings are ready for out-planting when they reach a height of 30 - 40cm (about 15 weeks)[303 ]. The plant can also be established by direct seeding[303 ]. Cuttings[303 ].
