Antiseptic  Astringent  Carminative  Cholera  Diuretic  Dysentery  Expectorant  Parasiticide  
Poultice  Salve  Sedative  Stimulant  Vulnerary

A resin obtained from the trunk of the tree (see 'Uses notes' below) is antiseptic, carminative, diuretic, expectorant, parasiticide, poultice, salve, sedative, stimulant, vulnerary[21, 46, 57, 61, 149, 171, 213, 218, 222, 238]. It is chewed in the treatment of sore throats, coughs, asthma, cystitis, dysentery etc[222, 238, 257]. Externally, it is applied to sores, wounds, piles, ringworm, scabies etc[222, 238]. The resin is an ingredient of 'Friar's Balsam', a commercial preparation based on Styrax benzoin that is used to treat colds and skin problems[238]. The mildly astringent inner bark is used in the treatment of diarrhoea and childhood cholera[222].

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.

Adhesive  Gum  Incense  Parasiticide  Resin  Teeth  Wood

The aromatic resin 'Storax' is obtained from the trunk of this tree[46, 57, 61, 64]. It forms in cavities of the bark and also exudes naturally. It is harvested in autumn[181, 238]. Production can be stimulated by beating the trunk in the spring[171, 238]. The resin has a wide range of uses including medicinal, incense, perfumery, soap and as an adhesive[149]. It is also chewed and used as a tooth cleaner[183]. Wood - heavy, fairly hard, fine-grained, not strong, light, tough, resilient. It weighs about 37lb per cubic foot[227]. The wood takes a high polish and can be stained then used as a cherry, mahogany or walnut substitute[171]. It is also used for furniture, flooring, fruit dishes, veneer etc[46, 61, 82, 149, 227].

Cultivation details

Landscape Uses:Aggressive surface roots possible, Specimen, Street tree. Prefers a moist but not swampy loam in a sunny sheltered position[11, 200]. Succeeds in light shade[188]. Prefers a neutral to acid soil[130]. Plants grow poorly in shallow soils overlying chalk[188]. Young plants are susceptible to damage from late frosts. A highly ornamental plant, especially in its autumn foliage[1, 227], it grows well in Cornwall[59] and S. England but does not do well in the north[98]. A fast-growing and long lived tree, it is fairly free from pests and diseases and has the potential to be a re-afforestation tree in cutover lands[227]. Trees commence flowering when about 20 - 25 years old[229]. The leaves emit a balsam-like fragrance when they fall in the autumn, this is retained until the leaves are quite withered[245]. Plants in the north of their range do not produce much resin[183]. Resists honey fungus[88]. This species resents root disturbance, young plants should be pot-grown and be placed in their permanent positions as soon as possible[200]. Special Features:Attractive foliage, North American native, Invasive, Naturalizing, Inconspicuous flowers or blooms. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is flat with shallow roots spreading near the soil surface [2-1].

Propagation

Seed - best sown as soon as it is ripe in the autumn in a cold frame. Harvest the seed capsules at the end of October or November, dry in a warm place and extract the seed by shaking the capsule. Stored seed requires 1 - 3 months stratification and sometimes takes 2 years to germinate. Sow it as early in the year as possible. Germination rates are often poor. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame or greenhouse for their first winter. Since they resent root disturbance, it is best to plant them out into their permanent positions in early summer of their second year and give them some protection from cold for their first winter outdoors[K]. Cuttings of half-ripe wood, July/August in a frame. Suckers in early spring. Layering in October/November. Takes 12 months.

Observed (I presume stryaciflua) growing in happy profusion alongside a busy bac-road in Copeland NW Cumbria. apparently indifferent to the exhaust fumes and the erratic climate (boing charitable to my county!)

I am working with the German development cooperation in a forest program in Honduras. Anyone can help us with information on Styrax production?
