Medicinal use of Black Mulberry:The mulberry has a long history of medicinal use in Chinese medicine, almost all parts of the plant are used in one way or another. The white mulberry (M. alba) is normally used, but this species has the same properties. Recent research has shown improvements in elephantiasis when treated with leaf extract injections and in tetanus following oral doses of the sap mixed with sugar. Analgesic, emollient, sedative. The leaves are antibacterial, astringent, diaphoretic, hypoglycaemic, odontalgic and ophthalmic. They are taken internally in the treatment of colds, influenza, eye infections and nosebleeds. The leaves are collected after the first frosts of autumn and can be used fresh but are generally dried. The stems are antirheumatic, diuretic, hypotensive and pectoral. A tincture of the bark is used to relieve toothache. The branches are harvested in late spring or early summer and are dried for later use. The fruit has a tonic effect on kidney energy. It is used in the treatment of urinary incontinence, tinnitus, premature greying of the hair and constipation in the elderly. Its main use in herbal medicine is as a colouring and flavouring in other medicines. The root bark is antitussive, diuretic, expectorant and hypotensive. It is used internally in the treatment of asthma, coughs, bronchitis, oedema, hypertension and diabetes. The roots are harvested in the winter and dried for later use. The bark is anthelmintic and purgative, it is used to expel tape worms. Extracts of the plant have antibacterial and fungicidal activity. A homeopathic remedy is made from the leaves. It is used in the treatment of diabetes.
Description of the plant:
Habitat of the herb:Original habitat is obscure.
Edible parts of Black Mulberry:Fruit - raw, cooked or used in preserves. A delicious slightly acid flavour, it makes an excellent dessert fruit and can be eaten in quantity. The fruit is juicy and refreshing, though it must be used as soon as it is ripe (from mid-August to September) otherwise it will start to rot. The fruit falls from the tree as soon as it is fully ripe. It is best, therefore, to grow the tree in short grass to cushion the fall of the fruit but to still make it possible to find and harvest. The fruit can also be dried and ground into a powder. The fruit is up to 25mm in diameter.
Other uses of the herb:A fibre used in weaving is obtained from the bark. A red-violet to dark purple dye is obtained from the fruit. A yellow-green dye is obtained from the leaves. Wood - used in joinery.
Propagation of Black Mulberry:The seed germinates best if given 2 - 3 months cold stratification. Sow the seed as soon as it is ripe if possible, otherwise in February in a cold frame. The seed usually germinates in the first spring, though it sometimes takes another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the cold frame for their first winter. Plant them out in late spring or early summer after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Plant out in spring. A good percentage take, though they sometimes fail to thrive. Cuttings of mature wood of the current season's growth, 25 - 30cm with a heel of 2 year old wood, autumn or early spring in a cold frame or a shady bed outside. Bury the cuttings to threequarters of their depth. It is said that cuttings of older wood up to 2.5 metres long can be readily made to strike. The cuttings are taken in February and planted 30cm deep in a shady sheltered position outdoors. The stem is wrapped in moss to prevent water loss by transpiration, with only the top few buds not being covered. Layering in autumn.
