Action: Seeds are used for treating coryza with thin excoriating discharge with lacrimation, sneezing and hacking cough, nostril blockage and dry and hot feeling of pharyngitis.

The seeds contain glucosinolate sin- igrin, which produces allyl isothio- cyanate when mixed with warm water. Allyl isothiocynate acts as a counterir- ritant when diluted (1:50).

Morus Nigra

Linn.

Family: Moraceae.

Habitat: Native to West Asia; cultivated in Kashmir, also grown in Darjeeling.

English: Black Mulberry.

Unani: Tuut Siyaah.

Action: Berries and root bark— mild laxative and used in the treatment of respiratory catarrh. Berries—refrigerant, given during convalescence.

The fruit contains invert sugar, pectin, fruit acids (including malic and citric acid), ascorbic acid, and fla- vonoids (including rutin). Leaves contain flavonoids, including rutin (26%). Root bark contains calcium malate; the bark of branches contains tannins, phlobaphenes, a sugar, a phy- tosterol, ceryl alcohol, fatty acids and phosphoric acid.

An infusion of leaves causes a drop in blood sugar, sometimes diuresis and a reduction in arterial pressure. It shows no effect on glucosuria.

Morus acidosa Griff., M. australis Poir and Morus indica L. have also been equated with Tuut Siyaah of Unani medicine.... morus nigra

Populus Nigra

Linn. var. italica Kochne.

Family: Salicaceae.

Habitat: North-western Himalaya at 900-3,700 m.

English: Black Lombardy Poplar.

Action: Bark and balsam from leaf bud— used for cold. Bark— depurative. Leaf bud—antiseptic, anti- inflammatory.

The bud exudate contains dimethyl- caffeic acid, which was found active against herpes simplex virus type 1.

A 50% ethanol extract of a mixture of flowers and buds showed 11% inhibition of enzymatic conversion of testosterone into 5 alpha-dihydrotesterone and 4-androstene-3,17-dione. The extract was partitioned between ethylac- etate and water and the resultant ethy- lacetate fraction contained the active compounds, pinobanksin, demethyl- quercetin and pinocembrin. It exhibited 15% inhibitory activity on the enzyme. Pinocembrin was the most potent, almost equal to estradiol, which was used as a control.

The bark of all Populus species contains, phenolic glycosides, salicin and populin (salicinbenzoate). Tannins are also present (5-9%).

Both salicin and populin cause elimination of uric acid. Salicin is antiperi- odic and is used like quinine in intermittent fever, also in coryza, rheumatism and neuralgia.... populus nigra

Action: Analgesic, antiinflammatory, febrifuge. Used for rheumatic inflammation, painful muscles, spondylitis, lumbago, sciatica, neuralgia, gout and fever. (In 1838, chemists identified salicylic acid in the bark. Afterwards, synthesized it as acetylsalicylic acid, aspirin, in 1899.)

The British Herbal Compendium additionally reported analgesic, antipyretic, antirheumatic and astringent actions of the willow bark.

The bark contains phenolic glyco- sides; salicin, picein and triandrin with esters of salicylic acid and salicyl alcohol, acetylated salicin, salicortin and salireposide; tannins; catechin; p- coumaric acid; flavonoids and polysac- charides.
