Malva Pharm. Lond. & Edinb. Malva silvestris folio sinuato C. B. Malva sylvestris Linn. Common mallow: a plant with firm branched stalks, and roundish, notched leaves, set alternately on long pedicles: in their bosoms come forth bell-shaped monopetalous flowers, deeply divided into five heart-shaped sections, of a pale purplish or whitish colour variegated with deeper streaks, followed by a number of cap-sules set in form of a flat disk and containing each a kidney-shaped seed: the root is long, slender, and whitish. It is perennial, common in uncultivated grounds, and found in flower throughout the summer.
The leaves and flowers of the mallow are in taste mucilaginous, and of no remarkable smell. The leaves were formerly of some esteem, as an emollient or laxative dietetic article, in dry constipated habits in the warmer climates: at present,, infusions or decoctions of the leaves and flowers, and a conserve made by beating the fresh flowers with thrice their weight of fine sugar, are sometimes directed in dyfuries, heat and sharpness of urine, and other like complaints; but the principal use of the herb is in emollient glysters, cataplasms, and fomentations. The roots have been recommended in disorders of the bread, and though now disregarded, may perhaps deserve some notice: they have a soft sweet taste, without any particular flavour, approaching in some degree to that of liquorice: an extract made from them by rectified spirit of wine is of great sweetness.
