J Gill Go-by-the Ground J glecoma hederacea Lin. Sp. Pl. 807; is a low, hairy, creeping plant, with square stalks; roundish or kidney-shaped leaves, set in pairs at the joints; the flowers are bluish and labiated; the upper lip is cloven and turned backwards. It is common in hedges and shady places; flowers in April, and the succeeding warm months; is generally greenish all the winter.

This herb has a quick, bitterish, warm taste; an aromatic, but not very agreeable, smell, in a great measure dissipated by drying. It is supposed to be useful in disorders of the breast, and as an attenuant. In obstinate coughs it is a favourite medicine with the poor, given in the form of tea, sweetened with honey; and Dr. Pit-cairn speaks highly of it in consumptions. Dr. Cullen found no evidence of its diuretic or pectoral effects, and thinks it very improbable that it should be useful in phthisis. Ale is rendered very fine by an infusion of ground ivy, and called gill-ale. It yields its virtue most perfectly to water by infusion, and, on inspissating the filtered liquor, only the unpleasant smell is lost. See Lewis's Materia Medica.
