Before the cultivation of hops, this herb was widely used in Europe because of its bitter substances for preserving beer. Because of the bitter substances and essential oils, the plant was also used as a spice. The smell and taste is described as a resinous aromatic, minty and liquorice-like.

Essential oil of plants from Japan contained monoterpene-ketones like (-)-pinocamphone (spicy), (−)-menthone (minty), and (−)-pulegone (minty) as main components. \\

Germacrene D (15.6-18.8%) was the dominant compound in hydrodistilled oils (0.02-0.03%) of G.hederacea collected at full flowering in Lithuania. Other major constituents were γ-elemene (9.7-16.0%), β-elemene (9.8-11.1%), iso-phytol + phytol (4.7-15.6%), (Z)-β-ocimene (4.7-5.6%), germacrene B (2.9-3.9%), β-ylangene (2.7-3.9%), 1,8-cineole (1.9-3.5%). Minor components were α-cadinol (1.1-2.3%), (E,E)-α-farnesene (1.0-1.9%) and β-gurjunene (1.0-2.0%) eg. \\

The hydrodistilled essential oil (< 0.05%, v/w, on a dry weight basis) of aerial parts of Glechoma hederacea L. plants, which were transferred from five different natural habitats in Lithuania to the field collection, contained mainly germacrene D (5.5-15.5%), sabinene (6.3-12.3%), 1,8-cineole (5.1-41.6%), β-caryophyllene and caryophyllene oxide (7.3-19.3%,) and γ-elemene (9.6%). \\

The overground parts, collected during flowering were used for healing "pain of the hips", problems of the liver, and as diuretic. \\
