Medicinal Part(s): Fresh or dried whole flowering plant, including the root.[PDR]


The whole herb, used fresh or dried;

Antioxidant: "The in vitro radical scavenging activities of the plant extracts [L. vulgaris, L. nummularia & L. punctata] were tested.... Our studies proved that L. nummularia extract had the most significant activity."[Toth et al.]

"Extracts of the aerial plant parts are said to be antibacterial in vitro..."[PDR]


"The main flavonoids in L. nummularia and L. vulgaris were identified as myricetin- and myricetin- quercetin-, and kaempferol-glyosides respectively". [Toth et al.][PDR]"The quantitative analytical measurements revealed that the total flavonoid content expressed in hyperoside of L. vulgaris was significantly lower than of the samples of L. nummularia, and L. punctata, but its hydroxycinnamic acid content was outstanding. The accumulation of polyphenols and tannins showed to be homogeneous among the samples."[Toth et al.]

"An easily grown plant, succeeding in a moist loamy soil[1]. Grows well in heavy clay soils. Grows well in marshy soil and in shallow water in pond margins[24, 56]. Prefers a shady position[111] but also succeeds in full sun[188]. Plants are hardy to at least -25°c[187]. Most species in this genus seem to be immune to the predations of rabbits[233]. A very ornamental plant[1]. Special Features:Attractive foliage, Invasive, Naturalizing, Fragrant flowers, Inconspicuous flowers or blooms."[PFAF]

Groundcover: "Can be used as a ground cover plant in moist soils but requires weeding for the first year or so. Plants should be spaced about 60cm apart each way and form a carpet, rooting as they spread[208]."[PFAF]


"Seed - sow spring or autumn in a cold frame[200]. This species rarely produces seed in Britain[17]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division in spring or autumn[200]. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring."[PFAF]
