Medicinal Uses

"In Wales, Herb Robert was used as a remedy for gout, and it is recorded as a diabetes remedy in Ireland (Ô Súilleabháin) – a handful of the herb to a pint of water, in wineglassful doses, night and morning (Moloney). Culpeper says that it will heal wounds and stay blood. This sounds like doctrine of signatures, for the whole plant has a red look about it, particularly the stems and the fading leaves. In the same way, it was used in Scotland for erysipelas, or “rose”. Scarlet cloth was also used (Gregor). But the medicinal use went beyond this, and still is used, by herbalists, to treat any skin eruption, herpes, etc., (Schauenberg & Paris), even skin cancer (Beith)." [DPL Watts]
