Gratiole (Gratiola officinalis), sometimes nicknamed "poor man's herb" in certain corners of rural Europe, was once regarded with particular caution by the old herbalists. Growing in damp meadows and ditches, this unassuming plant long occupied an ambiguous place between remedy and feared poison. Its traditional use, largely abandoned today, belongs above all to the history of folk pharmacopoeia.
Gratiole was once used as a powerful purgative in rural Europe, reserved for occasional, carefully supervised use because of its potency.
The old herbalists credited it with diuretic properties, used very sparingly to relieve excess water in the body.
Some old country notebooks mention a traditional veterinary use of the plant, particularly for livestock, though this practice remains poorly documented.
Although a few old sources mention its use in children against certain intestinal worms, this use is now considered dangerous and has been abandoned by serious herbal tradition.
Toxic at an unsuitable dose: never self-administer gratiole without the advice of a qualified professional. Strictly discouraged for pregnant or breastfeeding women because of known risks. Contraindicated in children, despite some historical mentions to the contrary, because of its digestive toxicity. Medical consultation is essential before any use, as the margin between an active and a toxic dose is very narrow.
