Winter savory is most often used as a culinary herb, but it also has marked medicinal benefits, especially upon the whole digestive system. The plant has a stronger action than the closely related summer savory, S. hortensis. The whole herb, and especially the flowering shoots, is mildly antiseptic, aromatic, carminative, digestive, mildly expectorant and stomachic. Taken internally, it is said to be a sovereign remedy for colic and a cure for flatulence, whilst it is also used to treat gastro-enteritis, cystitis, nausea, diarrhoea, bronchial congestion, sore throat and menstrual disorders. It should not be prescribed for pregnant women. A sprig of the plant, rubbed onto bee or wasp stings, brings instant relief. The plant is harvested in the summer when in flower and can be used fresh or dried. The essential oil forms an ingredient in lotions for the scalp in cases of incipient baldness. An ointment made from the plant is used externally to relieve arthritic joints. Source: https://pfaf.org/
