Also known as white mallow.
Marshmallow is native to Europe, temperate Asia and North Africa. It typically grows in wet wasteland, seaside or salt meadows. It is a protected plant in some regions. Originally, the confectionery of the same name – which already existed in ancient Egypt – was produced from the mucilage extracted from its roots; today it is more frequently made with collagen of animal origin. Its scientific name, Althaea, is that of a queen known for her healing talents in Greek mythology.
The marshmallow root has antitussive properties: it contains mucilages, which release a viscous substance, with a softening and emollient effect, which soothes greasy or dry coughs. It calms sore throats by acting on irritated or inflamed mucous membranes and is useful in cases of bronchitis, laryngitis, pharyngitis, tracheitis and asthma.
Decoction: 10 grams of peeled roots per litre of water, possibly with verbena or sage in case of flu. Bring to the boil, boil for 10 minutes and then filter. Drink up to 3 cups per day.
In case of persistent symptoms or if you have any doubts, consult a doctor.
