Marshmallow root (Althaea officinalis)
What it is
Contains mucilage that forms a soothing, protective coating over irritated mucous membranes in the throat, oesophagus, and stomach. Traditional use for coughs, sore throats, and acid reflux spans centuries, but almost no modern clinical trials exist. EMA classifies it as a traditional herbal medicine for mild digestive complaints and dry coughs. Very safe and well tolerated. Take 30 minutes away from medications as it may slow absorption.
Dose
500–1,500 mg/day root extract or 2–5 g root as tea; take 30 min away from medications
Time of day & tips
Take 30 min away from medications or food (the mucilage can slow absorption of other substances). Brew as a cold-water tea for soothing effect. Use 1–3× daily.
