Marshmallow forms a shielding layer on the skin and lining of the digestive tract. It also contains chemicals that might decrease cough and help heal wounds.
Marshmallow leaf and root are used for pain and swelling (inflammation) of the mucous membranes that line the respiratory tract. they may be also used for dry cough, infection of the lining of the stomach, diarrhea, stomach ulcers, constipation, urinary tract irritation, and stones within the urinary tract.
People from time to time apply marshmallow leaf and root directly to the skin for pockets of infection (abscesses) and skin ulcers; and as a poultice for skin irritation or burns, and for other wounds.
Marshmallow root is implemented to the skin as an element in ointments for chapped skin as well as for pain and swelling of the toes and arms because of exposure to the cold.
