Frequently asked questions

What is marshmallow root good for?


Marshmallow (Althaea officinalis) is a soothing herb traditionally used to calm irritated tissues in the throat, chest, digestive tract and urinary tract. Its root and leaves are rich in mucilage, a gel-like substance that forms a protective, soothing layer over inflamed surfaces. This makes marshmallow a popular choice for dry coughs, sore throats, heartburn and an irritated gut. Its botanical name Althaea comes from the Greek word for “to heal.”

Is marshmallow good for dry coughs and sore throats?


Yes, marshmallow is one of the most traditionally valued herbs for dry, tickly, irritating coughs and scratchy sore throats. Its mucilage coats the lining of the throat, helping to soothe irritation and calm the urge to cough. Marshmallow is especially helpful for unproductive coughs where the throat feels raw and dry, and it’s often combined with herbs like thyme, mullein and liquorice in cough formulas.

Can marshmallow root help with reflux and heartburn?


Marshmallow root is traditionally used to soothe and protect the lining of the digestive tract, making it a popular herb for heartburn, reflux and an irritated stomach. Its mucilage forms a gentle coating over the oesophagus and stomach lining, helping to calm inflammation and discomfort. It’s often used alongside herbs like slippery elm and chamomile for digestive support. If you have frequent or severe reflux, see your healthcare professional.

Are marshmallow lollies made from marshmallow root?


They used to be. Marshmallow sweets were originally made by the ancient Egyptians and later the French, who whipped the sticky sap of the marshmallow root with sugar and egg whites to create a soft confection. Today’s marshmallows are made with gelatin instead and contain none of the herb’s soothing properties. The plant itself gets its name from the marshy places where it naturally grows and its membership of the mallow family.



How do you take marshmallow, and are there any side effects?


Marshmallow is commonly taken as a liquid extract, glycetract, capsule or as part of a cough syrup. It can also be made into a cold infusion by soaking the dried root in cool water for a few hours, which helps preserve its mucilage. Marshmallow is generally gentle and well tolerated when taken as directed. Because its mucilage may slow the absorption of medicines, take it at least two hours apart from any medication. Check with your healthcare professional before use if you have diabetes, are pregnant or breastfeeding, or take prescription medication, and check the label’s age guidance before giving it to children.
