In making the sweet marshmallow, the root was previously used. Using the root extracts in order to flavour treats has been practised since ancient Eygptian times. The plant can be used to treat kidney stones and irritable bowel syndrome. It can also help external skin problems such as ulcers and boils. It can be gargled to help mouth ulcers.
It is used in middle-easten foods such as halva, and can be taken as a tea or as an extract.
