The name Althea comes from the Greek word altha, meaning, "to cure" and suggests its long use in traditional herbal medicine. The French developed the original marshmallow confection as soft confections called "pate de guimauve," made from the root for throat infections and coughs. Today the popular candy bears the name marshmallow but does not contain any Althea, just corn syrup and gelatin.
Althea is considered to be one of the safest herbal demulcents due to the high amount of mucilage found in it. Use of the glycetract is preferred to the tincture as it better extracts the mucilage. The information provided is intended to augment the treatment from a naturopathic doctor or other trained medical professional. Although most herbs are generally safe, it is recommended that you avoid self-prescribing especially when there is an underlying ongoing medical condition, if you are on any prescription medications or if you are pregnant or breastfeeding.
