Agar Agar (also known as agar, or kanten) is the mucilage content drawn from several seaweeds. As a herbalist, I’ve always been fascinated with mucilaginous herbs and foods. The action associated with mucilage content in an ingested herb or food is referred to as ‘demulcent’. If used topically on the skin, the action of mucilaginous herbs is referred to as ’emollient’. Emollients and demulcents are soothing, cooling, moistening and calming for body tissues they come in contact with.
This is a mechanical more so than a chemical action; mucilages are sticky, gooey, and almost mucous-like… hence the name! This consistency is what provides soothing to irritated tissues.
