Irish Moss

Botanical Overview

Irish Moss (Chondrus crispus) is a species in the family. This species belongs to the family, a group of flowering plants. Although comprehensive ethnobotanical records are limited, phytochemical studies have identified 30 compounds in this species, suggesting potential medicinal value.

General Description

In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark purple or purplish-brown. The principal constituent is a mucilaginous body, made of the polysaccharide carrageenan, which constitutes 55% of its dry weight. The organism also consists of nearly 10% dry weight protein and about 15% dry weight mineral matter, and is rich in iodine and sulfur. When softened in water it has a sea-like odour. Because of the abundant cell wall polysaccharides, it will form a jelly when boiled, containing from 20 to 100 times its weight of water.
