Red seaweeds are popular and economically important worldwide and also well known for their medicinal effects due to the presence of phycocolloids. Carrageenans, the major phycocolloid group of red algae, have been extensively investigated for their vast array of bioactivities such as anticoagulant, antiviral, cholesterol-lowering effects, immunomodulatory activity, and antioxidant. Carrageenan possesses promising activity both in vitro and in vivo, showing promising potential to be developed as therapeutic agents. In this chapter, attempts have been made to examine the health benefit effects of carrageenans.
