A number of these applications were likely passed down in the oral histories particularly of coastal dwellers and those using different seaweeds as food and treatments for common ailments. The beneficial use of many types of seaweeds was reported and recorded into some of the first written medical texts. The common benefits of these seaweed concoctions and applications seems to be linked to the presence of hydrocolloids and the various bioactive compounds. We believe this collation brings together, for the first time to our knowledge, a number of excerpts from major medical publications and esteemed writers of the day. It provides a rich background supporting the positive applications of various seaweeds to a multitude of human ailments, from skin to bowel, inside and out and many of the places in between!
