Lichenin

Lichenin is a complex polysaccharide occurring in certain species of lichens. It can be extracted from Cetraria islandica (Iceland moss).^[1] It has been studied since about 1957.^[2]

In popular culture

In his 1960 novel Trouble with Lichen, John Wyndham gives the name Lichenin to a biochemical extract of lichen used to extend life expectancy beyond 300 years.
