Spirulina is a type of unicellular cyanobacterium, that resembles a spiral coil in shape. It contains the pigments - chlorophyll and phycocyanin, which give it a blue-green color.

Spirulina has a history of being used as a food source by the Aztecs and other Mesoamericans until the 16th century. Today, this microscopic cyanobacterium is cultivated largely in the United States, India, China, Myanmar, Thailand, and Pakistan.
