Spirulina is the botanical name of a single-cell micro-algae of less than 0.2 mm in length.
The name refers to the spiral-shaped structure of the plant. Spirulina grows naturally only in different alkaline salt lakes, which meet the required extreme conditions:
fierce tropical sun, an average water temperature of about 35 ° C and an alkaline pH of 9-11.
Under such conditions, virtually no other living organisms can live.
