Extended data:

Spirulina, also known as "Arthrospira". Cyanophyta, family Trematodaceae, is a filamentous body composed of single cells or multi-cells, with a length of 200-500μm and a width of 5-10 μ m. It is cylindrical, loosely or tightly twisted in a regular spiral shape, like a clockwork, with about 38 species, most of which grow in alkaline salt lakes. Spirulina is rich in micronutrients such as protein, carotenoids and B vitamins, and has the functions of improving immune function and reducing blood lipid.

Spirulina belongs to "resource health care products", and its growth has extremely harsh requirements on the natural environment. The biological indexes of artificially cultured spirulina are far less than those of naturally grown spirulina. Only three lakes in the world can naturally grow spirulina: Lake Chad in Africa, Lake TEX-COCO in Mexico and Chenghai Lake in Lijiang, China. However, Chenghai Lake in China is a plateau closed inland lake, and the production of natural spirulina is also limited.
