Spirulina is a spiral-shaped marine micro-plant, named Spirulina, also known as cyanobacteria, because of its shape. With a history of 3.5 billion years, it is one of the oldest creatures on earth. It has a strong ability of photosynthesis and adsorption of various elements. Distributed in tropical alkaline waters (oceans or salty lakes). The most suitable temperature is 25 to 35 degrees, and the temperature difference between day and night is about 1 degrees. Spirulina is rich in protein, vitamins, unsaturated fatty acids, various trace elements and other nutrients, and it is the most abundant, balanced and suitable nutrition among animals and plants found so far.

Discovery and origin of spirulina:
In p>1492, Columbus's fleet sailed into the Gulf of Mexico. As soon as the crew landed, they were surrounded by indigenous people holding spears, and one of the crew members was stabbed by the indigenous people, bleeding profusely. Columbus made it clear to the indigenous leaders what he had come for, and only then did he make peace. The crew who was stabbed was drowned because of excessive blood flow. A kind indigenous girl gave him a green cookie every day. Soon his wound healed and his body recovered quickly. This green cookie was made of spirulina produced in TEXCOCO Lake, Mexico.
In 194, when French pharmacist Kreiger visited Lake Chad in Africa, he found that in the desert where grazing and farming were impossible, the local aborigines were very strong. This aroused Kreiger's curiosity. He inspected their food deeply and found that they added spirulina dried in the sun to food or soup. Kreiger brought this green powder back to France, and gave it to Dr. Tangirqing, an algae scientist at the University of Paris, for analysis and test. He found that this green powder contains rich and balanced nutrients, which exceeds any living thing on the earth, because its appearance is spiral under the microscope. Therefore, it is called SPIRULINA. However, this great discovery was drowned by the smoke of World War II.
In 1942, when Dr. Kreman from French National Petroleum Research Institute visited Lake Chad in Africa, he found that there was a large amount of green algae growing in the local lake. At the turn of summer and autumn, the autumn wind began to rise, and the algae gathered together. The local people hunted for a living. Summer and autumn were the off-season of hunting. When there was no hunting to hunt, the local indigenous people would salvage the algae with very fine nets, dry them and make them into small cakes to eat. Eating this green cake for a long time makes the local people look particularly strong. Kreman returned to Paris with this green powder. The results showed that it was a spirochete-like algae with extremely rich nutrition, so this algae was named Spirulina.
In 1967, the 7th International Petroleum Conference was held in Mexico City. At the conference, Kreman introduced the discovery of spirulina and its research report, which caused a sensation. Shortly after the discovery of spirulina in Kreman, Spirulina was also found in Lake Tischikoko, a suburb of Mexico.
in 1973, the world's first spirulina cultivation farm was born on the lake of Tiszkoko, Mexico-human beings began to formally produce spirulina.
Up to now, there are more than 3, lakes in the world, and only Tishikoko Lake in Mexico, Chad Lake in Africa and Chenghai Lake in Yunnan, China can grow spirulina naturally.
The earliest spirulina culture in China started in Yunnan in 1985, and was included in the national key scientific and technological projects. Subsequently, spirulina factories all over the country were launched one after another and began to compete in the market. Hainan Spirulina stands out from the competition and becomes one of the two bases that go hand in hand with Yunnan. Spirulina likes to grow in tropical and subtropical areas with high temperature, dryness, good water quality and little rainfall. Abundant sunshine, pollution-free seawater and fresh and pure air make Hainan unique in cultivating excellent spirulina.

The six best spirulina:
1. protein content is about 6%, while soybean is 4%, milk powder is 13-22%, and lean meat is 16-22%.
2. Spirulina is rich in β-carotene (the content of vitamin A is 15 times that of carrot, and it is the highest among natural foods found so far).
3. The content of tocopherol (vitamin E) is the highest in plants.
4, (vitamin B12) has the highest content in plants.
5. The content of phycocyanin (used to prevent and treat cancer) is as high as 17%, which is the highest among plants.
6. The content of SOD (superoxide dismutase) reaches 2, to 6, units.
