Seaweed is a medicine for clearing away heat and phlegm, and it is also one of the familiar health foods. For example, now the beauty market launched the “seaweed mask”, decoration materials “diatom mud”, and so on are said to be pure natural, pollution-free. So, what is the role of seaweed in the end? Here we look at it together. Seaweed and “red tide” relationship “seaweed” is kelp, nori, wakame, stone cauliflower and other marine algae, is the growth of algae in the sea, usually fixed on the seabed or some kind of solid structure. Seaweeds are green algae, red algae, brown algae, bare algae, algae (or called eddy-flagellated algae), cryptophytes, diatoms, and so on, 13 doors a total of more than 10,000 species. Since seaweeds are rich in a variety of life-active substances, whether as daily food or extracting active substances as medicines, seaweeds have extremely advanced nutritional elements for human life. However, seaweed is also the “culprit” of red tide: when the seawater is polluted, get a large amount of organic matter, excess nutrients, temperature, sunlight, etc., some algae will suddenly bloom, so that the seawater will be discolored and red tide occurs. The algae that can trigger red tide are called “red tide algae”. After the red tide occurs, in addition to the seawater becomes red, at the same time, the ph value of seawater will also increase, the viscosity increases, and the plankton that is not red tide algae will die and decay; the red tide algae will also die in large quantities due to the explosive proliferation and excessive aggregation. At the same time, it will also cause the death of a large number of fish. Therefore, seaweeds can be used for health care and treatment of diseases; at the same time, they are occasionally the “black sheep” of the ocean.
