Seaweed is the algae growing in the sea, which can also carry out photosynthesis in the weak sunlight of the deep sea, and has strong vitality. Also known as sea oyster, seaweed, some can be eaten, some can be used as medicine. In recent years, the medicinal and health care effects of its extract sodium alginate have been gradually developed. The clinical and experimental results show that its effect is remarkable and its operation is simple, and it is gradually recognized and accepted by the public. It is mainly used in the following aspects:

1、 Dietotherapy

1. Antiviral, anticancer. Proteoglycans extracted from seaweed can resist various viruses, including HIV and oncogenic RNA viruses.

2. Prevention of leukemia. Alginic acid can combine with radioactive element strontium to form insoluble substance, which can be discharged from the body, so that strontium will not cause leukemia in the body.

3. Lowering blood pressure. Large dose of seaweed (0.75 g / kg) has a significant and lasting antihypertensive effect on anesthetized dogs and rabbits. The water agent is stronger than tincture. Large dose of alginate can also make the blood pressure of animals drop temporarily (medium dose can make the blood pressure rise temporarily).

4. Anti hyperthyroidism (hyperthyroidism). The iodine contained in seaweed can be used to correct thyroid insufficiency caused by iron iodine, and can also temporarily inhibit the metabolic rate of hyperthyroidism and relieve symptoms, but it can not last long, only as preparation before operation.

5. Anti tumor. The middle-aged and old people who often eat seaweed seldom suffer from cancer. The results showed that 60% of the edible seaweeds in the sea of Japan had anti leukemia effect.

6. Prevent stroke, cerebral thrombosis and cerebral hemorrhage, and reduce the mortality and disability rate.

7. Protect the heart. Seaweed contains not only polysaccharides and fatty acids, but also selenium. German scientists found that selenium deficiency is one of the causes of cardiovascular disease.

2、 Beauty and skin care efficacy

1. Cure acne. 2. Remove wrinkles. 3. Sun protection. 4. Make up water.

3、 Pharmaceutical field: alginate and its salts have no subacute / chronic toxicity or carcinogenic reaction, and are gradually used in the pharmaceutical industry.

1. pharmaceutics: it can be used to prepare gel matrix tablets.

2. Stomatology: sodium alginate impression material gradually replaced the previous mixture of rubber and gypsum.

3. Others: as an obesity agent and a new drug for the treatment of stomach diseases, it has great medical value.

With the wide application of sodium alginate in food, industry and pharmacy, it has become an indispensable part of people's life. In recent years, "marine vegetable" has been put on people's table, and its effect on human health is not only the above, but also has a good preventive effect on many diseases of modern people. In view of its special functions, coupled with China's rich seaweed resources, we might as well put more "marine vegetables" on our own table.
