Aloe vera L. is generally called Baba Aloe and Cuiye Aloe.

Also known as real aloe vera and desert lily. It is the most widely used variety in food, medicine and beauty. It originated in northern Africa and is now the most cultivated in America. Japanese, Korean, Taiwan Province and Hainan Island also have commercial cultivation, which is mainly used to extract aloe juice. Aloe vera is the original plant of aloe vera. Later, as a result of artificial selection, many varieties of Aloe Vera were selected, such as Aloe Vera Chinensis and Aloe Vera Shangnong.

Aloe sinensis. China aloe, also known as striped aloe, is cultivated in many areas in southern China. Aloe barbadensis and Aloe barbadensis are very similar. They are both varieties formed by long-term natural selection after being introduced into China, and they have strong adaptability to the climatic conditions in China.

Shangnong aloe vera. Aloe vera is a cultivated variant introduced from the United States by the Plant Science Genetics and Breeding Laboratory of Shanghai Agricultural College. There are white spots on the back and leaf surface of leaves at seedling stage, which disappear after plant growth. Shangnong Aloe grows fast and has great value in development and utilization. Potted plants, with weak tillering ability, unbranched main stems and slow natural reproduction.

Aloe arborescens. The main stem of Aloe arborescens is obvious and looks like an upright tree, hence the name. There are many plants in Japan, and there are also plants in Northeast China.

Green crocodile aloe (Cape Aloe). Aloe crocodile originated in Cape Town, Africa, also known as Cape Aloe, also known as Cape Aloe. Because the dry block of Aloe Vera from Cape of Good Hope is brown-black and loose in texture, it is different from the dry block of Aloe Vera from Cura? ao, so it is called new aloe vera.

The role of aloe vera

More features:

1996, FAO recommended aloe as "the best healthy food for human beings in 2 1 century".

1. Antibacterial and antifungal effects

The antibacterial effect of aloe stems from the cytokine function of aloin, which has relatively aggressive biochemical characteristics, so that aloe can directly kill bacteria.

2. Antiviral pathogens

Literature reports that aloe vera can promote the recovery of animals and people infected by virus. These documents mentioned feline leukemia virus and AIDS, and aloe vera played an amazing role in the rehabilitation of cats infected with the virus. There are also some papers that report that carbohydrate analogues in aloe can stimulate cells to produce antiviral substances-interferon.

3. The role of immune stimulators

The function of aloe immunostimulant is the basic function of aloe on human body. Aloe vera improves the immunity of the body, which makes aloe vera have remarkable curative effect in treating some diseases caused by decreased immunity.

4. Anti-inflammatory effect

Anti-inflammation is an important function of aloe gel. Whether it is burn, physical injury, corrosive chemical injury or inflammation caused by ultraviolet rays and thermal radiation, aloe gel has analgesic and anti-inflammatory effects. Experiments show that the efficacy of anti-inflammatory drugs made of aloe vera gel is equivalent to that of anti-inflammatory drugs synthesized by modern chemistry, while aloe vera gel contains no harmful components and has no side effects on human body.

5. Wound healing effect

Another important function of aloe vera gel is to promote wound healing. Aloe vera has a remarkable effect on promoting the healing of wounds and ulcers. When any part or tissue on the body surface is injured, wound healing is the main problem, and aloe vera gel can participate in this healing process.

6. Enhance the functions of phagocytosis, detoxification and cleaning.

Another important function of aloe is its remarkable "swallowing" effect. The body's immune system eliminates bacteria, infections and dead cells in the body through "phagocytosis". On the one hand, immunostimulants have phagocytosis, on the other hand, detoxification and cleaning functions in the body also have phagocytosis. For the body, bacteria and bacterial residues are poisons that must be removed from the body. Cells that are infected by bacteria and die in the body are also harmful to the body. These dead cells and toxins will be eliminated from the body through phagocytosis. Therefore, enhancing phagocytosis is to enhance the detoxification and cleaning function in the body. If a person suffers from chronic diseases due to the accumulation of toxins in cells or tissues in the body, but insists on natural therapy, taking drugs made of aloe can obviously enhance the detoxification and cleaning functions of the body. It is reported that aloe has therapeutic effect on 100 chronic diseases.

7. Immune and anti-tumor effects

The polysaccharide contained in aloe can improve immunity, and has a strong effect of inhibiting or destroying abnormal cell growth, thus playing an anti-tumor role.
