In recent years, there has been a great breakthrough in the study of aloe components and pharmacology at home and abroad. According to Dr. W.Winters of the Health Science Center of the University of Texas in the United States, aloe contains at least 1.40 components, including components that control cell growth and differentiation, anti-infection components, components that stimulate the growth of white blood cells and other immune cells, components that heal wounds, and so on. And called aloe as "plant pharmaceutical factory". Dr. Tomita and Dr. Yumo Suzuki in Japan found that aloe contains aloin, an anticancer and detoxicating component, which has strong physiological activity. It also contains aloesin A, which has detoxification, antibacterial and antifungal effects, and aloin, which is very effective for burns, burns and ulcers. This component not only has anti-inflammatory effect, but also can promote tissue regeneration and repair. Because aloe is rich in physiologically active substances, its pharmacological effects are also very extensive.

Pharmacological effects of honey:

1. Nutrition: Honey contains a lot of carbohydrates, vitamins and trace elements necessary for human body, which can be absorbed and utilized by human body after taking it, and can also promote the recovery of injured tissues and increase the weight of animals. This is a special tonic, which can make the body strong.

2. Antibacterial effect: The antibacterial activity of honey comes from:

A. osmotic pressure. Honey is a supersaturated sugar solution, about 70% of which is fructose and glucose, and the water content is usually only 15-2 1%. Honey can inhibit the growth and activity of Helicobacter pylori, and has anti-oral streptococci, 2 1 bacteria, two kinds of molds, Leishmania parasites and diarrhea bacteria.

B. acidity. The pH value of honey is generally 3.2-4.5, and such a low pH value has an inhibitory effect on general bacteria.

C. generation of hydrogen peroxide. During honey brewing, the hypopharyngeal gland secretes glucose oxidase, which oxidizes glucose into gluconic acid and produces H2O2.

D. other bacteriostatic substances. Such as flavonoids and phenolic acids (caffeic acid, ferulic acid), terpenoids, benzyl alcohol, syringic acid, etc. After the biological activity of honey was removed by Bogdanov heating, the sample was separated into four substances: acidic, alkaline, nonpolar and volatile. The results show that the antibacterial strength is acidic > alkaline = nonpolar.
