Royal jelly is rich in nutrients and active substances, and has a unique effect in bee colonies. It only attracted people's attention at the end of the 19th century and began to study it; by the beginning of the 20th century, scientists began to study chemistry, physiology, In-depth research has been carried out in pharmacology, clinical and other aspects, and brilliant achievements have been made. Royal jelly has now become a popular and enduring nourishing and nutritious health food and medicine all over the world. Domestic and foreign research results and clinical application practice have proven that the main functions of royal jelly can be summarized as follows: (1) Royal jelly has obvious inhibitory and killing effects on Escherichia coli, Staphylococcus aureus and Bacillus megaterium. The antibacterial and anti-inflammatory effect of royal jelly is related to the pH value. The smaller the pH value, the stronger the antibacterial effect. When the pH value is 8, its antibacterial effect disappears completely. The decenoic acid in royal jelly has extremely strong bactericidal ability. If the royal jelly is filtered with filter paper, the antibacterial and anti-inflammatory effects will be lost. In addition, royal jelly has antiviral effects. (2) Royal jelly can enhance physical fitness. Under harsh conditions such as hypoxia, fatigue, high depression, cold and fasting, it can enhance the body's adaptability and tolerance, and resist the attack of adverse external factors and damage to the body by harsh environments. To achieve the purpose of protecting the body, reducing mortality and extending life. (3) Royal jelly can replace aging and damaged tissue cells with new cells and promote the regeneration and repair of damaged tissue. It can strengthen the hematopoietic system and significantly increase the number of red blood cells in the blood. It can also improve the body's immune function and has strong resistance to radiation. (4) Royal jelly can regulate endocrine, have gonadotropin-like effects, excite the adrenal cortex, and rejuvenate the endocrine system that has lost control and balance. (5) Royal jelly can enhance tissue respiration, reduce oxygen consumption, and promote body metabolism. It can reduce blood sugar, blood lipids and cholesterol, adjust blood pressure, and has a good preventive and protective effect on cardiovascular and cerebrovascular system diseases. (6) Royal jelly can increase appetite, promote digestion, and strengthen the function of the digestive system. It can also enhance the activity of catalase, promote the recovery of liver function, and play a significant role in protecting the liver. (7) Royal jelly can regulate the balance of the nervous system and other systems, improve sleep, restore functional activities of the cerebral cortex, develop intelligence and enhance memory, and promote the normal growth and development of the body. (8) Royal jelly can promote and enhance the vitality of epidermal cells, improve cell metabolism, maintain the physiological nutritional balance of the skin, prevent the degeneration and hardening of elastic fibers. Make the skin more smooth, delicate, white, toned, elastic, reduce wrinkles, delay and delay The skin ages and remains youthful forever.
