What are the magical uses of egg shells?

　　egg The shell is the protective layer of the egg. It is composed of a matrix of protein fibers and calcium crystals accumulated on the matrix in a ratio of about 1:50 to form a calcareous eggshell. There is also an outer membrane on the surface of the eggshell, called the surface membrane. This surface membrane has a protective effect on the egg and prevents the egg from being contaminated by microorganisms. In general, the eggshell is composed of three parts, namely the outer eggshell membrane (surface membrane), calcareous eggshell and subshell membrane.

　　The subshell membrane has two layers: the outer inner eggshell membrane and the inner albumen membrane. They are composed of very fine fibers interlaced into a network structure. All mold spores cannot penetrate these two membranes, but their hyphae can enter. Therefore, the subshell membrane also prevents microorganisms from invading the egg.

　　How is the ingenious structure of the egg shell formed? It turns out that after mature follicles enter the fallopian tube, the fallopian tube secretes protein to wrap the yolk, and then gradually descends to form an inner and outer shell membrane. Finally reach the place where the eggshell is formed Uterus department. The uterus uses the carbon dioxide produced by its own metabolism to combine with water under the action of carbonic anhydrase to form carbonic acid. The carbonic acid further dissociates carbonate ions, and the resulting carbonate ions combine with calcium in the blood to form calcium carbonate. Calcium carbonate is evenly deposited on the egg membrane to form a hard egg shell. So the main component of eggshells is calcium carbonate.

　　In fact, egg shells mainly contain inorganic matter, reaching 94% to 97%, while organic matter is only 3% to 6%. Among the inorganic substances, calcium carbonate has the largest content, 93%. In addition, it also contains 1.0% magnesium carbonate, calcium phosphate and magnesium phosphate. The organic components are mainly collagen protein, water and a small amount of lipids.

　　In addition to protecting eggs, egg shells also have many uses in our daily lives, such as beauty, anti-inflammatory and analgesic, cleaning, etc.

　　The beauty benefits of egg shells

　　It is well known to us that eggs have a very good effect on skin beautification. It is said that Cleopatra and Empress Dowager Cixi both used eggs for beauty. However, the eggs we use for beauty are all shelled eggs, and no one uses eggshells for beauty. So, do eggshells have any beauty effect? It can't help but arouse our questions.

　　In fact, eggshells also have cosmetic effects, especially the subshell membrane, which is the innermost layer of the eggshell, has a very good cosmetic effect. It is called "Phoenix Clothes" and is rich in collagen. Apply it to the face or nose or chin to remove blackheads and dead skin. And the egg white liquid in the innermost layer of the egg shell can be used for beauty. Take a little bit and add a small spoonful of milk powder and honey to make a facial mask. Apply it on the face. Wash it off after 30 minutes to make the skin look brand new. If used frequently, you can use skin Really as delicate and smooth as an egg.

　　We eat a lot of eggs. I wonder what the egg shells taste like?

　　Maybe you don’t know that egg shells can be eaten. Egg shells are rich in calcium and can be made into a slimming meal. The specific method is: wash the egg shells, fry them over low heat, grind them into powder, and then mix them with rice to make calcium rice. A small bowl of calcium rice and a small plate of vegetable and egg salad can not only supplement the nutrients needed by the human body, but also help lose weight and improve beauty.

　　It seems that eggs are treasures inside and out! Its contribution to us is truly understandable!

　　Medicinal properties of egg shells

　　Except for using egg shells to make small crafts when we were children, we basically discarded them, mainly because their effects are not widely understood. In addition to the cosmetic effects of the inner membrane of egg shells, it also has some medicinal effects, such as:

　　1. External application of the powder made from crushed egg shells can treat wounds, reduce inflammation and relieve pain. The egg membrane inside the egg shell can also treat burns and relieve pain.

　　2. The calcium carbonate content of egg shells is as high as 90% and also contains a small amount of sodium carbonate, hydrogen phosphate and other substances. When crushed into powder and taken orally, it can treat rickets in children.

　　3. The powder made from fried yellow egg shells can be taken with boiling water. diarrhea ; Taking it before or after meals can relieve stomach pain, and has analgesic and antacid effects on patients with duodenal ulcer and hyperacidity. In addition, the eggshell powder and licorice powder are evenly mixed. Adding an appropriate amount of rice wine and drinking it can also treat dizziness in women.
