Mingfan's functions and effects

Powdered alum is very similar to the table salt we commonly use, both of which are white, fine particles. A large piece of alum looks like a white stone, but it looks cleaner than a stone. When we were studying chemistry, we came across alum. It was also introduced in chemistry books that one of the main functions of alum is to purify water, as it can absorb impurities in water. So besides this, what other functions and effects does Mingfan have?

The effect of alum

Eliminate phlegm, dry dampness, stop diarrhea, stop bleeding, detoxify and kill insects. Water purification: AL(OH)3 generated in water can absorb impurities in water and achieve the purpose of water purification.

The role of alum

Indications: Treat epilepsy, throat congestion, severe phlegm, hepatitis, jaundice, yellow swelling, gastric and duodenal ulcers, uterine prolapse, leucorrhea, diarrhea, epistaxis, mouth and tongue ulcers, hemorrhoids, scabies, water, fire, and insect bites.

Alum, also known as white alum, is a refined product of alum stone. Alum is cold in nature, sour and astringent in taste, and has a strong astringent effect. Traditional Chinese medicine believes that alum has the effects of detoxifying and killing insects, drying dampness and relieving itching, stopping bleeding and diarrhea, clearing heat and eliminating phlegm. Research in recent years has confirmed that alum also has antibacterial and anti-trichomoniasis effects. Some Chinese medicine practitioners use alum to treat diseases such as hyperlipidemia, duodenal ulcers, and hemoptysis caused by tuberculosis.

In addition, alum is also a traditional food improver and leavening agent, and is often used as an additive in the production of foods such as fried dough sticks, vermicelli, and rice noodles. However, since the chemical composition of alum is potassium aluminum sulfate, which contains aluminum ions, excessive intake will affect the body's absorption of iron, calcium and other components, leading to osteoporosis, anemia, and even affecting the development of nerve cells. Therefore, some nutrition experts suggest that we should try to eat less foods containing alum.

Alum is a traditional water purifier and has been widely used by people.

In recent years, it has been discovered that the aluminum contained in alum is harmful to the human body. Long-term drinking of water purified with alum may cause Alzheimer's disease. It is no longer recommended to use alum as a water purifier.

Five kinds of boiled water that you cannot drink

1. Water that has been boiling on the stove overnight or for a long time;

2. Boiled water that has been stored in a thermos for several days;

3. Residual boiled water after repeated boiling;

4. Water that has been boiled overnight or not boiled again in a water boiler;

5. Boiling water used for steaming rice and vegetables.

The reason why these boiled waters are not suitable for drinking is: when the water is boiled for a long time, part of the water turns into steam and escapes. Some minerals and inorganic salts originally dissolved in the water, as well as some other chemical elements, will be reduced to a very toxic substance, such as nitrite ions, which can cause blood poisoning in the human body.
