Is it useful to clear lung with pig blood in foggy days?

Haze refers to a state of air pollution. Haze is a general term for all kinds of suspended particles in the atmosphere, especially PM2.5 (particles with aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered as the "culprit" causing haze weather. With the deterioration of air quality, cloudy days are increasing and the harm is increasing. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather".

As more and more people are worried about their health, smog is inhaled into the lungs, and some small remedies for clearing the lungs are also circulating on the Internet. The most common thing is to eat pig blood, which can reduce or even avoid the damage of smog particles to the lungs. But as far as I know, pig blood can't clear the lungs. But pig blood can detoxify, clear intestines, enrich blood and beautify.

Because first of all, smog particles are inhaled and enter the lungs through the respiratory tract, thus endangering the health of the respiratory system. Eating pig blood enters the digestive tract and absorbs some harmful substances. It can be said that the two went their separate ways. Therefore, food can't prevent smog particles from damaging the lungs.

Pig blood is recorded in Compendium of Materia Medica as follows: Pig blood is salty and flat, and can be used as an indication for hematopoiesis, miasma, stroke, traumatic injury, fracture, headache and dizziness. In addition, pig blood can also inhibit stones and detoxify. Modern medical research has found that protein in pig blood, after being decomposed by gastric acid, can produce a substance that can disinfect and moisten intestines. This substance can react with harmful metal particles entering the human body, and then take these harmful substances out of the body through excretion, which is called the "scavenger" of human dirt.

Therefore, eating pig blood still has many benefits to the body. It can only be said that it is beneficial to clearing the lungs, but it is definitely not food for clearing the lungs.
