It is recorded in ancient books. Let me analyze it for you slowly:
The ancient book "Shen Nong Ben Cao Jing" records: "Those above the chest diaphragm should take medicine first; If you are sick below the heart, take medicine first and then eat; If the veins of the limbs are sick, it is advisable to eat on an empty stomach; People with bone marrow diseases should eat at night. "
It means:
1. If the lesion is in the heart and lungs, that is, the visceral lesion is in the upper jiao (above the diaphragm), it is best to take medicine after meals.
2, the disease occurs in the viscera below the diaphragm (heart, lungs, viscera below), it is best to take medicine before meals on an empty stomach.
3, when the lesion is in the blood vessels or meridians of the limbs, it is best to take it on an empty stomach in the morning.
4. When the lesion is in the bone marrow and the position is deep, it should be taken after meals at night.
It is best to take it on an empty stomach when taking tonics or antidiarrheal drugs.
6. When taking sedatives, it is best to take them before going to bed at night.
7. Drugs that are irritating to the gastrointestinal tract are best taken after meals.
8. Of course, there are also special circumstances, such as acute serious illness, which is not timely, because controlling the disease is the first priority. Chronic diseases can be taken on time and in quantity. The drug for malaria was taken 2 hours after the onset, but now malaria has been eliminated. Drink ten jujube soups in the morning and eat Ji Ming powder around five in the morning.
Therefore, different kinds of traditional Chinese medicine have special requirements on the taking time of traditional Chinese medicine according to different situations.
