The so-called "external caution and cold" refers to avoiding all exogenous pathogens such as wind, cold, summer heat, dampness, dryness and fire that affect health and the function of human viscera, mainly including:
External evil and six evils, also known as virtual evil and thief wind, that is, external caution and internal cold are to prevent external evil and six evils from invading the human body. Huangdi Neijing first put forward this principle of health preservation. The first chapter of Ancient Innocence says: "Under the guidance of ancient sages, husbands were called evil spirits and thieves. Sometimes they will avoid it, but they are indifferent and empty. With the true spirit, the spirit is hidden inside, and the disease is always safe. " ? There is also "waiting for the virtual wind and avoiding it" in the eight winds of Jiugong. Zhang Zhongjing is well versed in the purpose of Neijing. In synopsis of the golden chamber, he put forward that "Confucian evil wind will kill many people" and clearly pointed out the seriousness of Confucian evil wind and even death. "synopsis of the golden chamber? It is recorded in "Diseases of Zang-fu Organs and Meridians in Past Dynasties" that modern people advocate "prevention before illness" in health care, which actually tells us to "be cautious about cold" and avoid external evils from harming the human body. It should be emphasized that the evil wind mentioned by Zhang Zhongjing refers to all external factors that can damage the normal function of human viscera and lead to diseases. Even if the exogenous pathogen has not yet entered the viscera, it should be treated as soon as possible, or guided, inhaled, or acupuncture, ointment and friction, so as to dredge the meridians and activate the bones and muscles. It is still of great significance to today's medical care, disease prevention and control.
Zhang Zhongjing's proposition that health care and treatment do not violate national laws has profound social significance. Because you break the law, you will be tortured to extract confessions, work, restrict freedom and other measures. At the same time, it also requires paying attention to psychological health care, which is called emotional health care in modern times. In ancient times, criminals were tortured to extract confessions, with complete instruments of torture and tragic execution. Some people skin their bodies hungry, burn their asses, exile, get involved, and so on. What's more, when Shang Yang was put to death, he was sentenced to a car crack. The victim's skin was raw, his bones and muscles were injured, his internal organs were injured and he died. At the same time, illegal imprisonment, coupled with some severe criminal laws, such as castration and humiliation, will do harm to the spirit of criminals, easily cause huge psychological burden, affect people's emotions, and may produce bad emotions such as fear, worry and disappointment, thus affecting people's physical function decline and low immunity and getting sick. It is not difficult to understand that many criminals' hair turned white overnight after being arrested. This is a case in which a person's physical condition is affected by emotional changes.
Zhang Zhongjing's integration of observing national laws into the health rules more than two thousand years ago is a great pioneering work, which still has important practical significance in today's rule of law. When obeying the law is no longer just a social need, but a pursuit of health, people will cherish their health and integrate into the legal concept, which will play a positive role in promoting the country and society. On the contrary, breaking the law will not only be punished by law, but also affect our health. Finally, the damage caused by the golden blade of insects and beasts means that we should avoid being bitten by insects and beasts or the trauma caused by sharp weapons, which will damage the healthy qi of the human body. In this way, "nourishing healthy qi from inside" and "being cautious and cold from outside" are organically combined.
