Chinese medicine has “three treasures of first aid”, namely Angong Niuhuang Pill, Zixue Dan and Zhi Bao Dan, among which, Angong Niuhuang Pill “leads the way”. It is one of the most prestigious traditional medicines for emergencies in China, and has been known since ancient times as “saving emergencies in an instant and saving the dying in a moment”. At one time, there was even a saying among the people: “After a stroke, take Angong Niuhuang Pill, it has the effect of bringing back to life.” Many people believe that Angong Niuhuang Pill is a life-saving medicine that can open up the brain and keep it at home for emergency use. However, is it really that “divine”? The actual “evidence” of a stroke and then take the medicine Angong Niuhuang Pill does have the effect of clearing heat and detoxifying, opening phlegm and orifices, and is a cool and open agent in Chinese medicine, often used to treat the acute phase of a stroke. However, not all stroke patients can take Angong Niuhuang Pill. In the opinion of Chinese medicine, stroke coma is divided into closed evidence and off evidence, and closed evidence is also divided into Yang closed evidence and Yin closed evidence, the symptoms are different between. The patient with Yang closed evidence often has confusion or drowsiness, red face, phlegm in the throat, stool obstruction, red tongue with yellow coating and other phlegm-heat internal closed performance; while Yin closed evidence is mainly phlegm-damp, heat symptoms are not prominent, such as low voice, indifference, yellow face, limbs limp, white tongue coating, etc.; Only stroke patients belonging to Yang closed evidence are suitable for taking Angong Niuhuang Pills, and should be dissolved with warm boiled water for delivery. If the patient is weak or cold, he should not use Angong Niuhuang Pill, especially if he is pale, restless, with white tongue coating, or if he is sweating profusely and his limbs are cold, he should avoid using it, otherwise it will aggravate his condition. In fact, we do not need to take Angong Niuhuang Pill as a family medicine. There are three reasons for this: first, from the price point of view, the price of Angong Niuhuang Pills is high. The price of each pill is around 360 yuan for the products of well-known manufacturers, and Angong Niuhuang Pill is not included in the medical insurance medication, so it needs to pay for itself, which is not economical. Second, from the preservation, drugs have a shelf life, pharmacies sold on the Angong Niuhuang pills are marked with a shelf life of 5 years. Although the drug is tightly wax sealed, even after the shelf life, the effect is not necessarily lost, but then it is best not to use. Third, from the point of view of use, because of the cold properties of the drug, pay special attention to the use of evidence, for the spleen and stomach deficiency cold, especially should be used with caution. Since it is difficult for the general public to identify the evidence, and since Angong Niuhuang Pill is a prescription drug, which means it is best used under the guidance of a doctor, the general public cannot simply use it casually. In hospitals, Angong Niuhuang Pill is mainly used to treat central nervous system diseases, such as stroke with impaired consciousness, traumatic brain injury, high fever and fainting convulsions, as well as encephalopathy caused by systemic diseases, such as pulmonary encephalopathy and hepatic encephalopathy, and is mostly used for critically ill patients, such as patients with stroke (including ischemic stroke and hemorrhagic stroke, first or second stroke), patients with severe traumatic brain injury caused by car accidents, etc. So, for those who have a stroke patient at home, you can have one or two pills on hand, after all, for emergency use, but ordinary families do not need to spare often. Coma patients can also “eat” medicine For coma patients, warm water can be used to open the Angong Niuhuang pill, and then fed through the nasal feeding tube or drip on the tongue to absorb the drug; in addition, the suppository of Angong Niuhuang pill can also be directly through the anus into the rectum.
