It is a medicine that has a few points of partiality, and this partiality is not poisonous if it is correct for the evidence, and it is poisonous if it is not correct for the evidence (the harm produced by the partiality).

The ancient saying goes, "A medicine is three times poisonous." China's earliest medical monograph "Nei Jing" on how to use medicine is very delicate, will be divided into big poison, often poison, small poison, no poison. The treatment of disease requires that the big poison cure the disease, ten to remove its six; often poison cure the disease, ten to remove its seven; small poison cure the disease, ten to remove its eight; non-toxic cure the disease, ten to remove its nine. Nowadays, many people think that most of the Chinese medicine originated from natural plants and animals and pure Chinese medicine preparations, more than the chemical nature of the drug calm and safe, always think that the drug will not occur toxic side effects. In fact, it is not, if arbitrary abuse, indiscriminate use of medicines and stones, the same will also occur toxic side effects.

Initial Explanation

There are a few points of bias in medicine. And if this partiality is correct, it is not poison, and if it is not, it is poison (harm produced by partiality).

According to the literature, it has been found that can kill more than 20 kinds of Chinese herbs, such as a large poisonous special treatment of rheumatoid arthritis Lei Gongteng, moderately poisonous roundworm repellent Chinese medicine bitter chair, poisonous resting wind spasmodic Chinese medicine centipede and so on. In Chinese herbal medicine there are some drugs are not only toxic, and even highly toxic, such as: mercury, zebra mussel, red arsenic, white arsenic, and so on.

Some raw medicines are still more toxic, such as raw epiphyllum, raw semicolon, strychnine, raw grass wool, horse beans, raw southern star and so on. These drugs after concoction, although the toxicity can be greatly reduced, but if abused or too much medicine, will still occur toxic side effects, or poisoning or even death. Therefore, when applying, should strictly control the dose. Reportedly, there was an "expert" with the epiphyllum treatment of rheumatism, due to the amount of medication (doubled), the results of the patient who is crying out for help.

Toxicity of the Chinese, herbal medicine, although it should be noted, but some commonly used Chinese herbs, but also still pay attention to the dose, if the amount of medicine is too large. The same will also lead to side effects. Such as licorice, medicinal properties and peace, can reconcile all the medicines have the function of stomach, with the tonic gas, fire detoxification, and ease of medicinal properties, and the effect of slow and urgent. However, if it is taken for a long time without any reason, it can affect the qi of spleen and stomach and hinder the digestive function; the overdose of Huang Yuzi can lead to liver damage and gangrene; the overdose of Mu Tong can cause kidney damage.

"It is medicine three poisons" source, according to the data show that the person who said this sentence is Liu Chun, Ming Dynasty physician, the original text is from the "medicinal treatment of the General Law Supplement". From the age, there was no western medicine at that time, it should refer to Chinese herbal medicine. The full text of this sentence is "medicine is three times poisonous, only appetizer is not poisonous, cover appetizer detoxification also". The Yellow Emperor's Classic of Internal Medicine categorizes Chinese herbs into four categories, namely, major poisons, frequent poisons, minor poisons, and no poisons, and there is a saying of "no poisons". The Divine Husbandman's Classic of the Materia Medica, which contains 365 types of Chinese herbs, including 120 top quality ones, clearly states that they are "non-toxic" and "prolong life".

Here we find that "medicine is three times poisonous" of "is", not "all" of "is". ". The "medicine" is not "all the medicine". The term "three points" is considered by some medical practitioners to mean "three points for treatment and seven points for nourishment". Look at the word "poison", there is a difference between the ancient and modern meanings of the word, the modern Chinese word "poison" means "harmful". Ancient "poison" has two meanings, one is "harmful", the other is "partiality" meaning, the ancient medical books in the era of the Neijing, most of the cases refers to The first one is "harmful" and the other one is "partiality", which is what the ancient medical texts of the Neijing era mostly referred to.

The ancients believed that as long as the drug is cold and hot, even if it is toxic, Chinese medicine scholars follow the ancient, Liu Chun is also along the meaning of "partiality".
