Folk remedies have a saying that raw fish bile can go to fire and see. Recently, a sixty-year-old man bought grass carp and swallowed fish bile raw due to blurred vision, after which the old man began to have diarrhea, nausea and vomiting, and almost died. The doctor said it was caused by fish gall poisoning. The Chinese medicine book "The Criterion of Evidence and Treatment" once recorded that fish bile has the effect of clearing heat, detoxification, liver and bright purpose, so why is the elderly poisoned? How to use fish bile correctly?
Fish bile can cause poisoning in humans
Fish galls such as bluefish, grass carp, anchovies, silver carp, bream, carp, etc. can cause poisoning. Among them, poisoning caused by bluefish, grass carp and anchovies is the most common and typical. The main components of fish bile are bile salts, hydrocyanic acid and histamine.
Fish bile contains bile salts, which have strong toxicity, whether cooked to eat, swallowed raw, or sent with wine, more than 2.5g, poisoning can occur. The first damage is the kidneys and liver, of which kidney damage is the most serious, and acute renal failure is very easy to occur. It is mainly manifested by the appearance of oliguria, no urination, yellowing of the skin, and swelling of the whole body. It can also damage brain cells and the heart, causing lesions of the nervous system and cardiovascular system, and even coma. If it is not sent to the hospital in time for rescue, the mortality rate is very high.
Fish bile also contains a toxin called hydrocyanic acid, hydrocyanic acid belongs to the highly toxic category, the human body in a short period of time inhaled a high concentration of hydrocyanic acid gas, can immediately stop breathing and die. Not only is hydrocyanic acid present in fish bile, but also a small amount of hydrocyanic acid is also found in apple nuclei, which is not found in apple pulp. Hydrocyanic acid is deposited in large quantities in the body, which can cause symptoms such as dizziness, headache, and accelerated breathing rate, and may appear coma in severe cases. Although a small amount of consumption is not fatal, it will cause great harm to human health if it is consumed for a long time.
Another toxin in fish bile is called histamine, which can cause severe allergic reactions. In addition to the presence of histamine in the fish gall, when the marine fish meat is not fresh or rotten, the histamine in the fish body will be converted into histamine, after human consumption, there will be headache, nausea, tachycardia, various types of arrhythmias and hypotension and other reactions, severe can cause human collapse, shock and other symptoms.
Fish bile should not be taken casually
In the ancient book "Dietary Therapy Materia Medica", it is recorded that fish bile can "cure laryngeal closure." Take bile and alum ash, pills like beans, wrap them in the throat, spit out evil saliva for a long time, that is, the throat is open. Wax moon taken from it. "Fish bile can be seen to treat sore throat. The fish galls in the text mainly refer to the fish galls of the wrinkled lip shark white spotted star shark or other sharks, and not all fish galls can be used.
It is also recorded in the Chinese medicine book "The Criterion for Treatment" that fish gall has the effect of clearing heat, detoxifying, clearing the liver and eyes, and relieving pain, and can cure red swelling and pain. The book also clearly describes the use of methods: fish bile to cure flying blood red vein pain and violent red eyes need to use carp bile (five pieces), huanglian (to remove the whiskers, research end, half two), the medicine to mix the yellow lian end with bile, the porcelain box, steamed on the rice once taken out, such as dry, into a little honey, like cream, coated eyes, five or seven degrees a day. If you take fish bile to treat eye diseases, single-flavored fish bile does not have any pharmacological effect, it must be baked and ground into powder and then compatible with other drugs to make pills, in order to be able to reduce the fish bile toxin on the basis of effectiveness and take, and the dosage requirements are also very strict. It can be seen that the medicinal effect of fish bile is to be used externally after mixing with other medicinal materials, and can not be taken internally.
At the same time, the ancient medical monograph "Materia Medica" said very clearly: "Eye diseases are not wind and heat, but by the blood deficiency and dim, it is not suitable for use." It is clearly stated that fish have cold bile and cannot be used for hypochondria and the elderly and infirm.
Folk remedies should not be trusted
Folk remedies are different from the formal prescriptions of traditional Chinese medicine, and most of the home remedies have not been scientifically verified, and their efficacy is uncertain and can easily mislead people. Many people believe in "home remedies to cure serious diseases", but folk remedies are not an effective cure for everyone. The individual variations of home remedies are relatively large, and the efficacy will vary according to the season, region, and individual physical condition.
There are three main types of folk remedies: one is to win attention, made up, without any scientific basis. Some home remedies are coincidentally "effective", such as some patients in the early stage of hypertension, blood pressure itself will fluctuate, sometimes blood pressure is high, but after rest and life adjustment even without antihypertensive drugs blood pressure can be in a normal, perhaps such patients use this home remedy when the blood pressure is in a relatively stable normal period. It is not excluded that some folk remedies are indeed for some people and can play an adjuvant therapeutic effect. There is also a category of one-sided interpretation of ancient medical books, which eventually spread falsely.
All folk remedies have a certain degree of appropriateness. First of all, it is necessary to clarify the disease, and only an accurate diagnosis can be treated first. To choose a prescription according to your age and physical condition, you must master a de facto common sense of medication, and you must not hold a "try it" attitude and treat your body and life as a test product. Ask your doctor for guidance, depending on your condition, to determine which prescription to use, and don't make up your own mind.
Expert opinion
Zheng Ruidan, director of the Infectious Disease Department of the 175th Hospital of the People's Liberation Army
Because the bile of freshwater fish such as grass carp, bluefish, silver carp and carp contains histamine, bile salts and cyanide, it is highly toxic and can cause organ failure such as brain, liver and kidneys, and even death. Some components in fish bile do have the effect of clearing the liver and eyes, clearing heat and detoxification, but the dose must be strictly controlled. In addition, snake bile, bear bile, etc., also need to be specially refined and concocted before they can be medicated, and they are very particular about the dosage, and the public should not blindly take it.
Jiang Qihong, director of the Department of Gastroenterology of Wuhan Puai Hospital
Fish bile bile is highly toxic, great damage to the liver and kidneys, can also damage brain cells and myocardium, constitute nervous system and cardiovascular system diseases, serious can make people have acute liver failure and acute renal failure, assuming that not timely treatment, mortality rate of up to 90%.
Gong Wenbo, deputy chief physician of the Department of Traditional Chinese Medicine, Ningbo Hospital of Traditional Chinese Medicine
The Chinese medicine book "Evidence and Treatment Criterion" records that fish bile has the effect of clearing heat, detoxifying, clearing the liver and eyes, and relieving pain, and can cure red swelling and pain. However, because most fish galls are poisonous, and a small amount can cause poisoning, in fact, it is not recommended in regular hospitals. In Chinese herbal medicine, there are many alternative drugs that can play a role in clearing heat, detoxification, liver and eyes, and there is no need to risk your life to eat fish bile.

Toxins can also damage brain cells and myocardium, causing lesions in the nervous and cardiovascular systems. However, poisoning often occurs due to improper dosage and administration.

Fish bile is used as a medicine, and can only be effective after external use after mixing with other medicinal herbs, and fish bile cannot be eaten raw.
