Use the root of Aconite, do not abuse it! Radix Aconiti contains the toxic ingredient aconitine, which has an excitatory and paralyzing effect mainly on the heart muscle, vagus nerve and peripheral nerves, and is most serious to life-threatening. Therefore, it should be applied with caution. Regarding the dosage and usage of Radix Aconiti, the following two precautions should be taken: First, different people have different tolerances to Radix Aconiti, some people have no problem with 30-60 grams. Some people experience toxic reactions with just a few grams. Therefore, except for critical cases, should be careful, may start with a small dose (3 to 6 grams), if no response, can gradually increase, take an incremental approach, roughly 30 grams for the degree. After the effect, it is no longer necessary to use a large amount, can also take the same decreasing way, slowly reduce down. The second is the processing of cooked sapodilla, is soaked in brine and then steamed in a cage drawer, its toxic components will be destroyed, while the active ingredients remain unchanged. However, its steaming process is still empirical at the moment, and it is recommended that research units make some tests to provide the best processing solution for processors. The Japanese processing method is high temperature and pressure to destroy its aconitine lactone, so that the human soup is much safer and does not need to be decocted first and for a long time (of course, the amount of Japanese Chinese medical herbs is very small). In the current situation, if the dosage of the herb is large, it is still appropriate to make it into the medicine. It is better to add three or five slices of ginger, or a spoonful of honey to the decoction. The experience of Sichuan doctors is that the taste of the mouth is not numb. If the mouth feels numb, it should be decocted again. In addition, the water for decocting Radix Aconiti should be put at once, and no water should be added in the middle. The first symptoms of poisoning are dizziness, panic, numbness in the mouth, tongue, lips, and limbs, and unpleasant speech. This can be taken in a large bowl of rice water to relieve the symptoms of poisoning, and then 60 grams of licorice can be taken in a decoction. In addition to the above symptoms, the severe cases also see nausea and vomiting, cold and wet skin, chest tightness, slow and weak heart rhythm, falling blood pressure, premature beats, irregular heart rhythm, falling body temperature, or sudden convulsions, should be sent to the hospital in time for emergency treatment.
