Generally speaking, it is different. It depends on the weight and temperature control of Chinese herbal medicine, but if you cook the same amount into a half bowl and a bowl, there should be little difference. In essence, as long as the concentration is appropriate, the amount is not a problem. As the title suggests, the concentration of half a bowl of medicine is twice that of a bowl of medicine. Moreover, there is a great difference between Chinese medicine professionals and their own cooking, which may greatly reduce the curative effect because of various factors such as improper temperature control. Mahuang decoction is a traditional Chinese medicine prescription, which is specially used to treat exogenous wind-cold, aversion to cold and fever, head and body pain, wheezing without sweat, dry mouth, thin and white tongue coating and tight pulse. For example, Zhang Zhongjing recorded: "Mahuang Decoction is mainly used for patients with solar disease, headache, fever, body pain, low back pain, joint pain, bad wind and wheezing without sweat."

Objectively speaking, it is difficult to cook ephedra directly with electric medicine, and there is almost no foam. Subjectively, the safety awareness is not strong, so the requirements are relaxed and it doesn't matter if there is no bubble. The fact is, it's just that the dried herbs of ephedra are soaked for a period of time and then boiled, which is easy to bubble. If you cook directly without soaking, it is difficult to boil foam. Moreover, Ephedra can't take the disease as the prescription, take the pulse syndrome as the first, carefully differentiate symptoms and signs, and follow the doctor's advice. You can't take it for granted, you can't be the same, and you can't come to the opposite pulse syndrome. It can't kill a thousand enemies and lose 800. When cooking ephedra soup, you must eat the tight pulse. People with heart and kidney yang deficiency should not eat it. You must find a way to foam when cooking. If there is a need to drink Chinese medicine, it is best to find Chinese medicine, follow the doctor's advice and use it reasonably!

The greatest advantage of traditional Chinese medicine is holistic view and dialectical treatment. Therefore, in Chinese medicine, some diseases are not seen in a decentralized way, but people are regarded as a whole. Syndrome differentiation and treatment is to decide the follow-up treatment according to the symptoms of patients. In Chinese medicine, some diseases are divided into many symptoms. It is not a fixed disease, not a single disease, not a disease separated from it. For example, in the treatment, only after we make a clear diagnosis of its symptoms, will we carry out the later drug treatment accordingly, that is, we must know what kind of symptoms we are in, so as to carry out individualized treatment for patients. This is the advantage of Chinese medicine. Therefore, whether Mahuang decoction is a bowl or a half bowl has the same effect. Whether it is good or not depends mainly on everyone's physique and absorption. Needless to say, how to drink it.
