The Chinese medical term for deficiency without tonic refers to people who are physically weak and need to take tonic, but after taking tonic medicine or eating tonic, it does not play the role of tonic, or even have adverse reactions, often manifested as dry mouth and bitter mouth, constipation, epistaxis (nosebleed), sore throat, insomnia, etc. The main reason for deficiency without tonic is that the spleen has the function of transporting water, grain and essence, and the stomach has the role of accepting putrefaction (carrying and digesting food).
The main reason for not taking tonic is the weakness of the spleen and stomach, the spleen has the efficacy of transporting and transforming the essence of water and grains, and the stomach has the effect of accepting and digesting food (carrying and digesting food), and when the spleen and stomach are weak, the function of transporting and accepting and digesting food decreases. And supplements are mostly nourishing and greasy in nature, not easy to be absorbed by the body after taking, there will be abdominal distension, nausea (no appetite, less food), constipation and other symptoms.
In addition, in the absence of identification of the type of use of tonic, but also easy to lead to the emergence of the symptoms of deficiency not to be supplemented. For example, if people with deficiency in both yin and yang only take warm tonic products, it will damage the yin fluid, resulting in sore throat, constipation, epistaxis and other symptoms; if you take yin tonic medicines, it is easy to damage the yang qi, abdominal pain, diarrhea, loss of appetite and other symptoms.
Therefore, people with weak physique should take appropriate supplements under the advice of doctors, and should not blindly use them on their own.
