Tangerine red has the effect of regulating qi and relaxing the middle (regulating the qi of the spleen and stomach), which can cure lung cold cough and phlegm. However, the active ingredients in the infusion are limited and generally do not achieve the therapeutic effect. Tangerine red is pungent and bitter in flavor, warm in nature, and belongs to the lung and spleen meridians. Tangerine red can be used to regulate qi and broaden the middle, dry dampness and resolve phlegm (dispel dampness by drying dampness and dissolve phlegm) and other effects. Therefore, it can be used clinically for the treatment of lung cold cough, phlegm, vomiting (nausea, vomiting), lumpiness (pain and discomfort in the chest and stomach), food accumulation (indigestion of food and its accumulation in the stomach), belching (burping), breast lumps and other conditions. It should not be taken by people with yin deficiency and dry cough and prolonged cough with Qi deficiency. Adverse reactions are not clear. When patients feel unwell, they should go to the hospital for consultation and standardized treatment, and also need to follow up the consultation on time and strengthen the management of daily life. If you need to take orange red tea to regulate, you should follow the doctor’s instructions to use, not self-medication.
