There is no difference between tangerine red peel and tangerine red, both referring to the dried outer rind of the tangerine of the family Rutaceae and its cultivated varieties. Tangerine red is a traditional Chinese medicine recorded in the Chinese Pharmacopoeia and is indistinguishable from tangerine red peel. It is mild in nature, bitter and pungent in flavor, and belongs to the spleen meridian and lung meridian. It is good at drying dampness and resolving phlegm (expelling dampness by drying dampness and dissolving phlegm), and regulating the qi and relaxing the center of the middle (regulating qi and moving stagnation, so as to make qi in the chest smooth). Tangerine red is often used for food accumulation (food indigestion and stagnation in the stomach), wine injury (illness caused by excessive drinking), vomiting and nausea (vomiting and nausea triggered by poor stomach qi, stomach distension), cough and phlegm, etc. Clinically, it can be combined with hawthorn, Pueraria lobata, Semen ziziphi, Poria, Atractylodes macrocephala, Houpu, etc. It is not recommended for people with yin deficiency and dry cough. This medicine should not be used by people with Yin deficiency and dry cough. In addition, it has limited efficacy when applied alone and cannot replace the therapeutic effect of Chinese herbal tonics or proprietary Chinese medicines, and is recommended to be used in combination. Although tangerine red has no obvious toxic side effects, but as a drug can not be used indiscriminately, patients who need to use this drug, please consult a doctor in a timely manner, under the guidance of professional Chinese medicine practitioners to identify the evidence.
