Description:
Chen Pi (Citrus reticulata) is a traditional Chinese herbal medicine prepared from the dried and aged peel of mature tangerine or mandarin fruit, primarily from Citrus reticulata and related Citrus species in the Rutaceae family. It is commonly known as Chen Pi, Aged Tangerine Peel, Dried Tangerine Peel, Dried Mandarin Orange Peel, Pericarpium Citri Reticulatae, and Citrus reticulata Peel. In Traditional Chinese Medicine (TCM), Chen Pi is traditionally valued for its ability to regulate Qi, strengthen the Spleen, harmonize the Stomach, dry Dampness, and transform Phlegm.
Chen Pi is traditionally considered an important herb for patterns involving digestive Qi stagnation, Spleen Dampness, and accumulation of Phlegm. It is traditionally associated primarily with the Lung and Spleen meridians and is commonly included in formulas intended to support healthy digestion, relieve abdominal fullness and bloating, regulate Qi, and address traditional Dampness and Phlegm patterns.
Chen Pi is traditionally used to regulate Qi and harmonize the Stomach. In TCM, it may be selected in traditional formulas for abdominal distension, bloating, reduced appetite, nausea, belching, and a sensation of fullness associated with Qi stagnation or digestive disharmony.
Chen Pi is also traditionally used to dry Dampness and strengthen the Spleen. It may be included in traditional formulas for digestive discomfort, loose stools, abdominal fullness, and a sensation of heaviness associated with traditional Spleen Dampness patterns.
Chen Pi is traditionally used to transform Phlegm and support healthy respiratory function. It may be combined with other herbs in traditional formulas for excessive phlegm, chest fullness, coughing, and sensations of congestion associated with traditional Phlegm-Dampness patterns.
Chen Pi is also traditionally used to promote the movement of Qi and improve the harmonious downward movement of Stomach Qi. It may be used in traditional formulas for nausea, vomiting, digestive stagnation, and abdominal discomfort.

Side Effects:
Chen Pi is generally used as a traditional herbal preparation under the guidance of a qualified practitioner. Some individuals may experience gastrointestinal discomfort, heartburn, abdominal irritation, nausea, or other digestive symptoms.
Because Chen Pi is derived from citrus peel and contains naturally occurring volatile oils and flavonoids, sensitive individuals may experience allergic reactions or skin irritation.
Excessive consumption may cause digestive discomfort in some individuals.
Discontinue use and consult a healthcare practitioner if unwanted symptoms occur.
Precautions:
Consult a healthcare practitioner prior to use if you are taking prescription medications or other natural health products, or if you have a medical condition.
Consult a qualified healthcare practitioner or Traditional Chinese Medicine practitioner before use if you have significant digestive symptoms, chronic gastrointestinal disease, or persistent abdominal discomfort.
Consult a healthcare practitioner before use if you have a known allergy or sensitivity to citrus fruits.
Consult a healthcare practitioner before use if you experience persistent nausea, vomiting, abdominal pain, diarrhea, or other unexplained digestive symptoms.
Do not use during pregnancy or breastfeeding unless directed by a qualified healthcare practitioner or Traditional Chinese Medicine practitioner.
Consult a healthcare practitioner before use if you have a serious or major medical condition.
Discontinue use and consult a healthcare practitioner if symptoms persist or worsen or if new symptoms develop.
Interactions:
Consult a healthcare practitioner before using Chen Pi with prescription medications or other natural health products.
Human clinical interaction data for whole-herb Chen Pi preparations are limited. The potential for interactions may vary according to the Citrus species, preparation, dose, duration of use, and other ingredients used in a formula.
Individuals taking multiple medications or combining Chen Pi with concentrated herbal preparations should consult a qualified healthcare practitioner before use.
Because citrus peel contains various flavonoids and volatile constituents, individuals taking medications that are significantly affected by citrus-derived compounds should seek professional guidance before using concentrated preparations.
Dosing:
Use according to the product label or as directed by a qualified healthcare practitioner or Traditional Chinese Medicine practitioner.
Traditional Chinese Medicine references commonly describe Chen Pi in an approximate range of 3–10 g when used as a decoction, although the appropriate amount depends on the preparation, formula, individual constitution, and clinical circumstances.
For a 50 g bulk-herb product, the package quantity should not be interpreted as a recommended daily dose.
Storage:
Store in a cool, dry place away from direct sunlight. Keep tightly closed and out of reach of children.
Preparation:
If using dried Chen Pi, prepare according to the directions provided by your Traditional Chinese Medicine practitioner or product instructions. Traditionally, Chen Pi is commonly sliced or broken into smaller pieces and prepared as a decoction or used as part of a TCM herbal formula.
Chen Pi may also be powdered or incorporated into traditional herbal preparations. Preparation methods can vary according to the intended traditional application and the other herbs included in the formula.
Scientific Support:
Chen Pi is primarily derived from the dried peel of mature fruits of Citrus reticulata and related Citrus species. It has a long history of use in Traditional Chinese Medicine, particularly for traditional patterns involving Qi stagnation, Spleen and Stomach Dampness, digestive discomfort, and Phlegm-Dampness.
Chen Pi contains naturally occurring flavonoids, polymethoxyflavones, essential oils, terpenes, and other phytochemicals. Compounds such as hesperidin, naringin, nobiletin, tangeretin, and related citrus constituents have been investigated in scientific research.
Modern pharmacological research has investigated Citrus reticulata peel and its constituents for potential antioxidant, anti-inflammatory, gastrointestinal, antimicrobial, metabolic, and respiratory-related activities.
Laboratory and animal studies have investigated extracts and isolated constituents of Citrus peel for effects involving gastrointestinal function, oxidative stress, inflammatory pathways, and other biological processes. These findings provide scientific interest in Chen Pi but do not establish that whole-herb Chen Pi is effective for treating specific medical conditions in humans.
Clinical evidence for Chen Pi varies according to the preparation, species, processing method, and health condition studied. Traditional use is extensive, but additional high-quality human clinical research is needed to establish specific therapeutic applications, effectiveness, safety, and dosing.
