Can dried tangerine peel (Chen Pi) cause “internal heat”?

In daily life, dried tangerine peel (Chen Pi) is a traditional Chinese medicinal herb. As it is both a food and a medicine (“food-medicine homology”), it carries relatively few contraindications and may be safely consumed as a food.

Can Chen Pi cause “internal heat” (a concept in Traditional Chinese Medicine referring to excessive internal warmth or inflammation)?

Chen Pi is a qi-regulating herb without warming or tonifying properties; therefore, it generally does not cause “internal heat.” It is suitable for a broad range of individuals, especially those with spleen-stomach deficiency or food stagnation accompanied by qi stagnation. Chen Pi is primarily produced in Guangdong, Fujian, and Sichuan provinces. Botanically, it is the dried, mature pericarp of *Citrus reticulata* Blanco—a plant belonging to the Rutaceae (Rue or Citrus) family. Clinically, Chen Pi promotes spleen and stomach function, regulates qi flow, alleviates abdominal distension and fullness, suppresses nausea and vomiting, improves appetite, relieves coughing, resolves phlegm, and eases chest and diaphragmatic oppression. Its key therapeutic actions include regulating qi, strengthening the spleen, and improving appetite. In traditional Chinese medicine, Chen Pi is frequently used as a “guide herb” (Yao Yin Zi)—a substance that enhances the efficacy or directs the action of other herbs—and possesses significant medicinal value.

Chen Pi is simply dried tangerine peel. More precisely, it is the name of a commonly used traditional Chinese medicinal herb—the dried, mature pericarp of *Citrus reticulata*, processed and prepared according to pharmaceutical standards. While most traditional Chinese herbs possess food-medicine homology, excessive or prolonged intake—even of safe herbs like Chen Pi—may lead to adverse effects or unwanted reactions.

In daily practice, Chen Pi can be steeped in hot water for consumption. We hope this answer has been helpful to you!
