Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Citrus sinensis (sweet orange) has a long history of use in traditional Chinese medicine (TCM), where citrus peels (often referred to as "Chen Pi"—though this more commonly refers to Citrus reticulata, tangerine peel) are used to support the Spleen system. In TCM, the Spleen is considered central to digestion and the transformation of food into energy. Practitioners traditionally use dried citrus peel to "regulate Qi," strengthen the Spleen, and alleviate digestive disturbances such as bloating, poor appetite, and sluggish digestion. The rationale is based on centuries-old theoretical frameworks rather than on modern anatomical or physiological definitions of the spleen.

While there is some overlap in the use of sweet orange and related species (such as Citrus reticulata), sweet orange peel is sometimes used interchangeably in folk and traditional preparations. However, the majority of scientific studies focus on citrus fruits for their antioxidant, anti-inflammatory, and digestive effects, rather than direct support of the anatomical spleen or its immune functions. There is limited clinical research specifically validating the effects of Citrus sinensis on spleen health as defined by modern medicine. Thus, its use to support the Spleen body system is primarily justified by traditional frameworks, with modest evidence and little direct scientific validation.
