Rating (out of 5): 1

Mandarin (Citrus reticulata) has a long history of use in Traditional Chinese Medicine (TCM), where its dried peel—known as Chen Pi—is valued for its ability to regulate qi (energy flow) and improve digestive and respiratory health. Within TCM, Chen Pi is sometimes believed to support circulation indirectly by promoting the movement of qi and blood, reducing stagnation, and addressing “dampness” in the body. However, these concepts are rooted in traditional frameworks rather than biomedical mechanisms.

Scientific evidence specifically supporting Mandarin or its peel for improving poor circulation is limited. Some laboratory studies suggest citrus flavonoids (such as hesperidin and naringin) found in various citrus fruits, including Mandarin, may have vascular protective effects and might modestly improve endothelial function, but direct clinical evidence for Mandarin improving circulation in humans is lacking. Most available studies focus on related citrus species or use isolated compounds rather than whole Mandarin or its peel. Therefore, while Mandarin is traditionally associated with supporting circulation within the TCM context, this is not substantiated by robust scientific studies. Its use for circulation should be regarded as primarily traditional, with minimal direct scientific backing.
