Citrus fruits and their extracts, particularly lemon and orange, have a long history in traditional medicine for supporting lymphatic health and addressing congestion. In various folk and herbal traditions, citrus is believed to promote lymph flow and help clear stagnation due to their high vitamin C content, antioxidant properties, and potential to thin bodily fluids. Essential oils derived from citrus peel, such as lemon essential oil, have also been used in aromatherapy and topical applications with the intent to stimulate lymphatic drainage and reduce swelling. However, the scientific evidence supporting these traditional uses is limited. While citrus does offer general health benefits—such as immune support and improved microcirculation—there is a lack of robust clinical trials or mechanistic studies directly linking citrus consumption or topical use to significant improvements in lymphatic congestion in humans. Most support comes from anecdotal reports and extrapolations from the known pharmacological actions of citrus bioactives, such as limonene and flavonoids, rather than direct evidence. Therefore, while citrus is traditionally used for this purpose, the evidence base is relatively weak, meriting a moderate evidence score.
