Evidence supporting the use of: Citrus spp.
For the body system: Mucus Membranes
Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Citrus spp., particularly oranges, lemons, and other related fruits, have a long history of traditional use in supporting overall respiratory and mucosal health. In traditional medicine systems—including Ayurveda, Traditional Chinese Medicine, and European folk medicine—citrus fruits have been recommended for symptoms associated with excessive mucus, sore throats, and respiratory complaints. This is often attributed to their high vitamin C content, antioxidant properties, and ability to support hydration. Vitamin C, in particular, is well known for its role in immune support, which indirectly helps maintain the integrity of mucous membranes. However, while citrus fruits are rich in bioactive compounds such as flavonoids and vitamin C, direct scientific evidence specifically linking Citrus spp. with the targeted support or regeneration of mucous membranes is limited. Most modern studies focus on immune modulation or general antioxidant effects rather than direct mucous membrane support. Thus, while there is a clear tradition of use and some supportive mechanistic rationale, the evidence from controlled clinical trials specifically addressing mucous membrane health is not strong. The rating reflects that Citrus spp. are traditionally used and may offer some supportive benefits, but robust scientific validation for this particular use is lacking.
