Citrus fruits, such as oranges, lemons, and limes, have a long history of traditional use in cultures around the world for managing coughs, including dry coughs. The use of citrus in this context is primarily based on traditional practices rather than robust scientific evidence. In traditional medicine systems like Ayurveda, Traditional Chinese Medicine, and folk remedies, citrus juices or infusions (often with honey) are commonly recommended for soothing throat irritation and suppressing cough. The rationale typically includes the presence of vitamin C, antioxidants, and the acidic nature of citrus, which is thought to help loosen mucus and provide relief from throat dryness.

However, scientific studies specifically evaluating citrus fruits for dry cough are limited. Some laboratory studies suggest that vitamin C and bioflavonoids in citrus may have mild anti-inflammatory and immune-supporting effects, but these do not directly address cough suppression or symptom relief in clinical trials. Most modern recommendations for citrus during respiratory illness relate to general immune support rather than as a proven cough remedy. As such, while citrus use for dry cough remains popular and is rooted in tradition, the level of scientific evidence supporting its efficacy is low.
