What are some data on alternative therapies in treating upper respiratory infections?
Many alternative and cultural remedies are used in treating upper respiratory infections.
Herbal teas including elm bark and licorice root are thought to relieve sore throat and some studies have suggested benefits compared to placebo. Long-term use of these remedies has not been evaluated; however, prolonged use of licorice may cause elevation of blood pressure.
As noted above, honey has been shown to be beneficial in suppressing cough in children with upper respiratory infection and its use in hot water or tea with lemon juice is not uncommon. Ingestion of honey in infants, however, is not recommended as they are not able to properly digest the spores in honey which can result in infections.
Echinacea is another herbal remedy commonly used in treating upper respiratory infection. Research data failed to prove any significant benefit in altering the duration and severity of upper respiratory infection symptoms when Echinacea was used in children between 2-11 years of age as compared to placebo.
Oral zinc supplementation has been used in recent years to shorten the duration and reduce the severity of symptoms of upper respiratory infection and common cold. This therapy has been studied in children with upper respiratory infection and the results are mixed. The FDA has not approved the use of oral zinc to treat the common cold or upper respiratory infections. There are reports of nausea and unpleasant taste caused by oral zinc.
Topical nasal zinc products (Zicam nasal gel) has been also used to attenuate the symptoms of upper respiratory infection. Some studies suggest loss of the sense of smell (anosmia) associated with the use of this over the counter product. Therefore, the FDA recommended discontinuation of the use of intranasal zinc products in 2009.
The use of oral vitamin C is thought to shorten the duration of upper respiratory infection symptoms, but research data are inconclusive regarding the benefits of vitamin C.
