Xylitol, a natural sugar found in some fruits, interferes with the growth of some bacteria that may cause ear infections.^2,3,4 In double-blind research, children who regularly chewed gum sweetened with xylitol had a reduced risk of ear infections.^5,6 However, when they only chewed the gum while experiencing respiratory infections, no effect on preventing ear infections was found.⁷

Echinacea has been reported to support healthy short-term immune response. As a result, it has been suggested that some children with recurrent ear infections may benefit from ⁸ 1–2 ml (depending on age) of echinacea tincture taken three times per day or more.⁹ Doctors who use echinacea suggest that supplementation be started as soon as symptoms start to appear and continued until a few days after they are gone. Nonetheless, research has not been done to determine whether echinacea supplementation either reduces symptoms or prevents recurrence of ear infections.

Ear drops with mullein, St. John’s wort, and garlic in an oil or glycerin base are traditional remedies used to alleviate symptoms, particularly pain, during acute ear infections. No clinical trials have investigated the effects of these herbs in people with ear infections. Moreover, oil preparations may obscure a physician’s view of the ear drum and should only be used with a healthcare professional’s directions.

An unpublished clinical trial of children with colds found that linden tea, aspirin, and bed rest were more effective than antibiotics at speeding recovery and reducing complications such as ear infection.¹⁰ (Aspirin is no longer given to children due to the threat of Reye’s syndrome.) However, no research has yet confirmed the use of linden for preventing ear infections.

Caution: It is likely that there are many drug interactions with St. John's wort that have not yet been identified. St. John's wort stimulates a drug-metabolizing enzyme (cytochrome P450 3A4) that metabolizes at least 50% of the drugs on the market.¹¹ Therefore, it could potentially cause a number of drug interactions that have not yet been reported. People taking any medication should consult with a doctor or pharmacist before taking St. John's wort.

Vitamin C supplementation has been reported to stimulate immune function.^12,13 As a result, some doctors recommend between 500 mg and 1,000 mg of vitamin C per day for people with ear infections. Nonetheless, vitamin C supplementation has not been studied by itself in people with ear infections.

Zinc supplements have also been reported to increase immune function.^14,15 As a result, some doctors recommend zinc supplements for people with recurrent ear infections, suggesting 25 mg per day for adults and lower amounts for children. For example, a 30-pound child might be given 5 mg of zinc per day while suffering from OM. Nonetheless, zinc supplementation has not been studied in people with ear infections.
