Case

The mother of a two-year-old with recurrent colds and ear
infections asks you if echinacea will help prevent these infections and if it’s safe for young children.

a. Question A is True.
Studies from several randomized, controlled clinical trials suggest that taking echinacea at the first sign of a cold can help reduce the duration and severity of cold symptoms.

European studies in vitro, in animals and in humans support the use of
echinacea in treating the common cold in adults. However, studies do NOT consistently support the use of echinacea as an effective prophylactic agent for upper respiratory infections. Furthermore, randomized, controlled trials have NOT been reported for children. Effects on immune function in adults appear quickly; many herbalists recommend that echinacea not be used for more than 8 to 12 weeks in a row. Although echinacea is widely used in Europe and the US, reports of toxic side effects (including allergic reactions) are quite rare.
