The use of dietary supplements in pediatrics: a study of echinacea

Alternative medical therapies are commonly used and have increased in popularity. Although patients may not always disclose the use of alternative therapies, they may seek advice regarding their use, especially for children. Regulation and standardization of these modalities, especially botanicals, is incomplete. The University of Arizona has initiated a study of the use of echinacea in the prevention of recurrent otitis media. A review of echinacea preparations was undertaken, and this report discusses the complexities surrounding the use of this dietary supplement. The number and diversity of echinacea preparations are detailed; the role of the physician as "botanical" advisor to patients and families is examined.
