Inappropriate use of camphor-containing products may be a common and underappreciated cause of seizures in young children, according to a new study by researchers at Albert Einstein College of Medicine of Yeshiva University.
The study, published in this month's issue of Pediatrics, calls for efforts to educate communities about the hazards of camphor and to crack down on illegally marketed camphor products.
Camphor - a naturally occurring waxy substance with a strong, aromatic odor, found in wood of the camphor laurel tree - is found in many consumer products. Scientists have known for some time that camphor can cause serious health problems, including seizures.
Children are particularly vulnerable to the toxic effects of camphor, which is easily absorbed through the skin and mucous membranes. As a result, the FDA limits the camphor content of common cold preparations, and federal and New York City regulations require that camphor-containing products be properly labeled.
Nevertheless, camphor products without proper or complete labeling are widely available and commonly used for medicinal, spiritual and aromatic purposes and for pest control, especially in the Hispanic community.
The Einstein researchers report on three cases of camphor-associated seizures in children seen in the emergency department of a single New York City hospital-Children's Hospital at Montefiore in the Bronx - over a two-week period.
