Pete took eight tablets, and that night, he felt too sick to go out
with his friends. Instead, he stayed behind at the motel. Several hours

WHAT’S IN YOUR
HERBAL SUPPLEMENT?
An estimated twenty thousand herbal products are sold legally in
the United States. Nearly one-fifth of American adults take herbal

fantastic claims about their products. They say their supplements can
do everything from relieving stress and anxiety to curing hyperactivity

public. Instead, the FDA receives reports of “serious adverse events”

and consumers. The FDA is responsible for investigating the safety
of a supplement only after it receives an adverse event report. The
organization received 600 reports of serious adverse events in 2008. It
also received about 350 reports of moderate or mild adverse events. The
number of all adverse events may be as high as 50,000 each year, the
FDA estimates. Many people don’t connect their illness or condition to
dietary supplements. They believe that most supplements—especially
herbal supplements—are safe.
