Negative effects of herbals on asthma control

Researchers from Mount Sinai School of Medicine, in New York City examined the association among the use of herbals and patients’ adherence to prescribed inhaled steroids, and drug treatment and disease beliefs.

First, the details.

  • 326 adults with persistent asthma were asked about their use of CAM (teas, herbs, and rubs) to treat asthma in the prior 6 months.
  • The relationships among herbal remedy use, adherence to inhaled steroids, and medication and disease beliefs were assessed.

And, the results.

  • 25% of patients reported using herbal remedies.
  • Herbal remedy use was associated with decreased adherence to taking inhaled corticosteroids and increased severity of asthma.
  • Herbal remedy users were also more likely to worry about the side effects of inhaled corticosteroid treatment.

The bottom line?

Based on these findings, the authors concluded, “Physicians should routinely ask patients with asthma about CAM use, especially those whose asthma is poorly controlled.”
