Question

Quizplus · Accepted Answer

Echinacea has been shown to potentially decrease the duration of the common cold in some studies. However, it has also been shown to interact with drugs taken for anxiety and high serum cholesterol, specifically with certain statin medications. Therefore, individuals taking these medications should use caution when taking echinacea as a supplement. The other supplement options listed (ephedra, St. John's Wort, and kava kava) have not been shown to be helpful for decreasing the duration of the common cold and/or have potential safety concerns.
