What could be the side effects from taking St. John’s Wort?
Side effects from correctly administered usage are thought to be rare. The most common side effects include dry mouth, dizziness, gastrointestinal symptoms, increased sensitivity to sunlight, and fatigue. If you get drowsy or dizzy do not drive, use machinery, or do anything that needs mental alertness. Do not stand or sit up quickly, especially with advanced age. This reduces the risk of dizzy or fainting spells.
