What herbs and supplements can interact with valerian supplements?

A Answers (1)

  • Based on theoretical concerns, valerian may increase the amount of drowsiness caused by some herbs or supplements.
    A brief episode of confusion was reported in one patient during use of valerian with loperamide (Imodium®) and St. John's wort (Hypericum perforatum L.). Nausea, sweating, muscle cramping, weakness, elevated pulse, and high blood pressure were reported after a single dose of a combination product with St. John's wort, kava, and valerian. Valerian may interact with certain herbs and supplements that are metabolized by the liver.
    Based on secondary sources, valerian may have antispasmodic properties.

    You should read product labels, and discuss all therapies with a qualified healthcare provider. Natural Standard information does not constitute medical advice, diagnosis, or treatment.
