It is likely safe to use valerian on the skin and to take it in small doses for a short time. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are pregnant or breastfeeding.

Interactions

Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse, such as:

  • People taking medicine for diarrhea should talk to their doctor before taking valerian. It may interact with the medicine.
  • People taking pain, anxiety, or sleeping medicine should talk to their doctors before taking valerian. It may interact with the medicine.
