Valerian Root Warnings

Valerian root has been touted as a defense against anxiety and insomnia for several thousand years. Herb doctors and holistic healers have claimed that this European and Asian herb will also heal sores, relieve digestive disorders, and stave off heart problems. Modern scientific studies have failed to conclusively back up these assertions, though some tests seem to show that valerian may be of some worth as a sleep aid. Valerian root may be detrimental to your health, and should only be taken after consultation with a physician. It is contraindicated with several families of pharmaceuticals, and may cause physical side effects.

Physical Side Effects

• Valerian root's most commonly reported side effects include digestive disorders, headaches, dizziness, and a lowered body temperature. Some case studies appear to show that long-term use of valerian root may cause insomnia. Valerian has been evaluated in controlled tests against placebos, however, and side effects were no greater than those found in the subject group taking an inactive test substance.

Interactions

• Studies show that valerian root may increase drowsiness in people who are taking certain sedatives. Valerian root's strongest interactions seem to be with barbiturates, benzodiazepines, and narcotics. Other herbs may cause excessive drowsiness if taken with valerian.

Pregnancy and Children

• Without a medical consultation, valerian root is not recommended for women who are pregnant. Studies also advise that the herb should not be given to children under three years of age.
