Be the first to review this product

Some of the herbs found in the Sleep Relax Formula act as gentle nervous restoratives, calming anxiousness and quieting jangly nerves. Sleep Relax includes a standardized extract of valerian root with calming passion flower, hops and skullcap.
Valerian is renowned for its calming effect on adults and children alike. The principal active constituent in valerian is the volatile oil. A standardized extract ensures effectiveness as a sedative herb.

Passionflower "has been shown to make a non-addictive sedative that relaxes the nervous system. Passion flower seems especially helpful when physical or mental strain results in insomnia or stress." 1

It seems to have a refreshing effect on the nervous system, and it is mild enough to be used for children. Michael Weiner, herbalist and author, suggests that: " Passiflora incarnata may be our best tranquilizer yet. The dried leaves and stems both induce a natural sleep and calm hyperactive people Physicians could well recommend this plant to patients who want to wean themselves from synthetic sleeping pills and tranquilizers." 2

Hops are helpful for nervous disorders, anxious overwrought states, and insomnia. Hops are used for their sedative properties in many European countries.

Skullcap is a nervine tonic and a slow but steady nervous system restorative.

  • Given the mechanism of action of valerian involves the same sort of receptor sites as benzodiazepine drugs, valerian should not be used in combination with these drugs unless being supervised by a health care practitioner.
  • Examples of benzodiazepine drugs: Valium®, Dalmane®, Halcyon®, Restoril®.
  • These drugs are commonly prescribed for insomnia and anxiety.
  • This formula also contains passionflower. Many herbalists caution against using passionflower in anyone taking an antidepressant drug.
  • Theoretically, passion flower may enhance the effects of monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, and tricyclic antidepressants.
  • Consult your health care practitioner prior to use.
