Valerian – (Valeriana officinalis)


Valerian is a hardy perennial plant native to Europe and parts of Asia. It has been introduced to North America and other parts of the world. It blooms from June to September with pink or white fragrant flowers. When used in cut flowers, the scent can be overpowering. It has been used since the days of ancient Greece and Rome. In the 16th century, the herb was used as a perfume. During World War II, it was used in England to ease the stresses of air raids.

Key Medicinal Uses

Internally – Valerian is used most commonly as a sleeping aid for insomnia. It is also used frequently for anxiety. With its sedative qualities, it is often used for neuralgic pain, hypochrondriasis and nervous unrest. It can address nervous overstrain of the system. Some use it to strengthen the eyes.

It has some slight influence on the circulatory system. It slows the heart and increases its force. Due to this it is sometimes used for cardiac palpitations.

Children and pregnant and nursing women should not use valerian and other anxiety or insomnia medications should not be combined with this herb. Side effects may include dizziness, headache, itchiness, daytime drowsiness, stomach upset, vivid dreams and dry mouth. There is a very rare occurrence of liver damage associated with the herb, so excercise caution. Watch for signs of intense itching, excessive tiredness, vomiting, nausea, pain or discomfort on the upper right portion of the abdomen, or yellowing of the eye whites or skin. If any of these symptoms occur, see a doctor immediately.

Valerian may interact with other sleep aids or anxiety drugs. It may also interact with other sedative herbs like catnip and hops. Valerian is broken down in the liver, so it could possibly interfere with other medications that are broken down by the same liver enzymes like allergy medications, cholesterol medications, cancer drugs or antifungal drugs.

Preparation and Dosage

The herb can be found in commercial preparations as capsules, herbal teas, tablets, and liquid extracts. Follow the directions on the label carefully and watch for side effects. Due to standardization problems, commercial preparations are the best way to take. If you choose to use the raw herb, however, typical doses vary from 1 to 10 grams per day. While valerian is non-toxic, large doses may cause side effects.
