Valerian (herb)

Valerian is a perennial flowering plant native to Europe and parts of Asia. It is also grown in North America. The plant is known for its medicinal properties and is commonly used in herbal medicine.

Description

Valerian is a hardy plant that can grow up to 1.5 meters tall. It has heads of sweetly scented pink or white flowers that bloom in the summer. The flowers are followed by a single-seeded fruit. The roots of the plant are used in herbal medicine.

Uses

Valerian has been used as a medicinal herb since at least the time of ancient Greece and Rome. Its therapeutic uses were described by Hippocrates, and in the 2nd century, Galen prescribed valerian for insomnia. In the 16th century, it was used to treat nervousness, trembling, headaches, and heart palpitations.

In modern times, valerian is used as a dietary supplement for insomnia, anxiety, and other conditions. It is also used in homeopathic medicine.

Active Compounds

The active compounds in valerian include valerenic acid, isovaleric acid, and a variety of alkaloids. Valerenic acid has been found to inhibit the breakdown of GABA in the brain, resulting in sedation. Isovaleric acid has a similar effect, while the alkaloids have a variety of effects on the central nervous system.

Side Effects and Interactions

While generally safe for most people when used in medicinal amounts, valerian can cause some side effects such as headache, excitability, uneasiness, and even insomnia in some people. It can also interact with certain medications, including some that are used for anxiety and insomnia.

Cultivation

Valerian is a plant that prefers the full sun or partial shade and is often grown in home gardens for its medicinal properties. It is also commercially grown for use in dietary supplements and other products.
