Valerian, Valeriana officinalis, is a medicinal herb with sedative, antispasmodic and nervine properties. It is recommended for people who are in a “cold” condition, which means they might look pale, have cold hands and/or feet. It is not the ideal herb for those experiencing a “hot” condition as it is a warming nervine.

Garden Design: Valerian looks great in the back of the border, especially near a passage. This way one can enjoy the flower aroma as one walks by. If you dislike the smell of the flower, plant it in the back of the garden away from passages and buildings.
Companion planting: Valerian stimulates earthworm activity which helps the plants in the vicinity.
Note: Deadhead flowers in the summer to increase root production. Cats love the smell of the roots.
Best done on a warm fall day or in the spring. Harvest the root and the rhizomes of plants that are at least two years old. The roots contain essential oils, so be careful not to damage them while harvesting. Don’t rub, scrub, scrape or scratch the roots. Rinse the roots off with a garden hose. Use immediately.
Although valerian root is best used fresh, it can also be dried. After rinsing off the roots, cut the lengthwise and let them dry on flat surface in a well ventilated room. Alternatively, you can use a dehydrator set at 40 Celsius (104 F). The roots smell very pungent so consider which room is best to dry them. Store protected from light and moisture.
0.3-0.7 % essential oil (valeranone, cryptofauronol, valerenal, camphene, bornyl acetate and bornyl isovalerianate), iridoids, glycosides, lignan, traces of alkaloids.

MEDICINAL USE OF VALERIAN
When taken in the evening, valerian helps you prepare for sleep. It doesn’t necessarily help you fall asleep, but it improves the quality of sleep while reducing the amount of sleep needed. When taken during the day, valerian has a calming effect. It relaxes the mind and body, improves concentration and performance, and helps the body and mind better cope with stress.
Children with learning difficulties caused by nervousness and fear are greatly benefited by valerian.
Valerian is recommended for people who have poor blood circulation in general, but especially poor blood circulation in the brain and nervous systems.
For valerian to be effective, a high dosage is necessary. Often paradoxical reactions occur when the dosage is too low. Under 200 mg extract, valerian works as a stimulant. For the sedative effects, 900 mg extract is necessary.

Valerian is an edible plant and was regularly consumed in soups and stews in the middle ages. It fell into disuse, probably around the time Europeans started cultivating the potato.
Some people experience “paradoxical reactions”, which means that valerian stimulates them instead of sedating. This occurs more often when tablets are taken then infusions. For valerian to be effective, a high dose is necessary. Often paradoxical reactions occur when the dose is too low. Under 200 mg extract, Valerian works as a stimulant. For the sedative effects, 900 mg extract is necessary.
In the middle ages, people used valerian in perfume!
