Edible Uses:
The root of sitka valerian is edible cooked. Having a strong flavor, it needs to be steamed for 24 hours. The raw roots may be poisonous. The seeds can be parched.

Medicinal Uses:
Valerian is a well-known and frequently used medicinal herb that has a long and proven history of efficacy. It is noted especially for its effect as a tranquilliser and nerve stimulant and calming effect, particularly for those people suffering from nervous overstrain. Valerian has been shown to encourage sleep, improve sleep quality and reduce blood pressure. It is also used internally in the treatment of painful menstruation, cramps, hypertension, irritable bowel syndrome etc. It should not be prescribed for patients with liver problems. Externally, it is used to treat eczema, ulcers and minor injuries.

The root is antispasmodic, hypnotic, sedative, stimulant, urine-inducing, and has agents that relieve and remove gas from the digestive system, and powerful agents that affect, strengthen, or calm the nerves. The active ingredients are called valepotriates, research has confirmed that these have a calming effect on agitated people, but are also a stimulant in cases of fatigue. The roots of 2 year old plants are harvested in the autumn once the leaves have died down and are used fresh or dried. The fresh root is about 3 times as effective as roots dried at 40° C, whilst temperatures above 82° C destroy the active principle in the root. Use with caution, see the notes above on toxicity.

Other Uses:
The dried root has been used as an incense.
