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 nervine, particularly for those people suffering from nervous overstrain[4, 222]. Valerian has been shown to encourage sleep, improve sleep quality and reduce blood pressure[254]. It is also used internally in the treatment of painful menstruation, cramps, hypertension, irritable bowel syndrome etc[238, 254]. It should not be prescribed for patients with liver problems[238]. Externally, it is used to treat eczema, ulcers and minor injuries[238]. The root is antispasmodic, carminative, diuretic, hypnotic, powerfully nervine, sedative and stimulant[4, 7, 9, 14, 21, 46, 147, 165, 192, 218]. 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[222]. The roots of 2 year old plants are harvested in the autumn once the leaves have died down and are used fresh or dried[4, 9, 238]. The fresh root is about 3 times as effective as roots dried at 40° (the report does not specify if this is centigrade or fahrenheit), whilst temperatures above 82° destroy the active principle in the root[240]. Use with caution[21, 238], see the notes above on toxicity.

The plant yields about 1% of an essential oil from the roots[7, 238]. It is used in perfumery to provide a 'mossy' aroma[57, 61, 238], though the scent is considered to be disagreeable by many people[207]. The dried roots are also placed in linen cupboards and clothes drawers in order to scent the clothes[4]. The dried root attracts rats and cats, it can be used as a bait to lure them away from other areas[100]. An ingredient of 'QR' herbal compost activator[32]. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost[K]. The plant can also be used to make a very good liquid plant feed[14, 18, 201]. It attracts earthworms[14, 18]. The leaves are very rich in phosphorus[201].
