Before over-the-counter medications were available, valerian was used by herbalists to ease pain. The valepotriates in valerian act as muscle relaxants, making it useful for painful spasms and menstrual cramps. But researchers have discovered a number of other factors responsible for valerian's relaxing, sedative and analgesic effect: valeric acid, volatile oils, choline, flavonoids, sterols, and alkaloids.
"Valerian root has been used for centuries to calm upset nerves, treat mood problems, pain, and headache. In medieval times, valerian was so popular it became known as "all-heal." It is currently one of the most popular orthodox antispasmodic medications in Russia and Germany."
