Caffeine and valerian appear to be unrelated substances. The former is a bitter plant-based compound known to boost alertness, while the latter is a flowering herb widely used for its relaxing, sedating effects. But according to a 2004 article in the journal "Planta Medica," they share an important commonality: Both substances appear to target the adenosine receptors in the brain, although with opposite effects. Before using caffeine or valerian for medicinal purposes, consult a qualified health care professional.
Uses for Valerian
According to naturopathic doctor Mark Stengler, author of "The Natural Physician's Healing Therapies," valerian was known as a medicinal herb for epilepsy, menstrual cramps and gastrointestinal problems by ancient Greeks and Romans and as an antianxiety and insomnia remedy by war-weary Londoners during World War II. Stengler recommends 300 to 500 mg of valerian 30 to 60 minutes before bedtime for insomnia and 300 to 500 mg up to four times daily to ease anxiety and tension. Use valerian under the supervision of a qualified health care professional.
Valerian Cautions and Considerations
Studies of valerian have shown that it is generally well tolerated and free from serious side effects, according to the Office of Dietary Supplements at the National Institutes of Health. Dizziness, itchiness and gastrointestinal upset have been occasionally reported in clinical trials. Do not use valerian in combination with alcohol or sedating drugs, as it may increase their effects. Pregnant women, nursing women and children under 3 years of age should avoid valerian, as it has not been adequately tested in those populations.
Caffeine
Caffeine's well-known ability to boost alertness is responsible for coffee's honored place at the breakfast table. According to Johns Hopkins Bayview Medical Center, caffeine is the world's most frequently consumed mood-altering drug. Low doses of caffeine in the range of 20-200 mg daily are associated with increased sociability, happiness, energetic arousal and well-being. While coffee is the best-known caffeine source, it is also present in tea, soft drinks, chocolate and some medications.
Caffeine Cautions and Considerations
Caffeine is associated with a number of health risks, according to Johns Hopkins Bayview Medical Center. In doses in excess of 250 mg, the amount present in two and a half cups of coffee, it can lead to caffeine intoxication, whose symptoms include agitation, excitement, extreme restlessness and even hallucinations. Regular caffeine use, even when it is consumed early in the day, can disrupt sleep patterns and lead to insomnia. Pregnant women should limit their caffeine use, as it may be associated with low birth weight babies. Consult your physician if you have questions about caffeine and your health concerns.
