Need Help with Your Restless Nights.....Let Me Introduce you to Valerian

Overview: Valerian has been used to ease insomnia, anxiety, and nervous restlessness since the second century A.D. It became popular in Europe in the 17th century. It has also been suggested to treat stomach cramps. Some research -- though not all -- does suggest that valerian may help some people with insomnia. Germany's Commission E approved valerian as an effective mild sedative and the United States Food and Drug Administration listed valerian as "Generally Recognized As Safe" (GRAS). Scientists aren't sure how valerian works, but they believe it increases the amount of a chemical called gamma aminobutyric acid (GABA) in the brain. GABA helps regulate nerve cells and has a calming effect on anxiety. Drugs such as alprazolam (Xanax) and diazepam (Valium) also work by increasing the amount of GABA in the brain. Researchers think valerian may have a similar, but weaker effect. Insomnia Valerian is a popular alternative to prescription medications for sleep problems because it is considered to be both safe and gentle. Some studies show that it helps people fall asleep faster and feel that they have better quality sleep. One of the best designed studies found that valerian was no more effective than placebo for 14 days, but by 28 days valerian greatly improved sleep for those who were taking it. Some researchers now think you may need to take valerian for a few weeks before it begins to work. However, in another study, valerian was more effective than placebo almost immediately. Other studies show that valerian reduces the time it takes to fall asleep and improves the quality of sleep itself. Unlike many prescription sleeping pills, valerian may have fewer side effects, such as morning drowsiness. But not every study has found that valerian had a positive effect. One review of several studies found that valerian probably doesn' t work to treat insomnia. So the evidence remains contradictory, until more studies are done. Valerian is often combined with other sedating herbs, such as hops (Humulus lupulus) and lemon balm (Melissa officianalis), to treat insomnia. Plant Description: Valerian is a perennial plant that is native to Europe and grows up to 2 feet tall. It is grown to decorate gardens but also grows wild in damp grasslands. Straight, hollow stems are topped by umbrella-like heads. Its dark green leaves are pointed at the tip and hairy underneath. Small, sweet-smelling white, light purple or pink flowers bloom in June. The root is light grayish brown and has little odor when fresh. What's It Made Of?: The root of the plant is used as medicine and is pressed into fresh juice or freeze-dried to form powder. Available Forms: Valerian fluid extracts and tinctures are sold in alcohol or alcohol-free (glycerite) bases. Powdered valerian is available in capsule, tablet form, and as a tea. Valerian root has a sharp odor. It is often combined with other calming herbs, including passionflower (Passiflora incarnata), hops (Humulus lupulus), lemon balm (Melissa officinalis), skullcap (Scutellaria lateriflora), and kava (Piper methysticum) to mask the scent. Kava, however, has been associated with liver damage, so avoid it. How to Take It: Valerian is often standardized to contain 0.3 - 0.8% valerenic or valeric acid, although researchers aren't sure that those are the active ingredients. Pediatric Don' t give valerian to a child without first talking to your doctor. Adult For insomnia, valerian may be taken 1 - 2 hours before bedtime, or up to 3 times in the course of the day, with the last dose near bedtime. It may take a few weeks before the effects are felt. Tea: Pour 1 cup boiling water over 1 teaspoonful (2 - 3 g) of dried root, steep 5 - 10 minutes. Tincture (1:5): 1 - 1 1/2 tsp (4 - 6 mL) Fluid extract (1:1): 1/2 - 1 tsp (1 - 2 mL) Dry powdered extract (4:1): 250 - 600 mg For anxiety, 200 mg 3 - 4 times per day Once sleep improves, keep taking valerian for 2 - 6 weeks. Precautions: The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, can trigger side effects and can interact with other herbs, supplements, or medications. For these reasons, you should take herbs with care, under the supervision of a health care provider. Valerian is generally regarded as safe. Most studies show no harmful effects on fertility or fetal development, but more research is needed. Experts advise pregnant and nursing women to avoid taking valerian. Some people may have a "paradoxical reaction" to valerian, feeling anxious and restless after taking it instead of calm and sleepy. For most people, valerian does not appear to cause dependency. Nor does it cause withdrawal symptoms for most. But there are a few reports of withdrawal symptoms when valerian has been used over very long periods of time. If you want to stop taking valerian, lower your dose gradually rather than stopping all at once. Don' t use valerian while driving, operating heavy machinery, or doing other things that require you to be alert. Don' t use valerian for longer than 1 month without your health care provider's approval. Possible Interactions: If you are currently being treated with any of the following medications, you should not use valerian without talking to your health care provider. Medications broken down by the liver -- Valerian may slow down how quickly certain drugs are broken down by the liver. Many medications rely on the liver to break them down, so it' s possible that in some cases too much of these drugs could build up in the body. To be safe, ask your doctor before taking valerian if you are also taking any other medications. Sedatives -- Valerian can increase the effect of these drugs, including: Anticonvulsants, such as phenytoin (Dilantin) and valproic acid (Depakote) Barbiturates Benzodiazepines, such as alprazolam (Xanax) and diazepam (Valium) Drugs to treat insomnia, such as zolpidem (Ambien), zaleplon (Sonata), eszopiclone (Lunesta), and ramelteon (Rozerem) Tricyclic antidepressants, such as amitriptyline (Elavil) Alcohol The same is true of other herbs with a sedating effect, such as chamomile, lemon balm, and catnip. Other drugs -- Because valerian is broken down by certain liver enzymes, it may interact with other drugs that are broken down by the same enzymes. Those drugs may include: Antihistamines Statins, taken for high cholesterol Some antifungal drugs Anesthesia -- Valerian may increase the effects of anesthesia. If you are having surgery, it is important to tell your doctors, especially your surgeon and anesthesiologist, that you are taking valerian. The doctors may recommend you slowly lower the dose of valerian before surgery. Or, they may allow you to use valerian up to the time of surgery, making any needed adjustments to the anesthesia.
