Valerian is a vareous herb that grows in Asia, New England, Europe, India, Korea, China and North America. It may look like a weed, but it's health properties can be very nice. Some are calming the mind and nerves throughout the body, while others are for sleeping. It works like this: it connects with a near nerve system. Scientists don't know what makes Valerian work yet. So far, we know that in its smelly root that the props are there. It's believed to be very safe. In 1995 a woman took forty to fifty 470-mg capsules of a species of Valerian powdered root, in attempting suicide. In thirty minutes, she felt fatigue, stomach cramping and tremors in her hands and feet. The next day, they were gone. This proved that Valerian was non-toxic. If you ever take Valerian, use 300 to 400 mg capsules before bed. (Depending on the size) Or 200 to 300 in the morning.
