Valerian is a root that has long been used as an herbal sleep aid. It has a characteristic smell, like old socks, which comes from isovaleric acid. Valerian can be used to help occasional sleeplessness, but is also particularly helpful taken long-term. Many studies have shown valerian root to be an extremely safe and effective way to promote sleep. Patients who take valerian report that they feel less anxious and nervous, and have better rest at night. There are many benefits that you can get from using valerian as a sleep aid supplement. Unfortunately, not all people can have easy access to it. However, there is an alternative natural sleep aid supplement that can also do wonders for insomniacs and the name is Melatrol.
