Nervine relaxants are milder remedies which can help calm, relax, and sedate overly excitable nervous system and "smooth out rough edges." They can oftentimes be used throughout the day to manage stress and anxiety and will not tend to make you sleepy, groggy, or very low in energy, although at heavier doses many of these herbs can act as hypnotics.
It is important to note that excessive use of relaxants can deplete and weight heavily on the whole nervous system. If you find yourself needing nervine relaxants on a daily basis, consider incorporating nervine tonics into your daily regiment to help strengthen, feed, and restore damaged nerve tissue from chronic stress and anxiety.
