Of course, lavender also makes the list of best bath herbs. Who doesn’t enjoy a soothing soak in lavender-scented waters? Perfect for any type of bath, lavender is a wonderful supporting player to include in most herbal blends. Use it to relax at the end of a long day. Lavender works as an anxiolytic (an anxiety reliever) and as a sedative, to increase relaxation and calm, and help bring about sleep. Lavender interacts with the neurotransmitter GABA to help quiet the brain and nervous system activity, reducing agitation, anger, aggression, and restlessness.
