Valerian in known for its calming properties, soothing anxiety and balancing moods. We have a lot of valerian growng in our garden and I can verify that I never feel anything but calm out there. Of course we also regularly have seven Jimley Jackdaws on the bird table, a bunch of silly chickens, sunbathing dogs and a small child showing an unreasonable amount of talent at kicking a ball. What's to worry about?
