Valerian is synthesized to make Valium but the herb itself is safe and non-addictive for epts and people.
Valerian is an antispasmodic, and nerve tonic. It allays pain and promotes sleep and is non-narcotic.
I use it to help calm pets with anxiety and over active personalities. It is a sedative and pain killer - stronger than other herbal sedatives. It soothes the nervous system and reduces high blood pressure. Valerian slows and strengthens the heart and calms palpitations.
It is useful for muscle spasms, arthritis pain, and spinal injuries. It aids digestion and gas. For people it can help promote sleep.
Cats love the smell almost like catnip - to me it smells like very stinky feet! I use the capsules to avoid the smell and sprinkle a little bit in the wet food, stirring it in.
