Valerian is another great herb that's used as a sedative. Valerian (Valeriana officinalis) soothes anxiety and is often used as a sleep aid. Commonly doubled up with California poppy, it makes a powerful, but gentle sedative. Valerian can interact with medications and shouldn't be used without first checking with your doctor. Pregnant and lactating women shouldn't take valerian.
