Vervain Herb (Verbena officinalis) is a medicinal herb popular for its calming properties. An ancient text from Egypt recommends it for the treatment of anxiety and stress. Scientific studies have confirmed the plant's ability to reduce stress levels and improve relaxation.

 Vervain was used for gum problems, sore throats and sinusitis. It seems to have a calming effect on the body and may help to ease arthritic pain. 

Perhaps this would be something to add to a cup of tea at night .
