Wood Betony (Stachys officinalis) has a long history in traditional herbalism for nervous system support. People turn to it for mild calming effects and clearer thinking, not sedation. A cup of tea or a few drops of tincture before bed can encourage restful sleep. Many use it during stressful stretches of the day as well.
If you are pregnant or breastfeeding, steer clear. Anyone with a bleeding disorder or who takes sedatives or blood pressure medication should talk to a healthcare provider before using Wood Betony.
