Bugleweed: Snapshot


Bugleweed reduces the activity of iodine, the activity of an overactive thyroid, and blood levels of thyroid hormones. It also lessens mucus discharge and contracts tissue to a more firm, solid state. It quiets the pulse, calms the spirit, and increases the strength of the heartbeat.
