Modern Evidence

Bugleweed has a tradition for mild calming and, in modern herbalism, for mild overactive-thyroid symptoms; preclinical work suggests effects on thyroid hormones and heart rate. Clinical evidence is insufficient; it is not a treatment for hyperthyroidism, palpitations, or any disease, and is best used with professional guidance.
