Hyperthyroid Symptoms | Anxiety, Palpitations & Tremor
Hyperthyroidism / Overactive Thyroid
Bugleweed is rich in the phenolic compounds rosmarinic acid, caffeic acid, lithospermic and chlorogenic acids. These compounds may have an antithyroid effect and have been used historically to relieve hyperthyroid symptoms.
Recent research has suggested that Rosmarinic acid slows down the way thyroid-stimulating hormone (TSH) stimulates thyroid cells by stopping adenylate cyclase. Rosmarinic acid was shown to form loose bonds with TSH, making it less likely to activate thyroid receptors and produce thyroid hormones. As a result, Bugleweed may calm an overactive thyroid, and relieve the symptoms of Grave's disease and autoimmune thyroiditis.
One human clinical study examined Bugleweed (Lycopus europaeus) and its effects on the thyroid hormones tri-iodothyronine (T3) and thyroxine (T4) in people with hyperthyroidism. The researchers concluded that the patients in the study who took Bugleweed for three months had reduced urinary T4 compared to the control group. The thyroid hormone reduction may have resulted from Bugleweed reducing the reabsorption of T4 via the kidneys.
In another clinical cohort study, groups of hyperthyroid patients who used Bugleweed extracts for various amounts of time were compared to a placebo group of hyperthyroid patients. The group who received Bugleweed (Lycopus europaeus) reported statistically significant improvement in hyperthyroid symptoms such as heart palpitations, tachycardia, tremor, and anxiety.
