People with an abnormally high rate of metabolism tend to be extremely thin, have difficulty putting on weight and may experience palpitations, heat intolerance, nervousness, insomnia, breathlessness and muscle weakness. High metabolism is generally associated with an overactive thyroid function, a condition known as hyperthyroidism. Some herbs appear to be effective in slowing down metabolism. However, consult with a medical professional before beginning any regimen of self-treatment.
Ayurvedic Herbal Remedies
Ayurveda is a system of traditional medicine that developed on the Indian subcontinent and continues in wide use there and elsewhere around the world. Practitioners of Ayurvedic medicine classify all herbs and vegetables as either hot or cold, according to Karta Purkh Singh Khalsa, author of "Body Balance." Garlic, for example, is classified as hot, while typical salad vegetables are considered cold. While hot foods and herbs increase metabolism and appetite and improve circulation, cooling substances slow down metabolic rate while also combating inflammation and reducing fever. Khalsa singles out dandelion and sandalwood oil as two herbal remedies that can help to slow down metabolism and resolve the symptoms associated with the condition. Check with your doctor before taking these or any other herbal remedies.
Green Tea and Lemon Balm
In its overview of alternative and complementary therapies used in the treatment of hyperthyroidism, the University of Maryland Medical Center identifies green tea and lemon balm as widely used herbal remedies for this condition. "Herbs are generally a safe way to strengthen and tone the body's systems," the center observes, but it cautions that these or any other herbs should not be taken until you've consulted with a medical professional. UMMC recommends a daily dose of 250 to 500mg of standardized green tea extract. Lemon balm can be taken in capsule form--300 to 500 mg three times daily--or as a tea. To make the latter, steep 2 tbsp. of dried lemon balm in 1 cup of boiling water for 10 to 15 minutes. Strain and allow to cool before drinking.
Bugleweed
Botanist James A. Duke, author of "The Green Pharmacy Herbal Handbook," reports that bugleweed, or Lycopus virginiana, is widely used in Europe for the treatment of early-stage Graves' disease, a form of hyperthyroidism. The herb slows down the metabolism of iodine, thus reducing the amount of hormone produced by the cells of the thyroid gland. Duke cautions, however, that the effect of bugleweed is relatively mild and probably most useful in treating mild cases of hyperthyroidism. Asa Hershoff and Andrea Rotelli, authors of "Herbal Remedies," also recommend bugleweed as a treatment for hyperthyroidism, as well as enlarged thyroid. They note that the herb is particularly effective in reducing palpitations and easing chest tightness.
