Herbs and foods to regulate and take care of the thyroid

The thyroid is a butterfly-shaped endocrine gland that is located in the neck, above the collarbone. It is responsible for controlling metabolism, body temperature and the processing of calories.

When the level of thyroid hormones is abnormal, certain health problems can occur. Fortunately, there are herbs and foods that help regulate it. Find out here what the best options are.

What role does the thyroid play?

The thyroid gland produces, stores and releases two hormones: T4 (thyroxine) and T3 (triiodothyronine), responsible for controlling metabolism. When the thyroid is working properly, the body maintains a constant rhythm, that is, neither too fast nor too slow.

These hormones take effect slowly and affect many processes, such as growth and development, obtaining energy from food, sexual function, reproduction, and even mood.

The thyroid, in turn, is controlled by the pituitary gland (which is located in the brain). This is responsible for making the thyroid-stimulating hormone (abbreviated in English, TSH), which tells you how much hormone production is necessary.

When there is not enough thyroid hormone in the blood, the rate of metabolism slows down, a condition known as hypothyroidism (underactive thyroid). Its symptoms appear slowly, that is, you could have the disease and not have any discomfort for months or years.

Its main symptoms are: weakness, weight gain, lack of appetite, change in menstrual periods, low sexual desire, feeling cold, constipation, muscle aches, swelling around the eyes, brittle nails and hair loss.

On the other hand, if there is too much thyroid hormone in the blood, the metabolism speeds up, which is known as hyperthyroidism (overactive thyroid).

Among its most common signs are: exhaustion, weight loss, nervousness, rapid heartbeat, increased sweating, feeling hot when others do not feel it, change in menstrual periods, more frequent bowel movements, tremors and bulging eyes.

The researchers maintain that this may be due to the fact that its active ingredients are capable of reducing excess inflammation and optimizing hormonal release to avoid complications.


The valerian officinalispopularly called valerian, is a plant whose rhizomes, roots and stolons are used for their sedative properties.

There is scientific evidence that links its consumption with a greater relaxation of the nervous system, helping to control sleep problems that occur as a result of the symptoms of hypo- and hyperthyroidism.

Grass of San Juan

St. John’s wort, also called hypericum or little heart, is a plant associated with the treatment of symptoms of hypothyroidism, tiredness, lack of energy, decay and depression.

Cruciferous vegetables (broccoli, cabbage, Brussels sprouts, radishes, and cauliflower) are recommended to control hyperthyroidism, although they can be counterproductive for hypothyroidism. This is due to the presence of compounds called goitrogens, which interfere with the production of thyroid hormones.

See your doctor about your thyroid

To diagnose thyroid disease, doctors use a medical history, a physical exam, and tests for the thyroid, and in some cases, they may choose a biopsy.

Treatment will depend on the problem that caused the hyper or hypothyroidism, but usually includes medications, radioactive iodine therapy, or thyroid surgery.

To remind:

Until there is meaningful scientific evidence from human trials, people interested in using herbal therapies and supplements should be very careful.

Do not abandon or modify your medications or treatments, talk to your doctor first about the potential effects of alternative or complementary therapies.

Remember, the medicinal properties of herbs and supplements can also interact with prescription drugs, other herbs and supplements, and even alter your diet.
