Is there a natural cure for Thyroid problems?  

I think you must eat well and take a proper care of your diet like if the thyroid problem is severe it is then good to avoid brussels sprouts, cabbage, broccoli, kale, mustard greens, peaches and pears as they have anti-thyroid substances and may suppress the thyroid function. Eat foods rich in vitamin A, such as yellow vegetables, eggs, carrots, and dark green vegetables. The amino acid tyrosine is helpful. Tyrosine is found in edamame, beef, chicken, and fish. Soy should be only used in small amounts or on an occasional basis. Irish moss and kelp are used in combination to balance hormonal deficiency. They increase the metabolic rate, thyroid activity and the detoxifying function of the body, and increase blood circulation and soothe inflamed tissues. Black walnut has a high content of iodine and is a thyroid stimulant.
Ginseng strengthens the body.

I hope you get well soon.
