Fucus Complex is a low-dilution homeopathic preparation of Fucus vesiculosus, Badiaga and Spongia tosta synergistically formulated to assist with thyroid insufficiency. Research indicates that following illness, glandular function is disturbed, in particular the thyroid gland, which regulates metabolism. Clinical manifestations of thyroid insufficiency include low metabolic rate, poor resistance to cold, fatigue, impaired cognition, depression and tendency to gain weight. Thyroid dysfunction causes damage to the immune system, leading to increased susceptibility to illnesses. Fucus Complex is indicated for all symptoms related to thyroid insufficiency or following a thyroidectomy, and for restoring health to the immune and glandular systems, specifically the thyroid and adrenal glands.
