Hyperthyroidism belongs to the category of “gall disease” in traditional Chinese medicine, and saffron belongs to the category of drugs that can activate blood circulation and remove blood stasis, and will not affect the secretion of thyroid hormones, so hyperthyroid patients can drink saffron. Hyperthyroidism is a disease of hypermetabolism caused by excessive secretion of thyroid hormones by the thyroid gland, which is manifested by symptoms such as excessive sweating, panic, thinness, easy hunger and insomnia. Saffron is sweet in flavor and flat in nature. It belongs to heart and liver meridians. It has the effects of activating blood circulation and removing blood stasis (promoting blood circulation and eliminating blood stasis in the body), cooling the blood and removing toxins (referring to the treatment of blood-heat and toxins in the body), relieving depression and tranquilizing the mind. It is used for treating menstrual obstruction and impediment (lumps in the lower abdomen of women), post-partum stasis, warm-heat and poisonous spots (warm-heat and poisonous evils invading the body resulting in blotches and patches on the skin), melancholic ruffling, and palpitations and frenzy. The use of Chinese medicines needs to be guided by a doctor, do not take medicines on your own.
