Regarding thyroid and total cholesterol in the three groups of mice, the results showed an increase in TSH in the group given propylthiouracil, while ginger appeared to reduce blood lipids and cholesterol caused by hypothyroidism in mice. It is necessary to reduce the side effects associated with high blood lipids until the thyroid gland is treated so that ginger does not have a direct effect on the thyroid gland.
