Yao Lan, an ancient prescription, is a Chinese herbal medicine formula, and its main components include many Chinese herbal medicines, such as Indigo edulis, Astragalus membranaceus, Lycium barbarum and so on. It has the effects of clearing away heat and toxic materials, nourishing liver and improving eyesight, nourishing yin and tonifying kidney. Health care products refer to those products that can promote health, prevent diseases or improve physical condition, such as health care products, food, drinks and so on. Therefore, the ancient Yao Lan does not belong to health care products.
