According to your age and gender, if your body is normal, I suggest that you don't put angelica and licorice, just make tea with red dates, chrysanthemums and medlar, and add a little rock sugar. If you particularly emphasize the role of improving eyesight, you can also add some cassia seeds. Because medlar itself has the function of improving eyesight, so does cassia seed. But cassia seed also has the function of lowering blood pressure and relaxing bowels, so if your stomach is normal, cassia seed should not be soaked often, and it is ok to put some occasionally.

Angelica sinensis has the effects of regulating blood, nourishing blood and promoting blood circulation. Do not use it if it is not anemia or normal endocrine.

Glycyrrhiza uralensis Fisch generally treats cough, gastric ulcer, oral ulcer, ileitis and intestinal leakage syndrome. It also promotes blood circulation. Eating too much will lead to nosebleeds. Do not use it without inflammation.

Just try it.
