I don't know what surgery you had, but since the doctor said you can't eat hair products, it's better not to eat coriander, because coriander also belongs to the category of hair products, and other common hair products, such as beef, mutton and seafood, can't be eaten, and be careful not to drink and smoke, otherwise it will probably affect the postoperative recovery and lead to some complications. After operation, everyone must pay attention to self-care, eat lightly and avoid bad stimulation.
