Although coriander is delicious, it should not be eaten more or often. This is because Chinese medicine believes that coriander is pungent and fragrant, which has the effect of warming the middle warmer and strengthening the stomach. However, because coriander is pungent and can be dispersed, eating too much or for a long time will consume gas and hurt the spirit, leading to or aggravating qi deficiency. For those patients with qi deficiency who are usually sweating, fatigue, burnout and easy to catch a cold, eat less parsley. Patients who recover after childbirth and illness often have different degrees of qi deficiency. At this time, they should also keep their distance from coriander for the time being. In addition, coriander also has the function of warming sores. Patients with body odor, bad breath, gastric ulcer, beriberi and sores should not eat it, otherwise it will aggravate the condition.
