Patients who drink Chinese medicine and show symptoms of headache, confusion and nausea should first consider that it is caused by medication, because there are many ingredients in Chinese medicine such as worm medicine that can cause some stimulation to the patient’s stomach and lead to the problem of nausea. There is also the question of whether the patient originally had a headache. Drinking herbal medicine, a stimulating smelling liquid, may also cause discomfort in the body, manifesting as headache, confusion and nausea. If it is clear that it is caused by drinking Chinese medicine, it is recommended that the patient stop the Chinese medicine and then observe the condition and drink more water to expel the medicine from the body. It is important to consult the doctor who prescribed the Chinese medicine in time to clarify whether it is because of certain sensitive ingredients in the medicine that cause the patient to have an allergic reaction, give timely feedback to the doctor, and then seek solutions to the problem.
