The time to show the effect of the poultice needs to be decided according to the severity of the condition to be regulated and the physique of the person to be regulated, etc. Therefore, there is no standardized time for how long to take the poultice to show the effect in general. However, those who have not relieved or aggravated their symptoms after 2 weeks of medication should consult a doctor in time. Commonly used clinical creams include Erdong Cream and Ten Fragrant Warm Navel Cream. Erdong Cream has the effect of nourishing yin and moisturizing the lungs (nourishing the lungs by replenishing the fluid in the lungs). It is used for dry cough with little sputum and dry nose and sore throat caused by deficiency of lung yin. Ten Incense Warming Cord Cream is used for cold pain in the epigastrium (feeling cold pain in the stomach and abdomen) caused by deficiency of spleen and kidney, abdominal distension and diarrhea, lumbar pain and cold hernia, and cold uterine discharge. If there is any discomfort you should go to the hospital in time, you can use the ointment under the guidance of the doctor for treatment.
