The best time to take the cream formula is about 3 months between the winter solstice (December 22) and the next lunar spring. In the first week, take one tablespoon (about 30 grams) once a day in the morning on an empty stomach, and in the second week, take one tablespoon (about 30 grams) twice a day in the morning on an empty stomach and in the evening before bedtime. During the period of taking the cream, avoid eating radish, mung bean and spicy stimulating food, and avoid cold food. Do not drink with strong tea and coffee. In case of cold, fever, acute vomiting and diarrhea, stop using the formula temporarily. Patients with deficient spleen and stomach function and poor digestion should take “open road medicine” for 1 to 2 weeks to regulate the spleen and stomach before taking the cream.
