How about Yang's cream? Is it true or not?

Teacher Yang's ointment is mainly aimed at conditioning women's qi and blood, menstruation and gynecology, but it can't cure all diseases. The conditioning of qi and blood is still very good. At that time, the traditional cream had no preservatives and was completely preserved by hand for two years. I took a course of treatment and the effect was satisfactory. I am going to buy another dish for my mother.
