Have you experienced dialectical treatment of impotence by drinking Xuefu Zhuyu Decoction? Don't see someone who drinks it and it is effective. They must have gone through dialectics of traditional Chinese medicine. Not every person can be cured, the constitution and cause of the disease are not the same, or different people can be treated by adding or subtracting from this prescription, or different prescriptions, in short, dialectical treatment is needed to be effective.
