Professor CUI Yun believes that in winter， all things lie dormant， and in accordance with the seasons， tonic medicines are most easily absorbed by the body. Therefore， tonic medicinal preparations， such as ointment prescriptions， are best taken in winter. The use of ointment prescriptions in treating male diseases can achieve the goals of "preserving vitality， nourishing semen， regulating constitution， preventing minor issues from escalating， and treating both the symptoms and the root cause". The characteristics of ointment prescriptions in the treatment of male diseases include emphasizing the importance of qi and blood， as well as the liver and kidneys， while also paying attention to flexibility and safeguarding the spleen and stomach.
