What kind of food can tonify the kidneys and replenish essence?

Patient's question:

Patient Gender: Female
Patient Age: 34
I used to masturbate frequently, but now I have impotence and often experience lower back pain, backache, and fatigue.
History of Treatment and Effectiveness: I went to the hospital, and the doctor prescribed Liuwei Dihuang Pill and Zhuangyao Shenkang Pill. After taking them, things are still the same.

Doctor's answer:

Hello, medicine is not as good as food. It is recommended to eat more beans, nuts, and animal liver in daily life, and reduce sexual activity, get more rest, and increase sleep.
