What medication should be taken for deficiency of both kidney yin and yang?
Disease description:
Lately, I have been feeling physically unwell and often fatigued. The doctor said it is an issue of kidney yin deficiency. I am curious, what medications are recommended for deficiency of both kidney yin and yang?

Kidney Yin and Yang deficiency usually presents with symptoms such as soreness and weakness of the waist and knees, cold intolerance with cold limbs, frequent nocturnal urination, dizziness, tinnitus, insomnia, and forgetfulness. Commonly used patent Chinese medicines are listed below; however, please use them under the guidance of a physician:
1. Liu Wei Di Huang Wan: Suitable for predominant Kidney Yin deficiency accompanied by symptoms such as tidal fever, night sweats, and five-palm heat.
2. Jin Kui Shen Qi Wan: Suitable for severe Kidney Yang deficiency accompanied by cold pain in the waist and knees, and impaired urination, aiming to warm and tonify Kidney Yang.
3. He Che Da Zao Wan: Suitable for Kidney Yin deficiency complicated with simultaneous Lung and Kidney involvement, such as cough and shortness of breath.
4. You Gui Wan: Mainly warms and tonifies Kidney Yang, suitable for Kidney Yang deficiency complicated with deficiency of essence and blood.
Each individual has a different constitution, and medication should be individualized; self-purchasing medications is not recommended. Additionally, improving lifestyle habits, such as engaging in appropriate exercise, maintaining regular作息 (作息 means作息 time or rest patterns, but it's better to use the English equivalent), and following a balanced diet also helps in regulating kidney function.
