Is it better to treat kidney yang deficiency with Yu Gui Wan or Gui Fu Di Huang Wan?

Both Deuqui Pill and Gui Fu Di Huang Wan can be used to treat kidney yang deficiency, but Deuqui Pill is stronger in warming and tonifying the kidney yang, so the choice of medication depends on the severity of the condition.
1. Right Angelica Pill is composed of cinnamon, Chinese yam, ripened rhubarb, cornelian cherry, cuscuta and other medicines, with the effect of warming and tonifying Kidney-Yang, filling up essence and stopping spermatorrhea (filling up and stabilizing essence, preventing spermatorrhea and semen slippage), and it can be used for the treatment of cold pain in the waist and knees, dysphoria, coldness and coldness of limbs, which are caused by insufficient Kidney-Yang and failure of the vital energy (the weakness of Kidney-Yang in the body, which reduces the functions of warming and promoting the operation of qi and blood).
The adverse effects and contraindications of this drug are not clear.
2. Gui Fu Di Huang Wan is composed of cinnamon, epimedium, danpi, yam and zedoary, etc. It has the effect of warming and tonifying kidney yang, and can be used for the treatment of cold and soreness of the waist and knees, dysuria (unruly urine), and wheezing and coughing caused by insufficiency of kidney yang.
Its adverse effects and contraindications are not clear. Avoid indigestible food while taking the medicine. It should not be taken by patients with cold and fever, and should not be used by patients with Yin deficiency and internal heat.
All of the above drugs can be used to treat kidney yang deficiency, but Yuegui Wan has a stronger effect of warming and tonifying kidney yang, so if kidney yang deficiency is more serious, it can be treated with Yuegui Wan. If medication is needed, it should be taken under the guidance of a doctor.
