Kidney and Spleen Yang deficiency herbs

What would you recommend for this condition, herbally?

• Bu Zhong Yi Qi?
• Jin Gui Shen Qi?
• Both or just one of them?
• Something else

How do they interact - if you take one does it make the other redundant?

Which is stronger for boosting energy when you have SP yang dx (low appetite, fatigue) and KD yang dx (cold, fatigue, low libido)?

-see a practitioner - yes I have done, looking for other opinions.
