Are cold hands and feet a manifestation of kidney deficiency

Cold hands and feet are not necessarily caused by kidney deficiency, but people with kidney deficiency can cause cold hands and feet due to excessive depletion of yang qi in the body and inability to contain yin qi. It is recommended to eat hot foods such as mutton and leek in the near future, and match them with cinnamon, pilose antler and other traditional Chinese medicines with good nourishing kidney yang effect for conditioning.
