Ginger is a mild aphrodisiac, and this frequently indicates that an herb targets the
Kidneys (becaused the Kidneys exercise so much influence over libido).


(Kidney Yin Deficiency may manifest as excessive physical desire; Kidney
Yang Deficiency may manifest as below normal sexual desire.)

 In any event, it definitely targets the Spleen and Stomach and helps digestion. Why can
this be so important in cases of Yang Deficiency? Because these can be snowballing situations. Cold damages the Kidneys (and the Spleen also is somewhat vulnerable to Cold). The Spleen is the system responsible for
extracting Qi from the food you eat. Part of that Qi becomes Protective Qi. Protective Qi guards the body from Exterior Pernicious Evils, including Cold. If the Protective Qi is Deficient, it's more likely that Exterior
Cold can invade and further damage the Kidneys and Spleen. The Exterior Cold is added to the Deficiency Cold. Cold also damages Yang.
