Spleen and kidney yang deficiency (deficiency of yang qi in the spleen and kidneys) can lead to cold-damp congestion, which in turn can aggravate spleen and kidney yang deficiency. According to Chinese medicine, the spleen is the main transporter (the spleen has the function of digesting food, absorbing food essence and water and transferring it to the whole body), transporting and transforming the essence of water grains and water to the whole body; and the kidneys are the main water transporter, which means that the warming and promoting effect of the kidneys can regulate the metabolism of the body’s fluids and fluids. If the spleen and kidney yang is weak, the spleen’s ability to transport and transform water and grain essence and water is weakened, the warmth and promotion of the kidney is weakened, resulting in stagnation of the body’s water and fluid, the formation of cold and damp congestion of the evidence. In turn, the longer the cold dampness stays in the body, the more the yang of the spleen and kidneys will be depleted; and cold dampness can also block the yang of the spleen and kidneys from running through the channels in the body, and the yang of the spleen and kidneys can not be widely distributed throughout the whole body, which will lead to an increase in the degree of yang deficiency of the spleen and kidneys. Therefore, cold and dampness congestion and spleen and kidney yang deficiency interact with each other and influence each other.
