Experts point out that in daily life, many people mistake kidney deficiency for yang deficiency and believe that it is necessary to strengthen yang. In fact, yang deficiency is only one possibility, and it may also be kidney yin deficiency. "Kidney yin deficiency and kidney yang deficiency have one cold and one heat, and their symptoms, manifestations, and tonifying methods are also greatly different.". If kidney deficiency is caused by kidney yang deficiency, strengthening yang is a timely help; If you already have a deficiency cold type constitution and continue to nourish yin, such as taking Liuwei Dihuang Pill (nourishing yin), it would be like adding insult to injury.
"Kidney yin deficiency often occurs in young and middle-aged people, who have a large amount of activity and a high level of energy consumption. The main symptoms are weakness in the waist and knees, restlessness in the five hearts, dizziness and tinnitus, weight loss, insomnia and dreaminess, redness and hot flashes in the cheekbones, night sweats, dry throat, and male impotence." Experts said. Experts suggest eating sticky and slippery foods such as fish maw, snow clam paste, loach, sea cucumber, oyster, eel, and cuttlefish for dietotherapy, as well as nuts such as walnuts, almonds, chestnuts, peanuts, and wolfberry.
For those with deficiency of kidney yang, experts say it is mainly caused by factors such as aging, kidney deficiency, chronic illness, kidney injury, and excessive room strain. The common symptoms are weakness in the waist and knees, fear of cold and cold limbs, dizziness, mental lethargy, and pale or swarthy complexion. It is recommended that dietotherapy should often eat foods that are biased towards masculinity, such as seahorses, sea dragons, geckos, royal jelly, and whips.
