Symptoms: soreness and weakness of the waist and knees / tinnitus / loss of vision / spermatorrhea / hot flashes and night sweats (sweating in sleep) / five heartburn and heat / dry mouth but no desire to drink / dry eyes and red cheekbones / dizziness and dizziness / red tongue with no moss or peeling of the moss / amenorrhea and infertility in females / spermatogonium and sterility in males.

Yin deficiency produces internal heat, not really heat, but fire caused by insufficient yin that cannot control yang.

2 Kidney yang deficiency:

Symptoms: cold limbs / hands and feet cold / face white or dark / lumbar spine pain / knees cold / weakness / libido loss / impotence and premature ejaculation / urinary edema / eating less loose / tongue coating thin white / tongue pale fat tender.

The above is the difference, the two symptoms are not the same, but in real life there is rarely a single yin or yang deficiency, most of the yin and yang deficiency, this is a different proportion of the weight of the different.

"***Same point"

It must be clear, kidney Yin, kidney Yang is an abstract description of the state of the kidney, does not represent any specific thing, kidney essence this is the real existence of the yin and yang are in the kidney essence based on the division. It's like a glass of water, 20 degrees is a healthy temperature, if it is lower than 20 degrees is the kidney Yang insufficient, higher than 20 degrees is the kidney Yin insufficient, first figure out the kidney Yin, Yang represents what meaning.

Whether it's kidney yin or kidney yang, it's essentially a lack of kidney essence.

"Harm"

Whether the kidney yin or yang deficiency, long-term non-regulation, will evolve into yin and yang deficiency, because yin and yang are interdependent as a whole, like the Tai Chi pattern, a single can not be alone, the development of the final, which means that the entire kidney function will decline, perhaps the libido is all, and do not love fire, and do not have the urge to do so, and so on.
