Male nails can reflect male sexual function
For men, kidney deficiency is not a good omen, and what's more troublesome is that the early symptoms of kidney deficiency are not obvious. According to a sex update released by the World Health Organization earlier this year, 80% of people with kidney deficiency will find white spots on their nails in the early stages.
In modern medicine, nails, located at the end of the human body and rich in microvessels and nerve endings, are important places to observe the precursors of many diseases. In traditional Chinese medicine, the kidney represents the energy storage of the human body, while the liver represents the output of energy. In traditional Chinese medicine, it is believed that the essence of the liver lies in its claws, while "liver kidney homology" refers to the fact that only a rich reserve can provide a source of backup supply.
The nails are located at the end of the human body, with a glossy and moist surface. The red and white areas above the half lunar scar faintly indicate that qi and blood can fully flow to the ends. If there is black stasis, it indicates that the meridians at the ends are already blocked.
Nail pallor is a common manifestation of insufficient qi and blood, which is the inability of our body to maintain normal peripheral vascular microcirculation. The five fingers also have their own meanings.
The little finger corresponds to the kidney, and if the color of the little finger is pale, with white spots, or even dry, it indicates kidney qi deficiency. And this is something that big families often overlook, mostly thinking that sweating and low libido are considered kidney deficiency, and it was already severe at that time.
