How to Preserve Essence and Strengthen Kidney
Preserving essence and strengthening kidney is a hallmark of Chinese sexual health care, a primary method of nurturing essence. Here, essence refers not only to reproductive essence but also to the essence of the five zang organs.
There are many methods for preserving essence in sexual health care. Works such as "Qianjin Yaofang" and "Yixin Fang" have proposed the "more work, less leakage" method. During intercourse, both partners should try to prolong the duration, frequently move the sexual organs, while trying to avoid premature ejaculation. Ancient medical texts believe that if the penis moves 10 times inside the vagina without ejaculating, it can make the ears and eyes sharp; reaching 20 times can make the voice strong; 30 times can make the skin smooth; 40 times can strengthen the spine and sides; 50 times can make the buttocks and thighs thick and strong; 60 times can ensure proper fluid metabolism; 70 times can enhance reproductive function and make the penis erect; 80 times can strengthen the skin and improve defensive functions; 90 times can make the spirit full and thinking agile; 100 times can maintain life and extend longevity.
The "Dongxuanzi" and other books introduced methods to prolong intercourse and delay ejaculation. It is believed that when a man feels the urge to ejaculate during intercourse, he should withdraw the penis to about one-third outside the vagina, stop moving, close his eyes, enter a meditative state, touch the tip of his tongue to the lower jaw, lift his spine, raise his head, widen his nostrils, pull his shoulders inward, close his mouth, and take a deep breath. When the urge disappears, continue moving the penis. Repeating this process can prolong intercourse. The "Yufang Zhiyao" says that just before climax, when feeling the urge to ejaculate, immediately tilt the head upward, open the eyes wide, look around in all directions, withdraw the penis from the vagina, take a deep breath, and this will help control ejaculation. Another method is to press the perineum (the area between the anus and scrotum) with the index and middle fingers of the left hand when feeling the urge to ejaculate, breathe deeply, and gently tap the upper and lower teeth together. This temporarily makes the penis soft, allowing further movement and delaying ejaculation. These methods essentially use a combination of body movements, breathing, and mental focus to delay orgasm and control ejaculation. They are often effective in treating premature ejaculation.
During the Ming Dynasty, physician Yue Fujia said: "Nowadays, those who talk about health care often say 'steal yin to supplement yang, fight long without ejaculation,' which is a great mistake. The kidney is the residence of essence. Every time male and female engage in intercourse, the kidney is disturbed. Once the kidney is active, essence follows and flows out. Even if there is no visible ejaculation, essence has already left the residence. Even if someone can hold it, there will still be a few drops of true essence leaking out along with the weakening of yang. This is proof." He introduced five methods for preserving essence: first, moderation in sexual desire to conserve blood and essence; second, avoiding fatigue, as excessive tiredness easily depletes blood and essence; third, regulating emotions, avoiding extremes of joy and anger, maintaining a calm mind to prevent disruption of qi and hidden loss of essence; fourth, abstaining from alcohol, because if alcohol is consumed excessively, being spicy and sweet, it generates heat and dampness, which combine to deplete qi and blood; fifth, adjusting diet, avoiding greasy, fried, rich, and heavy foods; instead, eat light, fresh, nutritious, and delicious meals.
Thus, moderation in sexual desire, balancing work and rest, regulating emotions, and harmonizing diet form the foundation of preserving essence and strengthening the kidney. When combined with herbal medicine, acupuncture, qigong, and massage, these practices can significantly enhance their effectiveness.
