In the population of male patients, there are more patients with impotence (known as sexual dysfunction in Western medicine). Many patients have taken aphrodisiacs according to Chinese folk experience before consulting the doctor, and their condition not only does not improve, but also gradually worsens. The treatment of impotence in Chinese medicine is based on dialectical evidence to determine the treatment plan. In ancient times, people did not have enough to eat and wear, so they had more “deficiency” and were suitable for aphrodisiacs. Nowadays, people’s standard of living has improved, they are more addicted to spicy, fatty and sweet products, and they stay up late at night more often, so they are less likely to suffer from true Yang deficiency, and more likely to suffer from Damp-Heat and Yin deficiency. Therefore, do not see impotence, then throw aphrodisiac products. For example: deer antler, deer whip, seahorse, Epimedium, Yang Qi Shi and other aphrodisiacs. The more aphrodisiacs you see, the more impotent you become. This is the time to “nourish Yin”, not “aphrodisiac”. The practice of “aphrodisiac” is now prevalent and really undesirable. It is true that warming the kidneys and aphrodisiacs is a good remedy for impotence of kidney yang deficiency. But if you do not identify the evidence, blindly aphrodisiac, often counterproductive. The Qing Dynasty medical doctors have long said: “(impotence) due to Yang deficiency less, because of the Yin deficiency more”, “true Yang injury is inherent, and true Yin injury is actually more, why can be said that impotence is true fire failure?”. . Many people who do not study Chinese medicine find it difficult to understand the doctrine of yin and yang. I will give my patients the most simple and easy to understand example: for example, a grass needs sunlight and water to thrive, sunlight is equivalent to yang and water is equivalent to yin. If there is a lack of sunlight (yang), the grass will not grow, but if there is a lack of water (yin), it will not grow; just as in a hot summer day, many plants because of drought, the branches and leaves curl and do not stretch, if you add a fire to roast, the plant is dead; such as the lack of nourishment of Yin essence, there are many uncomfortable symptoms, including impotence, if you continue to strengthen the Yang, it is the same as adding oil to the fire, the more Yang will become impotent. . Therefore, it is recommended that: impotent people should not use aphrodisiacs indiscriminately, but should be applied reasonably under the guidance of an herbalist.
