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 them, and their condition not only does not improve, but also gradually worsens, what is the reason for this? The treatment of impotence in Chinese medicine is based on dialectical evidence to decide 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 eat more spicy, fatty and sweet products and stay up late at night, so it is less common to see people with true Yang deficiency, but more common to see people with 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, so 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 have curled branches and leaves because of drought, if the fire is added to roast, the plant will be 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 pouring oil on the fire, the stronger the yang, the more impotent . Therefore, it is recommended that: impotent people should not use aphrodisiacs indiscriminately, but should apply them reasonably under the guidance of an herbalist.
