Taking Wu Zi Diffractor Pills for Yin-Yang deficiency is not the right thing to do. Wu Zi Diffractive Zong Pills are mainly used for diseases related to kidney deficiency and essence deficiency, not for treating those with both yin and yang deficiency, so it is not suitable to take Wu Zi Diffractive Zong Pills for both yin and yang deficiency. Yin and yang deficiency refers to both yin and yang deficiencies, so it is called yin and yang deficiency. Yin and yang deficiency should be treated by tonifying both yin and yang, using treatments such as nourishing yin and warming yang and nourishing yin and strengthening yang. Wu Zi Diffractive Zong Pill is effective in tonifying the kidney and benefiting the essence (replenishing the kidney essence), and is mainly used for treating impotence and infertility caused by kidney deficiency and essence loss, spermatorrhea and premature ejaculation, lumbago, and residual leeching after urination. Its adverse effects are still unclear, and it is not recommended to be used on patients with colds and fever, and is contraindicated for those who are allergic to this product. Yin and Yang deficiency people need to take medication under the guidance of a traditional Chinese medicine practitioner, do not take blindly, so as not to damage the body and aggravate the condition.
