However, nourishing Yang Can is not a simple question. In the theory of traditional Chinese medicine, the relationship between Yang Qi and vulva is not a simple causal relationship. They both promote and restrict each other. Therefore, it is not feasible to achieve the purpose of nourishing yin simply by nourishing yang.
Wu Zetian's personal experience of growing new teeth is also an interesting example. According to legend, Wu Zetian once lost her teeth by taking Dan medicine for a long time. Later, she followed the advice of a Taoist priest and began to rinse her mouth with salt water every day. After a while, her teeth actually grew back. This story shows that the purpose of nourishing yin can indeed be achieved through the correct method.
In short, nourishing yang and nourishing yin are both important means of health preservation. However, we can't simply think that nourishing Yang Can is nourishing yin. We need to take appropriate measures to regulate our body according to our actual situation. At the same time, we should also pay attention to avoid excessive dependence on external factors such as drugs or health care products, but pay attention to adjusting our lifestyle and eating habits. Only in this way can we truly achieve the purpose of health preservation.
