The theory of traditional Chinese medicine is one of the treasures of the Chinese nation, and its essence lies in the idea of "harmony between heaven and man". The theory of traditional Chinese medicine emphasizes the harmonious relationship between humans and nature, believing that all living organisms in nature have their unique patterns and ways of life activities, and that humans should comply with nature and coexist harmoniously with it.
Traditional Chinese medicine theory believes that the balance of qi, blood, yin, and yang within the human body is the foundation of health. When the imbalance of qi, blood, yin, and yang within the human body occurs, it can lead to the occurrence of various diseases. Therefore, the main method of traditional Chinese medicine treatment is to regulate the balance of qi, blood, yin, and yang within the human body, in order to achieve the goal of treating diseases.
In addition, the theory of traditional Chinese medicine also emphasizes the principle of "supplementing the organs with the organs". It is believed that the five organs and six organs of animals can correspond to the five organs and six organs of the human body, so consuming the five organs and six organs of animals can benefit the corresponding organs of the human body. For example, pig liver can nourish the liver of the human body, while pig waist can nourish the kidneys of the human body, and so on.
中药理论是中华民族的瑰宝之一，其精髓在于“天人合一”的思想。中药理论强调人与自然的和谐关系，认为自然界中的一切生物都有其独特的生命活动规律和方式，人类应该顺应自然，与自然和谐共处。

中药理论认为，人体内部的气血阴阳平衡是健康的基础。当人体内部的气血阴阳失衡时，就会导致各种疾病的发生。因此，中药治疗的方法主要是通过调节人体内部的气血阴阳平衡，达到治疗疾病的目的。

此外，中药理论还强调“以脏补脏”的原则。认为动物的五脏六腑可以对应人体的五脏六腑，因此食用动物的五脏六腑可以补益人体的相应器官。例如，猪肝可以补益人体的肝脏，猪腰可以补益人体的肾脏等等。
