Which approach is commonly used in traditional Chinese medicine?

The hot and cold theories are a fundamental aspect of traditional Chinese medicine (TCM), representing the concept of balancing opposing forces to maintain health. In TCM, various conditions are categorized as either "hot" or "cold," and treatment plans are developed based on this dichotomy. The idea is that maintaining balance between these two forces is essential for overall wellness. For instance, certain foods and herbs are classified into these categories, guiding practitioners in advising patients on diet and treatment to restore harmony to the body.

This contrasts with other approaches mentioned in the options, which are not core concepts of TCM. Mind-body dualism, for instance, reflects a philosophical viewpoint about the separation of mental and physical processes, rather than a practical healing method used in TCM. Similarly, genetic modification and regulatory practices pertain more to modern medical and agricultural practices than to traditional healing arts. Thus, the hot and cold theories illustrate a key principle of TCM, making it the correct choice in this context.
