Regulation of qi

"Regulation of qi" (Li Qi) is a fundamental therapeutic principle in Traditional Chinese Medicine (TCM) rather than a defined molecular target, such as a receptor or enzyme. It refers to the physiological and pathological process of ensuring the smooth flow and proper distribution of "Qi," or vital energy, throughout the body's meridians and organ systems (Zang-fu). According to TCM theory, the stagnation of Qi is a primary cause of pain, distension, and emotional disharmony. Herbs categorized as Qi-regulators are utilized to treat these conditions by promoting circulation and resolving energetic blockages. While modern research has attempted to map these effects to specific biological pathways—such as the regulation of gastrointestinal hormones, modulation of the HPA axis, or adjustments in neurotransmitter levels—the term remains a holistic functional concept rather than a singular biochemical entity. Consequently, it does not possess a canonical molecular structure or a specific entry in protein databases like UniProt.

In Traditional Chinese Medicine (TCM), the mechanism involves promoting the smooth movement of vital energy (Qi) to resolve stagnation and restore organ function. Modern pharmacological studies of Qi-regulating herbs suggest actions on gastrointestinal motility, the autonomic nervous system, and the neuro-endocrine-immune network.
