ABSTRACT
Bronchial asthma, a chronic inflammatory airway disease, belongs to the category of wheezing disease in the system of traditional Chinese medicine (TCM). The wheezing symptom of this disease is mainly caused by the imbalance of lung Qi. According to the theory of five flavor compatibility, the Chinese medicinal materials with five different flavors (pungent, bitter, sour, sweet, and salty) can be combined to produce new functions. The pungent medicinal materials have dispersing effect and the bitter medicinal materials have discharging effect, which are important components in the theory of five flavor compatibility. Pungent herbs and bitter herbs can relieve the adverse lung Qi, occupying an important position in the current medication for the treatment of asthma. However, there is still a lack of in-depth analysis of the TCM theory and mechanism of the compatibility of pungent herbs and bitter herbs in the treatment of asthma. The molecular mechanisms of action of pungent herbs and bitter herbs are closely related to transient receptor potential (TRP) channels and bitter taste receptors (TAS2Rs), respectively. Ca2+ signaling has been recognized in the process of asthma and is involved in the development of multiple symptoms of asthma. The TRP channels and TAS2Rs located on the cell membrane have been proved to directly regulate the intracellular Ca2+ signal and play a role in the treatment of asthma. Therefore, the dispersing effect of pungent herbs and the discharging effect of bitter herbs may be realized through the Ca2+ signaling pathway mediated by TRPs/TAS2Rs. We summarized the theoretical understanding and modern studies of pungent herbs dispersing lung Qi and bitter herbs discharging lung Qi, aiming to explain the internal relationship and mechanism of the compatibility of pungent herbs and bitter herbs in the treatment of asthma from the perspective of TCM theory and modern medicine. The compatibility of pungent herbs and bitter herbs based on the theory of five flavor compatibility for the treatment of asthma has a solid theoretical basis of TCM, and its mechanism can be verified by modern research. Therefore, it may be a main research direction in the treatment of asthma by Chinese medicinal herbs in the future.
