Evolutionary pathway of TCM in allergic diseases: A Fusion from ancient wisdom to modern science

Allergic diseases, including allergic rhinitis, allergic asthma, atopic dermatitis, and food allergy, today represent a major threat to global health, affecting approximately 500 million people worldwide with allergic rhinitis and 300 million with allergic asthma. These conditions are characterized by abnormal immune responses or hypersensitivity reactions triggered by exposure to sensitizing substances, resulting from an overactive immune system. The World Health Organization has classified allergic diseases as one of the three main health issues requiring urgent prevention and control in the 21st century. The continuous increase in the prevalence of these conditions, together with their heterogeneous nature, complex pathogenesis, and tendency to recur, has stimulated a growing demand for effective therapeutic strategies.

This study aimed to explore the evolutionary trajectory of Traditional Chinese Medicine in the treatment of allergic diseases, analyzing how ancient wisdom integrates with modern science. The researchers conducted a comprehensive literature review, examining the theoretical foundations of TCM for allergic diseases, including the concepts of allergic constitution, differentiation of disease patterns, and the principles of strengthening healthy qi to resist pathogenic qi. The methodology included analysis of traditional classical prescriptions and contemporary formulas, as well as non-pharmacological therapies such as acupuncture, moxibustion, massage, Chinese herbal lotions, medicinal teas, and dietary therapy. The study also investigated the molecular mechanisms by which TCM regulates various immune cells and protein gene expressions, inhibits inflammation, and alleviates allergic reactions.

The main findings revealed that TCM offers unique advantages in managing allergic diseases through its holistic and personalized approach. TCM constitution theory, particularly the concept of "allergic constitution" proposed by Wang Qi, proved fundamental for understanding individual susceptibility to allergic diseases. Classical prescriptions such as Baihu Decoction and Maxing Shigan Decoction showed superior efficacy in treating allergic conditions, while modern formulas such as GMK (Guominkang) demonstrated the ability to inhibit mast cell degranulation and modulate immunological signaling pathways. Acupuncture and moxibustion therapies at specific points such as Yingxiang, Yintang, and Baihui proved effective in regulating the neuroimmune system, inhibiting elevation of serum IgE levels and balancing pro- and anti-inflammatory cytokines.

The studies also identified that TCM acts through multiple pathways, including Th1 and Th2 cell differentiation, TLR cascade reactions, and Th17 cell differentiation, providing a more comprehensive approach than conventional treatments.

For patients, these findings suggest that TCM may offer a valuable alternative or adjuvant therapy to conventional Western treatments, especially for those who experience significant side effects with antihistamines, corticosteroids, or other allopathic medications. The personalized TCM approach, based on individual constitution and specific disease manifestations, is particularly relevant for allergic conditions where standardized treatments often fail. For healthcare professionals, the study highlights the importance of considering integrative models that combine the precise detection of Western medicine with the holistic regulation of Chinese medicine. TCM non-pharmacological therapies, such as acupuncture and massage, offer treatment options with a lower incidence of adverse effects, making them especially attractive for long-term management.

In addition, the ability of TCM to simultaneously modulate multiple physiological systems not only alleviates symptoms but also corrects underlying imbalances that sustain the development and perpetuation of allergic diseases.

The study presents some important limitations that should be considered in interpreting the results. Much of the research cited involves insufficient sample sizes, limiting generalization of the findings. There is a need for deeper exploration of the mechanisms of action of TCM formulas and therapies, as well as better extraction and identification of fundamental active ingredients. Evaluation of clinical efficacy also requires more robust and standardized studies.

Additionally, although the study provides a comprehensive view of TCM applications, the practical integration between Chinese and Western medicine still faces challenges related to treatment standardization, adequate professional training, and the development of integrative clinical protocols. Despite these limitations, the future of TCM in the treatment of allergic diseases appears promising, especially with the integration of modern technologies and the continued development of research that combines both medical systems, maximizing their complementary advantages for the benefit of patients.
