Prevalence of asthma and allergy has increased over the past 2–3 decades in Westernized countries. Despite increased understanding of the pathogenesis of asthma and allergic diseases, control of severe asthma is still difficult. Asthma is also associated with high prevalence of anxiety in particular adolescents. There is no effective treatment for food allergy. Food allergy is often associated with severe and recalcitrant eczema. Novel approaches for treatment of asthma and food allergy and comorbid conditions are urgently needed. Traditional Chinese medicine (TCM), used in Asia for centuries, is beginning to play a role in Western health care. There is increasing scientific evidence supporting the use of TCM for asthma treatment. This review article discusses promising TCM interventions for asthma, food allergy and comorbid conditions and explores their possible mechanisms of action. Since 2005, several controlled clinical studies of “anti-asthma” herbal remedies have been published. Among the herbal medicines, anti-asthma herbal medicine intervention (ASHMI) is the only anti-asthma TCM product that is a US FDA investigational new drug (IND) that has entered clinical trials. Research into ASHMI’s effects and mechanisms of actions in animal models is actively being pursued. Research on TCM herbal medicines for treating food allergy is rare. The herbal intervention, Food Allergy Herbal Formula-2 (FAHF-2) is the only US FDA botanical IND under investigation as a multiple food allergy therapy. Published articles and abstracts, as well as new data generated in preclinical and clinical studies of ASHMI and FAHF-2 are the bases for this review. The effect of TCM therapy on food allergy associated recalcitrant eczema, based on case review, is also included. Laboratory and clinical studies demonstrate a beneficial effect of ASHMI treatment on asthma. The possible mechanisms underlying the efficacy are multiple. Preclinical studies demonstrated the efficacy and safety of FAHF-2 for treating food allergy in a murine model. A clinical study demonstrated that FAHF-2 is safe, well tolerated, and exhibited beneficial immunomodulatory effects. A clinical report showed that TCM treatment reduced eczema scores and improved quality of life. Herbal interventions, ASHMI and FAHF-2 may be further developed as botanical drugs for treating asthma and food allergy. TCM may also be of benefit for comorbid conditions such as anxiety and recalcitrant eczema. More controlled studies are warranted. In conclusion, novel approaches for treatment of asthma and food allergy and comorbid conditions such as anxiety and eczema are urgently needed. This article discusses promising interventions for such conditions from traditional Chinese medicine (TCM) and explores their possible mechanisms of action.
