Plant-Based Treatments for Asthma and Chronic Obstructive Pulmonary Disease (COPD)

Abstract

Asthma and chronic obstructive pulmonary disease (COPD) are long-term respiratory disorders characterized by airway inflammation, blockage, and oxidative stress. These conditions compromise lung function and negatively impact overall quality of life. While conventional medications are effective, they can often lead to undesirable side effects, sparking interest in alternative therapeutic approaches. Plant-based therapies, leveraging bioactive compounds found in medicinal herbs, present promising complementary or alternative options. Natural compounds like flavonoids, terpenoids, alkaloids, and phenolic acids possess anti-inflammatory, antioxidant, and bronchodilatory effects, which can help alleviate symptoms of asthma and COPD. This chapter explores the therapeutic potential of plant-based treatments, examining species like Boswellia serrata, Glycyrrhiza glabra, and Curcuma longa, which have demonstrated positive outcomes in both preclinical and clinical research. Topics include the mechanisms by which these phytochemicals exert therapeutic effects, their health benefits, and the challenges in incorporating plant-based remedies into conventional care. Additionally, the chapter discusses current research gaps and future directions to improve the safety, efficacy, and availability of plant-derived treatments for respiratory diseases, aiming to reduce dependence on synthetic medications. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.
