Allium species, most notably garlic (Allium sativum) and onion (Allium cepa), have a long history of traditional use in treating respiratory conditions, including bronchitis. Historical records from various cultures—such as ancient Egypt, Greece, China, and India—describe the use of garlic and onion preparations for coughs, colds, and bronchial ailments. The rationale behind their use is primarily attributed to their pungent sulfur-containing compounds (like allicin in garlic), which were believed to have antimicrobial, expectorant, and anti-inflammatory properties.

Some laboratory studies have demonstrated antibacterial and antiviral activity of Allium extracts against pathogens that can cause respiratory infections. However, direct clinical evidence specifically supporting the use of unspecific Allium for bronchitis in humans is limited and typically of low quality. Most supporting studies are either in vitro, animal-based, or involve small, poorly controlled human trials. Systematic reviews and reputable herbal medicine references consistently cite traditional usage for bronchitis, but emphasize the lack of robust modern clinical evidence.

In summary, Allium's use in bronchitis is well-rooted in traditional medicine, with some preliminary pharmacological rationale, but lacks strong scientific validation from rigorous clinical trials.
