Rating (out of 5): 2

Garlic bulb (Allium sativum) has a long history of use in traditional medicine systems, particularly for alleviating symptoms of respiratory congestion. In folk medicine, garlic is often recommended for colds, coughs, and congestion due to its perceived ability to "clear the airways," reduce phlegm, and fight infections. The traditional rationale centers on garlic’s strong aroma and the pungent nature of its bioactive compounds (such as allicin), which are believed to help open up nasal passages when consumed or inhaled. Preparations include raw garlic, garlic-infused oils, or teas.

From a scientific perspective, some studies have demonstrated that garlic possesses antimicrobial, antiviral, and anti-inflammatory properties, which could theoretically contribute to reducing the duration or severity of upper respiratory tract infections. However, direct evidence supporting garlic’s effectiveness specifically for congestion relief is limited. Most clinical trials focus on its potential to reduce the frequency or duration of common colds rather than targeting congestion symptoms specifically. Inhalation of garlic vapors is anecdotally reported to help with nasal stuffiness, but this practice lacks robust scientific validation.

In summary, the use of garlic for treating congestion is primarily rooted in traditional practices, with limited scientific evidence directly supporting its efficacy for this specific symptom. More rigorous clinical studies would be needed to substantiate its therapeutic role in managing congestion.
