Garlic contains compounds like allicin that have been shown to have strong antibacterial properties. These properties can help fight bacterial infections, including those that cause pneumonia. Although garlic oil alone may not be a substitute for antibiotics, it can help in the body's defense against bacterial infections.
Garlic oil may help to break down mucus and phlegm in the respiratory system. This can help alleviate symptoms like coughing and congestion, making it easier to clear the airways and breathe.
