It seems that garlic and its volatile oil can be used in basically any natural remedy, as it has a comprehensive effect on many different organ systems in the body. The high concentration of allicin, garlic’s active volatile ingredient, as well as sulfuric and antioxidant compounds, make garlic oil an effective way to eliminate a fungal infection in the lungs. Garlic oil can do it all… neutralize the infection, stimulate the immune system, speed up the healing process and eliminate the inflammation from the respiratory tracts. Garlic oil can be put on salads, used for cooking, or mixed with water for a concentrated tonic!
