Does Garlic Help Allergies & Sinus Problems?

By Lacretia Hardy ; Updated August 14, 2017

Sinus problems are often the result of a cold virus, upper respiratory tract infection or allergy. Conventional medicine offers treatment for the symptoms of allergies and sinus but there is no medicine available at present to prevent the condition from occurring. There are, however, several medicinal plants which seem to prevent the problems of allergies and sinus, and of these garlic appears to be the most promising.

Allergies And Sinus

An allergy is the exaggerated reaction of your immune system to a foreign substance. Pollens, dust mites, mold and food are examples of allergens, or substances that may cause allergic symptoms. About 35 million Americans -- 6 million of whom are children -- suffer from allergic rhinitis which is an inflammation of the mucous membranes in your nose. According to the Centers for Disease Control and Prevention, sinusitis is also a very common problem affecting 29.3 million Americans in 2009. The condition occurs when the mucous lining in the cavities of the head, which are attached to the nasal passages become inflamed.


Garlic is an herb rich in antioxidants. Antioxidants are substances that play an important role in destroying the free radicals produced by environmental toxins such as ultraviolet light, radiation, cigarette smoke and air pollution. Due to this antioxidant property, garlic is beneficial in providing relief from sinus congestion resulting from exposure to environmental allergies. The University of Maryland Medical Center recommends garlic for relief from symptoms of cold and sinus.

Preparations of Garlic

A study published in the "Journal of Nutrition" investigated the activities of four garlic preparations: raw garlic juice, heated garlic juice, dehydrated garlic powder and aged garlic extract to determine their medical effectiveness. The results suggest that different types of garlic preparations have different medicinal properties, and among the four garlic preparations studied, aged garlic extract could be the most useful garlic preparation.

Garlic, Allergies And Sinus

Aged garlic extract acts as an immune modifier and maintains the good working order of your body’s immune functions, according to a research published in the "Journal of Nutrition" in 2001. This function of garlic can be beneficial in containing allergies. Similarly, a study published in "Advances in Therapy" in 2001 found garlic to be effective in preventing attacks of the common cold that can lead to sinus problems.
