Garlic's medicinal value is largely in its being a highly volatile essential oil, so precautionary care should be taken in its preparation. Anciently it was used in both healing and nutrition, as it was known to possess a great resource for physical strength and energy. It is a valuable nervine tonic, and is especially useful in lowering hypertension.

According to one investigator, the oil is composed of sulfides and disulfides which halt the accelerated harmful effects while not harming the healthful organisms. The garlic oil is reportedly so popular in Russian medicine that it is referred to as "Russian penicillin," and the hospitals and clinics use the volatile garlic extracts almost exclusively in the form of vapors and inhalants. The use of garlic as an antiseptic and vulnerary during World War I was sensational; and wherever there is pus, it is a safe and certain remedy.
