About
Fresh garlic juice — natural antimicrobial but also a documented cause of chemical burns and contact dermatitis when applied to skin.
Allium sativum bulb juice is the liquid extracted from fresh garlic bulbs (CAS for garlic oil: 8008-99-9). It contains sulfur-containing compounds including allicin, diallyl disulfide, and ajoene, which provide antimicrobial activity. However, topical application of fresh garlic juice is repeatedly documented in the dermatology literature as a cause of irritant and chemical burns, especially under occlusion, and as a contact sensitizer. Garlic allergy and cross-reactivity with other alliaceous plants is established. It also has strong odor and photosensitization reports. In cosmetics it is rarely used at high concentrations for these reasons; properly formulated, very-low-level inclusion can be safer.
