Raw garlic has been used for centuries across many cultures as a go-to home remedy, and modern research has begun to explore the science behind this tradition. Studies indicate that allicin, the sulfur compound released when garlic is crushed or chopped, may contribute to antimicrobial activity against certain bacteria and fungi. Research suggests that regular consumption of raw garlic may support immune function, with some studies pointing to potential benefits for blood pressure regulation and reduced severity of common colds and flu symptoms. Folk traditions have also used warmed garlic preparations near the ear for minor discomfort, though scientific evidence in this area remains limited. As one of the most accessible pantry remedies, raw garlic continues to attract both cultural appreciation and scientific curiosity.
