Garlic (Allium sativum) has a long history of use in traditional medicine for various skin conditions, including dermatitis. In many cultures, garlic has been applied topically or consumed to treat infections, inflammations, and skin irritations. The main rationale comes from garlic's recognized antimicrobial and anti-inflammatory properties, attributed primarily to its sulfur-containing compounds such as allicin. Folk remedies often suggest rubbing raw garlic or garlic-infused oils on affected skin to reduce symptoms of eczema, dermatitis, or fungal infections.

However, scientific evidence directly supporting garlic's efficacy in treating dermatitis is limited and mixed. Some in vitro studies have demonstrated that garlic extracts possess antibacterial and antifungal activities, which might help prevent secondary infections associated with dermatitis. A few small clinical studies and case reports suggest potential benefits, but also highlight risks, such as allergic reactions or skin irritation, especially when raw garlic is applied directly. In fact, contact dermatitis due to garlic exposure (particularly from topical use) is well-documented among chefs and in traditional medicine users.

In summary, the use of garlic bulb for dermatitis is primarily justified by traditional practices, with minimal and low-quality scientific evidence supporting its effectiveness. Caution is advised due to the risk of contact dermatitis and potential skin burns when using undiluted or raw garlic preparations.
