Rating (out of 5): 2

Olive oil, particularly extra virgin olive oil, has been used both traditionally and in contemporary alternative medicine to support skin health, including for conditions like psoriasis. The scientific rationale for using olive oil in psoriasis is based primarily on its anti-inflammatory, antioxidant, and moisturizing properties. Olive oil contains high levels of monounsaturated fatty acids (especially oleic acid) and phenolic compounds, which have demonstrated ability to reduce oxidative stress and inflammation in laboratory and animal studies. Some small clinical studies and case reports suggest that topical application of olive oil can help soothe psoriatic plaques, reduce scaling, and improve skin hydration, especially when used as an adjunct to other treatments or as a carrier for medicated ointments. However, the evidence base is limited. While olive oil is generally well tolerated and may provide symptomatic relief, there is a lack of robust, large-scale randomized controlled trials directly assessing its efficacy for psoriasis. Some dermatologists caution that, in rare cases, the use of pure olive oil might irritate sensitive skin or worsen symptoms in some individuals. Traditional use and preliminary studies justify its inclusion as a supportive measure, but it should not replace established medical therapies. Overall, olive oil can be considered a mild, accessible adjunct for some patients, but its benefits are likely modest and require further scientific validation.
