Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Linseed oil, also known as flaxseed oil, has been traditionally used in various cultures for its purported skin health benefits, including for conditions like psoriasis. The traditional use is largely based on the oil’s high content of alpha-linolenic acid (ALA), an omega-3 fatty acid believed to have anti-inflammatory properties. Folk medicine has recommended the topical or dietary use of linseed oil to soothe dry, irritated, or inflamed skin, which includes psoriatic lesions. However, while there are anecdotal reports and some small studies suggesting that omega-3 fatty acids may help reduce inflammation in chronic skin diseases, direct scientific evidence supporting the effectiveness of linseed oil specifically for psoriasis is limited and inconsistent. Most clinical studies on omega-3 supplementation for psoriasis have focused on fish oil rather than plant-based sources like linseed oil, often with modest or inconclusive results. Therefore, while linseed oil’s use for psoriasis is primarily justified by tradition, the current scientific evidence base is weak, meriting a low evidence rating.
