    Viridian Organic Evening Primrose Oil

    Our verdict

    Widely bought for cyclical breast tenderness, where the evidence is weak but the risk is low. Not something to persist with beyond a three-month trial if nothing changes, and not suitable if you have epilepsy.

    Pros

    • +Organic, single ingredient

    Cons

    • -Weak evidence
    • -Avoid with epilepsy or anticoagulants

    Evidence

    Evidence for breast tenderness is weak and for hot flushes weaker still. Widely sold, rarely impressive.

    Best for
