Mallow (Malva sylvestris and related species) has a long history of use in traditional herbal medicine, primarily for its soothing and anti-inflammatory properties. In some folk medicine systems, mallow has been included in herbal combinations or teas aimed at promoting relaxation and alleviating minor sleep disturbances. However, its use specifically for insomnia is not widespread or strongly emphasized in traditional texts compared to herbs like valerian, chamomile, or passionflower.

There is little to no scientific research directly evaluating mallow for the treatment of insomnia. Most studies on mallow focus on its antioxidant, anti-inflammatory, and mucilaginous activities, which are unrelated to sleep regulation. The rationale for its occasional traditional use in sleep-supporting teas is likely due to its mild calming effects and its role in soothing digestive or respiratory discomfort that might indirectly impact sleep quality.

Overall, the evidence for mallow’s effectiveness in treating insomnia is minimal and primarily based on tradition rather than scientific validation. Its use for this purpose is rated very low due to the lack of direct supportive data and limited prominence in both historical and modern herbal practice for insomnia.
