Researchers at Newcastle General Hospital have determined that lotions containing an essential oil from lemon balm may help reduce agitation and improve quality of life for dementia patients. This finding is consistent with previous research indicating that the scent of lemon improves mental performance. The Newcastle study provides further justification for scenting areas with lemon scent where mental activities must be conducted under stressful circumstances.
