Lemon balm (Melissa officinalis), a member of the mint family, is considered a calming herb. Even before the Middle Ages, lemon balm was steeped in wine to lift the spirits, help heal wounds, and treat venomous insect bites and stings. Today, lemon balm is often combined with other calming, soothing herbs, such as valerian, chamomile, and hops, to promote relaxation. Health studies have shown that lemon balm can increase individuals' sense of well-being, happiness, and alertness. Lemon balm has antimicrobial activity (antiparasitic, antibacterial, antiviral, etc), antispasmodic, antioxidant and insomnia properties. Lemon balm may help you fall asleep.
