Lemon Balm Extract Powder (Melissa) is commonly used in Europe as a tea, liquid extract, and topical preparation. Ancient Greeks and Romans used melissa in surgical dressings for wounds and in preparations to treat venomous or infectious bites and stings such as with dogs and scorpions. Today, melissa's primary use involves the treatment of cold sores and teething. It is also commonly used as an antibacterial and antifungal agent.
