Herbs have been part of human culture since the beginning of time. Although they add the characteristic Italian flavor of spaghetti sauce, as well as that nutty-exotic flavor of Indian curry dishes, herbs have long been used for medicinal purposes as well. Humans have been using herbs for medicine for at least 60,000 years. Salicylic acid, for example, is an age-old pain reliever that comes from willow bark. From soothing stomach aches with peppermint to essential oil therapy and bone-regrowth teas, herbs have long been valuable resources for people.
