Herbal Medicine: The Healing Power of Herbs
Diego Andres Villamarin
Plants have been used as medicines for thousands of years. Many medications prescribed today were first discovered in plants; the heart medication “Digoxin” comes from the foxglove plant [1,2]. This article discusses herbal medicine; however, it is extremely important to speak with your doctor before using herbs (including supplements) since they might not be safe for everyone and might interfere with other prescribed medications.
First, let’s distinguish between dried herbs and fresh herbs. Dried herbs have about four times the flavor of fresh herbs. However, fresh herbs have higher antioxidant levels . Antioxidants protect our cells and so are good to have in our diet . Simmering or stewing foods with fresh herbs increase its antioxidant levels . But frying and grilling them will decrease its antioxidant levels.
Here are common uses, benefits, side effects, and preparations of some herbs [5,6,7,8]:
