Parsley (Petroselinum crispum) is best known as a plate garnish whose use is not only decorative, but also works as an after-dinner breath mint to reduce mouth odor. This is due to Chlorophyll, abundant in fresh parsley, which does indeed absorb odors. Parsley is also a good source of iron and trace elements needed for good health. Parsley is one of the oldest and longest-used herbs known to man. It was described in a Greek herbal written in the third century B.C. and is probably a native of the eastern Mediterranean area, though its exact origin is not known. In ancient Greece, Parsley was placed in wreaths given to winning athletes because the Greeks believed that the god Hercules had chosen Parsley for his garlands. Today, in addition to a garnish, Parsley is used extensively in food preparation to enhance the flavor of meats, fish, fowl, eggs and vegetables.Alvita.
