Highly nutritious, this relative of celery is one of the world’s most popular herbs. Parsley (Petroselinum crispum) is native to the Mediterranean region of Southern Europe. While it has been cultivated for more than 2,000 years, parsley was used medicinally before being consumed as a food. The many phytochemicals in parley provide a wide range of activities including such as protecting the brain and liver, lowering blood pressure, protecting the stomach’s gastric mucosa barrier. It exerts some analgesic, anti-bacterial, and anti-fungal actions as well. Parsley leaves can be used chewed as an effective breath freshener.
