Characteristics of Prunella
Prunella species share several key characteristics that make them easily recognizable. They are typically low-growing, herbaceous plants with square stems and opposite leaves.

These plants are also known for their hardiness and adaptability, able to thrive in a variety of conditions.
Traditional Uses and Modern Research
Prunella has a long history of use in traditional medicine, particularly in Europe and Asia. The common self-heal (Prunella vulgaris) is the most widely used species and has been traditionally employed to treat a variety of ailments, including wounds, sores, sore throats, and internal bleeding. Its purported medicinal properties are attributed to its high content of tannins, flavonoids, and other bioactive compounds.
Modern research has begun to explore the potential health benefits of Prunella. Studies have suggested that extracts from Prunella vulgaris may possess anti-inflammatory, antioxidant, antiviral, and antibacterial properties. While more research is needed to fully understand the therapeutic potential of Prunella, these preliminary findings are promising.
