Some of these plants carry free anti-inflammatory activities that are helpful against various diseases.

The study reviews medicinal plants that grow whose antioxidant, antiviral, anti-inflammatory, and immune-modulatory characteristics are already known, also in the framework of the prevention and treatment of pneumonia of various etiologies. The need for a comprehensive approach to maintaining immune defenses, including functional foods and positive emotions, is emphasized.
