Overview

Pelargonium sidoides, also known as Umckaloabo or South African geranium, is a medicinal plant whose root extract is used to treat respiratory infections. It has a unique triple mechanism of action: it is antiviral, antibacterial, and an expectorant. It is thought to prevent bacteria and viruses from attaching to cells in the respiratory tract, and it stimulates the immune system to fight off pathogens while also helping to thin and expel mucus.
