Rich in polyphenols-phenolic compounds with antioxidant activity which exert a number of powerful antibacterial and antifungal properties against pathogens that may cause serious human health problems. Several studies show that cistus holds  activity against Streptococcus mucans, Staphylococcus aureus and different Candida species.

Also it has strong antiviral properties. It prevents viral infection by targeting viral envelope proteins. Viral envelope proteins are proteins embedded in the capsule of a virus, which is the shell-like layer that encapsulates the viral DNA or RNA. The viral DNA and RNA are the genetic material that a virus uses to replicate once it is in a host .
