To date, researchers have identified dozens of flavonoids in chaparral which act as cellular enhancers, as well as a powerful antioxidant called NDGA. Recently, researchers at Arizona State University discovered that chaparral demonstrates strong antiviral activity particularly on the Herpes family of viruses.
Chaparral may have an advantage over drug therapy for treatment of viruses by inhibiting the viral genes without damaging your living cells. Drugs work by interfering with the reproduction of viral DNA, but also inhibit synthesis of your own DNA, which suppresses your immune system. Chaparral seems to attack the virus and enforce the immune system with antioxidant flavonoids.
