The fresh juices of Herba Houttuyniae aerial parts, Epipremnum pinnatum stems and Rhizoma Typhonium Flagelliforme were tested for their folkloric use to treat wounds and various skin ailments (Table 1 ). All these fresh juices displayed some activities (less than 30% of the activity of methicillin 5 μg) against S. aureus. However, they were inactive against the rest of the test organisms. While the yields of fresh juices were lower than those of other extraction methods, antibacterial activities against S. aureus implied reduced degradation of the bioactive principles.
