The present study was aimed to investigate the activity of plants traditionally used in Northern Peru against acne. Various bacteria, especially Propioniobacterium acnes have been identified as triggering this condition. The normal control of acne in western medicine often causes side effects like skin irritations. Peru has a rich variety of plants that are proven to have antibacterial and anti-inflammatory properties. The study found that Canchalagua (Schkuhria pinnata (Lam.) Kuntze), Hercampuri
Acne vulgaris is a condition that affects skin areas containing large oil glands of people of all races and ages (Leydon, 1997). It is most common in adolescents and young adults. An estimated 80 percent of all people between the ages of 11 and 30 have acne outbreaks at some point (Holding, 2004). Propioniobacterium acnes often involved in the condition, proliferates rapidly especially during puberty (Hamnerius, 1996). P. acnes leads mostly to inflammatory acne, while other bacteria like Staphylococcus epidermis usually cause superficial infections (Burkhart et al, 1999). For most people, acne tends to go away by the time they reach their thirties; however, some people in their forties and fifties continue to have this skin problem. (Gentianella alborosea (Gilg.) Fabris), and Corpus Way (Gentianella bicolor (Wedd.) J. Pringle) had promising antibacterial properties and efficiency against acne.
