Summary
Hop (Humulus lupulus L.) is mainly used in the brewing industry and less in medicine and cosmetics. This well-known raw herbal material is a component of many pharmacological agents soothing and strengthening the body.
Ultraviolet radiation has a strong photobiological and photochemical impact and therefore particularly affects the human live and health. Solar radiation brings sometimes advantages such as alleviating the symptoms of asthma or arthritis, and tanned skin looks healthy and radially. However, the long-term effects of UV radiation on the skin is very unfavourable. Therefore, effective protection against UV radiation becomes necessary to enjoy the young skin and a strong immune system for a long time. In recent years various herbal infusions, extracts and essential oils are tested, as substances that have ultraviolet protection properties. The aim of this work was to examine ultraviolet protection properties of essential oil, infusions and extracts of hop (Humulus lupulus L.) using several methods in vitro that are commonly used to determine the protection properties of the cosmetic preparations against UV radiation. The results obtained indicate that both infusions as well as extracts and essential oil of hop have a high or medium UV protection properties.
