Hops' effects (Humulus lupulus) have been known in European herbalism for centuries. The active ingredients are concentrated in the resin of the female flowers' hop cones. These include bitter compounds, essential oil and a broad spectrum of flavonoids and proanthocyanidins.
The coriander plant (Coriandrum sativum) is also called the "herb of longevity" in Chinese tradition. The fruits (seeds) and leaves also differ in their areas of action and application due to their individual ingredient profiles of antioxidants, essential oils and tannins.
