Hops
Plant (Humulus lupulus) known as a beer ingredient, but also used in herbal medicine for its sedative properties. Contains 2-methyl-3-buten-2-ol, a metabolite active on the central nervous system. Often combined with valerian in herbal sleep formulas, with greater effectiveness in combination.
Never use a dietary supplement without the advice of a healthcare professional. Overdoses as well as deficiencies are not without risk.
