Safety, Cautions & Contraindications

Safety note[12, 13, 14]Caution

Generally safe at therapeutic doses for short-term use. Hop preparations may enhance the sedative effects of alcohol, benzodiazepines, and other CNS depressants — avoid combination. Not recommended during pregnancy or breastfeeding. May have mild oestrogenic effects due to 8-prenylnaringenin — caution in hormone-sensitive conditions. Fresh hops can cause contact dermatitis in pickers.

Safety note[12, 13, 14]Caution

Duke (2002) rates hops as +++ and provides clinical evidence (score 2) for sedative activity, consistent with Commission E approval for nervousness, unrest, and sleep disturbances. The primary sedative compound is 2-methyl-3-buten-2-ol, formed from humulone during storage. Duke notes that hop cones have estrogenic activity, explaining occupational menstrual irregularities reported among hop pickers. Dose: 0.5 g dried flower in tea before bed; often combined with valerian. Hops should not be used in depression, as its CNS-depressant effect may worsen depressive symptoms (Duke, 2002).
