Benzodiazepines
Class of anxiolytic and sedative medications acting on the brain's GABA-A receptors. Effective in the short term for anxiety and insomnia, but with a risk of dependence and tolerance in the long term. Several medicinal plants (valerian, passionflower, hops) act on the same system and can potentiate their effect: never combine them without medical advice.
Never use a dietary supplement without the advice of a healthcare professional. Overdoses as well as deficiencies are not without risk.
