Himalaya Party Smart - When alcohol is consumed, it is mainly converted into acetaldehyde (an intermediate metabolite of alcohol metabolism) by the liver. Acetaldehyde at higher concentrations leads to unpleasant after-effects such as fatigue, headache, nausea, vomiting, body ache, burning sensation in the stomach and drowsiness. PartySmart prevents these symptoms by rapidly eliminating acetaldehyde from blood. The drug eliminates acetaldehyde by increasing ADH (alcohol dehydrogenase) and ALDH (aldehyde dehydrogenase) activity, without any side effects.
