Party is an herbal formulation that helps prevent hangovers. It is clinically proven, safe, and effective. When you consume alcohol, it is broken down into acetaldehyde. Acetaldehyde is primarily responsible for hangovers. The buildup of acetaldehyde in the liver leads to a hangover, or a not-so-good morning. Himalaya Partypro helps prevent hangovers by preventing acetaldehyde buildup in the liver, leading to a better morning.
