The short answer
Gush is whole Korean pear juice, packaged into a single-serve pouch and designed to be sipped before you drink alcohol — not after. It's built around a specific pear, Pyrus pyrifolia cv. Shingo, that's been used in Korea for centuries around drinking occasions, and around a real body of peer-reviewed research showing it reduces hangover severity and supports how your body processes alcohol.
That's it. No proprietary blend, no synthetic isolate — real pear juice, backed by centuries of use and real research, meant to be part of your night before it starts, not a cure the morning after.
The pear
Pyrus pyrifolia, commonly called Korean pear, Asian pear, or nashi pear, is crisper and juicier than a typical Western pear — closer to an apple in texture. Long before it was a research subject, it was a household staple in Korea, eaten or juiced around meals that included alcohol. That's centuries of real-world social proof — something almost nothing else in this category can claim.
The research
Two peer-reviewed studies anchor what Gush is built on:
- A 2013 human trial in Food and Chemical Toxicology found Korean pear juice reduced hangover severity by 16–21% and lowered both blood alcohol and blood acetaldehyde levels. Read the full breakdown in the study behind the pear.
- A 2012 mechanism study in Phytotherapy Research found Korean pear stimulates the two enzymes — ADH and ALDH — responsible for clearing alcohol and its toxic byproducts. More in ADH and ALDH, explained.
Why juice, not a capsule
Most hangover products isolate a single compound into a pill. Gush uses the whole fruit instead — the same enzyme-support work as a beverage, plus the hydration, electrolytes, and antioxidants only a real drink can offer, and none of the queasiness people often report from isolated DHM capsules. More on why that's deliberate in whole fruit vs. the pill.
How to actually use it
One pouch, about 20–30 minutes before your first drink. Not the next morning — the research this is built on tested pear juice as a before-drinking ritual, not a hangover-day rescue.
Centuries of use, a human study, and a drink you'll actually enjoy — that's the whole idea. Try Gush, or keep exploring the science in The Gush Lab.
