Natural Hangover Remedies: What the Evidence Does and Doesn’t Show

Everyone has a hangover theory — greasy food, coffee, sweating it out, coconut water, pickle juice. This is an honest tour of the most common natural hangover remedies and what the research does and doesn’t support. The short version up front: there is no proven cure for a hangover. Some remedies have real biological rationale and a little human data; most rest on tradition or address one symptom at the margins. We’ll say which is which.

First, the honest caveat

A hangover isn’t one thing. It’s a cluster of overlapping effects — disrupted sleep, fluid and electrolyte shifts, a rebound in nervous-system activity after alcohol clears, inflammation, and the lingering by-products of alcohol metabolism. No single remedy touches all of those, and the research on hangover-specific interventions is thin: most studies are small, short, or done in populations that aren’t “an otherwise healthy adult who had a few drinks at dinner.”

So treat any “what works” list — including this one — as a guide to plausibility, not a ranking of cures. The most reliable lever remains how much you drink and how well you sleep. With that said, here’s how the common natural remedies stack up.

Remedies with some human data and a clear rationale

DHM (dihydromyricetin)

DHM is a flavonoid from the Oriental raisin tree (Hovenia dulcis), used in traditional East Asian preparations associated with alcohol and liver support — historical context, not proof of effect. It’s become the most common active in the recovery-supplement category: one 2025 analysis in a Sage journal found DHM present in roughly 47.6% of US hangover-supplement products.

What the research actually shows is preliminary. The most-cited study is a 2012 UCLA paper in the Journal of Neuroscience that examined DHM’s effect on GABA-A receptor signalling — in rodents, not people. Researchers have proposed that DHM may influence the activity of the body’s alcohol-metabolizing enzymes and GABA-A signalling, but the human evidence is limited and hasn’t been replicated at the scale you’d want before calling anything settled.

Honest bottom line: DHM has the most research attention of any remedy on this list and a plausible mechanism, but the human data is still early. It’s a reasonable thing to be interested in; it is not a proven cure.

Typical research and product doses range from about 300 mg to 1,200 mg. Many budget products sit near 300 mg; some are higher. (For a closer look, see our 300 mg vs 1,000 mg DHM dosage breakdown.)

Prickly pear (Opuntia ficus-indica)

Prickly pear is one of the few remedies with a hangover-specific human trial. A 2004 study by Wiese and colleagues, published in Archives of Internal Medicine, gave participants prickly pear extract or placebo before drinking. The authors reported that a few symptom scores — notably nausea and dry mouth — were lower in the extract group, alongside a reduction in a marker of inflammation, though overall hangover severity wasn’t eliminated.

It’s a small, single trial, so read it as suggestive rather than definitive. The proposed rationale is anti-inflammatory, which would address the flu-like component some people feel and not much else.

Electrolytes and fluids

This is the least controversial item. Alcohol suppresses a hormone that helps your body retain water, increasing urine output and the loss of sodium, potassium and magnesium along with it. Replacing fluids and electrolytes is sound physiology, and it’s why oral rehydration solutions and electrolyte drinks feel like they help.

One nuance worth knowing: water alone doesn’t replace lost electrolytes, and drinking large volumes of plain water while depleted can dilute blood sodium further. A balanced approach — fluids plus sodium, potassium and magnesium — makes more sense than chugging water alone. This addresses the dehydration side of a hangover; it does nothing for the rebound or metabolic side.

Remedies with a plausible mechanism but limited hangover data

Ginger

Ginger has solid human evidence as an anti-nausea agent — in pregnancy, post-surgery and chemotherapy-related nausea. Whether that transfers to hangover nausea specifically hasn’t been tested in a dedicated trial, so the extrapolation is reasonable but unproven. If nausea is your main complaint, ginger tea is a low-risk thing to try; just don’t expect it to touch the rest of the hangover.

B vitamins

Alcohol increases the excretion of B vitamins and can impair their absorption, so the depletion is real. Whether topping them back up in a non-deficient adult changes how a hangover feels is much less documented — there aren’t hangover-specific trials showing symptom relief. They’re inexpensive and safe at normal doses, which is the honest case for them: low downside, uncertain upside.

Food before drinking

Eating before you drink — especially protein and fat — slows how fast alcohol is absorbed, which lowers peak blood alcohol for a given amount. That’s well established. But it’s a prevention strategy, not a morning-after remedy: by the time you’re hungover, the alcohol is long absorbed. (More on timing in our pre-drinking protocol.)

Popular remedies with weak or no support

Coffee and caffeine

Caffeine blocks adenosine and creates temporary alertness, which can mask fatigue. It doesn’t address the nervous-system rebound, inflammation or dehydration — and as a mild diuretic it may nudge dehydration the wrong way. Useful for feeling functional; not a remedy for the underlying state.

Greasy food the morning after

A greasy breakfast can steady blood sugar and offer comfort, and slowing the gut may ease nausea a little. But the alcohol is fully absorbed by morning, so food at that point isn’t acting on the core drivers of a hangover. It’s tolerating the morning, not fixing it.

Coconut water

Better than plain water because it supplies some potassium, but it’s relatively low in sodium — the electrolyte alcohol depletes most — and lacks magnesium. Fine as a palatable drink; not a complete electrolyte replacement.

Activated charcoal

The pitch is that charcoal “binds toxins.” Alcohol is absorbed from the small intestine quickly, so by the time you’d take charcoal the alcohol is already in your bloodstream, where charcoal in the gut can’t reach it. There’s no plausible mechanism for it to help a next-morning hangover.

Remedies to skip

”Hair of the dog”

Drinking more does temporarily blunt the worst of the rebound by re-introducing alcohol — but it postpones the problem rather than resolving it, adds to your total alcohol load, and is exactly the pattern that makes morning drinking a risk. Not a remedy.

”Sweating it out” with intense exercise

Sweat doesn’t clear meaningful amounts of alcohol or its by-products — that’s the liver’s job — so the “sweat out the toxins” idea doesn’t hold. Hard exercise while dehydrated and depleted adds physiological stress. A gentle walk is fine and may help you feel better; an intense workout isn’t the move.

IV “hydration” bars

An IV efficiently delivers fluids and electrolytes — which you can get from oral rehydration for a few dollars — at a price often running into the hundreds. It addresses only the dehydration component, doesn’t touch the rest, and is hard to justify on value.

So what actually helps?

Stack the things with the soundest rationale and lowest risk: moderate your drinking, prioritize sleep, replace fluids and electrolytes sensibly, and eat before you drink. Symptom-specific add-ons like ginger for nausea are reasonable. Beyond that, be skeptical of anything promising to “cure” a hangover — including supplements. The category is full of confident claims that the evidence doesn’t back.

Where DHM fits in: it’s the most-studied single compound in the recovery category and the reason a lot of these products exist. That’s a reason to find it interesting, not a guarantee. If you want the full picture of how alcohol produces a hangover in the first place, start with what actually causes a hangover and the GABA rebound behind next-day anxiety.

Frequently Asked Questions

What is the best natural hangover remedy? There isn’t a single best one, because no remedy is a proven cure. The interventions with the soundest rationale are the boring ones: drinking less, sleeping, and replacing fluids and electrolytes. Among supplements, DHM has the most research attention, but the human evidence is still preliminary.

Do hangover supplements actually work? Some contain ingredients with plausible mechanisms (DHM, prickly pear) and a little human data, but hangover-specific evidence is generally thin and the studies are small. They may help some people with some symptoms; none has been shown to reliably eliminate a hangover. Treat strong “cure” claims with skepticism.

Does DHM cure hangovers? No. DHM is a flavonoid that’s drawn the most research interest in this category, and studies have examined how it may influence GABA-A signalling and alcohol-metabolizing enzymes — mostly in animals, with limited human data. It is not a proven hangover cure, and no supplement should be sold as one.

Is water enough for a hangover? Water helps with dehydration but doesn’t replace the sodium, potassium and magnesium alcohol depletes — and large amounts of plain water while depleted can dilute blood sodium. Fluids plus electrolytes is the more sensible approach.

What’s the fastest way to feel better after drinking? There’s no quick fix. Rest, fluids with electrolytes, and time do the most. Targeted help for a specific symptom — for example ginger for nausea — can take the edge off, but the underlying recovery is mostly your body and the clock.
