The Quest for an ‘Asian Flush’ Treatment

When Asians wish to occasion, they know there may very well be a snag. They may very well be struck by — what’s affectionately known as — the Asian flush.

Roughly 50 % of individuals with Chinese language, Korean and Japanese ancestry expertise alcohol flush response whereas consuming due to an inherited genetic mutation. Because of this, their our bodies are poor in a key enzyme wanted to interrupt down alcohol. A sip or two of the arduous stuff may be all that it takes to set off a heat, purple rash throughout the face, chest, and arms. As a result of this alcohol-included glow may be inconvenient, uncomfortable, and possibly even a bit embarrassing, Singaporean entrepreneurs Solomon Poon and Ryan Foo noticed a chance to create a treatment.

They’ve launched DrinkAid, a complement they declare will preserve the dreaded flush away if taken a few hours earlier than the boozing begins. Whereas Poon and Foo will not be the primary to try to sort out this aspect impact, Poon says that victims usually flip to merchandise that aren’t designed to deal with it. “One of many well-known options is a medicine known as Pepcid, a histamine blocker,” says Poon. The histamine blocker could gradual pores and skin redness, however victims typically nonetheless expertise the opposite signs of the situation, equivalent to complications, nausea, or speedy heartbeat.

When DrinkAid launched in August 2020, Poon and Foo say orders had been positioned from world wide. However not everybody’s tickled pink with the prospect of anti-flush capsules.

Michael Kenny, an inner medication doctor in Los Angeles, isn’t satisfied that dietary supplements for alcohol flush response really work. “These dietary supplements include components that ought to theoretically shield the liver,” says Kenny. “They haven’t been proven to constantly stop Asian flush in medical research, and these merchandise will not be FDA accepted.”

However regardless of this, Foo and Poon say that client demand for DrinkAid is robust. And, they stand behind their complement, which they are saying targets the foundation causes of the redness.

Breaking it Down

The flush is the results of the physique’s lack of ability to interrupt down acetaldehyde, which is a poisonous byproduct of metabolizing alcohol. Usually, this byproduct is transformed into innocent compounds by a liver enzyme known as aldehyde dehydrogenase, however in keeping with Esteban Kosak, a doctor primarily based in Venezuela, individuals who flush whereas consuming alcohol have an inactive model of this enzyme.

“A big majority of individuals, a lot of whom are of Asian descent, don’t produce aldehyde dehydrogenase due to a gene mutation that has developed over time,” he says. “The result’s that these with the mutation accumulate six instances extra acetaldehyde, which is extremely poisonous.” The severity of the situation is dependent upon whether or not one or each dad and mom handed on the gene mutation that causes the inactive enzyme.

As a result of acetaldehyde has been studied extensively by researchers, Poon and Foo started their seek for flush cures by scouring analysis from Korea, Russia and China. Typically, the analysis on this space centered on potential hangover cures and lowering liver injury. Poon and Foo particularly looked for components that may assist the physique eliminate acetaldehyde extra shortly — which, they consider, can cease the flush earlier than it even begins.

Ultimately, Poo and Foon found the components that might type the premise of their DrinkAid complement. “We used succinic acid to enhance liver operate and Japanese raisin tree [Hovenia dulcis] to interrupt down the acetaldehyde,” says Poon. 

The leaves, bark and fruit of the Japanese raisin tree have an extended historical past of use as a hangover treatment in Japanese medication. How raisin tree precisely works within the physique, and its impact on acetaldehyde processing, continues to be poorly understood.

Nevertheless, a small research discovered that males who carried one copy of the gene mutation related to alcohol intolerance skilled fewer hangover signs in the event that they took raisin tree fruit extract along with alcohol as in comparison with a management group. The work, which was printed in Journal of Ethnopharmacology, famous that the extract might need tamped down the inflammatory response related to alcohol consumption.

This 12 months, a research printed in Alcoholism: Medical & Experimental Analysis would possibly provide clues into the position of a compound within the raisin tree known as dihydromyricetin. Amongst mice with liver injury, it promoted the manufacturing of enzymes that may break down alcohol, and made the enzymes extra environment friendly at doing their job. Among the many mice, the researchers additionally noticed that the compound decreased some results of heavy alcohol consumption on the liver, equivalent to cell injury and fats accumulation. Extra perception is required into whether or not this might assist individuals who don’t produce ample ranges of aldehyde dehydrogenase, the important thing enzyme wanted for alcohol metabolization.

Succinic acid, one other ingredient in DrinkAid, is discovered naturally in all kinds of meals. It’s thought to play a job within the manufacturing of ATP, or adenosine triphosphate, which is an energy-storing molecule that’s important to cell survival. Heavy alcohol consumption would possibly lower ATP ranges within the liver, and this may very well be an element that contributes to the event of liver illness and cirrhosis. Nevertheless, whether or not or not taking a complement with succinic acid can chase away alcohol-related liver injury is unclear, primarily based on present analysis.  

Poon and Foo say they examined DrinkAid on a small group of 30 college-aged college students, and 98 % reported no hangover and decreased alcohol flushing. Nevertheless, claims round DrinkAid haven’t been independently verified. And just like the FDA within the U.S., Singapore’s Well being Sciences Authority doesn’t regulate dietary supplements as medicines. Because of this dietary supplements aren’t held to the identical rigorous security and efficacy necessities that many medication are.

Extra Than a Crimson Face

Kenny, the doctor in Los Angeles, is a sufferer of alcohol flush himself. He raises consciousness in regards to the situation on his YouTube channel, and says that the pores and skin response is a purple flag for different potential illnesses. Researchers have discovered that victims are at a better threat of growing esophageal most cancers, and a hyperlink to Alzheimer’s is being explored.

Kenny additionally says there must be a greater resolution for individuals who expertise alcohol flushing, and are prone to flip to Pepcid after they drink. Pepcid would possibly preserve some signs away — however in flip, it could trigger somebody to drink extra, and it doesn’t do something to forestall the poisonous build-up of acetaldehyde.

Kenny has tried dietary supplements to ease alcohol flush. However he says that, anecdotally, he’s “seen inconsistent leads to stopping the flush, however some are just a little extra constant in stopping large hangovers the following day.”

Should you endure from the flush and you continue to wish to take pleasure in your favourite grownup beverage, Kenny suggests that you just drink slowly, keep hydrated and by no means drink on an empty abdomen. “The selection of alcohol may be essential,” he provides. “Avoid darkish drinks like purple wine which have tannin, which might additionally make you flush, and take a look at lighter drinks like [spiked] seltzer or vodka.”
