Since we launched our "Ultimate Energy Rescue — Hovenia B-Complex," many customers have encountered the name Hovenia dulcis for the very first time.
It doesn't roll off the tongue the way Vitamin B or turmeric does. But in the world of Traditional Chinese Medicine and East Asian herbal history, this fruit has been quietly doing its job for over a thousand years — even earning itself a legendary nickname: "The Secret to Never Getting Drunk."
Why did ancient healers think so highly of it? This isn't folklore. It's documented wisdom.
1. What Li Shizhen(李時珍）Wrote: Could It Actually Neutralize Wine?
In the Bencao Gangmu (Compendium of Materia Medica) — one of the most authoritative texts in Traditional Chinese Medicine — the renowned physician Li Shizhen described Hovenia dulcis (also known as raisin tree or chicken claw tree) in vivid, almost mythical terms.
One of the most famous passages goes like this:
"A man from the south once used this wood to build a house. A small chip accidentally fell into a jar of wine — and the wine turned to water."
He went on to note:
"If the wood is used as a pillar, the wine brewed nearby will lose its taste and potency."
Now, these accounts are clearly written with a poetic flair — but they point to something very real: in ancient medicine, Hovenia dulcis was understood to have a powerful relationship with alcohol. It was considered nature's antidote to intoxication.
The Tang Bencao also records its use for "headaches, abdominal tension, excessive thirst, and restlessness" — symptoms that map almost perfectly onto what we'd call a hangover today: dry mouth, headache, nausea.
2. From Legend to Lab: What Modern Science Has Found
Ancient healers knew what it did. Modern science has helped us understand why.
When researchers analyzed Hovenia dulcis, they identified two key active compounds: Dihydromyricetin (DHM) and a range of alkaloids.
Here's what happens when alcohol enters your body: it's first converted into a toxic substance called acetaldehyde — the real culprit behind flushing, headaches, and that miserable hangover feeling. The body then has to work to break that down into harmless acetic acid and water.
According to modern pharmacological research, Hovenia dulcis extract works by:
1. Speeding up metabolism — It supports the activity of two key enzymes: alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). In plain terms, it helps your body process and clear alcohol byproducts faster.
2. Providing a protective effect — It helps reduce the direct impact of alcohol on your body's normal functioning.
This explains exactly why ancient people felt like "the wine just disappeared." It didn't vanish — the body simply became much more efficient at handling it.
3. Clear the Path First, Then Refuel: Why We Paired It with B Vitamins
This is the exact reason we chose to include premium Hovenia dulcis extract alongside the B-vitamin complex.
Modern exhaustion often isn't just about lacking nutrients — it's about being overloaded.
Traditional B vitamins deliver energy — like adding fresh fuel to an engine.Hovenia dulcis clears the metabolic pathway — like cleaning out the buildup that's been blocking the engine from running properly.
Without Hovenia dulcis clearing the way, the effectiveness of B vitamins can actually be bottlenecked by metabolic waste like acetaldehyde still lingering in the system. This combination is the best proof of what happens when ancient herbal wisdom meets modern biotechnology.
