Known as the Japanese raisin tree or Oriental raisin, Hovenia dulcis has been treasured in East Asian herbal medicine for centuries. In Traditional Chinese Medicine (TCM), it’s celebrated for its ability to “clear heat,” ease fatigue, and restore equilibrium after stress or overindulgence.
Modern research now echoes this wisdom—revealing that the Oriental raisin’s small, raisin-like fruits are rich in antioxidants and protective compounds that help support liver health, reduce inflammation, and promote overall vitality.

What is an Oriental Raisin?
Hovenia dulcis is a deciduous tree native to East Asia, producing clusters of small fruits that ripen into brown, raisin-like nodules. Traditionally dried and brewed into teas or tonics, the fruit has long been valued as a replenishing remedy—both a symbol and a source of renewal.
Though Hovenia dulcis belongs to the buckthorn family (Rhamnaceae), it isn’t related to sea buckthorn (Hippophae rhamnoides). Despite the shared name, these plants come from entirely different botanical families — yet both have earned reputations as restorative tonics.
History & Traditional Use
Long used in East Asian medicine, Oriental raisin has been used to support liver health and detoxification thanks to its antioxidant-rich compound dihydromyricetin (DHM). In TCM, it’s classified as cooling and sweet, said to “clear liver heat” and harmonize Qi. Ancient physicians prescribed it for those experiencing fatigue, thirst, or headaches after overindulgence, a practice that continues in parts of China, Japan, and Korea to this day.
In Korean folk medicine, Hovenia dulcis is taken to restore hydration and vitality, often steeped in hot water as a tea after celebrations or long days. Beyond hangover relief, it has been traditionally considered a general tonic for the liver, digestion, and circulation, helping to refresh both body and mind.
The Health Benefits of Oriental Raisin
1. Liver Detoxification & Protection
The liver plays a central role in filtering and neutralizing toxins, and Hovenia dulcis has been used for centuries to support this process. Modern studies have identified compounds in Oriental raisins such as dihydromyricetin (DHM) and hodulcin, which may help protect liver cells, regulate liver enzymes, and assist in detoxification.
By supporting healthy liver function, Oriental raisin can aid in the body’s natural recovery and detox—whether from alcohol, environmental toxins, high fat diets, or daily wear and tear.
2. Antioxidant & Anti-Inflammatory Support
The Oriental raisin fruit is rich in flavonoids and polyphenols that help defend against free radicals and calm chronic inflammation. These antioxidants support cellular repair, promote circulation, and help maintain long-term vitality.
Studies in rats suggest that these same compounds may have an effect on liver inflammation by supporting metabolic health.
3. Metabolic & Digestive Health
In both traditional and modern contexts, Oriental raisin has been used to aid digestion and promote metabolic balance. Its gentle sweetness and fiber content has been known in TCM to stimulate digestive enzymes, while its plant compounds are speculated to support healthy lipid and glucose metabolism.
Some modern research points to benefits for blood sugar regulation and fat metabolism—making it a quiet ally for balanced energy and digestive harmony.
4.Cognitive & Neurological Support
Since the Oriental raisin tree’s fruit extracts are rich in antioxidants that fight free radicals, which can damage brain cells, it’s been touted as good for the mind. Specific compounds in Hovenia dulcis, such as (-)-catechin and (+)-afzelechin, have been shown to protect neurons from toxicity caused by glutamate, according to one study.
There is also the potential for neuroprotective effects, helping to reduce oxidative stress in the brain and support recovery from fatigue or overindulgence.
5. Hydration & Rejuvenation
In TCM, Hovenia dulcis is considered cooling and replenishing, helping to restore fluids and combat thirst after alcohol consumption, exertion, or dehydration. It’s often used in formulas designed to revive energy, calm internal “heat,” and bring the body back to equilibrium.
