Plant history & usage:
The Japanese Raisin tree is a hardy tree found in Asia, from eastern China and Korea to the Himalayas where it grows at altitudes up to 2,000 m above sea level.
The fleshy, sweet, and fragrant fruits are eaten raw or cooked. When the fruits are dried, they acquire both a taste and appearance reminiscent of raisins.
An extract made from seeds, branches, and young leaves can be eaten like honey and is also used to make wine and candy (Facciola, S.).
The seeds contain about 15% protein and 7.8% fat (Duke. J. A. & Ayensu. E. S.).
The Raisin tree has long been used in traditional Chinese, Korean, and Japanese medicines to treat a variety of ailments, including hangover (Hyun TK et al.). The fruits of the Raisin tree are already mentioned in materia medica from the Tang dynasty in the 7th century.
Modern research confirms that the flavanonol ampelopsin / dihydromyricetin (DHM), found in plants of the genera Ampelopsis and Cercidiphyllum, can reduce symptoms of alcohol poisoning and withdrawal (Reich L.).
Extracts of Hovenia dulcis are commercially available and marketed as a remedy for the aftereffects of excessive alcohol consumption.
The tree is traditionally known for its health benefits when consumed as tea.
The wood from the Raisin tree is hard and well suited for furniture making.
Cultivation:
Thrives well in well-drained, sandy loam soils in sunny and warm locations. Preferably protected from frost during the first years, thereafter the tree tolerates down to -15°C. However, if the tree is slowly hardened against the cold, the tissue can mature (harden) and then the tree can be hardy down to -25°C (Huxley. A.).
Avoid compact and wet soils.
The tree is considered fast-growing and usually does not exceed 5-6 meters in height in our climate. In other parts of the world, it can reach heights up to 30 meters.
Can be topped to be kept as a shrub or allowed to grow to become more naturally tree-shaped.
The Raisin tree is drought-tolerant, but the quality of the fruit can be noticeably affected if water supply is insufficient. Watering 2-3 times a week is recommended during spring and summer.
The fruits usually ripen late in the season, around October. The fruits are harvested when dried on the tree, so no need for manual drying of the fruits.
The Raisin tree is self-fertile and produces abundant fruit when mature.
