|Cultivation Status||Cultivated, Wild
Grows well in a fertile sandy loam in a sunny position[
]. Succeeds in full sun to moderate shade, tolerating a wide range of soils so long as they are well-drained.
The fruiting rachis is thick, rich in sugar, and edible[
]. It is also used for making wine and sugar[
The fruiting rachis is used medicinally[
]. No more details are given, but the uses are likely to be the same as for the closely related Hovenia dulcis - these are as follows:-
Both the fruits and the fleshy peduncles are considered to be antifebrile, diuretic, hepatic, laxative and quieting to the stomach[
]. Remarkable antivinous properties are also attributed to them - it is said that after the ingestion of large quantities of alcohol the use of this drug will prevent any intoxicant or poisonous action[
Research has shown that the plant has an effect on reducing blood sugar levels and also exerts a protective influence over the liver - it is most effective if taken 30 minutes before the ingestion of alcohol (when it can reduce levels to 17% of control), though it is also somewhat effective if taken at the same times as alcohol (to 50% control levels), and also has some effect if taken after alcohol.
The fine, hard timber is good for building construction and making fine wood furniture[
Seed - germinates freely if sown as soon as it is ripe in a cold frame[
]. Stored seed should be scarified and sown in early spring[
], it may not germinate for a year. Prick out the seedlings into individual pots when large enough to handle and grow on for at least their first winter in a greenhouse. Plant out in late spring after the last expected frosts and give some winter protection for their first couple of years outdoors.
