Orixa japonica

Orixa japonica, commonly called East Asian orixa or Japanese orixa, is a deciduous shrub growing to 3 metres (10 ft) with an equal spread. Native to Japan and South Korea, it is found on forested, sunny slopes at elevations from 500 to 1300 m. A recent scientific study found this plant to contain previously unknown alkaloids that may be effective against Plasmodium falciparum, one of the protozoan species that cause human malaria.
