Fallopia multiflora and Polygonum multiflorum) is a species of flowering plant in the buckwheat family Polygonaceae[1] native to central and southern China.

The flowers are 6–7 mm (0.24–0.28 in) diameter, white or greenish-white, produced on short, dense panicles up to 10–20 cm (3.9–7.9 in) long in summer to mid-autumn.

[2] In Chinese folklore, it is believed that the root of he shou wu (何首烏, Reynoutria multiflora) can, after a thousand years, transform into a human form, either as a child or an old person.

The following day, she traces the thread and finds it attached to a he shou wu root, from which a human shape is growing.

[11] More than 100 chemical compounds have been isolated from Reynoutria multiflora, and the major components have been determined to be stilbenes, quinones, flavonoids, and others.
