Fagopyrum acutatum also known as tall buckwheat, is a domesticated plant used medicinally, for animal feed, and as an ornamental plant. It is native to much of China, and to Bhutan, Nepal, India, Burma, and Vietnam.

The flowers are known for their high content of fagopyrin, a naphthodianthrone that provokes phototoxic effects known as fagopyrism.
