Fagopyrum Esculentum

This week, I studied Fagopyrum Esculentum, otherwise known as Buckwheat. This plant was originally tagged for me as toxic by the USDA website. It was really surprising to find out that it is known as Buckwheat and is used for purposes for human consumption. Not only is it high in nutrients, but it is also flavorful. “So, why is this classified as toxic?” said I. Well, it turns out, the plant is toxic, but the ripe seeds are not toxic! The ripe seeds are the parts that are used for making buckwheat flour. The plant itself, on the other hand, contains Fagopyrin. This chemical reacts to ultraviolet rays when it is already inside the body! This happens particularly in non-pigmented skin. It irritates the blood vessels and it sometimes takes up to three months to recuperate. In this picture, you can see the effects of the Fagopyrin chemical on the non-pigmented parts of the horse but not on the pigmented, brown, areas.
