Walnut

(Juglans regia)

History shows that the walnut tree has been established in Europe for a very long time and is one of the most well-known useful plants of all. The shape of the walnut is somewhat reminiscent of the shape of a human brain, which fits well with its property as a performance-enhancing raw material.

The name “Walnuss” (from Middle High German welsch nuz) originally means “welsch” (meaning “coming from the Romans”) nut.
