Most people associate walnut trees with the delicious nuts they produce. Botanically speaking, the walnut tree’s fruit is actually not a nut but a drupe. The nut is actually the seed of the walnut tree’s fruit. The walnut’s fruit has an outer fleshy green husk surrounding a hard shell that contains the seed (which we call walnut). A whole walnut resembles the appearance of a brain.Altuntaş, H.; Duman, E.; Kılıç, G. Juglone induced oxidative and genotoxic stress in the model insect Galleria mellonella L.

It’s like a spa treatment for free in your own home. Walnut leaves and hulls can also act as a temporary brown hair dye.
