Basic Habitat/Botany:

China is one of the biggest producers.  In the U.S., Sacramento and San Joaquin Valleys in California produce 99% of the country’s English walnuts. The tree has a very deep taproot. Monoecious male flowers are slender catkins, while female flowers occur in short terminal spikes on current years shoots. Originated in Persia, then brought to Europe by the Romans. Black walnuts are native to North America. Walnut trees secrete the juglone toxin, which can extend for a 60 foot radius around the tree base and prevent some grasses and plants from growing.

Parts Most Frequently Used: Nuts, Shell Husk, Leaves, Bark and Root

Flavors: Leaf and Nut are Bitter and Pungent; Nut is also Sweet

Caution: None noted.

History/Folklore: Sleeping under a walnut tree is said to cause dreams about future events. Some people say that the branches protect against lightening. Romans called them “the glans of Jupiter” (glans being tip of the penis, or erectile tissue of the clitoris). In The Golden Age of Rome, it is said that men lived upon acorns while the gods lived upon walnuts. Women carried the nut to increase their fertility. Carrying the hard shell and wood gives the holder power, protection, and inner certainty, allowing that person to move forward with courage when faced with uncertainties.

Key Constituents:

Protein (very high in polyunsaturated fats compared to other nuts). Omega-3 fatty acids, potassium, high levels of phytonutrients, Vitamins A, D, E, B12, C, and B6, calcium, iron, and magnesium.  Melatonin occurs naturally in walnuts. Flavonoids, tannins and many other trace minerals.
