The black walnut tree, a member of the walnut family, graces the eastern part of North America and sprawls across the majority of the United States east of the Rocky Mountains. This robust deciduous giant earns its name from the black walnuts it bears, a process that kicks in around its 5th or 6th year of growth.
Scientifically labeled Juglans nigra, the black walnut tree made its way to Europe as early as the 1600s, gaining popularity for its higher unsaturated fats and protein content compared to the English walnut. Beyond being delicious, this culinary gem is used in an array of confectionery goods, salads, meats, and candies, showcasing its versatility.
Uses: Apart from culinary prowess, the black walnut boasts a husk that holds promise for various ailments. Though not definitively proven by modern trials, many still turn to black walnut husks as an anti-parasitic agent for the digestive tract. The drupes also serve as a source for valuable dye, while the tree's wood stands as one of North America's most sought-after for its pure, beautiful heartwood.
Benefits: Health-wise, black walnuts have earned their stripes for promoting a healthy digestive tract. They are associated with eliminating Candida fungus and fungi causing Athlete’s foot and ringworm. A tincture of black walnut extract finds use in treating skin conditions like acne, eczema, and psoriasis.
The concentration of unsaturated fats and organic acids in black walnuts bring positive antioxidant and wound-healing effects, contributing to clearer skin. Moreover, they play a role in enhancing heart health by reducing LDL cholesterol levels and lowering blood pressure.
Caution: While not a common allergen, those with other nut allergies should consult their doctor before diving into black walnuts. Caution is advised against regular skin application, as it may lead to toxicity and increase the risk of lip or tongue cancer. Though an extreme side effect, care should be taken before making it a regular part of one’s diet.
Other Info:
To access the prized nut, black walnuts must be cracked open. After harvesting, it's best to shell them immediately to maintain color and taste. A thorough wash to remove debris, followed by drying and storing in a plastic bag in the freezer, ensures long-term use. Proper storage is key to preventing the oils in the nuts from going rancid. So, when dealing with these remarkable nuts, mind how you store them!
