Black walnut: useful properties and contraindications

Black walnut or black walnut is a plant that has spread around the world from the northern part of America. The appearance and sphere of use of its fruits does not differ from the walnuts familiar to many people.

Black walnuts are added to desserts, side dishes, cocktails and even sauces, which is possible due to their excellent taste characteristics. At the same time, the product will please not only with its taste. With its regular use you can notice its unique effect on the human body, which is explained by the content of this product of a large number of nutrients, including vitamins, macro- and microelements.

The benefits and harms of black walnuts

The homeland of the black walnut is considered the territory of modern North America. In Massachusetts, Florida, Texas and other states it can be found growing wild. That said, this plant does not need special conditions for successful fruiting and active growth. The tree can grow:

  • In forests;
  • Near small bodies of water;
  • In fertile mountain soil;
  • in park areas;
  • in alleys.

Since the middle of the 18th century, black walnut has been successfully cultivated in the Russian Federation as well. It can be found in regions with a warm climate, including Stavropol, Krasnodar Territory.

For Europeans black walnut is also not something unfamiliar and surprising. It can be found throughout Europe, with the exception of Scandinavia, whose climatic conditions are not suitable for its cultivation.

The appearance of the plant resembles that of a walnut tree. Agronomists distinguish only a few features characteristic of the black walnut:

  1. Bark color. The bark of the plant is colored in a chocolate brown shade.
  2. Tree height. Black walnut can reach 50 meters in height.
  3. Shape and diameter of the crown. The crown has a vaulted shape, and its diameter can reach a size equal to the height of the tree.
  4. Root system. The roots of such a nut are colored black and are of the rod type.

The first leaves on the tree appear in the period from mid to late spring, and flowering does not come until the seventh year of the plant's life. After that, fruits are formed on the tree, presented in the form of rounded nuts, with a slightly elongated front part, the diameter of which is no more than 5 cm. The nuts are covered with a four-necked shell and during their ripening period are in a peel, which can be from 5 to 10 mm thick. The edible part of the fruit is inside the shell and is presented in the form of a kernel, which has a specific aroma and a unique taste.

What is the difference between a black walnut and a walnut?

Both the walnut and the black walnut belong to the Walnut family, which explains why there are not many distinctive characteristics. The crown, trunk, leaves and even the fruit of these two plants are very similar, which makes them easy to confuse. However, a few differences can still be highlighted:

  1. Composition. The walnut and black walnut fruits contain aromatic substances, polyphenols and juglons. However, if you pay attention to their quantity, you can notice that in the black walnut these substances are much more.
