Manchurian walnut (dumbey) is a deciduous monoecious tree or shrub belonging to the genus Walnut.

Description and distribution locations

The Dumbay nut is a close relative of the walnut. Under natural conditions, it grows into a tall tree, about 25-30 meters, with a spreading crown. In open places, the trunk is lower, and the crown forms a tent, expanding in breadth. In this form, the tree can become a decoration for any garden, as well as perfectly protect from sunlight and rain.

Dumbey nut grows in Primorye and Amur Region, in the west it reaches the Zep River. Prefers mixed forests, grows in river valleys and on adjacent slopes. The tree is successfully bred in Novosibirsk, Gorno-Altaysk and a number of other settlements.

The Manchurian walnut has complex odd-pinnate leaves, up to 70 cm long. They consist of 5-9 leaves and have a strong odor that repels moths.

The tree blooms in May, simultaneously with the opening of the leaves, forming on the branches short brushes up to 12 cm with female flowers, and earrings up to 15 cm long with male flowers.

The tree begins to bear fruit at 6-9 years of age. The fruit is an oval green drupe up to 5 cm long. Inside the green pulp there is a hard shell, and in it there is an oily seed - the kernel of the nut.

The chemical composition of the Manchurian nut

The properties of the Manchurian nut are due to the content of nutrients in it. Young leaves of the plant contain tannins, iodine, alkaloids and essential oil, as well as a lot of ascorbic acid (about the same as in rose hips). In the pericarp of the nut, tannins are found that contain hydrojuglons (substances that can have a beneficial effect on certain skin diseases).

The kernels contain 50% fatty oil.

Healing properties
