Black Walnut
Black walnut is botanically named as Juglans nigra. It comes under the walnut family which belongs to the flowering plant. Its native is near North America and extends up to Texas, Florida, Georgia, Southern Ontoria and in larger parts of Riparian sector. It is a largest tree in the forest which reaches nearly 30-40 meters height and a broad trunk with a wide crown which provides the shelter for many living beings. It is having the hard blackish grey colored bark which is completely crumpled. The leaves are pinnate in the odd form which counts nearly 17-23 in a single leaf.
The length of the leaf is around 7-10 cm and the breadth is approximately 3-5cm. Both male and female parts are isolated in the same flower whereas the male part occupies the entire flower with end of the stamens as female part. This combined form creates the pale green colored fleshy fruit in the late autumn with a crumpled nut inside. The seeds are comparatively very small and the entire fruit gets ripened and falls at the season of October. Most probably it is not a self pollinating plant and hence it requires one more plant for the reproduction of a new plant. Black walnuts easily get breaded with other species of the juglans genus.

Negative Role Of Black Walnut
Preferably the pregnant and breast feeding women are suggested not to take any of the products from Black walnut because of their allergic characteristics.
The presence of tannin is somewhat toxic. Intake of more walnut leads to complete absorption of food materials present in the stomach and intestine.
The juglones are mainly generated at the roots of black walnut, which are highly toxic to other plants nearer to its root system. Juglone is present in all the parts of black walnut which are comparatively less than the roots have.
Juglone mainly reduces the protein bonding in our body which seems to damage our DNA ligase and leads to prompt damages in our cell.
Prolonged consumption of black walnut leads to no side effects but when applied on the dry skin is not safe, because of the presence of a chemical named as juglone which is highly specified as an inducing agent for lip and mouth cancer.
It is a nut with high fat content in it and should be avoided by low fat diet people.
Possibly the walnuts should not be taken in whole, but less than twice is preferably good.
