Allergic reaction

During an allergic reaction, the immune system breaks down and mistakenly identifies common foods or non-toxic substances as a threat to the body. After being exposed or eating nightshade vegetables, the body overreacts to the substances in the vegetables and starts to develop antibodies to fight off the allergen.

The presence of the antibodies can cause other chemical reactions that result to irritation and inflammation in the soft tissues. Histamine is the chemical produced by the soft tissues to protect the body from harmful substances. It can cause irritation and inflammation once released all over the body.

What are the types of skin reactions?

There are different skin reactions that can accompany an allergy to nightshade vegetables. Contact dermatitis is generalized itchiness and inflammation due to direct exposure to nightshade vegetables. Right after being exposed to the vegetable, the skin will become blotchy, irritated and inflamed as a response to the elevated histamine in the skin.
