What Are Nightshade Plants?

The mere words Nightshade Plant draw up images of mysterious workings within the dark of night, images of witches and of medicine men silently creating their wares, the creation of magic potions or poisonous concoctions.

Well the images and ideals surrounding Nightshade Plants may not be that far off from the truth. Many of these sprouts, herbs, and vegetables contain ingredients that are used within modern and herbal medicines.

Although these plants and their chemical components are generally used to promote good health some of their properties can indeed be toxic when consumed in large quantities or when given to people who have a food sensitivity or autoimmune disorder.

Nightshade plants are more common than one might first presume. Many people do not realize that some of the foods growing in their garden fall under this category and may not be all that healthy for some members of their family to consume.

Nightshades are plants which have developed a means of self defense against predators who may wish to consume them. These predators generally being small creatures such as bugs or insects but may also include larger creatures such as grazing animals and we humans.

The deadly nightshade plants are fortunately really not as scary as the term sounds unless you are an insect that is. They produce a toxic substance to protect themselves from being eaten but this poison is in small amounts so usually only extremely harmful to very small creatures. Unfortunately the toxins within these plants can be sufficient enough to cause a reaction in sensitive individuals so they are indeed a food source which it is wise for some people to avoid.

Most of us know that the tobacco plant is not good for us because it contains a little chemical that we all know by the name of nicotine. What most people do not realize is that other nightshade plants such as eggplant and tomato also contain this same chemical. These toxic compositions are why most allergies to this food group occurs. 

This plant species have developed a protective defense mechanism to keep insects from consuming them. They produce alkaloids, a nitrogen containing structure that is designed to poison the offending insect and keep it from feeding on the plant.

This includes such foods as Pimentos, Paprika, Cayenne pepper, and Tabasco sauce.
Plant Alkaloids and Why They Can Cause a Food Sensitivity

Health effects from the consumption of these can result in joint or nervous system disorders, digestive problems, loss of calcium in bone or increase of calcium in soft tissue, as well as other health related problems.

This is why sensitivities to the nightshade family of plants are quite common. The people who ingest members of the nightshade family consume the very alkaloids that the plant produces to ward off offending insects. They eat the very poisons that these sprouts produce to keep itself from being consumed.
