As well, you should not feed most vegetables that are in the pepper or nightshade family to your horse. Although humans enjoy eating foods that are in the nightshade family because of their flavors, bitterness, and spiciness, horses are not able to handle these foods in their system. Their bodies are unable to break the chemicals that are in nightshade plants.

Eating peppers or anything in the nightshade family is so bad for horses that they can develop colic and laminitis from peppers.

What Should I Do if My Horse Consumes Peppers?

They will have stomach cramping and nausea throughout the night, but in the morning, they should be fine. Although they may be tired from not sleeping very well. However, if your horse has been consuming peppers for a while, you will need to call the vet asap, even if they are showing any signs of pain or distress.

If you find out that the area where your horse grazes has peppers grilling and they have been eating the peppers and their leaves and stems for a while, you will want to have the advice of a veterinarian. You’re more likely to call the vet because of their behavior. Your horse will show obvious signs that they are in pain. 

When you contact your horse’s vet, tell them that your horse has been eating peppers. When a vet knows that a horse is in danger of nightshade/solanine poisoning, they can react faster and supply the affected horse with the right medicine.

What Foods Are in the Nightshade Family?

Surprisingly, there are several vegetables that humans consume every day that are in the nightshade family. Some you would not even expect. There are even some spices that are part of the family as well. Most popular nightshade vegetables you can easily find our russet potatoes and all potatoes in general, all varieties of tomatoes, eggplants, all varieties of green bell peppers, the tomatillo, the Goji fruit, ashwagandha, pepinos, paprika, and cayenne pepper.

Don’t forget that horses who frolic and play in fields and forests can come across the deadly nightshade plant. One bite of this plant and your horse will suffer in pain for weeks, losing weight as it won’t be able to eat and losing its will to even stand as its strength is zapped away. If your horse eats the entire nightshade plant, it will eventually die after experiencing excruciating pain. It is from this plant that all nightshade vegetables and spices get their toxins.

But what are in nightshade plants that make them so toxic to horses? 

There is an alkaloid compound called solanine. Much like foods in the nightshade family have a peppery taste and burn the tongues of humans that eat them, solanine in flames the digestive system, muscles, and joints. Solanine affects the horse’s body by forcing perfectly healthy cells to die prematurely.

Other symptoms that show a horse has ingested solanine are: difficulty breathing, loss of strength, dilated pupils, antisocial behavior due to pain and stress and legs weakening, and slowly paralyzing.

The concentration of solanine in nightshade vegetables like tomatoes and peppers is nowhere near the same amount as if they are in the actual deadly nightshade plant. If the levels were similar, even humans would not be able to eat the vegetables. However, any amount of solanine is terrible for a horse. They have very low tolerance, much lower than a human’s. But there are even some humans whose doctors advise them to stay away from plants in the nightshade family because of stomach pains the plants’ cause.
