Multiple studies have shown that extracts and oil from *Opuntia ficus-indica* have low toxicity, confirming the plant is not chemically poisonous. However, the plant's reputation for being dangerous comes from its formidable, hair-like spines and glochids that can cause painful skin irritation.

For thousands of years, indigenous cultures have relied on certain species of cacti as a food source. However, not all cacti are safe to eat raw, and improper handling can lead to painful injury from spines or illness from toxic varieties.

According to the University of Nevada, Reno Extension, both the pads (nopales) and the fruit (tunas) of the prickly pear cactus are edible, but require careful handling to remove spines. So, are nopales safe to eat? Yes, they are—and they are a nutritious addition to many meals—as long as you follow the correct preparation methods.

While the prickly pear's fruit is edible, its cousins are not so benign. Knowing what cactus should you not eat is crucial, as some species contain psychoactive or toxic compounds, and dangerous lookalikes can cause severe reactions.

While many cacti are known for their formidable spines, the **prickly pear cactus** is not inherently poisonous to humans or pets when properly prepared. It is a versatile and highly nutritious food source, but its spiky exterior necessitates careful handling to avoid painful physical irritation from its thorns and tiny barbed hairs.
