Diabetes is a very serious condition. Don't ever try to treat it on your own with supplements.

People were less likely to have upset stomach and dry mouth. Binge drinking, however, is never safe or advised.

Prickly pear cactus may help with enlarged prostate symptoms. It may also lower unhealthy cholesterol levels. But we need more research to be sure.

Prickly pear cactus is a folk remedy for many other conditions, ranging from sunburn to ulcers to preventing mosquito bites. Some people use it on the skin to soothe big bites. However, we don't know if these uses actually work.

Can you get prickly pear cactus naturally from foods?

People eat prickly pear cactus in sautés, omelets, salads, and many other dishes. Raw, it tastes like watermelon. People also make it into:

  • Juices
  • Wine
  • Jellies

As a food, it's very common in Mexico.

What are the risks?

Tell your doctor about any supplements you're taking, even if they're natural. That way, your doctor can check on any potential side effects or interactions with medications.
