Overview Information

Dragon fruit is the fruit of a kind of cactus that grows in dry areas of South America. Usually the skin of the dragon fruit is red and the pulp is red or white. Dragon fruit is sometimes used as medicine. The fruit is also popular as a food.

Dragon fruit is used for diabetes, prediabetes, high blood pressure, high cholesterol, obesity, and many other conditions, but there is no good scientific evidence to support these uses.

Dragon fruit can be eaten raw or made into wine, juice, spreads, or desserts. The flowers are sometimes eaten as a vegetable or made into a tea.

In manufacturing, the peel of the fruit is used as food coloring and as a thickener.

How does it work?

Dragon fruit contains chemicals which act as antioxidants. These compounds might help protect the body.


Uses & Effectiveness?

Insufficient Evidence for

  • Diabetes. Some early research shows that taking dragon fruit does not lower blood sugar levels in most people with type 2 diabetes. But more research is needed to see if higher doses might be beneficial.
  • Prediabetes. Early research shows that dragon fruit can lower blood sugar levels in most patients with prediabetes. Higher doses seem to be most effective.
  • Cancer.
  • Heart disease.
  • High blood pressure.
  • High cholesterol.
  • Obesity.
  • Wound healing.
  • Other uses.
More evidence is needed to rate the effectiveness of dragon fruit for these uses.
Side Effects

Side Effects & Safety

When taken by mouth: Dragon fruit is LIKELY SAFE when eaten as a food. There isn't enough reliable information to know if taking dragon fruit as medicine is safe or what the side effects might be. Some people might be allergic to dragon fruit.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if dragon fruit is safe when used in medicinal amounts when pregnant or breast feeding. Stay on the safe side and stick to food amounts.

Diabetes: Dragon fruit might lower blood sugar levels. If you take dragon fruit, monitor your blood sugar levels closely.

Surgery: Dragon fruit might interfere with blood sugar control. Stop taking dragon fruit at least two weeks before a scheduled surgery.
