What is naringin?

Naringin belongs to a category of chemical compounds known as flavanones, which are a type of flavonoid.

Flavanones and other flavonoids impact the taste and color of different plants. They also help plants protect themselves against diseases and harmful insects.

Naringin is most commonly associated with citrus fruits, including:

  • Grapefruit
  • Lemon
  • Orange
  • Pomelo

Grapefruit contains especially high amounts of naringin, which gives the fruit its bitter taste.

However, some other plants also contain the flavanone in smaller amounts, such as:

  • Tomatoes
  • Sour cherries
  • Cocoa
  • Greek oregano
  • Cannabis

Naringin is also commonly used as:

  • A flavoring agent for foods
  • A fragrance for scented cosmetics and other products
  • An ingredient in pharmaceuticals
  • An ingredient in livestock feed to improve the health of animals

Naringin benefits

Research has shown that naringin may offer some health benefits. But more studies are needed to confirm its positive effects on health.

Lowers inflammation

Naringin may have anti-inflammatory effects, according to a review article. Researchers found that it may help reduce inflammation in many parts of the body, including the:

  • Joints
  • Liver
  • Brain
  • Skin
  • Lungs

Protects liver health

A rat study found that naringin may help prevent liver damage and injury caused by exposure to toxic substances. Researchers found that naringin may help reduce inflammation, cell damage, and fibrosis in liver tissue.

Reduces cancer spread

Researchers have found that naringin may help prevent the progression of cancerous cells and tumors. Findings from a narrative review suggest that the flavanone helps lower inflammation in the body that may otherwise promote cancer spread. The study also suggests that naringin supplements might help make chemotherapy more effective.

Prevents metabolic syndrome

One study found that naringin helped improve diet-induced metabolic syndrome in rats. Rats that were fed a diet high in fats and carbohydrates but given naringin supplements showed improvements in fatty liver, insulin resistance, and high blood pressure.

The study also suggests that, because metabolic syndrome can lead to heart disease, naringin may help protect heart health.

Improves bone health

Naringin may increase the activity of bone cells to promote bone formation, according to a cell study.

Naringin flavonoid in cannabis

Naringin is one of about 20 flavonoids found in cannabis. The cannabis plant contains only trace amounts of naringin. As a result, no high-naringin strains are available.

Naringin side effects

Some people have reported side effects after consuming pure naringin, such as:

  • Dizziness
  • Upset stomach
  • Flushed skin

However, the small amount of naringin in cannabis is unlikely to cause these side effects.

The bottom line: Naringin has several potential health benefits

Naringin gives certain plants a bitter flavor, and may be used to promote bone health, protect heart health, and lower inflammation in the body.

Although cannabis contains trace amounts of naringin, the flavanone still contributes to the plant’s potential health benefits. To learn more about how naringin and other flavonoids contribute to the effects of cannabis, schedule an appointment with a provider at Leafwell.
