Barley

Barley plant
Description

Barley (Hordeum vulgare) is a common grain that is high in fiber. It's consumed in foods and used to brew alcoholic beverages worldwide.

The fiber in barley might lower cholesterol, blood sugar, and insulin levels. It also seems to slow stomach emptying which could keep blood sugar stable and help to control appetite.

People use barley for heart disease and high cholesterol. It is also used for colon cancer, diabetes, diarrhea, high blood pressure, obesity, and many other conditions, but there is no good scientific evidence to support these uses.


Is It Effective?

Effectiveness header

NatMed Pro rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

Likely effective
  • Heart disease. Eating 3.6 grams of barley daily as a source of dietary fiber seems to reduce the risk of heart disease.
  • High cholesterol. Eating 3-12 grams of barley daily seems to reduce total and low-density lipoprotein (LDL or "bad") cholesterol in adults with high cholesterol.
Possibly ineffective
  • Colon cancer, rectal cancer. Eating more barley as a source of fiber doesn't seem to lower the risk of developing colon or rectal cancer.

There is interest in using barley for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.

Is it Safe?

Drug interactions

Triclabendazole (Egaten)

Barley seems to reduce the amount of triclabendazole that the body can absorb and use. But it's not clear if this is a big concern. Until more is known, people taking triclabendazole should use barley with caution.
