Sage May Help Improve Blood Sugar Levels

Sage is a staple herb with a strong aroma and earthy flavor. It is available in fresh, dried, or in oil form. This native plant has been used for a long time in traditional medicine for various diseases.  Its leaves are a well-known remedy against diabetes. Experts have found out that it may help lower down blood sugar levels in both human and animal studies (1).

Animal Study

In a mice study, results revealed that sage tea acts like metformin — a drug prescribed to manage blood sugar in people with diabetes (2).

In addition to this, a study in rats with diabetes showed that sage extract reduced blood glucose levels by activating a specific receptor thus helping get rid of excess free fatty acids in the blood, which in turn improves insulin sensitivity (3,4).

Human Study

In a study conducted on 80 individuals with poorly controlled type 2 diabetes, results demonstrated that sage has a positive effect on blood sugar levels. Individuals who took sage had experienced a significant decrease in their blood sugar levels after 2 hours of fasting (5).

In addition to this, a study involving 40 people with diabetes and high cholesterol had shown the following results after participants took sage leaf extract for 3 months: (6)

  1. lower fasting glucose
  2. lower average glucose levels over a 3-month period
  3. lower total cholesterol, triglyceride, and levels of harmful cholesterol
  4. had increased levels of HDL or “good” cholesterol

Due to these results, experts concluded that sage leaves have anti-hyperglycemic and lipid-profile-improving effects in hyperlipidemic type 2 diabetic patients.

Another study in 105 adults with type 2 diabetes found that taking 500 mg of sage extract 3 times daily for 2 months helped improve their fasting blood sugar, post-meal blood sugar, and hemoglobin A1c — a measure of average blood sugar levels over the previous 3 months (7,8).

How To Take Sage To Control Blood Sugar Levels

Have an aromatic sage tea at home to enjoy its benefits.


Simply bring 1 cup (240 ml) water to a boil and then add the sage (1 tablespoon of fresh or 1 teaspoon of dried sage). Steep for about 5 minutes. Strain to remove the leaves and then add some honey and lemon juice to taste. Consume hot or cold.
