Hyperlipidemia, or high cholesterol, puts an individual at risk for heart disease, the leading cause of death in the United States (2). There are rarely physical symptoms associated with hyperlipidemia, so individuals often do not realize they have high cholesterol levels (2). Currently, 71 million US adults have high LDL, or “bad” cholesterol (2). Due to the side effects of cholesterol medicine and the fact that only 1 out 3 adults are well controlled on medication, research is looking at alternative options (2). Recent research has found that supplementing with sage is an effective option in lowering cholesterol levels (1).
Sage, or Salvia officinalis, is most commonly known as an herb for adding flavor to food (1). ranian folk medicine uses sage for both hyperlipidemia and hyperglycemia (high blood sugar) (3). Previously, there has only been one pilot study with sage. In the study, drinking sage tea was found to improve cholesterol levels in 6 healthy women (4). For this reason, researchers wanted to look at a larger study population to determine if supplementing with sage would have a similar effect.
The research included 67 participants with an average age of 56.4 +/- 30.3 years. The participants were randomly divided into either the sage treatment group (n=34) or placebo group (n=33). The sage group took one 500mg capsule of sage extract every 8 hours for 2 months (1).
After 2 months, the following improvements were observed in the sage treatment group:
Average Before | Average After | Percent Change | P-value | |
---|---|---|---|---|
Total Cholesterol | 266.3 +/- 41.6 | 211.3 +/- 31.7 | Decreased 19.6% | <0.001 |
Triglyceride | 296.7 +/- 24.3 | 227.7 +/- 15.1 | Decreased 22.8% | <0.001 |
VLDL | 58.2 +/- 16.2 | 47.6 +/- 10.7 | Decreased 13.3% | 0.001 |
LDL | 151.8 +/- 52.2 | 117.5 +/- 37.8 | Decreased 19.7% | 0.004 |
HDL | 49.2 +/- 8.2 | 57.6 +/- 6.6 | Increased 20.2% | <0.001 |
The above data shows that all markers of cholesterol improved in the sage treatment group (1). There were no significant changes in the placebo group (1). There were also no adverse effects reported by either group (1).
In conclusion, sage leaves may be an alternative option for the treatment of hyperlipidemia. The research showed improvement in all cholesterol markers with sage supplementation. Future research with more participants should be conducted to confirm these results (1).
