Sage Herb has also been shown to improve a range of health conditions. Herbs are gaining popularity in cooking and for their health benefits. Herbs are rich sources of natural antioxidants and have been used in cooking, flower displays and traditional medicine to manage and treat many health problems.
We’ll be discussing what the science says about sage and its health benefits. But firstly, let’s look at what sage is.
What is Sage?
Salvia officinalis, or sage as it is commonly called, is an evergreen plant that has been around a long time. It has a woody stem, green leaves, and purple flowers.
Sage is a member of the mint family, Lamiaceae. It is native to the Mediterranean region, although it can be found all around the world. Sage is a nutritious herb.

Health Benefits of Sage Herb
The following are the top 6 health benefits of sage.
1. Anti-inflammatory Properties
Inflammation is a natural body response to injury. Inflammation serves to heal infections and injuries. If left untreated, inflammation can cause ill health.
2. Improves Diabetes
Diabetes is a medical condition in which the body has difficulty producing enough of the hormone insulin which is needed to break down sugar in food. High levels of glucose in the blood if left unmanaged can cause a number of other health issues.
Eighty individuals took part in a good quality human study to see if sage provides health benefits in people with diabetes. The blood sugar (recorded 2 hours after eating) and cholesterol levels significantly decreased in the participants taking sage 3 times a day for 3 months compared to control group (4).
Another good quality study of 40 people with diabetes discovered that sage lowered fasting glucose, HbA1c, total cholesterol, triglyceride and LDL cholesterol, but increased HDL cholesterol (5).
Sage may be safe and have blood glucose and blood fat lowering effects in people with type 2 diabetes, high cholesterol and high triglycerides.
3. Decreases Bad Fats in the Blood
Hyperlipidemia, or high amounts of fats in the blood, is a common metabolic disorder affecting heart health. Sixty-seven individuals with high cholesterol and/or high triglycerides participated in a study to see the effect of sage on their heart health.
This well-designed study found that taking sage leaf extract at the dose 500 mg every 8 h for 2 months decreased cholesterol, LDL cholesterol and triglycerides and increased HDL cholesterol compared to the placebo group (6).
4. Alzheimer’s Disease
Alzheimer’s disease (AD) is a disease that gets worse over time. It affects memory and brain function. People with Alzheimer’s Disease using Sage as a treatment showed a slight improvement in brain function at 4 months when compared to the control group with moderate Alzheimer’s disease.
Sage may also reduce agitation in people with Alzheimer’s Disease (7). In another study, 20 individuals aged 65 years and older, received 4 types of treatment (167, 333, 666 and 1332 mg of sage) and a placebo with a 7-day wash-out period between visits.
On study days, treatments were given after a baseline assessment and at 1, 2.5, 4 and 6 hours post-treatment. The 333mg dose was associated with an increase in memory performance at all testing times. The other doses also had benefits, but to a lesser extent. There were also significant improvements in attention after the 333mg dose (8).
Sage has also shown to be beneficial in younger individuals. The 50 microl dose of sage (Salvia essential oil) significantly improved immediate word recall (9).
5. Anti-cancer Effects
An animal study showed that sage treatment had a chemopreventive effect on colorectal cancer. Sage minimized the occurrence of colon cells turning into cancer cells (10).
6. Menopause Treatment
Sage has been used traditionally to treat menopause and its symptoms. Menopause is the period in a woman’s life when menstruation stops. It usually occurs between the age of 45 to 50 years.
A range of undesirable symptoms such as hot flushes can be experienced. A study assessed the suitability of sage to treat hot flushes. One tablet per day was given to 71 women with the average age of 56 years old for 8 weeks. Researchers noticed that there was a positive change in intensity and frequency of the hot flushes. Sage officinalis showed promising signs in the treatment of symptoms such as hot flushes (11).
Sage is a herb that has been used for its health benefits for thousands of years. Sage is gaining popularity in the scientific field as scientists try to understand its health benefits and mechanisms of action.
In early studies, sage has been shown to have anti-inflammatory properties, improve the health of people with diabetes, high cholesterol, high triglycerides, Alzheimer’s Disease and cancer. Sage is showing promising health outcomes. More good quality human studies will help to confirm its effectiveness in treating specific health conditions.
In the meantime, feel free to enjoy a cup of sage tea and use sage in cooking. Consult your doctor before attempting to treat specific medical conditions, including cancer.
Even though sage is natural, it has the potential to interact with your medical conditions and the medicines you take and impact upon your other health needs.
