Science Shows Sage Heals

 

 

 

If you had turkey or chicken last Christmas it’s likely sage was a key ingredient for your stuffing. If you have some sage left over you may be surprised to hear how it can be used not only as a food flavour, but also as a medicine.

 

Sage's botanical name is Salvia officinalis, and from ancient times it has been used as a medicine. In recent years scientific research has explored the ways sage can be used to heal. The components of the herb which make it work medicinally are called the active constituents. The way a herb is prepared effects the availability of those active constituents to the body. So a tea will make some active constituents available, while other active constituents are more available in a liquid extract, and others in an extract of oil.

 

Medicinally Sage can be used in many ways; including the inclusion of the fresh herb in food, dried as a tea, in tablet or capsules, as a fluid extract and as an oil infusion. Additionally, the essential oil of Sage has been shown to have Antimicrobial and Antioxidant properties [1, 2]. Traditionally used to heal in many skin diseases, recent research showed the sage essential oils are antifungal and anti-inflammatory [3].

 

The liquid extract and essential oil of Sage has been shown to help improve memory [4] and is being studied to help prevent and delay the decline of the brain in dementia [4, 5]. I wonder if there is a connection here to the word “Sage” to describe a person of great age wisdom.

 

Many herbal medicines are currently being researched to find out how much they help to lower or stabilise blood sugar levels, as high blood sugar levels are a problem in Diabetes. Reducing excessive blood sugars helps prevent type 2 diabetes, and helps manage diabetes. Sage leaves or Sage tea does lower blood sugar levels [6, 789], and have been cited as having an effect like Metformin [7] which is a pharmaceutical medicine used to help people with Type 2 diabetes. Although some researchers believe Sage is mainly used to help prevent Type 2 diabetes [7].

 

Sage is also effective in helping decrease excessive sweating. This is especially useful for women who suffer from hot flushes at menopause [10]. Use a few leaves of fresh garden Sage or 1 teaspoon of dried leaves to make sage tea, let the tea brew for at least 10 minutes, then drink hot or cold. For help with hot flushes it is best sipped cold; 2-3 cups a day generally gives relief.
