Sage’s genus name, Salvia, means “to heal,” and thus reflects on its early use as a medicinal herb. It is a member of the mint family of plants, and ia closely related to rosemary.
Sage is known for its natural preservative, antiseptic and bacteria-killing abilities in meat. Volatile oils, which are distilled from the blossoms contain the phenolic flavonoids diosmetin, apigenin, luteolin, and volatile oils such as rosmarinic acid, which can be absorbed easily into the body.
Health Benefits of Sage:
1. Anti-Ageing Properties
The antioxidants present in sage reverse the signs of ageing such as fine lines, wrinkles and age spots. These antioxidants provide protection against free radicals, which causes damage to skin cells, causing premature ageing of your skin.
This herb is filled with vitamin A and calcium, which protect your skin against the assault of free radicals and help in daily cell regeneration, therefore delaying and minimizing the onset of facial wrinkles.
2. Bone Health
One of the most overlooked benefits of sage is its beneficial benefits for bone health. Due to its superior level of vitamin K, which is an important vitamin for the body that is not found in many common foods.
Vitamin K is an important element in developing bone density and in ensuring the integrity of your bones as you age. If you are suffering from early signs of osteoporosis, have lived a rather nutrient-poor and sedentary lifestyle, then your bone health is likely low. Adding sage leaves into your diet can help in increasing your vitamin K levels significantly, because a single serving contains 27% of your daily recommended intake.
3. Diabetes Prevention
Several studies have proven that sage leaf extract contains anti-hyperglycemic properties which can help in lowering blood glucose levels through the blocking of the release of stored glucose from the liver. It is effective in lowering triglyceride and cholesterol levels in type 2 diabetics. But, further research is needed to substantiate this claim.
4. Relieves Menopausal Symptoms
In study conducted in 2011, researchers Bommer, Klein and Suter reported that taking fresh sage leaf tablets can significantly decreased hot flash symptoms in half of the participants after just 4 weeks.
In 8 weeks, 64% benefited from the treatment with decreased hot flashes weekly and very severe flashes were eliminated. Also, a 1997 survey that was conducted by the National Institute of Medical Herbalists (NIMH) in the U.K., indicated that the majority of member practitioners prescribed sage to patients for the treatment of night sweats and hot flashes from menopause.
5. Treatment for Alzheimer’s
A current review of studies have shown that species of sage could impact cognitive skills and protect against neurological disorders.
The study author said that:
“In vitro, preliminary human and animal studies have supported the evidence of Salvia plants, in enhancing cognitive skills and guarding against neurodegenerative disorders.” Other studies have reported that sage can also help in improving memory in young, and healthy adults.
Further research is required, as most studies have been conducted on 2 species of sage, S. lavandulaefolia and Salvia officinalis (S. officinalis).
