What Are Sage Leaves?

Sage (Salvia officinalis) is a member of the ‘mint’ family (Lamiaceae). The plants have a unique aroma and pretty flowers in different colors. Many species of sage, including Salvia officinalis (common sage or kitchen/garden sage), are native to the Mediterranean region (1).

Sage was also used in ancient Egyptian, Roman, and Greek medicine. In fact, in Native American rituals, dried sage leaves are burned to promote healing, wisdom, protection, and longevity (1).

The leaves are an excellent reserve of essential oils and phenolic compounds. These are thought to be responsible for the herb’s medicinal value (1).

Based on their composition and origin, you have different types of sage, such as common sage, pineapple sage, and red sage. This wide variety makes sage one of the largest genera under the mint family.

What Are The Benefits Of Sage?

Sage has antiseptic, antimicrobial, and antioxidant properties. It boosts memory and controls blood sugar and cholesterol levels if used in optimal amounts.

1. May Boost Memory And Cognition

Several varieties of sage have been used to restore memory loss and cognitive decline, as mainly seen in Alzheimer’s disease. Similarly, it may also help with Parkinson’s disease. This decline in mental ability arises when neurotransmittersⁱ  Chemical messengers that carry chemical signals from neurons to the cells, supporting essential body functions. are degraded by your body’s specialized enzymes (1).

Acetylcholine, a neurotransmitter, is degraded by the enzyme acetylcholinesterase (AChE) in most brain disorders. Drugs and herbs that inhibit the activity of AChE are given to such subjects (1), (2).

The essential oils of sage have shown 46% AChE inhibition in lab trials. Its herbal extracts can protect the brain cells (neurons) from the effects of cholesterol accumulation and inflammation (amyloid ß- plaques) (1), (2).

2. May Combat Skin Aging

Studies suggested that sage and its compounds may help in combating skin aging.

Sage could also improve wrinkles through a photoimaging mechanism (3).

Sclareol, a compound from sage, is widely used as a fragrance material. Studies show that this compound inhibits the UVB-induced damage to the skin. It could also recover the epidermal thickness that was reduced by UVB rays. Creams with sclareol could improve wrinkles by enhancing cellular proliferation (3).

Trivia

A combination of sage leaf extract and rhubarb bark, when applied topically, is found to be helpful in treating herpes simplex labialis (15).

3. May Promote Hair Growth

Sage is rich in antioxidants that can help to prevent and reduce the formation of new gray hair. The natural oils in sage strengthen the roots and accelerate healthy hair growth.

However, there is no evidence that shows a direct impact of sage on hair growth.

4. May Lower Cholesterol Levels

High LDL (bad) cholesterol and low HDL (good) cholesterol levels can lead to severe metabolic and cardiovascular disorders. Including herbs like sage in food and medicine may balance the plasma lipid profiles. Although the tea does not have an effect on glucose regulation, it could be used as a beneficial treatment for individuals with diabetes (4).

Animal studies show that Chinese sage tea and its extracts can lower plasma cholesterol, LDL, and triglyceridesⁱ  A form of fat found in the blood that serves as the primary energy source and is necessary for optimal health. . The extracts could also increase HDL levels (1), (4).

Sage extract may improve the antioxidant activity in your body. It prevents the oxidationⁱ  A process where the fat molecules react with oxygen species and eventually breakdown and degrade. of accumulated lipids and protects you from diabetes, atherosclerosis(clogged Arteries), and other inflammatory diseases (1), (4).

5. May Aid Diabetes Treatment

This herb is used as a traditional remedy to fight diabetes in many countries. Many experimental studies report the glucose-lowering effect of sage in their subjects. Its extracts could do so without affecting the pancreatic insulin production (1).

Tea infusions of sage exert a metformin-like effect on your body. They are, in fact, as effective as the drug used in the treatment of type 2 diabetes (1).

Drinking about 300 ml of sage tea twice a day increases the antioxidant concentration in your body. The antioxidants, in turn, protect the liver and heart from chemical stress that is commonly caused by diabetes (1).

6. May Control Menopausal Symptoms

Menopause is characterized by major hormonal changes that affect your body. Its symptoms include hot flashes, sleeplessness, sweating at night, dizziness, headaches, and palpitations. These signs indicate the adaptation of your body to an imbalance of estrogen.

Sage has been traditionally used to treat menopausal symptoms. To prove its efficacy, a trial was conducted in 2011 on menopausal women with hot flashes. Those treated with 1 tablet/day of fresh sage leaves showed a 64% reduction in the intensity of the flashes (5).

The herb reduces excessive sweating and calms you down. Also, there are no reports of adverse effects of this herbal extract. However, further studies are needed to confirm the effectiveness of sage (and other medicinal plants) in the treatment of menopausal symptoms (6).

7. May Aid Weight Loss

Obesity is linked to diabetes, hypertensionⁱ  An abnormally high blood pressure level that increases the risk of heart disease, stroke, and other serious health problems. , heart and kidney diseases, and a number of chronic health conditions. Herbs like sage directly affect lipid digestion and fat accumulation (1).

The active components of this herb interfere with the activity of pancreatic enzymes. Carnosic acid and carnosol, which are diterpenes in sage extracts, are involved in this activity (1).

These molecules also stop the rise in serum triglyceride levels and slow down weight gain. There is enough experimental evidence proving the safety of sage when used as an anti-obesity agent (1).

Did You Know?

‘Salvia’, the scientific name of sage, is derived from the Latin word ‘Salveo’, which means salvation or to heal.

8. May Improve Oral Health

This Mediterranean herb has excellent antibacterial properties. Studies report that sage extracts could inhibit the growth of several food-spoiling bacteria, including the species like Bacillus subtilis and Enterobacter cloacae (1).

These antimicrobial effects were also seen on bacteria causing dental caries (Streptococcus mutans, Lactobacillus rhamnosus, etc.) The essential oils in sage leaves may be responsible for these effects (1).

When sage extracts were used in mouthwash and mouth rinse, they reduced the bacterial colony count from 3900 (pre-treatment) to 300 per plaque in treated patients (7).

Hence, this herb could effectively protect teeth from acute and chronic dental disorders, both in children and adults.

9. May Reduce Cancer Risk

Clinical studies found that common sage extracts could inhibit the proliferation (angiogenesis) of cancer cells. Ursolic acid found in this plant effectively suppressed the invasion, metastasis (spread), and colonization of melanomaⁱ  A type of skin cancer that begins in the pigment-controlling cells (melanocytes) of your skin. cells, according to evidence (1).

In another study on colorectal cancer, the active compounds of sage prevented the DNA damage of healthy cells. The antioxidants eliminate free radicals (like hydrogen peroxide) that cause such damage (1), (8).

The diterpenoids, sesquiterpenes, etc. isolated from the roots of the sage plant showed anticancer effects on liver and colon cancer cells. Similar results are reported on skin, prostate and intestinal cancer cells (1).

There are various types of sage, though not all have been identified yet for their medicinal properties.

What Are The Different Types Of Sage?

Many more wild and unclassified varieties of sage have been identified. Each of them is used differently in food, medicine, and rituals. Universally, sage is used to treat digestive and inflammatory issues. Its extracts and teas are effective against asthma, cough, blood circulation disturbances, etc. (1).

Benefits Of Burning Sage

Burning sage (also known as smudging) is an ancient spiritual ritual. It is believed to enhance spirituality and is also used in meditation practice. It may involve a different species of sage too (9). It has certain health benefits, such as enhanced alertness and antimicrobial properties. Some believe that burning sage is an important traditional remedy for treating mood disorders, depression, and anxiety. However, we need more concrete research to prove these effects.

In another study on cognitive science, the active compounds of sage were found to boost cognition (2). More research is needed to understand the mechanism behind these actions.

Studies demonstrated that smoke from medicinal herbs can clear up to 94 percent of airborne bacteria in space (10). Whether sage can achieve similar effects or not is yet to be studied. Some believe that when sage is burned, it releases negative ions, which may impart positive energy to people.

Meredith Ruben Daniels, in her blog, wrote about her first experience with sage, finding the smell surprisingly pleasant, like a warm campfire. As she walks through her house, wafting sage smoke into corners and closets, the energy shifts, creating a sense of calm. She saw a positive impact on her child’s behavior, reinforcing her belief in the power of sage for energy clearing and she wrote, “But I also noticed that my energy had shifted, my frustration had melted away, and I was in a headspace to be calm and sweet back (i).”

All of these benefits can be attributed to the herb’s powerful biochemical profile. The active molecules work as anti-inflammatory, antioxidant, antimicrobial, and pain-relieving agents. These properties effectively reduce the inflammation and pain associated with arthritis. In the following section, we will explore them in detail.

What Are The Active Components In Sage?

Sage leaves predominantly contain essential oils. About 28 components are identified in the oil. Their concentration varies in different locations and varieties (1).

However, the principal components are cineole, camphor, thujone, borneol, viridiflorol, thymol, phytol, geraniol, and carvacrol (1).

Linalool, humulene, limonene, pinene, terpinene, myrcene, camphene pimaradiene, salvianolic acid, rosmarinic acid, carnosolic acid, ursolic acid, and caffeic acid are the other polyphenolic compounds present in this herb (1), (11).

These phytochemicals act in synergy to give you the health benefits listed above. No wonder the Egyptians, Romans, and Greeks swore by sage!
