1. Improves Glucose Levels in Type 2 Diabetes

Cloves have demonstrated significant potential in improving glucose levels in individuals with type 2 diabetes. Clove extracts can mimic insulin’s effects, significantly reducing blood glucose levels in animal models. For instance, clove extract has been found to increase glucose consumption in muscle cells by activating AMP-activated protein kinase (AMPK) and sirtuin 1 (SIRT1) pathways, which enhance muscle glycolysis and mitochondrial function. Additionally, clove essential oil has been shown to suppress glucose spikes in type 2 diabetic mice, highlighting its potential as a functional food component for diabetes management. Clove supplementation can improve glucose, cholesterol, and triglyceride levels in people with type 2 diabetes, suggesting its efficacy as an antihyperglycemic agent.

What Research Says?

• Many studies show that clove can lower blood sugar in animals and people. For example, giving diabetic rats clove bud powder (CBP) made their blood sugar go down more than in rats that did not get the powder. Also, clove extract lowered blood sugar in diabetic mice by turning on a specific receptor called PPAR-γ.
• Clove can help lower blood sugar in several ways. It makes muscle cells use more glucose by turning on certain pathways, like AMPK and SIRT1. These pathways make muscles break down sugar better and work well. Also, clove stops liver cells from making enzymes that create sugar, acting like insulin and cutting down on sugar the liver makes.
• In a study of 36 people with type 2 diabetes, taking clove capsules (1-3 grams/day) for a month led to big drops in blood sugar, triglycerides, total cholesterol, and bad LDL cholesterol. This shows that cloves could help control blood sugar and improve cholesterol levels in those with diabetes.
• Clove has antioxidant and liver-protecting benefits, which help with diabetes-related issues. It lowered stress and liver enzymes in diabetic rats, showing it might stop liver damage. Also, clove treatment boosted antioxidant enzymes and the immune system in young rabbits, showing its good effects on health.

2. Reduces Cholesterol and Triglycerides

Clove extracts, particularly those rich in polyphenols and eugenol, can effectively lower levels of low-density lipoprotein (LDL) cholesterol and triglycerides while enhancing high-density lipoprotein (HDL) cholesterol. This lipid-modulating effect is attributed to the antioxidant properties of clove compounds, which help mitigate oxidative stress and improve lipid metabolism. Clove supplementation can lead to a decrease in serum triglycerides and total cholesterol, contributing to better cardiovascular health. Clove ethanol extract significantly reduced body weight, serum triglycerides, and total cholesterol levels by downregulating adipogenic and lipogenic gene expression. Incorporating cloves into the diet may offer a natural and effective strategy for managing cholesterol and triglyceride levels.

What Research Says?

• Researchers studied rats with type 2 diabetes caused by a high-fat diet and a chemical called streptozotocin. They found that adding clove bud powder (CBP) to the rats’ food greatly lowered fat levels, like cholesterol and triglycerides. The CBP made these fats drop, except for the good cholesterol known as high-density lipoprotein. Rats that didn’t get CBP didn’t see this change.
• In a study with 36 people who have type 2 diabetes, they took capsules with 0 to 3 grams of cloves each day for a month. The results showed their blood sugar, triglycerides, total cholesterol, and LDL (bad) cholesterol went down a lot. The study found that taking 1 to 3 grams of cloves daily can help lower the risk factors linked to diabetes, like cholesterol and triglycerides.
• A study looked at how clove bud powder changes yolk contents and fat types in laying hens. Adding clove bud to the feed raised vitamin E in the yolk and lowered its cholesterol. This shows that clove bud powder might help improve fat profiles in animals.

3. Topical Anesthetic Option
