The flower buds of the clove tree (Syzygium aromaticum) are commonly known as the spice called cloves. Not only do cloves add flavor to hot drinks, pot roasts, and cakes, but they also provide a range of health benefits. Cloves have been shown to have antibacterial properties, support liver health, regulate blood sugar, and provide a rich source of antioxidants. Let’s take a closer look at several health benefits of cloves below.
Improved Liver Health

Eugenol, a key compound in cloves, may help protect liver health by reducing oxidative stress and inflammation. In an animal study, researchers gave clove oil to rats with liver disease, resulting in reduced liver inflammation and improved function. However, high doses may be harmful to the liver, so more human studies are required to determine the optimal amount for safe consumption.

Packed with Antioxidants and Nutrients

Cloves contain significant amounts of antioxidants and essential nutrients. These antioxidants help combat oxidative stress, which is linked to diseases such as multiple sclerosis, dementia, depression, and Alzheimer’s. Cloves are also rich in eugenol, a potent antioxidant that may help protect cells from free radical damage. Additionally, cloves provide essential nutrients like fiber, vitamins, and minerals. For example, they contain 55% of the Daily Value of manganese, a mineral that plays a crucial role in bone formation and brain function.
Better Bone Health

In the United States alone, low bone mass affects around 43 million adults, increasing the risk of fractures and osteoporosis. Animal studies suggest that compounds in cloves may help preserve bone mass. One study found that eugenol-rich clove extract significantly improved bone strength and density. Additionally, the manganese in cloves supports bone health and formation. While most research on cloves and bone health has been conducted on animals, the findings suggest potential benefits for humans as well.
Improved Blood Circulation

Cloves contain compounds that may support heart health. Some research suggests that cloves can help regulate cholesterol levels and blood sugar, which are key factors in cardiovascular health. Drinking clove-infused tea may help transport nutrients and oxygen throughout the body, contributing to overall well-being. However, more studies are needed to confirm these effects in humans.
Stomach Ulcer Relief

Research indicates that compounds in cloves may help protect against peptic ulcers, which develop due to stomach infections, stress, or a reduction in the stomach lining. If left untreated, these ulcers can cause significant digestive discomfort. One animal study found that clove extract was as effective in treating stomach ulcers as conventional medications. More research is needed to determine its effectiveness in humans.

Lower Blood Sugar Levels

Cloves contain compounds that may help support blood sugar control. In one animal trial, clove extract helped diabetic mice maintain stable blood sugar levels. Another study found that nigericin, a compound in cloves, enhanced the uptake of sugar from the bloodstream into cells, increased insulin production, and improved the function of insulin-producing cells. While these findings are promising, additional human studies are required to confirm the effects of cloves on blood sugar regulation.
Making Your Own Clove Tea

Drinking clove tea is an easy way to enjoy its benefits. This aromatic beverage can be made using ingredients commonly found in grocery stores. Whole cloves can be crushed and added to boiling water or infused with tea leaves for a unique flavor. Clove tea may provide the health benefits listed above, as well as antimicrobial properties that can help fight bacteria and support respiratory health.
The Bottom Line on Cloves

Not only do cloves add a rich, aromatic flavor to your favorite dishes, but they also offer a variety of potential health benefits. From relieving stomach ulcers to supporting bone health, balancing blood sugar levels, promoting heart health, and improving liver function, cloves may be a valuable addition to a healthy diet. However, while animal studies suggest promising effects, more human research is needed to confirm these benefits.
