Health Benefits of Cloves
Health Benefits of Cloves
Cloves are the flower buds of the clove tree, an evergreen also known as Syzygium aromaticum.
Found in both whole and ground forms, this versatile spice can be used to season pot roasts, add flavor to hot beverages, and bring spicy warmth to cookies and cakes.
High in antioxidants
In addition to containing several important vitamins and minerals, cloves are rich in antioxidants.
Antioxidants are compounds that reduce oxidative stress, which can contribute to the development of chronic disease.
Cloves also contain a compound called eugenol, which has been shown to act as a natural antioxidant.
In fact, a test-tube study found that eugenol stopped oxidative damage caused by free radicals five times more effectively than vitamin E, another potent antioxidant.
Including cloves in your diet along with other antioxidant-rich foods can help improve your overall health.
May help protect against cancer
Some research suggests that the compounds found in cloves might help protect against cancer.
One test-tube study found that clove extract helped stop the growth of tumors and promoted cell death in cancer cells.
Another test-tube study observed similar results, showing that concentrated amounts of clove oil caused cell death in 80% of esophageal cancer cells.
The eugenol found in cloves has also been shown to have anticancer properties.
A test-tube study found that eugenol promoted cell death in cervical cancer cells.
However, keep in mind that these test-tube studies used very concentrated amounts of clove extract, clove oil, and eugenol.
Eugenol is toxic in high amounts and overdosing on clove oil may cause liver damage, especially in children. Further research is needed to determine how lower amounts may affect humans.
Can kill bacteria
Cloves have been shown to have antimicrobial properties, meaning they can help stop the growth of microorganisms like bacteria .
One test-tube study showed that clove essential oil killed three common types of bacteria, including E. coli, which is a strain of bacteria that can cause food poisoning.
What’s more, the antibacterial properties of cloves could even help promote oral health.
In one test-tube study, the compounds extracted from cloves were found to stop the growth of two types of bacteria that contribute to gum disease.
Another study in 40 people tested the effects of an herbal mouthwash consisting of tea tree oil, cloves, and basil.
After using the herbal mouthwash for 21 days, they showed improvements in gum health, as well as the amount of plaque and bacteria in the mouth.
In combination with regular brushing and proper oral hygiene, the antibacterial effects of cloves may benefit your oral health.
May promote bone health
Low bone mass is a condition that affects an estimated 43 million older adults in the United States alone
It can lead to the development of osteoporosis, which may increase the risk of breaks and fractures.
Some of the compounds in cloves have been shown to help preserve bone mass in animal studies.
For example, an animal study found that clove extract high in eugenol improved several markers of osteoporosis and increased bone density and strength.
Cloves are also rich in manganese, providing an impressive 30% of the DV in just 1 teaspoon (2 grams) of ground cloves.
Manganese is a mineral that’s involved in the formation of bone and incredibly important to bone health.
An animal study found that taking manganese supplements for 12 weeks increased bone mineral density and bone growth.
However, current research on the effects of cloves on bone mass is mostly limited to animal and test-tube studies. More research is needed to determine how it may affect bone formation in humans.
May reduce stomach ulcers
Some research indicates that the compounds found in cloves could help treat stomach ulcers.
Also known as peptic ulcers, stomach ulcers are painful sores that form in the lining of the stomach, duodenum, or esophagus.
They’re most commonly caused by reductions in the protective lining of the stomach, which are due to factors like stress, infection, and genetics
In one animal study, essential oil from cloves was shown to increase the production of gastric mucus
Gastric mucus functions as a barrier and helps prevent erosion of the stomach lining from digestive acids
Another animal study found that clove extract helped treat stomach ulcers and exhibited effects similar to those of several anti-ulcer medications Though the anti-ulcer effects of cloves and their compounds may be promising, further studies are needed on their effects in humans.
