Evidence-Based Benefits Of Cloves
Now that we have broken down the basics surrounding cloves, what does science say?
1. Antimicrobial Properties
An antimicrobial is an agent that kills microorganisms or stops their growth. Cloves have been shown to contain antimicrobial properties.
Studies carried out to assess the antiseptic potential of cloves revealed that clove oil had a greater antimicrobial effect, compared to a clove extract that included ethanol and a known preservative called sodium propionate.
Cloves have also been shown to aid with oral health due to its antimicrobial properties. According to a test-tube study, compounds that were extracted from cloves were found to stop the two types of bacteria that contribute to gum disease.
With a combination of regular brushing and maintaining proper oral hygiene, cloves can also benefit oral health.
2. Rich In Antioxidants
Cloves contain rich compounds that are beneficial for the human body. Antioxidants are one of them and they are predominately found in the oily interior of the cloves.
Some of the antioxidant compounds are Vitamins (A and C), Eugenol, minerals, flavonoids, and phenolic acid.
Vitamin C is responsible for protecting the body against oxidative stress and fight off free radicals.
Eugenol is 5 times more effective in combating free radicals than Vitamin E (another potent antioxidant.)
An antioxidant research study was conducted to compare 6 various spices and cloves were shown to have maximum antioxidant potential more than garlic, ginger, and mint.
3. Improve Liver Health
The liver has many functions, one being the main detoxification organ that uses several enzymes to process, filter, and remove the body’s toxins.
Because of the high functionality that the liver performs, it is subjected to high levels of stress that leads to the build-up of free radicals.
This often leads to either chronic or oxidative stress that causes metabolic imbalances in the body.
The compounds that are found in cloves, mainly Eugenol has been proven to be beneficial to the liver.
Studies have also shown that both clove oil and eugenol were found to improve liver function and reduce inflammation among rats that had liver disease.
Apart from being anti-inflammatory, Eugenol can also improve damaged tissue and reverse signs of liver cirrhosis.
4. Helps With Digestion
Phytonutrients are natural compounds that provide essential nutrients for the human body. Cloves contain phytonutrients that help stimulate the secretion of digestive enzymes that help with the reduction of stomach problems such as bloating, flatulence, gastric irritability, and dyspepsia.
It has also been proven that clove oil can treat stomach ulcers because the phytochemicals that are found in the clove oil increase the production of mucus in the stomach.
Gastric mucus acts as a protective barrier preventing the thin stomach lining from being exposed to strong digestive acids (bile and gastric)
In old traditions, people would apply clove oil to help relieve morning sickness and ease symptoms of indigestion.
5. Boosts Immune System
The human body needs to have a strong immune system. Cloves have the highest antioxidant potential in comparison to other superfoods.
Clove oil extracts contain antibacterial and antiviral properties that boost immunity that helps fight off bacterial and viral infections.
This is because clove oil contains polyphenols that increase white blood cell count, resulting in a stronger immune response against bacterial and viral infections.
Finding a way to implement cloves into your diet can benefit you tremendously. Ground cloves can be used in similar ways like cinnamon and ginger to flavor soups, meat, and even baked goods.
Cloves have been used for centuries and are considered safe, but too much of something is harmful to one’s health. This is because Cloves contain a high concentration of Eugenol that can cause liver damage when taken in high doses.
Clove oils are often diluted with other oils such as coconut to reduce the effects. And they are not recommended for children under the age of two.
