Wasabi, when finely grated, releases many chemicals, and some of them may have an anti-microbial effect of killing bacteria. Wasabi has shown a limited ability to kill bacteria on touch. Eating raw fish paired with wasabi may reduce the chances of infections caused by bacteria in fish. Eating it may help kill some bacteria in the mouth, throat and digestive tract.

Wasabi benefits – Anti-inflammatory

Wasabi, although known for causing mild inflammation of the nasal passages, may have an anti-inflammatory effect on the rest of the body. The chemicals found in wasabi have things in common with capsaicin found in hot peppers, which has been proven to have anti-inflammatory effects. Eating wasabi may help with inflammations, sores and pains in the body. Additionally, it may be helpful to blocking prostaglandin, which is the neurotransmitter primarily responsible for pain and inflammations. Taking wasabi during a fever may in some cases help lower it. It may also help with pain from sore muscles. It can also help with the healing process by lowering the inflammation effect, which can slow down the natural regenerative processes of the body.

Wasabi has also been used for liver detox programs, with some suggesting eating large amounts of it to help the liver clear toxins. Some of the chemicals contained by wasabi are not normally found in any other foods consumed, and these may have an even greater effect on liver health.

Wasabi and prevention of cancer

Since the liver is the main detoxifier of the body, promoting its functions may have an effect that reduces chances of getting cancer. Namely, some of the toxins metabolized and destroyed by the liver may have mutagenic potential, which means they may alter the structure of DNA and cause mutations that can result in cancer. Since some compounds found in wasabi may stimulate the liver to clear out such toxins, it may also have an anti-cancerogenic effect.

Antioxidants benefits of Wasabi

Wasabi contains many active chemicals which exhibit powerful antioxidant abilities. Antioxidants are chemicals which deactivate free radicals. Free radicals are electrically charged chemicals which are a natural byproduct of our metabolisms and well as effects of pollution and some lifestyle habits, such as drinking alcohol, smoking or eating junk-food. These free radicals can cause much harm in the body, as well as be factors which increase the chances of cancer. Wasabi may have natural antioxidant properties, which means it deactivates free radicals and helps preserve health.

It does this by stimulating the nasal passages and causing a very mild inflammation, which in turn causes mucus to be secreted which can then was out the allergens such in the nasal and sinus passages. It’s potential effects in inhibiting prostaglandin may also contribute to an effect on allergies, since allergies are a form of inflammatory reaction. It may help people with seasonal allergies as well as people with asthma.

Wasabi has been shown to have mild inhibitory effects on blood platelets, which means it has a chance of preventing blood clots from forming. This may be especially beneficial for people already suffering from heart disease or people who are at a high risk of stroke, since stroke and some forms of heart attack are caused by tiny clots forming in the blood.

Anti obesity properties of wasabi
