Can Wasabi Kill You? (How Much? Explained!)

Rate this post

Wasabi, sometimes known as green horseradish, has earned a reputation for being one of the spiciest foods in the world. Wasabi is a kind of horseradish.

But can wasabi kill you? No, wasabi can’t kill you. Wasabi is not poisonous, and it cannot kill you outright. However, there have been a few cases where people have had adverse reactions to wasabi that required medical attention. Mostly because of their allergy to wasabi.

Read on if you are curious in the amount of wasabi that would have to be consumed for it to be fatal, the symptoms of an allergy to wasabi, and other related topics.

Is there such a thing as too much wasabi?

No is the simple answer to that question. Wasabi is a potent condiment, yet it does not contain any toxins that might be harmful to your health in any manner. If you consume an excessive amount of wasabi, you may experience burning in your sinuses and lungs; nevertheless, unless you already have cardiac issues, it is unlikely that you will pass away as a result of consuming wasabi.

You shouldn’t be concerned about becoming sick from eating wasabi; but, if you like the feeling of having your sinuses flushed out all at once, feel free to pile as much as it as you want onto your plate. To err on the side of caution, however, and to avoid awkward situations from occurring, you should only use the condiment in little amounts.

In addition to this, there are two more variables that work against the wasabi’s ability to kill you:

  • 1) The wasabi in most restaurants isn’t real anyway; it’s horseradish with green food coloring!
  • 2) Real (authentic Japanese) wasabi is far from easy to come by outside of Japan and other parts of the world where they grow wild.

How much wasabi is enough to kill you?

The quantity of wasabi that would be required to kill you is far more than what can be contained in your stomach at one time. To begin, only a few hurried calculations. Pure wasabi has a density of 1.11 grams per milliliter, which is more than the capacity of the typical human stomach, which is 34 liters, to store food.

If you were to consume as much raw wasabi as you possibly could, it would amount to around 20 pounds or approximately 9 kilograms (9,000 grams).

The compound known as allyl isothiocyanate (AITC) is found in wasabi, and its presence is responsible for the plant’s pungent and unpleasant flavor.

To produce fatal AITC poisoning, a person would need to swallow more than 200 tubes of store-bought paste or 9 kilos of the fresh rhizome, and they would need to do it all at once since the body is able to eliminate this component rather fast after it has been taken.

Has anybody ever died as a result of wasabi?

The consumption of wasabi has not been linked to the death of anybody who has been investigated. The incident in Japan involving a guy who choked to death while eating sushi was the closest thing to a fatality that we could locate that was caused by wasabi.

Asphyxiation was determined to be the cause of death in the autopsy report; nevertheless, despite the fact that fragments of wasabi were discovered in his trachea, it is more probable that he passed away as a result of choking on a piece of sushi than from the wasabi itself.

The only other way that anybody might be wounded by the green paste is if they were allergic to the plant itself, which is uncommon but may happen. This is the only other way that anyone could get hurt by the green paste.

Wasabi does, in fact, have a number of positive effects on one’s health. Consuming wasabi not only helps destroy germs in your mouth and throat (including bacteria that may cause foul breath), but it also serves as an anti-inflammatory agent and may reduce the likelihood of blood clots forming. On the other hand, doing too much of it might result in some modest gastrointestinal difficulties, such as bloating or gas.

Is it possible to overdose on wasabi?

Sure, it is possible to consume too much wasabi, although doing so would be quite challenging. Wasabi is a highly potent herb. According to the National Institute of Health, the amount of allyl isothiocyanate (AITC) in wasabi that would be fatal to a human being is estimated to be somewhere in the neighborhood of one hundred milligrams for every kilogram of body weight. The active ingredient in wasabi is allyl isothiocyanate.

How much wasabi would have to be consumed before it could be considered lethal? To be poisoned by wasabi, a human being would have to swallow around 20 pounds of the green stuff in one sitting. This is an amount that is far in excess of what any person on Earth is capable of tolerating at one time. (And by the way, this is true for pretty much all varieties of hot sauce and meals that are spicy.)

The fact that wasabi does not cause addiction is a relief to anybody concerned about overdosing on it.

Is wasabi poisonous?

First, lets define poisoning. The term “poisonous” may refer to either anything that will end your life or food poisoning, which is an ailment of the digestive tract that is brought on by consuming food that has been contaminated with bacteria or viruses.

Is it safe to say that wasabi is dangerous in the sense that it may cause death? No. Even if you consume an excessive amount of it, the pungent and very spicy wasabi won’t do any long-term harm to your health (though you might get a stomach ache).

Wasabi poisoning causes what symptoms?

Burning sensations in the mouth, throat, and stomach are the most prominent signs and side effects of wasabi poisoning. Among the other symptoms are:

  • Dizziness
  • Difficulty breathing
  • Skin irritation (including a red rash)

The following are some of the most significant symptoms of wasabi poisoning:

  • Cardiac arrhythmia (irregular heartbeat)
  • Hypotension (low blood pressure)

Nonetheless, these symptoms are really severe. You shouldn’t be scared to enjoy your sushi with a generous helping of wasabi, so don’t be shy about doing so. Just dont overdo it.

Is it possible to be allergic to wasabi?

Yes, it is possible to have an allergic reaction to wasabi. Rash or swelling of the cheeks and tongue are two common symptoms of an allergic reaction. The degree of your intolerance will determine the intensity of your symptoms, but they will almost always involve a rash that itches and swelling of the face or lips.

Since serious allergies are nothing to joke around with, we strongly advise you to make an appointment with your primary care physician as soon as possible if you suspect that you may be allergic to wasabi.

In order to prevent unfavorable responses, you should absolutely abstain from consuming anything that includes the condiment. We are aware that this is something that is easier said than done, especially if you are in a restaurant and you do not know what is in the meal that you are ordering.

You shouldn’t try to cure a probable wasabi allergy on your own since doing so might make the symptoms more worse. See a medical professional as soon as you can if you suffer any of these symptoms after eating Japanese cuisine. They will be able to determine what precisely is causing the adverse response, which may require avoiding more foods than simply those that include wasabi.

How can you know if you have a wasabi allergy?

Talking to a medical professional is your best bet if you have concerns about an allergy, including one to wasabi. In spite of this, there are a few frequent indications of food allergies that you should keep an eye out for, including the following:

  • Abdominal pain, diarrhea, and/or vomiting
  • Anaphylaxis (breathing difficulties, swelling of the throat and lips)
  • Hives or rashes
  • Itchiness in your mouth or nose
  • Itchy eyes (possible sign of an allergic reaction to airborne irritants like pollen)

It is essential to make a distinction between a hypersensitivity response to food and a food intolerance. Having a food intolerance means that your body is unable to properly digest certain kinds of food. Although the symptoms may be similar, a food intolerance does not pose the same risk to your health as a full-blown allergy does.

In contrast to food allergies, which may be triggered by a single exposure to the allergen, those who have food intolerances often need many exposures to the offending food before they begin to exhibit symptoms.

Is wasabi capable of killing your taste buds?

Consuming wasabi will not, in and of itself, render your taste senses useless. In point of fact, the momentary numbness that you experience after taking a mouthful of wasabi is an indication that you are enjoying the raw horseradish in the correct manner.

What effects does eating wasabi have on the body? When you consume genuine wasabi, the sinuses in your nose are stimulated, which results in a numbing sensation in those areas. Moreover, the plant is capable of activating pain receptors in the nasal passages, which results in a somewhat uncomfortable sensation.

Since it may create both a cooling and a hot feeling at the same time, it is really one of a kind. There is no danger associated with feeling these sensations; nonetheless, they might be unpleasant for persons who have nasal passages that are very sensitive.

It has not been shown that wasabi has any long-term consequences on the degree to which we are able to sense food or other tastes.


To summarize, you may consume as much wasabi as you want, and the worst thing that will happen to you is minor irritation of the skin around your mouth. This is assuming that you do not have an allergy to wasabi. Wasabi is not poisonous, it will not cause your death, and it is even beneficial to your health since it contains antioxidants. But be sure you don’t get too carried away with it!

Quit using wasabi as a treatment at least two weeks before you are scheduled to have surgery.

What does wasabi kill?

Wasabi, commonly referred to as Japanese horseradish, is effective in eliminating microorganisms, particularly those that can be present in raw seafood. When you order sushi, you should be aware that some types of sushi, such as those featuring fried tempura, cream cheese, or mayonnaise, include additional calories and fat, which may rapidly mount up.

What happens if you eat a tube of wasabi?

Since it irritates the lining of your stomach, the isothiocyanate found in wasabi may make gastritis symptoms much worse. Wasabi is known to contain hepatotoxin, which is a substance that is harmful to the liver. But, when used in moderation, it poses no health risks. Acid reflux may be brought on by wasabi because of its pungent and spicy flavor characteristic.

Can wasabi hurt your brain?

Good mental health

Wasabi contains ITCs, which have the potential to have neuroprotective benefits. Researchers working with mice found that administering these supplements caused a greater activation of antioxidant mechanisms in the brain, which in turn reduced levels of inflammation ( 30 , 31 ).

Is it OK to swallow wasabi?

But, when used in moderation, it poses no health risks. Acid reflux may be brought on by wasabi because of its pungent and spicy flavor characteristic. If you suffer from stomach ulcers, gastritis, heartburn, or any other digestive disease, you should limit or avoid eating wasabi.

Why does wasabi hurt so good?

Does wasabi burn fat?

There is no proof that consuming wasabi or any other cruciferous vegetable affects weight reduction above and beyond the weight loss benefits that come from adding more fresh vegetables to your diet.

Combat the Diseases of the Respiratory System

Since it contains gaseous allyl isothiocyanate, consuming wasabi may help clear congestion in your respiratory system and disinfect it at the same time. According to a number of studies, isothiocyanate also has anti-inflammatory characteristics, making it useful for preventing infections and combating asthma.

Why does wasabi hit the brain?

It just so happens that foods like wasabi and mustard oil are loaded with isothyocyanates, which is one of the compounds that TRPA1 detects. Other molecules that TRPA1 identifies include a family of substances known as isothyocyanates. Hence, when wasabi comes into touch with a nerve cell that is equipped with a TRPA1 receptor, the nerve cell communicates with the brain by saying, “Ouch,” in essence.
