What is Hanahaki Disease?

The Hanahaki Disease is an illness born from one-sided love, where the patient throws up and coughs up flower petals when they suffer from one-sided love. The infection can be removed through surgery, but the feelings disappear along with the petals.

Hanahaki Disease Definition
The Hanahaki Disease is an illness born from unrequited love, where the patient’s throat will fill up with flower, they will then proceed to throw, and cough up the petals, (sometimes even the flowers).

One of the only ways for the disease to ‘disappear’ is if, the said person returns the feeling (it can’t be resolved with friendship, it has to be genuine feelings of love).

The infection can also be removed through surgery, though the feelings disappear along with the petals. If they choose nether options, or the feeling is not returned in time, then the patient’s lungs will fill up with flowers, and will eventually suffocate.

There is no specific flower for the disease, but it’ll either be the crushes favourite type of flower, or their favourite colour. We can only hope for the patients and pray that the crushes favourite flower isn’t a type of rose.

(The length of the disease varies with each person. But on an average, it will last up to 2 or 3 mouths, but sometime it’ll only last, a couple weeks).

For Example
The sight was sickening, the body lay limp on the carpet. stained petals, and flowers surrounding them, swirling in a pool of their own blood. I took a deep breath. Then turned to the rest of the group, keeping my head low. ‘Who said love couldn’t kill?’ I let out a low laugh.

“Darn you, Hanahaki Disease,” I curse under my breath. Tears threatening to fall.

Is the Hanahaki disease real? Facts in 2021
No. It is a fictional illness that occurs when the person who loves you doesn’t love you back. Often seen in characters in fan fiction, someone infected with Hanahaki disease will have a throat that fills up with flowers and they cough out the petals.

If the person’s love is returned then the disease is cured. The other “cure” is surgical removal, and along with the flowers, the feelings are removed as well. If left untreated it is said that the flowers will suffocate the lungs and the lovesick person will suffocate and die.

While certainly a dreadful faux demise, I would recommend googling Hanahaki and looking at the images as the illustrations are quite fascinating! It is actually just a fictional disease that is born from one-sided love.

The patient/victim is effected because their crush/attraction hasn’t returned their feelings. The Hanahaki Disease has the victim coughing up bloody flower petals because the disease takes place in the lungs. The disease can be cured but the feelings for that person disappear. The person can return the feelings and the disease would stop affecting the person.

For Example:
Hanahaki disease is not real. Just like we have the titular virus in Dan Brown’s novel, the Inferno, the Hanahaki disease is a work of fiction. We could call it lovesickness because it has to do with love and romance.

Okay, now you know quite well that the Hanahaki disease is not real and never would be. But I wrote a little more on this fictitious disease, which I think you would find interesting. Continue reading!
When one develops this fictitious disease called Hanahaki, a lot of things can happen. It is reported that people who suffer from this disease cough up flower petals.

Now the factor responsible for this sickness is unrequited love. It simply means loving someone and not getting loved in return.

Let me use John (a man) and Janny (a woman) to demonstrate the meaning of this disease. Assuming both of them (Peter and Jane) are close. John loves Janny to the point that he can take a bullet for her.

Unfortunately, the relationship is one-sided. John loves Janny, but Janny doesn’t love or feel the same way.

According to the Hanahaki disease, John may develop this disease due to unrequited love. In this case, his lungs will become filled with flowers and their roots, growing in his respiratory tract.

The only way John can become better is for Janny to return his love. The disease can also be removed via surgical operation. But if urgent action is not taken, the victim may die.

What are some fictional diseases like Hanahaki Disease?
Hanahaki isn’t the only fictional disease we have heard of and won’t be the last. The entertainment industry and fictional writers are always cooking up things to inspire their audience.

So we would see more of the Hanahaki-type of diseases as time progresses. I would also like to say that there are tons of other conditions that are similar to Hanahaki. They are fictional diseases that are not real.

But let me tell you something, almost all the fictitious diseases out there have a real-world equivalent. In other words, their creation was inspired by the real-life illness itself.

Mad Snail Disease
Let’s go over the different diseases:

Mad Snail Disease
Remember the widespread mad cow disease that hit the news now and then? The illness gave birth to the Mad Snail Disease. The Mad Snail disease isn’t real. The term was used in the popular cartoon program, SpongeBob.

This disease, as acted in the cartoon, developed following a bite from an infected snail. And once bitten, the victim develops messy pants, bloodshot eyes, loss of balance, and untrimmed toenails.

Mad Zombie Disease
Have you watched Zombieland, or Walking Dead? These are movies where humans were portrayed as brain-eating monsters. The Mad Zombie disease is also a work of fiction. There is nothing real about it.

According to those behind the idea of the Mad Zombie Disease, it is said that one bite transforms an individual. Now guess the real-world equivalent of this disease. Well, it’s the mad cow disease once again!

Ancient virus:
The ancient virus is a rare viral strain found in Queen ant genes. Discovered by ‘Alexia Ashford’ when she was studying ants. When combined with the progenitor virus it creates the powerful t-Veronica virus.

Sexually transmitted diseases exist. They can also move from one human to another. Now, what about the interaction between a human and a robot? Don’t you think a sexually transmitted disease when humans have intercourse with robots can occur?

Well, with all the numerous sex dolls coming from Japan and the rate at which people are patronizing them, a day would come when diseases like this can manifest.

But I hate to break it to you that Electrogonorrea isn’t real. And it never existed, which is good news for sexually active toasters out there.

Hanahaki Disease
Hanahaki Disease
Angel toxicosis:

causes the victim to eventually lose the ability to taste, sleep, cry, feel pain, and talk. It also increases the victim’s hearing, strength and sight abilities.

As well as eliminating the need to eat and sleep. In the early beginnings, it allows victims to gain crystal-like wings and fly until the disease is destroyed. The final stage of this disease causes the victim to give up his/her heart and memory.

Bendii syndrome
Another disease you may be hearing for the first time is “Bendii syndrome.” It’s also not a real disease like Hanahaki. But the concept looks scary, and yes, it has a real-world equivalent.

The Bendis syndrome, according to those behind the idea, is a generative neurological illness. It affects the elderly Vulcans – a group of fictional extraterrestrial humanoid species from outer space. The disease is believed to cause fever, weakness, fatigue, and emotional control.

Now the real-world equivalent of this disease is Alzheimer’s disease. And it’s a disorder that can cause the brain cell of humans to waste away. That is, degenerate and die. Alzheimer’s disease destroys one’s memories, including other forms of mental functions.


If you haven’t read any of Dan Brown’s novels, the Inferno should help change to your mind. But Dan isn’t new in the game. He has written several books, including The Da Vinci Code, Angels and Demons, and a host of others.

However, the Inferno is his latest mystery and detective fiction book. In the book, Dan wrote about the titular virus, which isn’t real, though.

The titular virus, according to the book, renders its victims infertile and is waterborne. But the villain in the book wanted it to destroy many people’s lives and decided to make the virus airborne.

One amazing thing you need to know about this titular virus is that it has a real-world equivalent, and it’s called the “Infamous Black Plague.”

Can You Catch HanaHaki Disease?
It looks different for different people. The trick is to try out different methods and do plenty of self-reflection. That’s how you can figure out what works for you.

For many people, pausing and taking a few deep breaths helps them manage their emotions. Others find it helps to listen to music, read a book, or exercise.

HanaHaki Disease
Stepping away from a difficult situation helps many people manage their emotions. If you’re feeling overwhelmed by emotion, try taking a break.

Cook and eat a meal. Go for a long walk. Do something you enjoy to get your mind off of it. When you come back, you’ll probably feel more able to handle the issue—and your reaction to it.

You may not really be at risk of catching HanaHaki Disease, but heartache itself can certainly feel like an illness. Have you ever found yourself nursing a broken heart?

We hope not! If it ever does happen, try out a few of the strategies we talked about. You may be surprised how much better you feel.

Find a friend or family member who can help you with these activities!
Everyone has their own way of regulating their emotions. Talk to an adult you know, like a family member, teacher, or doctor. Ask them how they regulate their emotions. Can they offer you strategies to try? What works best for them?

HanaHaki isn’t the only fictional disease out there. Read about a few others, like Dragon Pox or Hawaiian Cat Flu. Do you think either of these illnesses could have had real-world inspiration? Discuss with a friend or family member.

Think about the last time you felt a very strong emotion. Why were you feeling the emotion? How did you feel physically? What were you thinking about? How did you react to how you felt? Write a short personal narrative about what you felt and how you reacted to it.

Final words:
Hanahaki Disease is an illness born from one-sided love, where the patient throws up and coughs up flower petals when they suffer from one.

Hanahaki Disease (花吐き病 (Japanese); 하나하키병 (Korean); 花吐病 (Chinese)) is a fictional disease in which the victim coughs up flower petals when they suffer from one-sided love. It ends when the beloved returns their feelings (romantic love only; strong friendship is not enough), or when the victim dies. It can be cured through surgical removal, but when the infection is removed, the victim’s romantic feelings for their love also disappear.

The trope was popularized in East Asian fandoms (Korean, Japanese, Chinese) before it was used by Westerners. In fandom, it appears most frequently in relation to BL pairings.

The Hanahaki Disease trope is not used exclusively within fandom – many people have become intrigued by the concept and created non-fannish artwork, poetry, songs, music videos, and other creative works based around the concept. However, Hanahaki Disease is particularly popular within fandom due to its potential for angst, hurt/comfort, pining, and general romantic tension.

There is no set time for how long this disease lasts but it may last from 2 weeks to 3 months, in rare cases up to 18 months, until the victim dies unless the feelings are returned or the plants are surgically removed. There is also no set flower that blossoms in the lungs but it may be the enamoured’s favourite flower or favourite colour.

HanaHaki Disease
Hanahaki can be cured through surgical removal of the plants’ roots, but this excision also has the effect of removing the patient’s capacity for romantic love. It may also erase the patient’s feelings for and memories of the enamoured. It can also be cured by the reciprocation of the victim’s feelings.

These feelings cannot be feelings of friendship but must be feelings of genuine love. The victim may also develop Hanahaki Disease if they believe the love to be one-sided but once the enamoured returns the feelings, they will be cured.
