Hanahaki Disease Overview

Hanahaki disease a fictional medical disease or condition. When a person suffers from one-sided love, they develop Hanahaki disease, which causes them to cough up flower petals. It comes to an end when the beloved returns their feelings (romantic love only; deep friendship is insufficient) or when the victim passes away.

It can be healed by surgical removal, but once the infection is gone, so do the victim’s romantic feelings about their relationship.

Before it was used by Westerners, the trope was popularized in East Asian fandoms (Korean, Japanese, and Chinese). It’s most often used in relation to BL pairings in fandom.

The Hanahaki Disease trope isn’t only used by fans; many people have been inspired by the idea and have developed non-fannish artwork, poetry, songs, music videos, and other artistic works based on it. Hanahaki Disease, on the other hand, is especially common among fans because of its potential for angst, hurt/comfort, pining, and general romantic tension.

terms Hana(meaning “flower”) and hakimasu(simply means “to throw up”).

The Japanese shoujo manga-Hanahaki Otome, or The Girl Who Spat Flowers, by Naoko Matsuda, which was published in 2009, popularized the Hanahaki Disease trope. Strong pain, flowers blooming in the heart and lungs, and then throwing them up are some of the signs of the disease.

However, among East Asian (particularly Japanese and Korean) fans and creators, the idea of flower regurgitation as a result of unrequited love predates the release of Hanahaki Otome. Its real roots are unclear at this time.

This trope comes in a number of ways and can be seen in both happy and sad tales. It usually takes months or even years to develop, starting with a few petals coughed up and gradually increasing in severity (and pain) until the victim is vomiting whole flowers, at which point the disease has progressed to its final stages.

When the girl of the victim’s love returns their affections, the love is no longer unrequited in the happy ending version. The illness is then cured by the patient. This may occur naturally when the object of affections discovers his (usually him) love or the disease may enable the object to reassure the victim that their love is mutual(two-sided). If the victim is unable to believe that his beloved reciprocates his feelings, he will perish.

Another common version is when the victim’s lungs become stuffed with flowers and roots grow in their lungs. They choke to death on their blood and petals. The angst that comes with the character death makes it famous. The angst that comes with the character death makes it famous.

Cure of the Hanahaki Disease

There are also works in which the roses, as well as the victim’s feelings of affection, are surgically extracted, leaving them unable to love the person they once loved. This can also erase the victim’s memory of their former lover, as well as their desire to love again. Frequently, the person who is infected may reject surgery, choosing to die rather than lose their feelings.

Many artists and writers use cherry blossoms as the flower of the petals that characters cough up, even though the flower is symbolic of something valuable to the characters. Flower symbolism is also common in western fandom, for example, to reflect the victim’s or their loved one’s affections or personalities.

Summary of Hanahaki Disease

Hanahaki Otome was serialized in Kiss Magazine, introducing the world to the fictitious Hanahaki disease. Hanahaki disease is a fictional illness that only affects people who have experienced unrequited love. Rose petals would be coughed up by the victim, symbolizing their affection. This condition can only be healed when the victim’s romantic feelings are reciprocated.

Surgical treatment is the only other method for treating the disease. This surgery removes the roots of all of the flowers that are forming in the victim’s lungs. However, the surgery not only extracts the flowers, but also the victim’s romantic feelings. This means that if a person is cured of a disease by surgery, they lose their affection for the person who caused it.

Why Love Sickness Occurs

It can occur in persons both in a relationship or love someone but cannot express. The person waits for his/her lover to show up, they become obsessed with love. They feel jealous even for small matters. Some signs of love sickness;

  • Invading thoughts more about a romantic interest.

Though some of these symptoms may appear to be innocuous, they can develop into something more serious. Self-doubt, insomnia, and intrusive thoughts are common symptoms of major depression. Furthermore, long-term exposure to anxiety and stress can increase the risk of heart disease and stroke.

Treatment of Love Sickness

Lovesickness can appear to be an incurable disease. Is there, however, a way to end the agony that goes beyond the healing balm of time?

The concept of a cure for a broken heart is almost as old as love itself. Ancient love cures included phlebotomy, exercise, bloodletting, abstaining from rich foods or wine, and drinking plenty of water. The majority of modern treatments are geared toward addressing mental health issues.

The victim of love sickness should be assured, gently treated, and have enough support from others. When a person is heartbroken, there is no other medicine than love. That love should be provided by friends and family.

Sporotrichosis- A real disease caused by a flower

Sporotrichosis is also known as rose gardener’s disease is a fungal infection caused by the Sporothrix fungus. This fungus can be found in soil and on plant matter such as sphagnum moss, flower beds, and grass all over the world. When people come into contact with fungal spores in the water, they develop sporotrichosis. The most common type of infection is a cutaneous (skin) infection. The fungus reaches the skin through a minor cut or scrapes, typically after someone comes into contact with infected plant matter. The hands and arms are the most frequently affected areas.


  • Cutaneous (skin) sporotrichosis
  • Pulmonary (lung) sporotrichosis
  • Disseminated sporotrichosis


The signs of sporotrichosis are determined by the location of the fungus in the body. If you have indications that you believe are linked to sporotrichosis, consult a doctor.

The skin or tissues under the skin are normally affected by sporotrichosis. A tiny, painless bump that appears 1 to 12 weeks after exposure to the fungus is typically the first symptom of cutaneous (skin) sporotrichosis. The bump may be red, pink, or purple, and it generally occurs on the finger, hand, or arm where the fungus has gotten into the skin through a crack. The bump can grow bigger over time, resembling an open sore or ulcer that takes a long time to heal. Additional bumps or sores can develop near the original one in the future.

Pulmonary sporotrichosis (lung sporotrichosis) is a rare condition. Cough, difficulty breathing, chest pain, and fever are some of the symptoms.

The symptoms of disseminated sporotrichosis vary depending on the portion of the body is infected. Infection of the joints, for example, can cause joint pain that is mistaken for rheumatoid arthritis. Central nervous system infections can cause trouble concentrating, headaches, and seizures.


The majority of sporotrichosis situations only affect the skin or the tissues under the skin. These infections are not life-threatening, but they must be treated for several months with antifungal medication prescribed by a doctor. Itraconazole, which is taken by mouth for 3 to 6 months, is the most common treatment for this form of sporotrichosis. Another treatment option for skin sporotrichosis is supersaturated potassium iodide (SSKI). If you’re pregnant, avoid using SSKI and azole medications like itraconazole.

If you have serious sporotrichosis that affects your lungs, bones, joints, or central nervous system, you’ll most likely be given intravenous antibiotics and antifungal medication. If you have sporotrichosis in your lungs, you can need surgery to remove the contaminated tissue.


Hanahaki disease is a fictional disease, still, the creator describes it in a way that people believe it as a real one. This is where the creator gets the achievement.

Victim of hanahaki disease vomit petals and flowers

In a better world, one persons’ love should not be rejected this way. Love is unconditional and holy. Those who receive this kind of love from someone, he/she is the luckiest man in the world.
