Please Try Loquat Heat Treatment As An Easy Home Treatment

Why I Recommend Loquat Heat Treatment

Loquat leaf heat treatment is even easy at home.

Loquat Leaf Heat Treatment, which has been handed down from ancient times, can now be easily made at your home.

Moist mugworm and loquat leaf extract is heated for moxibustion so you can enjoy a softer moist heat.

Since it does not emit an unpleasant odor or smoke, it can be used anywhere.

This is the superior heat treatment device for those who have chronic physical pain, for relieving fatigue and relaxing the mind and body.

In particular, it is widely recommended for the following people and perfectly demonstrates its effectiveness.

  • People with diseases that requires time to treat, such as cancer
  • People with chronic illness
  • People with an unknown diagnosis
  • People injured in sports or accidents and need treatment
  • People experiencing stiffness or are feeling heavy
  • People experiencing a lot of stress

My interview with Mrs. Nagatomo, the leading practitioner of Loquat Heat Treatment

During the summer of 2019 in August(with the sound of a cicadas singing in the background), I visited Mrs. Nagatomo’s clinic in Miyazaki Prefecture and asked her to talk about the connection between Loquat heat treatment and health.

If you would like to see the second part of the interview (the story of Mrs. Nagatomo and loquat heat treatment, cancer prevention, people who are more likely to recover from cancer and how they feel when they have cancer), please contact me and I will send you the video.

(Unfortunately, at this point the interviews are only available in Japanese.  We will be working to translate them in the future)

Mrs. Nagatomo Profile

Born in the Yamanashi Prefecture. In 1979, with her husband, she traveled to Sierra Leone in West Africa as a Missionary. In 1981, during her time as a Missionary, she became ill and needed to travel to New York where she was diagnosed with cancer. She was treated at Memorial Sloan Kettering Cancer Center. Later that year she began treatment at the same hospital where she would later gave birth to her twins at in April of 1984. By 1985 , she appeared on a TV Asahi Documentary called “The War on Cancer Part III: Surviving Terminal Cancer” and a NHK Educational Special in 1993 called “Why Do Humans Heal?”. Later, she opened the Loquat Hyperthermia Instruction Center. Currently, She is a member of the Miyazaki Cancer Countermeasures Council and a member of the Miyazaki Prefecture Board of Education’s Education Promotion Council. She is also the Chairman of the NPO Cancer Free Family.

Mrs. Nagatomo not only survived a diagnosis of only 6 months to live with terminal ciliary cancer but was also the first person to give birth to twins after beating the cancer. Since then, for the past 35+ years, she has devoted herself to the prevention of cancer, cancer education, ect. while also performing holistic based treatments focusing on loquat therapy.

How Is Loquat Heat Treatment Good For Your Health

1. Loquat leaves have long been regarded as good for health and have been popular as a simple home remedy

Loquat leaf hyperthermia therapy is a combination of loquat leaf therapy and heat treatment therapy, and the synergistic effect of both enhances the natural healing power (life force) of human beings and cures diseases.

At the beginning of the Showa era, Dr. Tetsuo Fukushima of Sapporo Railway Hospital said:

  • Loquat leaf therapy responds quickly
  • It is reliable
  • And is successful against diseases

He mentioned that the loquat leaf treatment has immediate effect, reliability, and can deal with various symptoms.

2. The history of loquat leaf therapy

1. Buddhist Shaka medicine from three thousand years ago

In one of the Indian Buddhist scriptures, the Nirvana Sutra (Mahāyāna Mahāparinirvāṇa Sūtra), the loquat tree was called the “King medicine tree”, the leaves were called “carefree fans” and the tree was said to have medical properties.  It was said that the King medicine tree, its branches, leaves, stems, and roots all had medical properties and that if someone who was sick breathed in the fragrance, held it in their hand or consumed it that it would cure their illness.

In addition, there is a description of the effect of loquat leaves in “Honzo-komoku” (1956, by Li Ji Jin) published in the Ming Dynasty of China (1366-1644).

2. Introduced from China with Buddhism during the Nara period

According to the literature of the Zen Culture Institute, loquat leaf therapy was introduced by Ganjin (founder of the Toshodaiji Temple) from China to Japan.  More specifically, the Emperor’s (Emperor Shomu) wife Empress Komyo founded the first “seyakuin (施薬院)” (hospital) in year 730, where loquat leaf therapy was performed.

Generally, Buddhist monks planted loquat trees on the grounds of the temples to use in loquat leaf treatments to the temples followers and villagers to help cure illnesses.  However, there were generally superstitions such as “If you plant a loquat tree in the garden, sick people will always gather,” or “Do not plant a loquat tree in the garden because it is unlucky.”

3. Why is loquat heat treatment good for you?

Amygdalin (vitamin B17)

Loquat is a member of the Rosaceae family in the same group with apricots, peaches, apples, pears, sakura, etc.  The components of loquat leaves include glucose, sucrose, fructose, maltose, starch, dextrin, tartaric acid, citric acid, malic acid, amygdalin, tannins and saponins.

In 1950, a biochemist in San Francisco named Dr. Ernest Krebs extracted and crystallized amygdalin from apricot seeds (apricot kernels), named it “Laetrile”, and used it to treat cancer.  This treatment was called “vitamin B17 therapy” or “Laetrile Therapy”.  

Dr. Krebs pointed out that lack of amygdalin due to uneven diet leads to abnormal metabolic activity, which leads to decreased immunity and antibacterial activity and causes not only cancer but also lifestyle-related diseases such as heart disease and diabetes.

High sources of amygdalin (B17) include apricot seeds, loquat seeds, loquat leaves, plum seeds, almonds, alfalfa, prunes, bamboo shoots, brown rice, soybeans, red beans, buckwheat and sesame seeds.  It is widely known that the people of the long-lived Kingdom of Hunza valued the seeds of apricots. Loquat leaf contains 20ppm of amygdalin.

4. Pharmacological action of loquat leaf

Processes where amygdalin is successful

When amygdalin enters the body, it is hydrolyzed by a special enzyme called beta-glucosidase, which is contained in large amounts around cancer cells, and hydrocyanic acid and benzaldehyde are released.  Cancer cells are destroyed by the synergistic toxicity of these two substances, but normal cells have a protective enzyme called rhodanese, which transforms both substances into harmless substances and is not affected.  Seen under a microscope, cancer cells die like insecticide-treated flies.

In addition, benzaldehyde formed by the decomposition of amygdalin is oxidized to benzoic acid, which is effective for antirheumatic, sterilization and analgesia (painkiller).  Among them, the analgesic effect is tremendous, and it is effective for relieving the pain of terminal cancer, neuralgia and sprain pain.

In 1927, Dr. Tetsuo Fukushima of Sapporo Railway Hospital published a paper entitled “Cyclic Acid Therapy Through the Skin”.

Dr. Fukushima wrote that many patients with intractable diseases were cured by treatment applied by Taikei Kono (principal priest of the Konchiin in Shizuoka, Japan), and the scientific mechanism by which “amygdalin contained in loquat leaves decomposed to produce a trace amount of hydrocyanic acid. It enters the body by absorption through the skin. Although hydrocyanic acid is a deadly poisonous substance, the production of a very small amount may have an enormous medicinal effect on the contrary.”

This paper, which focuses on the medicinal effects of amygdalin contained in loquat leaves, is thought to have helped establish the theory that “The Effect of Loquat Leaves = The Amygdalin Effect”.

After that (1950s), the extract of amygdalin “Laetril” was used for cancer treatment in the United States, and the theory of “The Effect of Loquat Leaves = The Amygdalin Effect” became more and more widely accepted.

For this reason, most books on loquat leaf therapy explain that the effects of loquat leaves are due to the medicinal properties of amygdalin.

Research at Osaka University

Around 1937, Dr. Hiroyuki Yasuda of Osaka University demonstrated the blood purification effect of loquat leaf extract in animal experiments.

Dr. Yasuda used a domesticated rabbit weighing around 600g, put 75g of raw loquat leaves in a metal cylinder, heated it and sprayed it on the abdomen from about 9cm away.

As a result, the blood of domestic rabbits was purified to weak alkaline in just 5 minutes. After a further 30 days, the bone tissue became firmer, the internal organs became healthy, and it gained weight.

Additionally, there is a case where a patient with penile cancer who was treated only with loquat leaf therapy under Professor Yoshio of Osaka University School of Medicine.  After treating the spine, abdomen, and local area three times a day for one hour, the cancer cells were completely destroyed in 49 weeks, and healthy tissue was restored.

Four effects of loquat leaf

In summary the effects of loquat leaf are

  • Anti-cancer
  • Analgesic (Pain relief)
  • Bactericidal
  • Blood purification

Is amygdalin a poison?

In recent years, the question of the efficacy of amygdalin against cancer has come to the forefront.  Questions such as “The medical effects of amygdalin have been denied, so isn’t loquat leaf therapy ineffective?” and “Amygdalin is a cyanide compound. Is loquat therapy dangerous?” have been raised.

This is in reverse order, and it is a well-known fact that the treatment of loquat leaves has been widely known for a long time, and amygdalin is only one of the hypotheses that explain its effect. However, the effect of loquat therapy is not denied.

In addition, the idea that “amygdalin is a poison” has come to be seen frequently, but amygdalin itself is different from water-soluble inorganic compounds generally called cyanide( such as potassium cyanide and sodium cyanide) and used by itself does not show any toxicity.

An enzyme called beta-glucosidase is required to decompose amygdalin to release its parts, and this enzyme is not abundant in humans. It is not something that will cause immediate poisoning unless taken in large quantities at one time.

There is no need to worry about if it is dangerous if you continue to take it for a long time and, unlike arsenic and hydrocyanic acid, does not accumulate in the body and cause chronic poisoning.

Latest research results

In 2002, Professor Yutaka Nishioka of the Kochi Medical University group revealed that the extract from loquat seeds has a strong ability to improve liver function.

The effects discovered through animal experiments are unlike any experienced with pharmaceuticals, and in examining the mechanisms from various angles, it has become clear that loquat seed extract has a strong effect of suppressing active oxygen.

Professor Nishioka is continued his research at Kochi University School of Medicine.  In 2008, it was proven that loquat seed extract is useful for improving allergic symptoms.

According to Professor Nishioka’s research, loquat seeds contain many amino acids and many other compounds that are beneficial to the human body.  Also the “antioxidant effect” in particular is superior amongst  its various effects.

In recent years, it has become clear that a substance called active oxygen, which is excessively generated in the body, is greatly involved in the onset and progression of many lifestyle-related diseases and intractable diseases.  Active oxygen itself is indispensable for the living body, but if it increases too much, it causes various disorders.

Therefore, it is said that preventing active oxygen from becoming excessive will prevent the onset and progression of the disease.

Loquat seed contains many active ingredients, and by complementing each other, it exhibits ideal properties as an antioxidant.  Therefore, it works by suppressing active oxygen and shows a strong antioxidant effect.

In this way, the effects of loquat seeds as a whole have been confirmed by recent scientific research, and the mechanism has become clear from a new perspective.

Personal Greeting

My name is Kaname Mamada.  I am a mother of 2 living in Hawaii.  As a master certified instructor I am working to help introduce loquat heat treatment.

I was born in Miyazaki, Japan but moved to Hawaii in 2017 with my 2 children (6 year old daughter and 3 year old son).  I also study natural remedies.

Loquat Heat Treatment and Me

My first encounter with Loquat Heat Treatment can be traced back when I was looking for something I could do to help a loved one recover from the cancer.

At that time (2013), I desperately searched for ways I could help with all my heart . I read many related books. I collected information on the Internet. I listened to the stories of people who survived cancer. I did everything I could to learn.

I learned that there are various types of self-care that can be done by ourselves, as well as treatments at the hospital.

We had a lot of encounters and learned a lot.  We did our best to do what we could.  Thanks to all of that work, my loved one began to recover.  Amongst all of our studies, loquat heat treatment was the most effective with the power of loquat and heats ability to penetrate.

It was so easy to continue using loquat heat treatment making it so we were able relax and feel calm more than anything else. There were times when it was tough, but loquat heat treatment always felt close to us and helped us heal.

My loved one lost physical strength when they were diagnosed with cancer, but they were able to get better using their own physical strength.

Now that shadow has disappeared.

I am happy that we didn’t give up even though everything around us was going pitch black.

I made this site in hopes of helping others out and teaching people about loquat heat treatment and making our experience hopeful for those who are suffering now.

Loquat heat treatment is easy enough that anyone can feel using it at home. I would like teach everyone about loquats excellent potential and healing effects.
