Polinesian Noni Research and Studies PDF Print E-mail
Written by Marzena Kolano   



  Noni's characteristics were recognised 6000 years ago and European civilisation discovered them in the early 18th century.

  One can also find some information on Noni in the Sanskrit, where it is mentioned that the plant was known in the Ancient times. At first it grew in South East Asia and it was used 6000 years ago in India. It was brought to Polynesian islands by people migrating from South East Asia and Indonesia.



  Captain James Cook devoted substantial space of his journals to Noni in the 1760's. Later, during World War II, a book describing survival techniques in the tropics published by the American military widely covered the advantages and uses of this tropical plant.

  There are a number of publications on Noni in the 1950's.


  In 1950, O.A. Bushnell published an article on the antibacterial properties of Noni fruit in “Pacific Science”. Bushnell and his associates found that Noni fruit extract provided antibiotic assistance against various strains of Salmonella and Shigella. Moreover, Dr. Oscar Levand, a University of Hawaii researcher, discovered that fresh noni fruit juice helped fight Pseudomonas aeruginosa, Proteus morganii, Staphylococcus aureus, Bacillus subtilis and Escherichia coli. He also stated that asperubzide – an active substance found in noni – may be an active antibacterial ingredient. Oscar Levand also wrote a thesis on Noni in which he proved the effectiveness of noni in neutralising many dangerous pathogenic factors. In his cautious hypotheses, he stated that 'the medical value of noni fruit has been proven in vitro by Bushnell and his associates, who examined 101 Hawaiian plants searching for their antibacterial activity.'

  Dr.'s Tabrah and Eveleth, in a report to the Hawaii Medical Journal, entitled “Evaluation of the Effectiveness of Ancient Hawaiian Medicine”, stated that the "Hawaiian Kahunas were highly specialized experts with considerable skill in physical diagnosis and pharmacology". Hawaii Medical Journal also presents Noni's effectiveness in traditional Hawaiian medicine.

  Dr. K.K. Agarwal examined Morinda Citrifolia's extract and its pharmaceutical properties. It has been discovered that noni fruit juice was effectual against three bacterial strains: Staphybcoccus aureus, Escherichia coli and Pseudomonas aeruginosa.

  Moreover, the antibacterial properties were also effective against five different intestinal pathogenic strains: Salmonella typhosa, Salmonella montevideo, Salmonella schottmuelleri, Shigelia paradysenteriae BH and Shigella paradysenteriae III.

  It should be mentioned at this point that Polinesian Noni is twice as effective in attacking pathogens. It is a great opportunity for sick people to promote the treatment of serious bacterial infections, the so called Sepsis, with raw noni fruit juice (preferably lyophylised, pasteurized is less favourable).


  Some research has shown that noni has an influence on various bacteria directly, whereas other additional research suggests that noni stimulates different immune system processes, which suppress the pathogenic activity even more.


Who discovered the powerful substances in Noni?


  Dr. Ralph Heinicke. Heinicke is a 1936 graduate of Cornell with a Ph.D. in Biochemistry. From 1950 to 1986, he worked for the Dole Pineapple Company as a researcher and was a lecturer at Hawaii Islands University. At the time, he was working to find some medicinal application for bromelain, an enzyme in pineapple. He was fascinated by the research over the enzyme miracle. In 1972 he discovered an enzyme occuring in pineapple – bromelain. As he began to work and publish, he discovered an ingredient in bromelain that he thought was responsible for the medicinal properties. He managed to isolate a substance and found the alkaloid, which was at the time wholly unknown to the biochemistry industry.

  During his further research in 1981, he named and patented this ingredient in 1983 as xeronin. In 1983, after discovering proxeronin, proxeronase and serotonin as elements crucial for synthesis and production of xeronin, he concentrated on finding a natural and rich source of them. Dr. Neil Solomon continued his work into the nineties.

  Dr. Heinicke disclosed that it was Noni fruit juice that contained large quantities of xeronin's precursor – 'proxeronin'. Further research revealed a vital role of the newly-discovered compound – xeronin. The research results over morinda citrifolia have exceeded Dr. Heinicke's expectations, as it appeared that Noni contained 800 times more proxeronin than pineapple!

  As an incredible plant, morinda citrifolia has been properly studied only since the beginning of the 1990's. As of today, almost 100 important elements have been found, starting from magnesium, calcium, phosphorus, copper and iron, to enormous quantities of Vitamin C, Provitamin A, group B vitamins, and a whole bunch of exceptional proteins and enzymes. In 1990 scientists from Metz University in France proved that Noni plays an important role in lowering high blood pressure. They also stated a strong painkilling feature of Noni juice (70% effective). It eases almost all sorts of pain which, as scientists claim, is the result of strong analgetics: serotonin and proxeronin.

  In 1992 Dr. Isabelle Abbott (an expert on botany), while drawing up some conclusions on her research, stated patients with diabetes, high blood pressure, and cancer to be the biggest beneficiaries of Noni's use.


  From 1992 to 1995 reports proving Noni's positive effect on cancer treatment were published at every annual congress of the American Association for Cancer Research. Dr. Anne Hirazumi Kim (Pharmacology), during her in-depth studies of morinda citrifolia, found that Noni's application neutralizes the effects of two substances impeding the action of lymphocytes T (the immune system cells) and macrophages. In her research she thoroughly described 66 various elements contained in Noni fruit and named them Noni – PPT.

  In 1993, a group of Japanese scientists from the Biomedical Science Institute and the Keio-gijuku University in Tokyo carried out a study of 5000 vegetable substances of morinda citrifolia, focusing on their positive effect on cancer cells. These scientists, including Dr. Umezawa, Dr. Tomonori, Dr. Hiramatsu and others, proved that damnacanthal was a very effective means of blocking some types of cancer cells.

  Dr. Steven Hall claimed also that not only did Noni bring positive effects but also reinforced the effectiveness of other therapies. According to him, the most unbelievable yet obvious was the fact that Noni helped so many patients for whom the traditional medicine seemed useless.

  Dr. Neil Solomon, a psychologist, physician, and journalist has been researching morinda citrifolia since 1997. In his research he studied over 50 reports of American doctors he cooperated with, and information of over 10 thousand of their patients. Dr. Solomon believes Noni to be effective in the treatment of diabetes: 'It was applied by the Polinesians in diabetes treatment hundreds of years ago' - he says. The use of Noni causes the level of sugar in the blood to stabilise.
