This web site (in Dutch, regarding fraud) contains a section on Noni Juice which contains the following (translated) description: “Noni is a tropical fruit. There are only testimonial claims regarding this substance.

The testimonial claims regarding Noni are with regard to its benefits against MS, cancer, HIV, and cut off fingers. According to someone’s testimony a HIV patient had used it for 15 days and saw an increase of 90 CD4 cells. This can also occur if you do not use Noni. What has happened further to this HIV positive patient is committed from the story.

Another testimonial is completely unbelievable; a man with AIDS and a nasty opportunistic infection, was on the edge of death.

He started using Noni, nurtured himself back to health and has since a normal CD4-count and a normal viral load (sic). If this had really happened than the doctor in charge of this patient would have had the moral duty to report these findings for scientific publication. Because a substance is being used for centuries is very interesting but says nothing about the product. The fact that Noni is a natural substance and has been used for centuries in Asia and Polynesia does, therefore, not provide any information regarding the role it could play during treatment of HIV infection, if it even could have any role at all.” (original text by Kees Rumke)
