Report of Morinda citrifolia chronic toxicity not applicable to commercial noni juice.
West BJ.

The results of a specific chronic oral toxicity test of noni fruit are not applicable to commercial noni fruit juice.  This is because the material tested was not of the same composition as juice that is commercially available.  Further, the results did not agree with several previously reported toxicity tests and human trials of noni juice.
