Also known as morinda or Morinda citrifolia, comes from a small evergreen tree. The research on this juice and its alleged health effects is considered “very preliminary” or “questionable,” and has yet to be supported by large-scale studies. Its primary benefit for skin, like that of most plants, is as a source of antioxidants. However, there are dozens and dozens of antioxidants with significant research on their benefits for skin, whereas very little exists for morinda. Like most antioxidant plants, noni (morindsa) also has skin-soothing properties.
