As with Spanish moss and ball moss, lichens are often blamed for the decline and death of shrubs and trees. And, as with Spanish moss and ball moss, although lichens are frequently seen growing on the bark of plants, they do not cause harm.

Comment in Gastrointest Endosc. 1996 May;43(5):524-8. BACKGROUND: Oral sodium phosphate (NaP) is increasingly used as a colonic cleansing agent for colonoscopy. It has been shown to be efficacious, well-tolerated, and safe. Mucosal abnormalities associated with NaP have recently been described. We carried out this controlled study to assess whether bowel cleansing preparations commonly used in colonoscopy are associated with colonic mucosal changes that may mimic inflammatory bowel disease (IBD).
