Merthiolate-Iodine-Formaldehyde (MIF) is a solution used in biomedical laboratories for concentration of stool samples prior to microscopic investigation for parasites. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non-concentrated samples the likelihood of finding equivalents of actually present ...
Compare that to stool transplants for Cassaday’s condition, ulcerative colitis, which Grinspan says leads to an improvement in about 25% of people, with 10% improving after taking a placebo.
