90% of the people who comment on this blog and tell us how they use “Indigo naturalis” show improvement in their ulcerative colitis symptoms.
What is the percentage of those who have tried “Indigo naturalis” but have not disclosed the results? Unless you do a full-scale clinical trial, I don’t know.
By the way, as far as I know from “Kusahami’s Ulcerative Colitis and Crohn’s Disease Update,” which is how I came to know about “Indigo naturalis,” Kusahami has been taking “Indigo naturalis” for about 1 year and 4 months and seems to have continued remission.
