The major benefit is that I no longer have intense bowel movements.
I used to get a strong bowel movement just before going out and coming home, or I would get a stomach ache before arriving at work in the morning, and I had to be very braced when going out.
I can’t tell you how many times I thought I might not make it.
I think it was worth taking “Indigo naturalis” just because I don’t have to worry about this anymore.
