HCT is a new combination botanical drug substance that promises to be of value in treating various pathologies of the gastrointestinal tract, due to it's presumed "gastroprotective" and/or "gastrosynchronic" qualities. To test this hypothesis, a once daily oral dose of HCT will be self-administered to patients with IBS. The dose used is presumed to be exceptionally safe and is 37 times lower than the standard daily dose.
