About the Study

Generally healthy? Researchers from the University of Adelaide are inviting healthy adults to join this study. 

Herbal preparations have been used for centuries for the treatment of gut symptoms. This study explores how this herbal preparation may relieve gastrointestinal discomfort in some people. To test this preparation, researchers need healthy individuals. 

Globally, about 5-20% of adults are affected by upper stomach problems. For those who suffer from stomach problems, this herbal preparation may be able to provide relief, resulting in greater enjoyment and productivity in everyday life.
