Iberogast® is born

The combination of 9 natural herbs used in Iberogast® was researched and developed in the late 1950s, at a German company called Steigerwald. By the early 1960s, Iberogast® was born. They used the existing extensive medicinal plant knowledge to expand it further to find the right composition and the mixing ratio of the selected nine natural plants. Quality standards and controls were defined and set standards for future production. Initially, Iberogast® was manufactured by hand, right from extraction and blending to filling and packing. This was a painstaking process.

Expand production

Scientific research into Iberogast® continued from the outset. In the 1970s, the aim was to make Iberogast®'s manufacturing process more effective and to expand production so more people could benefit from the treatment. Work was also done to make more doctors aware of Iberogast®.

Dual-action effect is discovered

In 1986, one of Iberogast®'s key characteristics was discovered: its dual-action effect. This means that Iberogast® has a different effect on the gastrointestinal tract19. It relaxes over-active stomach muscles and stimulates stomach muscles that are moving too slowly or weakly to relieve multiple digestive symptoms. This discovery led to a variety of new research activities and important publications. From the mid 1980s, additional research was carried out and proved Iberogast®'s extraordinary safety and tolerance.

Multi-target effect is discovered

In the mid 1990s, Iberogast®'s individual modes of action were researched. This led to its multi-target effect being found. Each of the nine specially-selected herbal plant extracts in Iberogast® have their own active ingredients that target different causes for digestive issues. Combined in Iberogast®, they reinforce each other and work together “synergistically” to relieve a range of digestive symptoms at the same time2. The treatment's efficacy was further investigated too, based on new international guidelines that had recently been introduced. This was the start to make Iberogast® today the most researched herbal gastrointestinal medicine worldwide7.

Research continues

The new millennium brought fresh discoveries. In 2003, new research uncovered Iberogast®'s ability to have effects in different specific regions of the gastrointestinal tract: it can relax the fundus in the upper part of the stomach and stimulate the antrum in the lower part19. The wider scientific community were immediately interested in this groundbreaking discovery. Further studies followed; in 2006 the effect of Iberogast® against Inflammation14 and motility disorders in the intestine confirmed11. The following year a positive effect on irritable bowel syndrome16 and inflammatory bowel disease identified14.
