Research & Development

MediHerb and Integria Healthcare have a strong commitment to excellence in natural healthcare research and make significant investments in research and development (R&D).

Over the years Integria Healthcare has supported more than 20 human clinical trials of our products, with the results published in peer-reviewed journals. Additionally, the company funds a range of other research, in particular phytochemistry and in vitro studies.

Led by Dr Hans Wohlmuth (PhD), Integria’s R&D team collaborates with researchers from around the world, including scientists from some of Australia’s leading universities and research organisations.

For over 25 years MediHerb has been a pioneer, dedicated to the research and development of premium quality professional products. We are extremely fortunate to have an outstanding team of people in Research and Development and Quality Control: over 14 scientists including two chemistry PhDs, a biochemistry PhD, two herbalists, nine chemists, and a dietician. Together the team has diverse industry experience in food and herbal products, university research, drug analysis in hospitals, pharmaceuticals, quality assurance, technical writing and clinical nutrition.


Based at the Integria Healthcare head office and laboratories, the Research and Development team closely collaborate with the University of Queensland, Griffith University, Southern Cross University and University of New England.


The research team is led by Professor Kerry Bone and Associate Professor Reg Lehmann and assisted by MediHerb’s technical writer, Michelle Morgan.

MediHerb Herbal Research Objectives

The research group is committed to the development of efficacious herbal therapies. This involves three major areas of focus, which are all interconnected:


  • Formulation of efficacious herbal solutions to meet patients’ needs
  • Validating the efficacy of herbal formulas by clinical trials and in vitro research
  • Researching the phytochemistry of medicinal plants


It is by combining phytochemical, biochemical, clinical and traditional herbal knowledge that MediHerb can continue to produce high quality products, which meet the changing needs of the market.


The MediHerb Research Laboratory is well equipped with gas chromatographs (GC), thin layer chromatography (TLC), ultra-violet-visible (UV-Vis) spectrophotometers, high performance thin layer chromatography (HPTLC) and high performance liquid chromatographs (HPLC). The HPLCs are equipped with photo diode array (PDA), evaporative light scattering detectors (ELSD) and sophisticated mass spectrometer (MS) detectors. Access to nuclear magnetic resonance (NMR) and infra-red (IR) spectrometers, polarimeters, gas chromatographs with mass spectrometer detection and HPLC with MS/MS capabilities is available at The University of Queensland campus.


The Research and Development team works closely with herbalists and naturopaths within the company and with a board of leading Australian and international herbalists on product development. This ensures that MediHerb has taken the best of science, traditional knowledge and current clinical knowledge to make the most therapeutic herbal solutions relevant to your clinical practice.


"MediHerb employs more scientists in Research and Development than any Australian practitioner company"



New Product Development Process

MediHerb has a rigorous new product development process, which ensures that the appropriate steps are undertaken when investigating the introduction of a new product. By reviewing all the relevant information available regarding the therapeutic outcome, we are seeking to develop a short list of key herbs and nutrients which are then subjected to closer analysis.
This involves detailed examination of the:


  • Clinical outcomes
  • Phytochemistry/Biological activity
  • Analytical methodology
  • Continuity of supply
  • Economic sustainability
  • Synergy of the final formula
  • Cost to the patient
  • Practicality of final dose formulation


Once the prototype formulation is agreed upon, MediHerb may undertake a controlled human trial to prove the efficacy and safety of the product. This may either be a full clinical trial or may be an open trial in conjunction with our experienced clinicians (feedback trial). Products with well-documented evidence of traditional use are often subjected to the feedback trial. For more novel formulations that do not have significant traditional use, a full clinical trial evaluation may be performed.
