How does homeopathy work? What can it treat? Scientists, doctors and homeopathic clinicians are looking for answers to these key questions, using the most rigorous methods available.

Welcome to HRI

HRI is a UK-based charity dedicated to promoting high quality research in homeopathy at an international level. The charity was founded by physicist, Dr Alexander Tournier, who previously worked as an independent researcher for Cancer Research UK, conducting interdisciplinary research at the boundaries between mathematics, physics and biology.

How does homeopathy work? What can homeopathy treat?
Scientists, doctors and homeopathic clinicians working with HRI are looking for answers to these key questions, using the most rigorous methods available.

What is homeopathy?

Homeopathy is a form of holistic medicine which has been used for over 200 years to treat both acute and chronic medical conditions. Homeopathy is growing in popularity; it is now used by 6 million people in the UK,1 100 million people in the European Union,2 and in India alone, 100 million people depend solely on homeopathy for their medical care.3

Why do we need more research?

A form of medicine this widely used needs to be researched, yet scientific research in homeopathy is a relatively new field. Consequently, there are many important, unanswered questions, such as, How effective is homeopathy compared with conventional medicine for specific medical conditions? What does homeopathy cost compared with existing treatments?  What effect do homeopathic medicines have ‘in vitro’? 

Researchers around the world have begun to investigate these kinds of questions and some exciting results have been published, but more research is essential if we are to find the definitive answers both patients and healthcare providers need.

Why do we need HRI?

Homeopathy is a complex subject that is only just starting to be explored. From what we know so far, the evidence suggests that homeopathy could provide solutions to many of the challenges facing us today – from overuse of antibiotics to spiralling healthcare budgets – but to know for sure, we need more hard data.

Despite its potential, research in homeopathy is not a government priority. For example, in the UK only 0.0085%4 of the total medical research budget is spent on the entire field of Complementary and Alternative Medicine, of which homeopathy is only one example. Until this changes, the work of HRI is essential.

“HRI has been a fantastic addition to the world-wide homeopathic community. In only 10 years they have become a leading authority on homeopathic research and worked tirelessly to present the evidence around the world.” – Faculty of Homeopathy

HRI relies entirely on donations. With your help, we can carry out the high quality research needed to determine the precise role homeopathy could, and should, play in the healthcare systems of the future.

As HRI is a registered UK charity, more information is also available on the Charity Commission website.
