One Health Organisation

One Health Organisation (OHO) is an independent humanitarian agency for Holistic Primary Health Care (HPHC), which formed in 2005 to bridge the gap between the wellness sector and the community sector. Run entirely by volunteers, OHO was founded upon the principles of HPHC in a spirit of co-operation, goodwill and service in order to realise a common goal of health for all.

OHO is now the largest organisation of its kind in the world and has collaborated on over 100 projects in 12 countries to bring holistic and integrative healthcare to those most in need. This impact would not have been possible without the vision and support of Metagenics which has been our Major Sponsor since 2009. Together we continue to strive towards our shared goal of health for all.

However OHO cannot continue this vital work to support the poorest and most vulnerable communities without the support of Practitioners like you.

What it's all about
