Ontario Herbalists Association

Promoting safe & natural healing with plants since 1982

The OHA is gathered on the traditional territory of the Canadian First Nations peoples.

The OHA recognizes that for thousands of years, indigenous people have walked on the land we call Ontario; their relationship with the land is at the centre of their lives & spirituality. They walked gently on this land and offered assistance and shared knowledge to the first European travellers in what was at times a harsh climate.

We acknowledge and thank them for their stewardship of this land throughout the ages and seek a new relationship with them based on honour and respect.
We need to follow their example.

Indigenous Canada: Free Online Course

As a token of respect and gratitude for Indigenous peoples and the enormous influence they have on herbal medicine, we would like to encourage all of our members to consider enrolling in this free online course.

Expanding our knowledge and understanding of Indigenous issues, culture and history may help us all on the path towards reconciliation.
