plant iconThe Ministry of the Environment, Conservation and Parks (MECP) has heard concerns from the Aamjiwnaang community regarding the consumption and use of local medicinal plants. The Plants Study aims to assess chemicals in locally grown medicinal plants and compared with medicinal plants grown in neighboring communities. The Plant Study will include a review of chemicals in air that would most likely be taken up by plants.

The ministry has worked to compile and review existing information from relevant studies conducted in the Sarnia area. These were used to inform the Plants Study design, in order to better address the concerns of the community.

The Plant Study will be led by an academic team from Ryerson University, in collaboration with Aamjiwnaang First Nation. The ministry had been working with the Aamjiwnaang environment and health departments, Ryerson University and Health Canada to develop the Plant Study. Feedback and input on the Plants Study will be collected during community engagement meetings.

Sampling of Plants

The same species of plants will be collected from the Aamjiwnaang community, and from neighboring communities. The plants will be compared with one another to assess the levels of particulate pollutants found in the different locations.

Selection of Medicinal Plants

In late summer of 2020, a scouting survey was conducted to identify samples growing in Aamjiwnaang First Nation and a potential comparative community. The traditional medicinal plants species included in the final assessment will be determined and informed by the Aamjiwnaang community, and participating communities.

Sampling of both plants and soil will begin in the upcoming field season (Spring/Summer 2021).

Updates on the progress of the Plants Study will be shared during community meetings. Click here to view meeting materials.
