Foraging Plant information list

This is not a complete list, this is a list of the species I have directly witnessed in my travels here in Northwest Ontario. If you find something before I do, email me and let me know.

A common method is to soak the St. Johns Wort in a high alcohol Vodka for two to 4 weeks to make a tincture. Then simply take a few drops a day.


St. Johns Wort is easily recognizable by the tiny apparent perforations in the leaves. These are tiny holes where the leaf itself is transparent and when held up to light it appears to be riddled with holes.

The Flowers are bright yellow flowers with five petals with conspicuous black dots. When the flower buds or seed pods are crushed, a reddish/purple liquid is produced. The reddish/purple liquid is the good stuff.

Where to look

Along roadsides/disturbed areas, they enjoy sun  and a multitude of soil types. Driving bush roads where the roadsides are cut back regularly provide great habitat.
