Yes I do, my mom's side of the family is native canadian (Cree & Anishnabe aka Ojibway) and I've grown up with various herbal medicines etc. We are careful not to mix certian herbal remedies with convential medicines as you could end up with adverse side effects etc.
For instance, someone taking blood thinner meds, shouldn't take garlic capsules every day as garlic also thins the blood. This happened to my mom, she had a stroke and was put on aspirin to thin the blood...then she started taking garlic everyday and didn't tell her doctor because she felt it was none of his business lol

In the end, her blood became waaaaaay too thin, her nose started to bleed for 5 hours straight etc, had to get rushed into emergency and the dr's burned the vessel inside her nose to stop the bleeding. That's when they found out she was taking garlic everyday in addition to the aspirin. So she gave up the garlic...if she does take it, she will take it for 5 days straight and then go off of it for a month or two, then back on. She also takes cinnamon and honey each day (she'll add it to her coffee/tea or on toast) and swears it helps her arthritis, cold prevention etc.
Just be careful about mixing herbal meds with convential meds. My grandmother always said never to mix the two because they don't compliment each other - one is artificial one is natural etc. To each their own. Just do your research first.
Oh yeah, be careful about wildcrafting (harvesting from the wild, as many plants look similar to each other), if you can take a herbalism class or get some good books with full size colour pics of the various plants that would be good.
We make our own tinctures, salves, massage oils, teas, herbal bandages etc. The Elder's say that for every sickness, Mother Earth provides a cure for it...but not everyone knows how/where to look.
