I infuse my oil which is either canola or olive oil with dried rosemary, horsetail, nettle, hot pepper, cinnamon, and a little bit of garlic powder. I let it sit for a few weeks as I don't have a double boiler or glass jar. I then strain it and add a heaping teaspoon of sulfur to 8 oz.
What do you strain it with? Do you use cinnamon power or bark?
