Be careful with long-term use if arnica, it is a toxic herbs and long-term use may allow the toxicity to accumulate. There are other herbs you can switch too like camomile, catnip, thyme, oregano, parsley, cayenne pepper, safflower…all are very cheap.
Getting an empty cleaned out glass jar with an air tight seal (jelly jar or something). Fill with 1 - 2 teaspoons of each herbs (some like cayenne pepper, you might want to start with 1/2 a tsp., it can warm up too much). Then pour vodka over herbs.
Soak in cheap vodka (keep vodka level at least 1” above the dried herbs) for at least 2 weeks. I personally let them soak for a month up to 3 months. Shake the contents periodically throughout the day (but once is good). Then strain through a coffee grinder inside a funnel (squeeze the vodka out of the soggy herbs in the coffee filter).
You now have bruise liniment!
Store in an air tight jar in a cool, dark place. Keep it out of sunlight as much as possible.
