For CBD oil/ointment to have truly potent effects it's got to be full spectrum rather than an industrial hemp plant aka the shit sold in health food stores. If you're in a legal state and don't have access to flower/trim to make your own, Papa & Barkley is based in Humboldt County, CA and hands down makes the most effective salve. Releaf Balm 3:1 is legit and you can get it shipped anywhere. The THC based, Releaf Balm 1:3 is more effective however.
If you've got ganja byproduct to spare, even a zip will do, it's not hard to make your own salves with an instant pot- just know your crib will reek.
Ingredients: Jar of Coconut oil, beeswax, arnica, your choice of essential oils, flower. there are many recipes available that will guide you through making salve.
