For what it's worth, fiber-workers (knitters, spinners, weavers) in Australia massage emu oil into their hands as an anti-inflammatory. A friend was scheduled for hand surgery that got postponed during lockdown. I sent him a bottle of food-grade emu oil which he massaged twice daily for three weeks and the 'arthritic calcification' and pain disappeared. The hand surgeon had no explanation but the lump has not returned in the two years since. And surgery and post-surgical healing were avoided.
