These do get rid of ailments that pet food won't get rid of, regardless of what you equip (things like Bio, Burn, Choke, Attack Down, etc.). They don't remove Petrify, though.
Pet food with AF removes status effects but this stacks to 99 and just removes status effects, I much rather use 1 of these than pet food that stacks to 12 to do the same thing.
Correct me if I'm wrong, but didn't Reward cure status ailments? I just bought a stack of these last night and I will test them out tonight. Hopefully it does more than just cure status ailments!
relic body +2 cures all 3 aliments af body removes and all 3 regular relic body removes. these are nice tho cause removes stuff the body doesn't. there is also another item called pet poultice that gives regen. now i want to test something. i know if wearing bodies during reward they remove stuff. wonder if i had something body could remove and used a regen item if it would remove and give me regen
