Asklepian Amoeba, also known as Bandage Slimes, are neutered oozes which still retain a keen sense for blood but lack any digestive capabilities. As a result they make for aggressive bandages, seeking out wounds to prevent bleeding. Generally this will stabilize a dying creature, and usually only requires a bonus action to quickly break their container and allow the amoeba to seek out the injury. Exceptional ones are treated with the alchemical essence of healing potions, which restores 2d4+2 hit points.
A greater goal would be to breed a type of ooze which naturally creates such curatives in place of the typical acid, which could result in a healing product of incredible potency.
