Wounds caused by the Soul Hammer couldn't be healed easily. At the very least, only a master of Kaidō on Captain Unohana's level could heal them.
The injuries also had to be brought under control immediately.
Otherwise, Nara Dan's Spiritual Power would gradually disappear until it was completely gone.
That was why Retsu Unohana had rushed to treat Sajin Komamura as soon as he was injured. If she hadn't treated him in time, Komamura could easily have died within a short while.

It might not even be a power from this world!
Aizen began to
