Well, it's either one these things.

1. It's simply a Fullbring. Orihime's power is manifested through her hairpins, which she has a strong emotional attachment to because they were a gift from her deceased brother. This has all the makings of a Fullbring, in which their powers are manifested through important items. This would also explain why Ichigo felt Orihime's powers got stronger while in Hueco Mundo, as Sado noted that his own Fullbring got much stronger because of the reishi in Hueco Mundo which is a natural source of power for Hollows and those with Hollow powers, like Fullbringers.

2. It's a power granted by the Hogyoku. This was Aizen's theory, that Orihime's desire to make a difference caused her wish to be "heard" by the Hogyoku. Which in turn granted the abilities to Orihime. This would sort of explains the causality rejection ability she has, which is incredibly OP since it seems to be able to reject anything but complete death. This causes it to match the Hogyoku's own causality abilities, which fuel evolution with no clear initiator other than a desire.

3. Or, its very possible its both of these things. The Hogyoku nutured an already natural power within Orihime and improved it to match her wishes. So basically, Orihime was already a Fullbringer and the Hogyoku just made her Fullbringer powers stronger. I'm more inclinded to believe this last option, as it would explain why she has a such a powerful Fullbring compared to other Fullbringers. Her ability to reject all phenomenon does not return physical abilities to an unrealistic state, rather it keeps everything as it should be. For example you can't use her ability to restore damage from training because it would undo the effects of the training as well, because it doesn't heal it reverts the body back to a point where it was health.

To me #3 is the most likely. But that maybe because I'm partial to the theory that the Hogyoku does not "create" powers rather it nutures or pushes evolution further. Even the Hollowfication of Shinigami or the Arrancarisation of Hollows is just forcing an already natural evolution that can happen under certain circumstances. The advantage is just you can force it on the strongest Hollows, whereas natural Arrancarisation happens apparently at random.

If we take that into consideration, it means Orihime's abilities are a perfect opposite. Where the Hogyoku enforces phenomenon on a natural object, Orihime rejects phenomenon and reverts it back. So like she "healed" Grimmjow's arm back to normal, if she did it long enough, she could have reverted him back to an Adjuchas as well.

This also supports Orihime's theory that she could destroy the Hogyoku. As her abilities can reverse the very creation of the Hogyoku back reversing the phenomenon that created it.
