We both know, it was never explained how Hashirama died, it just seems like he would sacrifice himself to save his comrades. There is no-one from that time period other than Madara that could have defeated him. Madara said that Hashirama didn't need to weave signs to heal. That doesn't mean that Hashirama even needed a technique, he could have just naturally healed himself.

To use your own words, There isn't any evidence of that though. So no, it is not safe to say Hashirama even used a jutsu to heal, since his cells alone have regenerative abilities. Also, you can't say it uses rapid cell division, simply because we don't know the mechanism behind Hashirama's power. For all we know, Hashirama's cells could spontaneously repair themselves.

Be careful not to contradict your own logic. Note, this is not intended to be an insult, just some constructive criticism.
