I am convinced that the direct effect of
overwatering is suffocation of the root system, as the excess water "bridges"
the macroporosity between medium particles and cuts off the essential air
flow.
Adding hydrogen peroxide may be a
transient improvement, but considering the extremely short life span of a
hydrogen peroxide molecule in an organic environment, it's not going to solve
the problem, especially if the roots are so badly damaged that they cannot
recover. Not only that, there is a lot of "breathing" going on at the
roots, and hydrogen peroxide only VERY-temporarily addresses oxygen starvation,
not the stifled flow and buildup of gases expelled from the roots.
Repotting into a more "open" medium is the
better approach.
