To neutralize one's powers
Through spells or potions
- Piper: "Someone, I won't say who, has the insane notion of binding our child's powers."
- Leo: "Why is it insane? Grams bound your powers when you were a child."
- Piper: "Yes, and we spent twenty odd years ignorant about our destiny. I look back on those normal days and I feel like I was a complete and total fraud."

Power Binding is a term for neutralizing a being's powers. This method can be performed by means of spells or a binding potion. Unlike power stripping, it can be undone by a reversal spell, a potion or the death of the caster.
- "What? I unbound your powers without having broken the pact? Why would I do that? I mean unless I died which of course would automatically... unbind your powers. I guess I'm not going to make it to the next millennium, huh?"
- —Penny Halliwell discovers that the sisters' powers were returned automatically, meaning she died.[src]
Penny Halliwell bound her granddaughters' powers right after Phoebe was born, in order to protect them from evil. In 1998, she died of cardiac arrest, but her granddaughters' powers were not unlocked until six months later due to Phoebe moving to New York soon after she died and not returning until then.
Piper and Phoebe made the potion to bind the powers of Paige's past life, who was a powerful witch of the medieval times. They first wanted to vanquish her, but they wouldn't want to take the risk to lose Paige, since it was her Past Life and thus bound her powers instead.
Prue Halliwell voluntarily bound her own powers to bring The Power of Three under control, which had had become disrupted due to her reunion with her sisters. Her plan backfired when she gained all of her sisters' powers as well as her own due to Rennek switching magic over to mortals.
