The Body Swapping Potion was a potion accidentally created by Paige Matthews while practicing her craft. To use the potion, one has to express the desire to be someone else or oneself again while it is boiling, and then add the last ingredient: powdered toadstool.
New to the Halliwell family, Paige was urged to learn magic quickly by her sisters. While brewing a potion with little care to the ingredients, she expressed her desire to be like Phoebe as she threw in powdered toadstool, causing both sisters to collapse and switch bodies.
Paige was eventually able to recreate the potion, switching back bodies with Phoebe. Piper later used the same spell to switch bodies with the Zen Master, who was kidnapped by his former student Yen Lo.
- Yen Lo referred to the switch as Soul Swapping.
