Pot of Liberation

The Pot of Liberation (開水壺) is an ancient artifact of the Musk Dynasty which removes the seal of Jusenkyo victims placed by the Pail of Preservation.

Manga history
At some point into their history the Musk Dynasty acquired the Pot. However, unlike the Pail, the Dynasty lost the Pot for centuries as it was traded amongst several individuals during China's turbulent history, until finally finding it's way to Japan.

Due to being sealed into his female form by a monkey woman, Herb, along with Lime and Mint, travelled to Japan so that they could retrieve the Pot and allow Herb to change back into his male form. Eventually the group track the Pot to Horai Mountain where Herb broken the kettle-shaped boulder in which the Pot was sealed, with the resulting waterfall of water allowing Herb to finally return to his male form. The Pot was eventually lost in the ensuing between Ranma and Herb.
