Meng Po, also known as Lady Meng, is the goddess of forgetfulness and amnesia. She creates a tea known as Mi-Hun-T’ang or Five Flavoured Tea of Forgetfulness. The tea she makes is created from herbs from various ponds and streams.
Meng Po works in the realm of the dead where she gives her tea to souls ready to be reborn so they do not remember their previous life or time in the underworld. As soon as the Five Flavoured Tea of Forgetfulness is drunk all memories of the previous life is lost along with knowledge, creating a blank state.
