Yuyuko's human body serves as the crux of the seal holding the Saigyouji Cherry Tree Dormant. She became the seal when she inadvertently killed herself with her power over bringing death to living beings.

Or, deliberately suicided by some accounts. All we know is that she died and she was used as a seal.
