This octogenarian devoted forty years of her life to making herbal medicines for wounded Earth Kingdomtroops at an abandoned medical institution. For a time, she was the only person living in and taking care of the institute, as all her students left the area to support the war effort. Her only companion was Miyuki, her beloved cat.
Aang learned that the herbalist lived at the top of a nearby mountain, and traveled there to find a cure for Sokka and Katara after they fell ill. After a brief yet frustrating meeting with him, the old woman told Aang that his friends must suck on the frozen bodies of hibernating frogs to be cured, which could be found in many of the region's riverbeds.
She resembled a Filipino hero named Melchora Aquino, otherwise known as "Tandang Sora". Some say that she became a teacher too, but because of the Philippine Revolution, she spent the last days of her life taking care of the wounded Katipuneros.
