We can use her in practically any Dendro composition since she can occupy the position of Healer and contribute Elemental Reactions of her element to support her team.
However, it would be best to use her to be the character that carries the Deepwood Memories set so that another Dendro character like Nahida or Alhaitham (to give some examples) can benefit from the Dendro Resistance reduction to enemies and can Equip a more suitable set of artifacts such as the Gilded Dreams set.
As with most Dendro characters, she makes good use of Elemental Mastery and in this case also Health if you want to boost her healing.
