If you know Herbal Lore, make yourself some Speckled Wax -- if you don't then ask someone who does if they'd be able to make it for you. Bring the Ancusa Ceir to the Piet Inn and offer it to Saskia. She will put it on her mother's wounds and thank you for the salve.
My mother's awfully hurt by a fire that broke out.
Thank you. It's calmed my nerves, but I'm afraid it hasn't done her any good.
Offer Raw Honey
It's very sweet and so are you, but I'm afraid she looks no better than before.
Offer Speckled Wax
Just a moment. I will apply this to her burns.
Thank you so much. It's taking the heat away from her burn. Won't you have this?
My mother appreciates you helpin' her to heal.
