The other ingredient I need for the poultice is feathers from the Shadowgale shrieklings that roam this forest. In their juvenile form, the shrieklings have insulative feathers which would be ideal to put over the moss. These feathers will prevent the antiseptic sap from drying out and will provide at least some protection against the elements.
Be warned, the shrieklings are normally docile but they have been incredibly hostile of late. Their large talons can easily disembowel you if you aren't careful.
