Homoeopathy can be used to treat sick or injured birds in the same way it is used for humans. Remedies can be given by crushing pellets and adding them to the bird's water or directly into its mouth. Common remedies for birds include arnica for trauma, aconite for shock, ignatia for grief, symphytum for broken bones, rhus tox for stiffness, dulcamara for chill, arsenicum for changes in weather, and carbo veg and hypericum for wounds. A book on homoeopathic treatment for birds is recommended for bird owners.
