You don't say how old your daughter is, so this might not be appropriate, but the best non-pill 'traditional' remedy for a cold that I know of is a hot whiskey toddy. This is the traditional Irish recipe a friend taught me: Put two spoonfulls of honey and 1 small measure of good whiskey in a large glass or mug. Add 2 sticks of cinnamon. Cut a thick slice of fresh lemon, cut it in half, and stick 4-6 whole cloves into each half lemon slice. Add the lemon to the glass. Fill with not-quite boiling water (like for herbal tea). Stir well until all the honey dissolves. Best at bedtime.
