Poultices are similar to compresses, except that in poultices the whole herb is applied directly to the affected area instead of a liquid extract. There are several kinds of poultices for a wide range of problems. So I am not sure which precise poultice recipe you are looking for. I will list some common poultices and their applications, so you can select whichever one is useful to you.
Onion Poultice- For bronchial inflammation and ear aches.
Slice 3 large onions and saute them in distilled water until transparent. Fold one half on the onions into a diaper and apply directly on the patient's chest. Place a towel on the chest to hold in the heat. Once this pack cools off use the other half of onions in a similar way. Wipe the chest dry.For ear aches apply on the ear , but make smaller packs.
Plantain leaf poultice - For scrapes, cuts, stings and to remove foreign objects such as thorns or glass pieces.
Blend plantain leaves with water until a thick mucus like paste is formed. Apply this on a gauze pad and directly apply to the hurt area. You can apply a little olive oil to the area to prevent the pad from sticking.
Sage and Vinegar Poultice - For bruises and swelling
Bruise a few sage leaves and put them in a pan. Use enough vinegar to barely cover the leaves and put the pan on a slow flame. Let the vinegar simmer and not boil. The poultice is done once the leaves are soft. Place the leaves on a soft cloth while still hot and fold up the cloth. Apply to the bruised area as hot as the patient can tolerate. Cover in some towels and leave it for an hour.
There are many different poultices and unless you specify the problem it is hard to figure out which kind you may need.
