For a pimple that has become infected, try using an Earl Grey teabag as a poultice.
Chickweed (Stellaria media), applied as a poultice (crushed or chopped herbs applied directly to the skin) or added to bathwater, may also help relieve itching.
Skin problems such as boils, burns, or ulcers may benefit from a slippery elm poultice or tinctures when used several times per day.
Like most herbal remedies, St. John's wort may be brewed into tea, but it can also be prepared into a topical poultice.
At the same time, if the throat has begun to show signs of being involved, a hot poultice or wet pack is applied to the neck.
