The Homeopathic company Boiron makes a product called Apis Mellifica. It's a homeopathy product which is therapeutically active micro-doses of all sort of different properties including flowers, minerals, and biological substances thats actually the cause of the reaction your looking to correct. Cool stuff huh? They are safe and effective for adults, children, and even pets. No interaction with any other medications and no risk of overdosing. Apis Mellifica is used for swelling insect bites and other allergies. I've had great success with it.
In conjunction with the homeopathic product I used Sovereign silver gel. It's a homeopathic silver first aid topical gel that helps reduce redness and pain, good for all types of skin issues, bug bites and stings, plus so much more.

These two products worked very well. I recommend them to my clients all the time. I also really like the Charcoal poultice idea.
