I'm so excited, I am answering my first request:  What to do about poison ivy?  It certainly is an itch!!
Items to have on hand for combat:

1. Felsnapha Soap 
2. Rhus toxicodendron ( homeopathic 12x or 6c)
3. Aloe vera or cucumber slices

First;  wash area that came in contact really well with warm soapy water, (I have heard Felsnapha soap works best).  Make sure to remove clothes right away and put them in the washer alone, wash on hot with bleach.
Secondly;  take the homeopathic tablets, under tongue, in-between food, every hour for the first 3 hours then every 3-4x daily until symptoms subside.

Lastly;  several things work well on the blisters such as:  aloe vera (I use it right from the plant, cut a piece of the leaf and squeeze in on rash), or place cucumber slices on rash. Another helper is Jewelweed,  nature's antidote, it usually grows conveniently near posion ivy. Don't ya just love that! The leaves can be juiced and applied to the rash 2-3 x daily. You can identify this plant by the smooth soft leaves and the orange snap dragon type flowers that appear in mid summer.

Let us not forget Calundula, the almighty skin healing herb.  A paste of Calendula tincture, buttermilk and sea salt can be applied to help dry up the weeping blisters. If this is all to much to handle, the old stand by, Calamine lotion works well, at drying up the blisters as well.

I would like to mention the importance of covering up blisters that are actively weeping.  These are open wounds which can become infected.  I know of someone who was in Hospital for 10 days due to a strep infection from an active poison ivy rash.  Always cover open wounds, that's why they invented band aids after all!! :}
