My son was three years old when he woke up from a nap covered in hives. I had no idea the cause; he had no unusual exposure to food or anything that I could think of. In trying to figure out what to do (I was worried it was going to get worse! ) I considered that one of his older brothers, whom he is a lot alike, has had trouble with allergies and asthma in the past. If that son took Nettle capsules and Quercetin daily, his problems stopped and eventuallly healed. No was could I get a three year old to swallow capsules. I made him some Nettle Tea, sweetened it (honey, stevia, whatever) and he drank it in a sippy cup. In twenty minutes, his hives were gone. The next day it happened again... He woke up from his nap with hives. Less this time. I gave him Nettle Tea again and they were gone very quickly. That was over a year ago and he hasn't had hives since. Nettle is amazing! I had trouble with chronic hives years ago and I wish I had known about Nettle back then.
