Irritating plants

Manchineel

http://en.wikipedia.org/wiki/Manchineel

actually lots of them. No idea what the names of some are, but we have a large bush with blue lilac-like flowers that I can't touch. My husband has quite a few plants that give him a poison ivy-like rash...and he can get pretty sick pretty fast...and that is not even mentioning the mango, which he can neither touch nor eat. He never had issues in the sates with anything besides poison ivy/oak.

the sap from madagascar rubber, century plants and pencil bush.

then there is stinging nettle, christmas bush.....

check out where your kids were.

and go to a dermatologist, or try antihistamines if that is not possibile,

Mango's are very common as a possible allergen.There are many types of mango's, so you may not see the tree or shrub as a mango.Be very careful of pencil cactus, the sap can cause eye damage and blindness. The sap is easy to get on your cloths when cutting bush.Also look for sun exposure along with cologne on the skin this can cause a rash type blisters.

FYI Mangoes are closely related to Poison Ivy. 😮

Christmas bush gives many people a severe rash like PI only worse. I'll take a picture of it tomorrow and post it for the record. Also any milky sap is to be avoided, especially the cactuses.

Any other symptoms? Is it just dermatitis, or accompanying rash, fever, diarrhea, dilated pupils/etc? Manchineel, as rotorhead mentioned is only the culprit is cholinergic symptoms are present. If not, I would get your child tested for an allergy to grass... its very likely thats the culprit.

As others have said, Mango sap...many, many people are super alergic to it.

1/ i have been told mangos are related to sumac a plant very similar to poison ivy.i know of people who break out in a rash just by touching them. crazy as it sounds ,if i eat too much of them day after day i sometimes get an itching rash. 2/ i recieved a very irratating rash from the milky content inside the leaves of what i was told was called"dumb cane" .you see quite a bit of it around the islands. it has a thick stalk and very large white and green spotted leaves.3/ if your children are getting bitten outdoors, i would also be extremely cautious about misquitos.many parents prefer natural insect repellants such as lemongrass,but persoanally once you have had dengue i prefer to use all the "deet" i can get.

If they've been out in the water on a reef, they may also have gotten into fire coral. It stings at first and later causes a bumpy rash that can come and go like hives, complete with the itching effect. It usually heals up on its own in about a week, although if you scratch it it can stick around longer.

Here's Christmas bush or Comocladia dodonaea (also known less widely as poison ash)

The sap contains "urushiol" (LEARN MORE) which is the active ingredient in many irritant plants. Urushiol is also found in Poison Ivy, Poison Oak, Mangos (in the skin of the fruit), Cashews and Manchineel.

It gets it's name from the fact that it resembles holly and the leaves turn bright red at some times of the year.

Information on Urushiol-induced contact dermatitis HERE

Mild cases can be treated with ZANFEL and/or hydrocortisone cream.

Hope this helps!
