Allergies

Allergic reaction to Argentine giant cactus

01/22/2008

Question:

I was poked when working around an Argentine Giant cactus yesterday morning... This morning around 5am I awoke with a hot feeling (thinking it was a hot flash) then a burning sensation like a sunburn. When I arose and looked in the mirror, I was red in the face, shoulders arms, and eventually some of the trunk, and my legs. I applied a cold face cloth to my face, and arms, etc... and then took one benadryl...and took a shower. It seems to have subsided, so believe the benadryl helped. I did not realize that a reaction could take 24 hours +/- to take place. Is this a common reaction? Thank you.

Answer:

Many reactions to plants or their products may occur hours or even a few days after the initial contact.
