If you have an allergic reaction, it means your body cannot handle what you give to it. Say flowers (common) make you sneeze and itch, (like my sister) it is because there's something inside whatever makes you allergic is not good for your body, or your body is not used to it. Can I get a thank you and a rating?
*Hope it helps!!*
