Skin Allergy to Grass

Dear Dr. Kagen,

My name is Katelyn. I am 9 years old and I am doing a science project at school about why you itch after laying down in the grass. Could you give me information about this? Do you know a web site that would be helpful. You can send information to me at my dad's e-mail address.

Thank you.


Dear Katelyn,

Thanks for asking about skin contact allergy to grass allergens.

It is true that most patients who are allergic to grass are unable to sit in the grass without experiencing intense itching of the skin. The grass proteins which cause this allergic reaction can also be found in foods that grow like grass. These include tomato, celery, carrot, lettuce and potato skins.

I hope this brief information is useful to you. Be sure to read the section All About Allergy on our website. []

Good luck.

Steve Kagen, M.D.
