Allergy symptoms caused by a decaying Christmas tree inside a house or apartment.

Allergists have long suspected that live Christmas trees are the culprits behind some folks' runny, itchy noses during the holidays —and now one doctor believes he has proof. ...

Santilli placed a live Christmas tree inside an intern's apartment and took air samples for two weeks. (Santilli keeps his Christmas tree on a porch until Christmas Eve.)

For the first three days, the mold counts inside the apartment hovered around 800 spores per cubic meter of air, compared with a normal range of 500 to 700 spores per cubic meter. But by day 14, the mold count had skyrocketed to 5,000 spores per cubic meter. ...

Although the medical community has long known about "Christmas tree allergy," there has been some debate over what causes the sneezing, runny noses and watery eyes — pollen or mold.
