Narrative:

Approximately 25 mins into flight, a strong odor became evident throughout aircraft. I told flight attendant #4 that it smelled like horse manure/fertilizer/pesticide. Once it was verified that main cabin had just as strong of an odor, flight attendant #4 called captain to report. We were informed that we would be descending to under 10000 ft to release the cabin air and to put all service carts away and stowed. I called the captain to report that the odor was gone and he told me that we were now going back up to cruising altitude. While still on interphone, I reported that cabin was experiencing extreme heat and at that very moment the odor was back, but much stronger. Instant reaction to throat, nose, mouth. I instantly got a headache as well. Eyes were irritated and began to water. The masks dropped and passenger were instructed to use oxygen. The captain told me that we were diverting to nashville. No time to begin planned emergency checklist. Deplaned in normal fashion. All 3 flight attendants went to hospital, released after treatment and observation.
