The simplest definititon of Hemp is Cannabis sativa plants having a low or negligible percentage of THC. Laws change in various juristdictions, and some hemp is broad leafed like indica plants as well. Be assured if it is true hemp you will not feel the pyschoactive feelings from THC from ingesting it. The best primer on Hemp and its interesting history is the classic book “The Emperor Wears No Clothes” by Jack Herer. He was an inspiration to me and we met in person at the Cannabis Cup in Amsterdam (The Conspiracy Cup) in 2003.
