The Entourage Oil contains a broad spectrum of cannabinoids terpenes and other cannabis component which work together to produce what is know as the Entourage effect. The concept of the Entourage Effect was conceived by an Israeli scientist called Raphael Mechoulam - who is the man who first discovered CBD. From his detailed studying of the cannabis plant Mechoulam concluded that cannabinoids such as CBD have heightened impact when taken alongside other cannabis compounds. In other words a cannabis oil made from extracted cannabis - containing the hundreds of compounds naturally found within the cannabis plant - should be more effective than pure CBD taken on its own.
