Since ancient times, cannabis has been at the center of the life of communities in a large part of the planet, as a reason for meeting, a fundamental element of cultural and religious ceremonies and also as an ingredient in many traditional medical therapies. A use, the medical one, which today is rediscovered by medicine. Many of you surely know this, but you may be surprised to know that there are over 120 active ingredients contained in cannabis flowers, almost all of which are still little studied and potentially useful for therapeutic purposes.
