This fruit's main strength (as shown by Jade) is that the user can ask any question to a person and can only be replied with the truth. The main advantage of that is that no one can resist telling the user (In this case, Jade) a truthful answer, making her skilled as an detective or interrogator and making her brilliant at gathering information. One flaw of this fruit is that as a side-effect anyone who speaks to the user can only say the truth. This could be quite rude or mean or nice and sweet towards the user.
