Ivory and tusks, rhino horn, pangolin scales, tiger penis, tiger pelts, tiger paws, turtle shells, shark fins, the list goes on and on and on... a trip to a generic street market in China and you can find endangered animal species parts being sold openly for shockingly cheap.
How about banning any and all animal products involved in the quackery "medicine" trade or ludicrous edible "delicacy" which are the driving force behind the problem to begin with?
