I was asked about this in my Primary Exam! I have to admit that I had elected not to study the chemotherapeutics, (not a strategy that I would recommend ūüėČ) but fortunately I was able to drag something from the back of my brain….

There is one chemotherapeutic drug in particular which has very significant anaesthetic implications ( I was unaware of this 20 yrs ago!) and you should have some knowledge of it.

Several chemotherapeutic drugs, including vincristine, are derived from the above plant, the Madagascar Periwinkle…..
