We are well aware of how tobacco is major cause of cancer, so when people look at fields of Nicotiana plants they will think they are looking at a plant which is the source of so much disease in the world.
But wait!
Here’s a new study showing that the very same Nicotiana plants produce a protein called NaD1 (snappy name, huh?). The plants produce this as part of their defence against fungi, but it now appears the very same NaD1 can bind with the cell membranes of cancer cells and puncture them, leading to their death.
As one of the reporters who wrote about this said –
I am beginning to feel kindly towards the genus Nicotiana (the tobacco plants), which seems to contain a molecule that bursts cancer cells. It just goes to show you that life is full of surprises
The plant which can cause cancer can also be a cancer cure? Well, well, well………..
Heroes Not Zombies 
Well, well as you say!
“This raises the prospect of the deepest kind of irony: tobacco grown to produce drugs used to treat cancers caused by tobacco.”
I wouldn’t call it irony just ignorance! Wonder if ‘they’ have heard of Hahnemann.
The Peter Paul and Mary song springs to mind -“When will they ever learn?”
