What are the best arguments against Christian Science?

[Anomalocaris]

Christian Scientists believe that diseases are not caused by a physical abnormality, but by a mental error. In other words, that all diseases are psychosomatic. So they can be corrected by prayer alone. What do you think are the best arguments against that belief?
I found two arguments that sound good to me:
1) The poison argument. "Suppose somebody drinks a glass of water that contains a poison, but nobody knows that it is poisonous. If Christian Science is right, then that poison could not kill that person. If medical science is right, then it can kill that person. And it is obvious which is true."
2) The jellyfish argument. Jellyfish are animals without a brain, and therefore without a mind. If all diseases are psychosomatic, they could not get diseases such as cancer. But they do get them.
Do you know some more?

Amazing a robot evaluates and select response options based on reading these options writing out in English and projected onto inputs of its optical sensors, like there was some literate gremlin operating via a VR headset.
