Do you think this "short history of (western) medicine" is accurate? Please see details.

I recently came across this somewhat tongue-in-cheek “History of Medicine” while reading.

2000 BC—Here, eat this root.
1000 AD—That root is heathen. Here, say this prayer.
1850 AD—That prayer is superstition. Here, drink this potion.
1940 AD—That potion is snake oil. Here, swallow this pill.
1985 AD—That pill is ineffective. Here, take this antibiotic.
2000 AD—That antibiotic doesn’t work anymore. Here, eat this root.
2010 AD—That root is contaminated. Here, practice energy medicine.

What are your thoughts…?
