ok, so its impossible to test all combinations, i get it.
Doesnt change the amount of damage being caused by the endless combinations, and it doesnt justify them making it worse by creating new drugs each time a patent runs out.
The way it is at the moment, ppl get prescribed 1 drug for a problem. The drug fixes that problem but creates 3 more, which the doctor then prescribes 3 more medications for which each creates more problems and so on.
This is the reason for the sad state of 'health care' in developed countries, and is why nutritional and natural solutions must be found and used in the first place.
