Do you take thousands of different medications weekly? It's pretty realistic to ask about medications you take and what interactions to avoid with that medicine.
Where did I say that? We're in a topic about medicine interacting with grapefruit. I suggest putting the warning on the medicine is a reasonable approach for this issue.
>Maybe you eat thousands of things and some interact with each other.
Whats your point here? Should every food list every possible interaction with every other existing food and medicine? Will I need to a read a 1400 page book before I can buy an orange?
