Diary - I'm wondering what people would do

[Maybo]

This is an entry from my diary. Please check it and correct any mistakes.

I'm wondering what people would do when they had allergies in the ancient times. Did they have medicine to cope with it? If they had, was it effective fast? I suspect when people didn't know what allergy was in the ancient times, they might accuse others of poisoning food. Some people's allergy flared up because of just smelling nuts and died shortly, but they might not even know what had happened to them at that time.

Perhaps:

I wonder what people did in ancient times when they had a bad reaction to something. Did they think somebody had poisoned their food? Did they have remedies for that sort of thing?

You are right that people didn't know what allergies were in "ancient times". I'm sure there were remedies, but I'm also sure they were not effective with things like anaphylactic shock.

I would add "symptoms of" before "allergies" in the first sentence.

"Ancient times" does not need a definite article.

"Fast" in "effective fast" is redundant.

last sentence - ...they might not know what the cause was...
