Rinkoku kara Kita Yome ga Kawaisugite Doushiyou - Vol. 1 Ch. 5

[Dabaws]

So she was reincarnated and all this story is a shoujo game or manga where shes the villainess and was a doctor in her past life, classic

How the hell did they discover drinking wine with old nails was good for anemia?

This reminds me of how doctors and scientists were looking over old medical methods from yore, and one particularly gross medicine (it was something like poop mixed with particular herbs and dirt) was very effective against a nearly incurable disease.
The surprising wisdom of the past aside, how the hell did they figure out that the gross concoction would cure anything!? Did everyone who was sick with a disease all have to eat/drink such a thing and they took notes to see if it cured any of them? Did some sick person just happen to eat the poop mixture and notice it healed him? Crazy.

It's kind of like wondering who was the first mad man to eat milk or eggs - you saw it was an excretion of the animal, but decided to go for it anyway, and we salute you for that!

TBF, these last two, you can easily see animals drinking/eating them, and realizing it’s edible from that.
“Oh, babies drink milk… maybe it’s good?”
”Oh, these snakes eat bird eggs… maybe we could do that too?”
Like that’s probably also how people discovered you can eat cactus, seeing camels eating them.

If you want something that doesn’t make sense to think that anyone ate first one day, it’s the durian fruit… XD

It was hinted in the first chapter, but now it's pretty certain she's reincarnated. And from things she's said he may be one too in some form, just with no memories himself.
I'm not sure I've ever seen an isekai/reincarnation story from the sole perspective of those already existing in that world.
Oh, except for "The Executioner and Her Way of Life", though the tone is vastly different and not with the same premise of mystery about the reincarnation.

In the rainforest during durian season, everyone eats durian. Some even eats nothing but durian. That's right, humans or animals can actually survive more than a month eating nothing but durians.
Finding a fallen durian is even considered good luck. (Bloody hell if it actually fell on top of you)

ok so its isekai afterall with the main character being unware instead?
