You can overdo some things like that. A friend of mine was working where they made salsa. It had a lot of cilantro in it. I gorged myself pretty good on it and after that I don’t care for cilantro.
Apparently there are reasons why some like and some can’t stand cilantro. I’m not sure if they are really genetic, or biological, or just psychological; but differences exist in how people perceive cilantro. I like it, but it can certainly be overdone even for those inclined toward it - like anything.
