Motor oil chemical smell
Flavor Name: Cherry Seed Oil
I bought black seed oil this time and this stuff smells like motor oil or something leaking from a car.
I had to look this up cuz it’s so strong it gives me a headache. It says it’s been over processed or store improperly if it has a strong automotive smell to it.
Yuck. Im so mad. I haven’t been using it cuz the smell is so bad so I just had to look it up. It’s weird that it smells so chemical like. Not okay at all. I bought mine in October- it says it doesn’t expire until 2027. I’m so mad right now.
