I crave cardamon seeds.Ur craving must be due to an iron deficiency. Get checked.
I hope you are not actually eating it, but I haven't had that particular one, but I have craved other things like dryer lint, the smell of bleach, and snow. The other 2 posters are correct. Some postulate nutritional deficiencies, some postulate pregnancy hormones. I know when I addressed my anemia w iron supplements my bizarre cravings went down drastically.
I craved chalk & dirt, never ate either as hard as it was haha but as much as people told me it was a nutrient deficiency the doctor said it's just hormones.
It's called PICA, you need to talk to your doctor. I've heard it means you have a nutritional deficiency.
