They can worsen the allergies
Chamomile tea can worsen any existing allergy. In the past, allergic properties were attributed to the anthecotulid, but chamomile contains very small amount of this substance or not at all.
Today matrikiran is blamed for the allergies of chamomile. Sesquiterpene lactones that are found in the plant are the cause of allergies in many other plants which includes tansy, yarrow, and arnica.
An alpha-methylene group of the lactone ring should be a prerequisite for allergy. The flowers contain anthemic acid and tannin which can cause sickness.
