Chamomile

[4][5] The word chamomile is derived via French and Latin, from the Greek χαμαίμηλον, khamaimēlon, 'earth apple', from χαμαί, khamai, 'on the ground', and μῆλον, mēlon, 'apple'.

[14] The main compounds of interest in chamomile flowers are coumarins, flavonoids, and polyphenols,[8] including apigenin, quercetin, patuletin, luteolin, and daphnin.

[17] The use of chamomile has the potential to cause adverse interactions with numerous herbal products and prescription drugs and may worsen pollen allergies.

Despite the presence of coumarin, as chamomile's effect on the coagulation system has not yet been studied, it is unknown whether a clinically significant drug–herb interaction exists with anticoagulant drugs.

[4] Although oral consumption of chamomile is generally recognized as safe in the United States, there is insufficient clinical evidence about its potential for affecting nursing infants.

The following fungi are known to attack this plant: Albugo tragopogonis (white rust), Cylindrosporium matricariae, Erysiphe cichoracearum (powdery mildew), E. polyphage, Halicobasidium purpureum, Peronospora leptosperma, Peronospora radii, Phytophthora cactorum, Puccinia anthemedis, Puccinia matricaiae, Septoria chamomillae, and Sphaerotheca macularis (powdery mildew).
