'''Chamazulene''' is an aromatic chemical compound with the molecular formula C<sub>14</sub>H<sub>16</sub> found in a variety of plants including in chamomile (''Matricaria chamomilla''), wormwood (''Artemisia absinthium''), and yarrow (''Achillea millefolium'').<ref name=Merck/> It is a blue-violet derivative of azulene formed from sesquiterpene matricin after the loss of acetate, water and carbon dioxide during the steam distillation of chamomile blossoms.<ref name=Safayhi>{{cite journal | pmid = 7997466 | year = 1994 | last1 = Safayhi | first1 = H | last2 = Sabieraj | first2 = J | last3 = Sailer | first3 = ER | last4 = Ammon | first4 = HP | title = Chamazulene: An antioxidant-type inhibitor of leukotriene B4 formation | volume = 60 | issue = 5 | pages = 410–3 | doi = 10.1055/s-2006-959520 | journal = Planta Medica | bibcode = 1994PlMed..60..410S }}</ref><ref>{{Cite journal |last1=Sah |first1=Amit |last2=Naseef |first2=Punnoth Poonkuzhi |last3=Kuruniyan |first3=Mohammed S. |last4=Jain |first4=Gaurav K. |last5=Zakir |first5=Foziyah |last6=Aggarwal |first6=Geeta |date=2022-10-19 |title=A Comprehensive Study of Therapeutic Applications of Chamomile |journal=Pharmaceuticals |language=en |volume=15 |issue=10 |pages=1284 |doi=10.3390/ph15101284 |pmid=36297396 |doi-access=free |issn=1424-8247 |pmc=9611340}}</ref> Oral ingestion of matricin results in chamazulene being found in blood plasma and artificial gastric fluid is able to convert matricin to chamazulene.<ref name=Ramadan_2006>{{Cite journal |last1=Ramadan |first1=Mai |last2=Goeters |first2=Susanne |last3=Watzer |first3=Bernhard |last4=Krause |first4=Eva |last5=Lohmann |first5=Klaus |last6=Bauer |first6=Rudolf |last7=Hempel |first7=Bernd |last8=Imming |first8=Peter |date=2006-07-01 |title=Chamazulene Carboxylic Acid and Matricin: A Natural Profen and Its Natural Prodrug, Identified through Similarity to Synthetic Drug Substances |url=https://doi.org/10.1021/np0601556 |journal=Journal of Natural Products |volume=69 |issue=7 |pages=1041–1045 |doi=10.1021/np0601556 |pmid=16872141 |bibcode=2006JNAtP..69.1041R |issn=0163-3864|url-access=subscription }}</ref>
