Traditional use: One of the oldest and most universally used medicinal herbs; employed across ancient Egyptian, Greek, Roman, and European traditions for digestive complaints, colic, fevers, anxiety, insomnia, skin inflammation, and wound healing. 

Potential benefits: Apigenin, bisabolol, and chamazulene deliver well-documented anti-inflammatory, antispasmodic, anxiolytic, carminative, and wound-healing effects; clinical evidence supports use for anxiety, insomnia, IBS, gastritis, infant colic, and topical skin conditions. 

Warnings: May cause allergic reactions in those sensitive to Asteraceae plants — patch test before topical use; may potentiate sedative, anxiolytic, and anticoagulant medications; avoid high therapeutic doses in pregnancy; generally extremely safe at typical tea-drinking quantities.
