Understanding Chamomile: Its Origins and Properties
Historical Background and Traditional Uses
Chamomile, belonging to the Asteraceae family, has been a staple of traditional herbal medicine for millennia. Used in ancient Egypt, Greece, and Rome, chamomile was prized not only for its pleasant aroma and taste but also for its broad therapeutic properties. Historically, chamomile tea was a common remedy for digestive issues, stress relief, and inflammation. Today, chamomile is widely used in herbal teas, tinctures, and topical preparations.
Botanical Profile and Key Constituents
The two most commonly used varieties are German chamomile (Matricaria recutita) and Roman chamomile (Chamaemelum nobile). Both species share similar bioactive components:
- Flavonoids (e.g., apigenin, luteolin): These potent antioxidants help neutralize free radicals.
- Terpenoids (e.g., bisabolol, chamazulene): Responsible for chamomile’s anti-inflammatory and soothing properties.
- Essential Oils: Contribute to the herb’s characteristic aroma and may help relax ocular muscles.
- Phenolic Acids: Enhance the overall antioxidant capacity and support cellular protection.
The concentrated bioactive profile of chamomile makes it a compelling candidate for supporting eye health, especially in an era of increased screen time and environmental stress.
Extraction and Supplement Forms
Chamomile is available in multiple forms to suit various needs:
