The remarkable chamomile was named the 2025 Herb of the Year™ by the International Herb Association. Chamomile comes in many varieties, but two stand out in herbalism and aromatherapy: Blue chamomile (Matricaria recutita) and Roman chamomile (Chamaemelum nobile). While both offer calming and anti-inflammatory properties, they have distinct botanical characteristics, medicinal benefits, and uses.
Botanical Characteristics
Blue Chamomile (Matricaria recutita)
- Also known as German chamomile
- Annual plant with smooth stems
- Small, daisy-like flowers with a conical, dome-shaped center
- Strong, slightly bitter aroma
- Essential oil has a deep blue hue due to chamazulene, a powerful anti-inflammatory compound
Roman Chamomile (Chamaemelum nobile)
- Perennial plant with slightly hairy stems
- Daisy-like flowers with a flat, solid yellow center
- Strong apple-like scent
- Often used in teas and skin care for its gentle, soothing properties
Key Differences Between Blue and Roman Chamomile
Uses and Benefits
Blue Chamomile:
- Known for its powerful anti-inflammatory effects, making it ideal for supporting skin conditions like eczema and acne
- Frequently used in essential oil blends to maintain calm, clear skin
- Excellent for digestive support when taken as a tea or extract
Roman Chamomile:
- A classic ingredient in herbal teas for relaxation and sleep support
- Gentle enough for children and those with sensitive skin
- Commonly found in skincare and haircare formulations for its soothing properties
Both varieties contain trichomes—tiny hair-like structures that store and release essential oils. These fragile structures require careful harvesting and distillation to preserve their potency.

Identifying the Right Chamomile for You
If you’re looking for a potent anti-inflammatory essential oil, Blue chamomile is the best choice. If you prefer a gentler herb for teas or skincare, Roman chamomile is a better fit. Understanding these differences ensures you get the most out of chamomile’s therapeutic potential.
