Chamomile

Chamomile

(German: Matricaria chamomilla)

(Roman: Chamaemelum nobile)

Chamomile is actually two close cousins: German chamomile (Matricaria chamomilla) and Roman chamomile (Chamaemelum nobile). Both are gentle, aromatic relaxants for tense digestion, irritability, and trouble settling, but German is the one most used in teas and anti-inflammatory skin work, while Roman is a little more distinctly bitter and spasm-relieving. Together, they’re classic “calm the gut, calm the mind” herbs.

The Herbal Glossary

Matricaria chamomilla

Phytochemistry and Pharmacology

      • Action: Strongly anti-inflammatory, wound-healing.

      • Use: Matricin is converted into chamazulene during distillation. It is especially beneficial for inflammatory conditions affecting the skin, gut, and respiratory system.

    • Action: Anti-inflammatory, carminative, antimicrobial.

    • Use: These oils are potent inflammation-soothers, making German Chamomile ideal for skin conditions, gut inflammation, and irritated mucous membranes. Chamazulene (formed during distillation from matricin) gives the oil its blue colour and contributes strong anti-inflammatory effects.

      • Action: Antioxidant, anti-inflammatory, antispasmodic.

      • Use: These compounds help reduce allergic responses, calm spasms (especially in the digestive tract), and protect cells from oxidative stress.

Chamaemelum nobile

Phytochemistry and Pharmacology

    • Action: Antispasmodic, carminative, calming.

    • Use: These esters are muscle relaxants that calm digestive spasms, menstrual cramps, and tension headaches. The oil has a softer, more floral profile than German Chamomile.

    • Action: Antioxidant, mild sedative, anti-inflammatory.

    • Use: These contribute to Roman Chamomile’s nervine action, supporting sleep, reducing anxiety, and helping to manage oxidative stress in the nervous and digestive systems.

    • Action: Mild antispasmodic, vasodilatory, anti-inflammatory.

    • Use: These help relieve muscle tension, improve peripheral circulation, and reduce discomfort from stress or inflammation.

Traditional uses

Roman Era

Roman chamomile was used for its anti-inflammatory and calming properties. It was brewed as tea to aid digestion and relaxation, and its essential oil was applied to treat skin irritations.

Anglo-Saxon Tradition

Chamomile was valued for its healing properties and was considered one of the "Nine Sacred Herbs" in the Middle Ages.

Many medicinal uses are still in use today.

Clinical Description

Roman and German Chamomile are two closely related species used by herbalists. They are valuable herbs for both children and adults.

German chamomile is the herb sold as ‘chamomile tea’ in shops. It is the sweeter-flavoured one to create gently soothing bedtime drinks and digestives.

The Roman is intensely bitter and used more for acute digestive issues and inflammation. Both herbs are bitter due to both essential oil content and sesquiterpene lactones.

Both can be used as digestive tonics, treating everything from hyperacidity to flatulence, mild indigestion to gastritis. Chamomiles are also used topically to soothe rashes and eczema and in washes and herbal creams.

The essential oil chamazulene is a potent anti-inflammatory and deep blue (hence the name, which is related to ‘azure’). The colour transformation occurs during steam distillation of the German flowers. This essential oil is added to creams for inflammatory skin conditions such as eczema.

Cultivation/Harvesting

Easily sown from seed. Pick flowers from stems or ‘comb’ them off the plant with a berry picker.
