The origins and varieties of chamomile
A member of the Asteraceae family, chamomile comes in several distinct varieties, each with its unique characteristics. Among the numerous existing species, two types particularly stand out for their remarkable therapeutic properties: Roman chamomile and matricaria chamomile.
Roman chamomile: characteristics and properties
Roman chamomile, also known as noble chamomile (Chamaemelum nobile), is characterized by its modest size, reaching 10 to 30 cm in height. Native to Western Europe and North Africa, this perennial plant thrives particularly on the French Atlantic coast. Its downy foliage and characteristic green apple scent distinguish it from its cousins.
This variety stands out in particular for the composition of its essential oil, 80% rich in esters, mainly angelates. These compounds give it particularly effective properties:
- Isobutyl angelate: anti-stress and antispasmodic action
- Isoamyl angelate: anxiolytic effects
- Methyllalyl angelate: calming properties
Matricaria chamomile: particularities and uses
Matricaria chamomile, or German chamomile (Matricaria chamomilla), takes its name from the Latin "matrix", in reference to its benefits for female health. This variety, larger than its Roman cousin, can reach up to 50 cm in height. It grows naturally on soils poor in limestone, particularly in Mediterranean regions.
Particularly appreciated since Antiquity, chamomile is distinguished by its unique composition of active ingredients. Its essential oil contains chamazulene, alpha-bisabolol and alpha-bisabolol oxide. These compounds give it particularly powerful anti-inflammatory properties, particularly effective against:
- Skin allergies
- Dermatoses
- The itching
In France, the cultivation of these two varieties occupies an important place, particularly in Anjou, where nearly 300 hectares are dedicated to the production of Roman chamomile. This region also produces more than 90% of French production, thus demonstrating the economic importance of this medicinal plant.

The active compounds of chamomile
Scientific research has identified more than a hundred active compounds in chamomile, each contributing to its remarkable therapeutic properties. Let's take a detailed look at these essential components that make this plant a popular natural remedy.
Flavonoids and their effects
Flavonoids are a major group of bioactive compounds found in chamomile. Among them, apigenin, luteolin and quercetin particularly stand out. These natural molecules have powerful anti-inflammatory properties, notably by inhibiting cyclooxygenase and lipoxygenase, two enzymes involved in inflammatory processes.
Beneficial essential oils
Roman chamomile essential oil contains more than 140 identified constituents. Its unique composition includes:
- Mono- and bifunctional esters (more than 85% of its composition)
- Monoterpenes (α- and β-pinene, β-myrcene, limonene)
- Azulenes in traces
To obtain this precious oil, a careful process is necessary: 100 kg of flowers produce between 400 and 900 ml of essential oil. In the case of chamomile, bisabolol and chamazulene are the main components, known for their significant anti-inflammatory effects.
Natural antioxidants
Chamomile contains a high concentration of natural antioxidants (such as green tea) which protect the body against oxidative damage. These compounds play a crucial role in preventing oxidative stress, in particular thanks to their ability to neutralize free radicals. Studies have demonstrated that Roman chamomile oil exhibits significant antioxidant activity, particularly observable in β-carotene whitening tests.
In addition, the presence of sesquiterpenes, coumarins and bioactive phenolic compounds enhances the therapeutic potential of the plant. Umbelliferone, a specific coumarin, contributes in particular to the antioxidant and anti-inflammatory power of matricaria, while exerting a beneficial action on the vascular system.
Les bienfaits thérapeutiques prouvés
Recent scientific studies confirm the numerous therapeutic benefits of chamomile, in particular thanks to its active compounds with remarkable properties.
1 - Effects on the nervous system
The World Health Organization officially recognizes the use of chamomile infusions to treat agitation and mild cases of insomnia linked to nervous disorders. A study of postpartum women showed that those who consumed chamomile tea for two weeks slept better and had fewer symptoms of depression. Additionally, participants taking 270 mg of chamomile extract twice daily woke up less often at night and fell asleep 15 minutes faster.
2 - Action on digestion
Chamomile particularly excels in the treatment of digestive disorders. Its antispasmodic and anti-inflammatory properties effectively relieve:
- Abdominal pain and intestinal cramps
- Bloating and gas
- Nausea and indigestion
Its anxiolytic effect notably soothes stomach cramps and digestive spasms triggered by emotions. In addition, its antifungal properties contribute to the balance of the intestinal microbiota.
Anti-inflammatory properties
Preliminary research reveals that chamomile inhibits cyclooxygenase and lipoxygenase, two enzyme systems involved in inflammatory processes. This action reduces the production of prostaglandins, pro-inflammatory hormones. Furthermore, the flavonoids present in chamomile significantly improve total cholesterol levels in diabetics, as well as levels of triglycerides and LDL cholesterol.
Studies also suggest that anti-inflammatory qualities of chamomile can prevent the deterioration of pancreatic cells, a phenomenon occurring during chronic hyperglycemia. In addition, the flavones it contains have the potential to reduce blood pressure and cholesterol levels, two determining factors in the development of heart disease.
How to use chamomile effectively
To fully benefit from the virtues of chamomile, careful preparation and appropriate dosage are essential. Discover proven methods to maximize its therapeutic benefits.
Preparing the perfect brew
The success of a chamomile infusion relies on a few key steps. Start by measuring one to two tablespoons of dried flowers or one sachet per 225 ml of water. Bring the water to a boil, then pour it over the flowers. Immediately cover your cup with a saucer to preserve the precious aromatic compounds. Leave to infuse for 5 to 7 minutes to obtain optimal extraction of the active ingredients. Then, strain carefully through a fine sieve or remove the sachet. To enrich the flavor, optionally add honey or a squeeze of lemon.
Recommended dosage
The optimal daily dosage is between 2 and 4 cups per day. However, some experts recommend starting with just one cup daily before gradually increasing consumption. This approach allows individual tolerance to be assessed and the quantity to be adjusted according to personal needs.
Ideal time of consumption
Chamomile adapts perfectly to different times of the day, each corresponding to specific benefits:
- In the evening: A cup about an hour before bed promotes relaxation and prepares you for sleep. This period allows the active compounds to fully act on the nervous system.
The rooibos is also a very good drink to relax before going to bed - After meals: Consumption 30 to 60 minutes after eating optimizes its digestive effects. This time window makes it possible to effectively relieve gastric discomfort.
- In case of stress: A relaxing break with a chamomile infusion helps you find calm and serenity. The soothing properties of the plant then act as natural emotional support.
For maximum effectiveness, favor regular consumption while respecting the recommended doses. Indeed, consistency in use allows the best therapeutic results to be obtained.
