Chamomile is one of those classic medicinal plants that almost everyone has consumed as an infusion at some point, but many don't realize how easy it is to grow in their own garden or in a simple pot on the patio. Beyond its reputation as a home remedy for stomach ailments, it's a very versatile herb, with uses in natural medicine , cosmetics, and even in the care of other plants.
Besides being very useful, chamomile is a hardy, rewarding, and low-maintenance plant , perfect for those starting out in gardening or wanting to create a small medicinal herb corner at home. By understanding the differences between the types of chamomile, their basic care, and their properties, you can make the most of it and get the most out of it.
What is chamomile and what types exist?
When we talk about chamomile, we almost always mean common chamomile or medicinal chamomile , whose scientific name is Matricaria recutita . It belongs to the Asteraceae family , the same as daisies and sunflowers, and for a long time it was known in Latin terminology as Chamomilla , hence the word "camomile" is still often used today.
This species is also known by common names such as German chamomile, common chamomile, or sweet chamomile . It is widely distributed: it grows wild and is cultivated in much of Europe and Asia, and has also spread to regions of North America, Australia, North Africa, and South America, where it is cultivated precisely for its medicinal value.
It's important to understand that there are other very similar plants, such as Roman chamomile ( Anthemis nobilis or Chamaemelum nobile ) and field chamomile ( Anthemis arvensis ). At first glance, they can be confused with common chamomile, but they have interesting differences in their appearance, aroma, and uses in the garden.
Roman chamomile is a low-growing, creeping perennial that quickly covers the ground. Because of its growth habit and ability to form dense mats, it is sometimes used as a partial lawn replacement in gardens. However, its flowers lack the intense and characteristic fragrance of common chamomile, and maintaining a Roman chamomile lawn can be quite demanding in terms of weeding and general care.
As for the wild chamomile, the key difference lies in the flower . Its flower heads resemble those of common chamomile, but the receptacle (the central yellow part) is not hollow, whereas in Matricaria recutita it is. For medicinal and aromatic purposes, common chamomile is the variety that is specifically valued and cultivated.
What does the common chamomile plant look like?
Common chamomile is an annual herb that usually reaches between 15 and 50 cm in height . It forms erect and branched stems, relatively thin but resistant, which are covered with delicate leaves and very recognizable flowers.
The leaves are arranged alternately along the stem and are divided several times into very fine segments , giving them a feathery or finely cut appearance. This light texture contrasts with the simple shape of the flowers, which are reminiscent of miniature daisies.
The inflorescences are flower heads composed of white ray florets arranged around a central yellow disc . This yellow center corresponds to the floral receptacle, which in the case of medicinal chamomile is hollow inside, a botanical detail that helps to distinguish it from other similar species.
After flowering, the plant produces very small fruits called achenes, which contain the seeds . They are so tiny that it is impossible to collect them all, which explains why chamomile tends to self-seed wherever it thrives, appearing year after year without needing to be replanted from scratch.
Ideal conditions for growing chamomile in the garden
One of the great advantages of chamomile is that it's a very adaptable and undemanding plant . Even so, if you want it to flower vigorously and have a good concentration of active ingredients, it's advisable to provide it with suitable minimum conditions.
As for climate, chamomile prefers temperate zones and somewhat warm locations , ideally sheltered from strong winds. It thrives in spring and summer, while severe frosts can damage young seedlings or stunt the growth of plants that germinated late in the previous season.
Regarding the soil, it thrives best in light, well-drained soils with some lime content . A substrate rich in organic matter (well-decomposed humus or compost) promotes more abundant flowering. It does not do well in extremely damp or waterlogged soils, nor, at the other extreme, in excessively dry and poor soils.
Chamomile doesn't thrive in very acidic soils or in purely sandy or overly stony ground . If your soil is very heavy and clayey, or conversely, very loose and poor, it's worth improving it by adding compost and adjusting the texture so that it retains some moisture without becoming waterlogged.
As for light, it thrives in full sun or bright partial shade with a few hours of direct sunlight . It's best to avoid very strong sunlight in extremely hot climates, especially when potted, as excessive radiation and intense heat can burn the tenderest leaves and accelerate water evaporation from the potting mix.
Sowing chamomile: seeds or tea bags
The classic way to propagate chamomile is by directly sowing its tiny seeds in the ground , but there is a very practical trick for beginners: using the contents of a chamomile tea bag as a source of seeds, as long as it includes whole or chopped dried flowers with their seeds.
Whether you choose commercial seeds or seeds from your own harvest, you can sow them at two different times: autumn or spring . Autumn sowing is usually done from mid-August to mid-September. If there is sufficient warmth and rainfall during this period, the seeds germinate quickly, and the seedlings reach winter as small, well-rooted rosettes.
These rosettes spend the winter in relative dormancy and, in early spring, resume vigorous growth . As a result, they begin to flower as early as the end of May, and the yield per plant tends to be higher because they have more time to develop and branch out before entering full bloom.
Spring sowing is usually carried out between March and April, provided the soil is workable and the worst of the frosts has passed. The earlier the sowing within this window, the sooner the plant's growth cycle will begin and the less flowering will be delayed. In this case, flowering is shifted slightly later in the season and yields are usually slightly lower, although the difference is not dramatic.
Sow the seeds directly on moist soil, barely burying them . This is crucial, as chamomile seeds need light to germinate; if they are covered with too much soil, they are unlikely to sprout. Ideally, scatter them on the surface, press them down lightly with your hand or a board to ensure they make contact with the soil, and then maintain consistent moisture, but avoid waterlogging.
If you want to use the chamomile tea bag trick , the procedure is similar: open the bag, distribute its contents over a moist and well-drained substrate in a pot or directly in the garden, add a very thin layer of soil (less than half a centimeter) on top or simply press the particles against the soil, and spray water to moisten again.
To create a small greenhouse effect that encourages germination, you can cover the surface with clear plastic wrap or cling film , always leaving a few small ventilation holes. With good light (but not direct, scorching sun) and moderate but continuous humidity, the seeds usually germinate between 7 and 14 days after sowing.
Chamomile planting and management framework
While the plants are young, it's essential to keep the bed free of weeds that can compete with the chamomile. Initially, growth is relatively slow, and weeds can outpace it if not controlled regularly.
It's important to note that once established, chamomile tends to self-seed continuously in the same area . It's nearly impossible to harvest every single flower before it sets seed, so new plants are very likely to appear in subsequent years without the need for further sowing.
This characteristic can be an advantage if you want to maintain a stable patch of chamomile in the garden, but it may also require some control if you don't want it to spread too much. Selective weeding and more intensive flower harvesting at the end of the season help regulate its spread.
If planting in a pot, simply choose a container of a suitable size with good drainage and a potting mix combined with some sand and compost. Avoid waterlogging and place the pot in a bright location with a few hours of direct sunlight per day, but not where it will be scorched during the hottest part of summer.
Care of irrigation, fertilization and exposure
As for water, chamomile tolerates moderate drought better than excessive moisture . It's not a plant that requires constant and abundant watering; rather, it appreciates regular but moderate watering, allowing the top layer of the soil to dry slightly between waterings.
Overwatering, especially in pots or heavy soils, can lead to root rot and fungal growth . Therefore, many growers recommend drip irrigation or tray watering at the base of the pot, removing excess water after a while and only refilling it when the potting mix begins to dry out.
Chamomile is not particularly demanding in terms of nutrients and does not require specific fertilizers or intensive fertilization . Soil previously enriched with quality organic matter is usually more than sufficient. In fact, an excess of nitrogen fertilizer could lead to overly bushy growth at the expense of a lower flower production.
Regarding light exposure, as we mentioned, it thrives in good natural light and gentle to moderate sun . In very hot regions, it's a good idea to protect it from the strongest midday sun, especially if it's in a pot, to prevent excessive dehydration and continuous heat stress.
In cold climates, it can be grown perfectly well as long as care is taken to protect against severe frosts, especially when sowing in autumn. Light mulching and a somewhat sheltered location are usually enough for young plants to survive the winter without major problems and start off strong in spring.
Harvesting and drying chamomile flowers
The part of the plant used for medicinal purposes is the fully developed flowers or flower heads . Harvesting should be done on dry days, without rain or dew, to prevent the material from spoiling during drying.
The optimal time to harvest is when the flower heads are fully formed but not yet wilted . A helpful guideline is to wait 3 to 5 days after the flowers have opened, at which point they have finished developing but still retain all their aroma and active ingredients in good condition.
It is recommended to cut the flower heads, leaving a small piece of stem no longer than 2 cm . This facilitates handling and drying, and allows the plant to continue producing more flowers if it is still in season.
To preserve their properties, chamomile flowers should be dried as soon as possible and at controlled temperatures ; you can consult drying techniques for aromatic plants to achieve this. Ideally, the temperature should not exceed 40°C, whether in a drying rack, a dehydrator, or spread in thin layers in a shaded, airy, and warm place.
Once completely dry, store them in airtight containers in a cool , dry place away from direct sunlight. This will preserve their aroma and richness in essential oils for longer, preventing them from becoming rancid or losing their effectiveness.
Active ingredients of chamomile and its blue essential oil
Chamomile has been considered a sacred and highly valued herb in folk medicine since ancient times . In fact, in ancient Germanic traditions, it was included among the nine sacred plants bestowed by the god Odin to cure the world's ailments.
Today we know that this fame is largely due to its high content of bluish essential oil , highly concentrated especially in the flowers. Wild chamomile plants typically contain around 1,5% of this essential oil, while some cultivated and selected varieties can reach up to 3%.
The main components of this oil are substances such as chamazulene, bisabolol, and farnesene , in addition to flavonoid glycosides, bitter substances, and other compounds with proven biological activity. Chamazulene, in particular, is responsible for the oil's bluish hue and much of its anti-inflammatory action.
Thanks to this combination of active ingredients, chamomile has anti-inflammatory, antispasmodic, carminative, and disinfectant effects . It is also attributed with mild sedative properties and a modulating effect on the nervous system, which explains its popularity in relaxing infusions before bedtime.
In countries with a long tradition of cultivating this plant, varieties particularly rich in essential oil have been developed. A classic example is the Czech variety “Bohemia ,” selected since the mid-20th century and known for its high chamazulene content and the quality of its blue essential oil.
Health benefits of chamomile
Chamomile has a wide range of medicinal uses, and its relative safety makes it a staple remedy in many homes. The most common method of administration is as an infusion of dried flowers, but more concentrated decoctions, tinctures, ointments, and baths are also prepared.
For digestive health, chamomile tea is a classic remedy for relieving bloating, gas, and mild cramps . Its antispasmodic properties relax the smooth muscles of the digestive system, helping to alleviate discomfort and reducing the feeling of heaviness after large meals.
It is also used internally in cases of cough, mild colds and sore throats , either ingested as a hot infusion or used as a gargle, thanks to its anti-inflammatory and slightly disinfectant properties on the mucous membranes.
In the field of gynecology, many women use chamomile to soothe menstrual cramps or minor cycle irregularities . Its calming and antispasmodic effect helps relax the uterine muscles and reduce the intensity of spasms.
Regarding the nervous system, internal use of chamomile has a mildly calming and balancing effect . It is not a powerful sedative, but it is a useful natural aid during times of stress, irritability, or difficulty falling asleep, especially when combined with good sleep routines.
External uses: skin, eyes, mouth and more
Applied externally, chamomile is a very useful ally in skin care . Compresses and baths prepared with concentrated decoctions are helpful in cases of skin irritations, minor rashes, small burns, and mild dermatitis.
Its anti-inflammatory and disinfectant properties make it a common complement to hemorrhoid treatment , provided it is used correctly and does not replace medical follow-up in more severe cases. Sitz baths with warm chamomile infusion have traditionally been used to soothe the affected area.
Applied to superficial wounds that heal poorly, chamomile can accelerate the healing process and help prevent infection . Compresses soaked in a warm infusion often show remarkable results, provided basic hygiene measures are maintained.
In the eye area, pads or gauze soaked in a carefully strained herbal infusion are often used to relieve tired eyes, mild conjunctivitis, or styes . In this case, it is essential to filter the liquid very well to avoid any plant matter that could irritate the area.
Chamomile is also used as a gargle for oral inflammation, chronic pharyngitis, or tonsil irritation . Its mild antiseptic properties help soothe discomfort and keep the area cleaner, complementing other treatments prescribed by healthcare professionals.
Cosmetic use and hair lightening
In natural cosmetics, chamomile has earned a special place for its ability to gradually lighten hair and add golden highlights , especially in light brown or blonde hair.
Concentrated infusions of chamomile flowers are often prepared and, once cooled, added to the rinse water after washing with a neutral shampoo . It is also mixed with honey, light oils, or homemade masks to enhance its effect and add shine.
This cosmetic use requires consistency: the lightening process is gradual and gentle , so several applications are needed to notice clear changes in tone. In return, it avoids the damage that chemical dyes or strong bleaches can cause to delicate hair.
In addition to hair care, chamomile is an ingredient in soothing lotions, facial toners, and creams for sensitive skin , thanks to its anti-inflammatory and softening properties. It is particularly beneficial for reactive skin, always testing a small amount first to rule out any individual reactions.
Chamomile as a remedy for animals
The benefits of chamomile aren't limited to humans; it has also been traditionally used in home veterinary medicine to treat minor ailments in animals . Always used with caution and consulting a professional when necessary, it can be a helpful complementary treatment.
In some cases, a mild chamomile infusion is given to pets such as dogs or cats to relieve colic, digestive spasms or mild diarrhea , provided there are no other serious symptoms and under veterinary advice.
Applied externally, a warm decoction can help cleanse superficial wounds, grazes, or irritated skin in animals, just as it does in humans. Again, care must be taken to rule out allergies and ensure the injury does not require urgent professional attention.
As always when discussing animals, it's crucial to understand chamomile as a natural support and not as a substitute for a veterinary diagnosis . If the animal doesn't improve or shows worrying signs, you should consult a specialist without delay.
How chamomile protects and strengthens other plants
Interestingly, chamomile not only helps people and animals, but it can also benefit other garden plants . Its concentrated infusion is used as a natural remedy to improve the health of seedlings and prevent certain fungal diseases.
A decoction of chamomile flowers sprayed on young seedlings serves as a prevention against "damping off" , a fungal disease that causes the stems to strangle at ground level and fall over.
In addition, the presence of compounds with fungicidal, fungistatic, acaricidal and especially nematicidal action helps to strengthen the natural defenses of plants , stimulating a beneficial microbiota in the substrate and reducing the pressure of certain pathogens.
The Food and Agriculture Organization of the United Nations (FAO) includes chamomile among the effective home remedies for the ecological care of crops , precisely because of its ability to combat pests and diseases in a gentle but useful way.
Even compost benefits: watering it occasionally with a chamomile infusion has been shown to speed up the maturation process and improve the final quality . It's not an instant miracle, but it is a useful addition to an organic gardening strategy.
How to prepare a homemade fungicide with chamomile
Homemade chamomile fungicide is one of the simplest and most useful recipes you can make with this plant, and it's perfect for anyone who wants to care for their plants without always resorting to chemical products . The basic ingredients are easy to find, and the process is straightforward.
To prepare it, you only need chamomile (dried flowers or tea bags), about 2 liters of water , a deep container in which to prepare the infusion and a spray bottle or atomizer to apply it afterwards to the plants affected or susceptible to fungal infections.
First, bring the water to a boil, then add the chamomile flowers or tea bags. Let it boil briefly, then turn off the heat and let the infusion steep for several hours to allow the flavors to concentrate. Ideally, let it steep for about 24 hours.
Once cooled and filtered, pour the infusion into a spray bottle and spray the leaves and stems of the plants you wish to protect or treat. You don't need to use all the infusion at once; you can store the leftover in a cool place, but it's best not to keep it for more than a couple of weeks, as it loses effectiveness after that time.
Another way to use it is to spray the mixture on the above-ground parts of the plant for two consecutive days, and then repeat the application every two to three weeks , depending on humidity levels and disease pressure in the garden. It is important to avoid the hottest hours of the day and periods of intense direct sunlight to prevent leaf burn.
Safety, contraindications and allergies
One of the reasons chamomile is so popular is that, in typical doses, it is considered a very safe herb . It is not addictive, contains no addictive substances, and for most healthy people, moderate consumption poses no significant risks.
That said, it's important to remember that "natural" is not automatically synonymous with "harmless." Ingesting very large quantities of chamomile can cause symptoms such as nausea and vomiting, indicating that the reasonable consumption limit has been exceeded.
People with allergies to plants in the Asteraceae (Compositae) family , such as daisies or chrysanthemums, should be especially careful. Chamomile, despite its reputation as an anti-allergy remedy in some contexts, can also act as an allergen in sensitive individuals, triggering skin or respiratory reactions.
During pregnancy and breastfeeding, it is highly recommended to consult a healthcare professional before regularly consuming chamomile , especially in quantities exceeding an occasional infusion. Although generally considered a mild herb, extra caution is advised during these stages.
Similarly, those who take medication chronically or have underlying health conditions should discuss the frequent use of chamomile infusions or preparations with their doctor or pharmacist to rule out possible interactions or unwanted effects.
Overall, chamomile is a very versatile medicinal plant that can thrive in your garden as an ornamental, aromatic, and therapeutic element. With simple care, well-drained soil, moderate watering, and plenty of sunlight, you can enjoy its flowers for infusions, homemade cosmetics, and gentle remedies for the whole family, as well as take advantage of its benefits in the organic care of other garden plants.
