Understanding Chamomile

Chamomile, a flower resembling a daisy, is commonly used in teas and supplements.[1] There are two primary types: German chamomile and Roman chamomile.[2] Both kinds have been used in traditional medicine for a long time.[3]

Chamomile tea is often consumed to promote relaxation or help with sleep.[4] This herb has become more popular recently, with many people using it as a natural option for different health-related issues.

Chamomile has been used by herbalists for centuries.[5] Ancient Egyptians valued it as a general remedy for many ailments.[6] Today, chamomile is still frequently used in herbal mixtures and skin care products.

Chamomile’s Active Compounds

Chamomile contains several active compounds.[7] These substances are thought to contribute to its possible health benefits. Understanding these compounds helps explain how chamomile may affect the body.

These compounds interact with various systems in our bodies. For example, apigenin may bind to brain receptors, which could produce calming effects.[8] Chamazulene and bisabolol may work to reduce inflammation[9] , and flavonoids may help protect cells from damage.[10]

Benefits of Chamomile

Stress and Anxiety Relief

Chamomile may help lower stress and anxiety.[11] Many individuals report feeling more relaxed after drinking chamomile tea. This effect is often attributed to the apigenin present in the herb.

Research supports the calming effects of chamomile. A study in 2016 showed that long-term use of chamomile reduced anxiety symptoms.[12] Another study demonstrated that chamomile extract decreased anxiety in individuals with generalized anxiety disorder.[13]

Sleep Aid

Chamomile may help improve both sleep quality and duration.[14] Its mild sedative effect can assist people in falling asleep more easily. Many people incorporate chamomile tea into their bedtime routines.

Research on chamomile for sleep has shown varied results. A small study indicated that chamomile tea improved sleep quality in older adults.[15] However, more extensive studies are needed to verify these findings.

Digestive Health

Chamomile has a long history of being used for digestive problems. It might help in calming upset stomachs and reducing bloating. Some people drink chamomile tea to relieve indigestion or nausea.

Current research lends some support to these traditional uses. A review of studies concluded that chamomile is effective for treating diarrhea and colic in children.[16] Another study suggested that chamomile may help with acid reflux.[17]

Common Side Effects

Drowsiness

Chamomile can cause drowsiness in some individuals.[18] This effect is due to its sedative properties. While this can be helpful for sleep, it may also impact daily activities.

Drowsiness from chamomile may affect:

• Driving ability
• Work performance
• Reaction times

People should avoid using heavy equipment after consuming chamomile.[19] It is best to use chamomile in the evening or when focus isn’t needed.

Allergic Reactions

Some people may have allergic reactions to chamomile.[20] The risk of this increases in those with allergies to related plants.[21] People with allergies to ragweed, chrysanthemums, or daisies should be cautious.

Symptoms of a chamomile allergy can include:

• Skin rashes or hives
• Itching or swelling
• Difficulty breathing
• Anaphylaxis (in severe cases)

Anyone who experiences these symptoms should stop using chamomile. Seek immediate medical attention for severe reactions.

Interactions with Medications

Chamomile may interact with certain medications.[22] These interactions could lead to increased side effects or reduced effectiveness of the medication.[23] Consulting a healthcare provider before using chamomile supplements is important.

Always tell your doctor about any herbal supplements you are taking. This precaution helps to prevent potentially harmful drug interactions.

Less Common Side Effects

Skin Reactions

Using chamomile topically can sometimes cause skin irritation. This reaction is more common in people who have sensitive skin. Factors that may increase the risk include:

• Concentration of chamomile in the product
• Duration of skin contact
• Individual skin sensitivity

If you notice redness, itching, or swelling after using chamomile products, stop using them. These symptoms usually go away quickly once the product is removed.

Hormone-Related Effects

Chamomile might affect hormone levels in some people.[24] This is because it contains compounds that can mimic estrogen in the body. While these effects are generally mild, it’s something to consider for specific groups.

People with hormone-sensitive conditions should use caution. These conditions include:

• Some types of breast cancer
• Uterine fibroids
• Endometriosis

Consult a healthcare provider before using chamomile if you have these conditions. They can advise you on whether chamomile is safe for you.

Chamomile During Pregnancy and Breastfeeding

The safety of chamomile during pregnancy is not fully known.[25] Some experts advise against its use, particularly during the first trimester.[26] Others consider occasional use of weak chamomile tea to be safe.

Current research on chamomile use during pregnancy is limited. No major risks have been identified. However, the herb’s effects on fetal development haven’t been fully explored. Pregnant women should be cautious and consider avoiding it.

For breastfeeding mothers, chamomile is generally considered safe in moderation.[27] However, consulting with a healthcare provider is always the best approach. They can provide personalized advice for your specific situation.

Chamomile for Children

Parents often consider using chamomile for children’s health issues.[28] It’s frequently used for colic, teething pain, and sleep problems. While generally considered safe, some precautions are needed.

Using age-appropriate dosages is important when giving chamomile to children.[29] For infants and toddlers, very weak tea is typically recommended. Older children may have slightly stronger tea or small amounts of a supplement.

Precautions for parents using chamomile with children:

• Start with very small amounts to check for allergies
• Avoid giving chamomile to children with plant allergies
• Don’t use chamomile as a substitute for medical treatment
• Consult a pediatrician before using chamomile supplements

Proper Dosage and Administration

There’s no standard dosage for chamomile.[30] The right amount to use depends on factors such as age, health, and the form of chamomile you’re using. General guidelines can help ensure its safe use.

For tea, most adults can safely consume 1-4 cups daily.[31] Chamomile supplements are available in various forms and strengths. Follow the manufacturer’s instructions or speak with a healthcare provider for dosage advice.

Steps for preparing chamomile tea:

1. Boil fresh water
2. Place 1-2 teaspoons of dried chamomile flowers in a tea infuser
3. Pour hot water over the flowers
4. Steep for 5-10 minutes
5. Remove the infuser and enjoy

Quality and Purity Concerns

Choosing high-quality chamomile products is essential. Low-quality supplements may contain contaminants or unlisted ingredients.[32] These could lead to unexpected side effects or health risks.

Potential issues with low-quality chamomile products include:

• Pesticide residues
• Heavy metal contamination

Tips for selecting reputable chamomile sources:
