Chamomilla (Matricaria chamomilla L.) is a well-known medicinal plant species from the Asteraceae family often referred to as the “star among medicinal species.” Nowadays it is a highly favored and much used medicinal plant in folk and traditional medicine. Its multitherapeutic, cosmetic, and nutritional values have been established through years of traditional and scientific use and research. Chamomile has an established domestic (Indian) and international market, which is increasing day by day. The plant available in the market many a times is adulterated and substituted by close relatives of chamomile. This article briefly reviews the medicinal uses along with botany and cultivation techniques. Since chamomile is a rich source of natural products, details on chemical constituents of essential oil and plant parts as well as their pharmacological properties are included. Furthermore, particular emphasis is given to the biochemistry, biotechnology, market demand, and trade of the plant. This is an attempt to compile and document information on different aspects of chamomile and highlight the need for research and development.[#]
Traditionally, chamomile has been used for centuries as an anti-inflammatory, antioxidant, mild astringent and healing medicine [#]. As a traditional medicine, it is used to treat wounds, ulcers, eczema, gout, skin irritations, bruises, burns, canker sores, neuralgia, sciatica, rheumatic pain, hemorrhoids, mastitis and other ailments [#]. Externally, chamomile has been used to treat diaper rash, cracked nipples, chicken pox, ear and eye infections, disorders of the eyes including blocked tear ducts, conjunctivitis, nasal inflammation and poison ivy [#, #]. Chamomile is widely used to treat inflammations of the skin and mucous membranes, and for various bacterial infections of the skin, oral cavity and gums, and respiratory tract. Chamomile in the form of an aqueous extract has been frequently used as a mild sedative to calm nerves and reduce anxiety, to treat hysteria, nightmares, insomnia and other sleep problems [#]. Chamomile has been valued as a digestive relaxant and has been used to treat various gastrointestinal disturbances including flatulence, indigestion, diarrhea, anorexia, motion sickness, nausea, and vomiting [#, #]. Chamomile has also been used to treat colic, croup, and fevers in children [#]. It has been used as an emmenagogue and a uterine tonic in women.

Indications of Chamomilla
- A cough – Where a cough is dry during sleep, tickling, irritating and mucus tastes bitter. A cough tends to be worse at night and most common in children.
- Skin irritation caused by radiation therapy (radiation dermatitis). Applying German chamomile cream (Kamillosan, AP Medical AB, Stockholm, Sweden) to the skin does not seem to prevent skin irritation caused by cancer radiation therapy.
- Common cold. Early research suggests that dissolving a German chamomile product (Kneipp Kamillen-Konzentrat, Kneipp Werke) in hot water and inhaling the steam for 10 minutes reduces common cold symptoms.
- Inflamed or irritated skin (eczema). Some research shows that applying a cream containing 2% German chamomile extract (Kamillosan, Asta Medica AG) to the skin improves inflamed or irritated skin. In fact, it might work better than creams containing 0.75% fluocortin butyl ester or 5% bufexamac. However, other research shows that applying a cream containing 10% German chamomile extract does not improve inflamed or irritated skin. The differences in effectiveness might be related to differences in creams used and the severity of eczema in patients.
- Uncontrolled urination or bedwetting (enuresis). Early research shows that applying oil infused with German chamomile to the skin above the pubic area or near the anus nightly for 6 weeks may reduce episodes of uncontrolled urination in children.
- Gum disease. Research shows that using an herbal toothpaste containing German chamomile, sage, myrrh eucalyptus, calcium carbonate, and sodium monoflurophosphate twice daily for 30 days reduces gum disease compared to pretreatment. But it doesn’t appear to work better than standard toothpaste.
- Hemorrhoids. Early research shows that applying German chamomile ointment (Kamillosan, Asta Medica AG) together with standard treatment improves bleeding, itching, and burning in people with hemorrhoids.
- Insomnia. Research shows that taking German chamomile twice daily for 28 days does not improve sleeping problems in people with insomnia.
- Sores in the mouth (oral mucositis). Using a German chamomile mouth rinse (Kamillosan Liquidum, Asta Media AG) might help prevent or treat sores in the mouth caused by radiation therapy and some types of chemotherapy. However, it doesn’t appear to prevent mouth sores caused by 5-fluorouracil. Using a mouth rinse containing German chamomile and peppermint oil before and during stem cell transplantation might help treat mouth sores caused by high-dose chemotherapy that is used before stem cell transplantation. However, it doesn’t appear to prevent these mouth sores from occurring.
- Skin breakdown around colostomy appliances (peristomal lesions). Early research shows that applying a German chamomile compress to areas of skin breakdown around colostomy appliances decreases the amount of time needed for skin lesions to heal by about 5 to 6 days compared to applying 1% hydrocortisone cream.
- Vaginal infection (vaginitis). Early research shows that flushing the vagina with a German chamomile extract in water reduces symptoms such as odor and swelling in women with vaginal infections.
- Wound healing. Research shows that applying a German chamomile product (Kamille Spitzner, W. Spitzner Arzneimittelfabrik GmbH) to wounds for 14 days reduces wound size after 4 days of treatment but does not affect wound healing approximately 3 weeks after tattoo removal.
- Diarrhea – Where it is painful, stools are greenish and smell of rotten eggs and is common in teething children.
- Flatulence – When the stomach tends to be bloated.
- Insomnia – When accompanied by sleepiness. Insomnia can be a result of pain, stimulants such as tea/coffee, anger, or too much chamomilla tea – this includes in the case of babies. This can also occur in people who are restless.
- Joint pain – Where the pain is violent and tends to be accompanied by numbness. The pain can cause the person to get out of bed during the night, as walking around eases it a little.
- Labor pains – Where the pains are distressing and severe, to unbearable. This is when the person says things like they cannot bear the pain and they want to die. Can be very angry and impatient while cervix could be slow to dilate.
