Chamomile, a versatile plant, is commonly incorporated into various teas, foods, essential oils, and cosmetic products. It is recognized for its potential benefits in alleviating anxiety and soothing stomach upset, with regular consumption possibly contributing to blood sugar control. While most often prepared as a tea, it can also be found in oils and tinctures.

Long-term consumption of chamomile has been associated with significant decreases in symptoms of generalized anxiety disorder (GAD) and an improvement in overall mental well-being. Beyond mental health, chamomile may also aid in digestion, providing relief for an upset stomach, resolving diarrhea in children, and alleviating colic in infants.

For individuals with diabetes, chamomile may assist in blood sugar management by decreasing A1C levels, serum insulin, total cholesterol, and low-density lipoprotein (LDL) cholesterol. Additionally, its antioxidant properties, which combat free radicals that cause cellular damage, are believed to contribute to the fight against and treatment of cancer, potentially preventing thyroid cancer and other thyroid conditions.

Topically, chamomile is frequently utilized for its anti-inflammatory effects, making it beneficial for soothing damaged skin, particularly in cases of eczema. It may also aid in the healing of diaper rash, simple wounds, bruises, burns, and sore nipples during breastfeeding.

Despite its widespread use as a bedtime aid, there is limited scientific evidence to support chamomile's effectiveness for promoting sleep. The most popular method of consumption is as a tea, though chamomile flowers can also be eaten as food, and it's available in essential oils or capsule form. Furthermore, chamomile is an ingredient in numerous cosmetic items such as deodorants, detergents, lotions, mouthwash, perfumes, shampoos, soaps, sunscreens, and toothpaste.

The Food and Drug Administration (FDA) does not regulate herbs, meaning there are no official safe dosages set for chamomile. However, consuming the amount typically found in tea, including German chamomile, is generally considered safe. Roman and German chamomile are on the FDA's list of foods generally recognized as safe (GRAS) when used as a spice, tea, seasoning, or flavoring. Less is known about the safety of more potent forms, such as essential oils.

Certain precautions are advised when using chamomile. Pregnant individuals should avoid it due to a potential increased risk of miscarriage. Those with allergies to ragweed or similar plants may experience allergic reactions to chamomile. Caution is also necessary for individuals taking blood thinners like warfarin (Jantoven, Coumadin) or the organ transplant medication cyclosporine (Gengra, Neoral), as limited information suggests potential negative interactions. It is always recommended to consult a doctor before starting any new herbal supplement.

While most people consuming chamomile in tea form do not experience negative side effects, rare instances may include diarrhea, allergic reactions, lightheadedness, and nausea.

When purchasing supplements, it is crucial to ensure the product has been independently tested, as supplements are not regulated by the FDA and can vary in quality and safety. Independent testing verifies that the supplement contains the listed ingredients and is free from harmful contaminants. Look for seals from reputable organizations like NSF International, USP (United States Pharmacopeia), or ConsumerLab.
