Although chamomile tea offers numerous benefits for wellness, it is essential to be aware of potential side effects.

Individual responses vary based on health status and sensitivity

Digestive sensitivity may occasionally arise during the first use of chamomile. Upset stomach or mild nausea will usually subside within a few days as your system adjusts to it. For those with sensitive digestion, I recommend starting with half-strength brews. I also recommend consuming chamomile with light snacks during the adaptation period.

To avoid potential interactions, it is essential to disclose whether you are using chamomile products to all your healthcare providers. This list of providers may include your doctors, dentist, and any specialists who manage chronic disease. A consumption log is also helpful and can consist of timing and amounts. This way, your medical team can adjust your treatments appropriately when necessary and prevent unwanted interactions.

Suppose you are diagnosed with endometriosis or other conditions that could trigger hormonal changes. In that case, use caution with knockout powders. Chamomile contains phytoestrogens that may potentially interact with estrogen receptors in the body. Track your menstrual cycles or symptoms accurately. If you are hormone sensitive, I suggest speaking with endocrinologists before any regular consumption.
