Twinings - Pure Chamomile Tea (1 teabag)

Drink the chamomile tea plain—avoid honey, sugar, syrups, sweetened creamers, or sweetened milk alternatives, which are more likely to explain a rise than chamomile itself.

Check the ingredient label and prepare only one tea bag in water; choose an unsweetened, single-ingredient chamomile product if possible.

Have the tea alongside a small protein- and fat-containing snack, such as plain Greek yogurt, a boiled egg, or a small handful of almonds, rather than on an empty stomach.

Avoid pairing the tea with rapidly absorbed carbohydrate foods such as biscuits, pastries, toast, or sweet snacks; if you want a snack, choose berries with plain yogurt or almonds.

Repeat the test on a different day under similar conditions, and compare it with plain hot water to rule out normal sensor variation or an unrelated rise.

If the pattern is repeatable or the increase is substantial, discuss it with your clinician or diabetes-care team and review your glucose-monitor timing and medications.
