Using a bee resin mouthwash for a week can slightly lower systolic blood pressure (by about 2 points), but it's unclear if this small change actually improves health outcomes.

Scientific Claim

A 7-day use of 2.5% propolis mouthwash reduces systolic blood pressure by 2 mmHg in healthy adults, though the clinical significance of this small change is uncertain.

Original Statement

“However, a significant increase of plasma nitrate (+7 µmol/L, p = 0.047) and a decrease in systolic BP (−2 mmHg, p = 0.022) was observed in this group compared to the baseline.”

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

This is a randomized controlled trial with direct measurement of blood pressure before and after intervention. The p-value of 0.022 indicates statistical significance, supporting definitive language for this specific quantitative finding.

Similar Assertions

Using a special mouthwash made from bee resin for a week can raise nitrate levels in the blood, which might help lower blood pressure.
