Similar Assertions

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.

87%

Using a bee resin mouthwash for a week doesn't change the levels of important substances in saliva like pH, nitrite, or sugar levels.

83%

Using a bee resin mouthwash for a week doesn't change how well blood flows to the forearm during a temporary blood flow restriction test.

82%

Using a bee resin mouthwash for a week doesn't change the types or numbers of bacteria that produce nitrite in the mouth.

81%

Using a bee resin mouthwash for a week doesn't significantly reduce plaque buildup or gum bleeding, suggesting it might not work as well as antibacterial mouthwash for short-term oral hygiene.
