Gum and dental health

Limited Evidence

Small clinical studies of Barleria-containing dental products suggest improvements in gum inflammation, but evidence is limited.

How it works

Barleria species contain iridoid glycosides, flavonoids, terpenoids, and phenolic compounds. Preclinical work suggests anti-inflammatory, antimicrobial, antioxidant, and analgesic activity. Traditional uses include toothache, gum disease, joint pain, and skin infections. Human clinical evidence is limited and mostly comes from Ayurvedic literature evaluating multi-herb formulas. Barleria-containing toothpastes have been studied for gum health with modest positive findings.

Dosage

When and how to take it
