Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Leptospermum scoparium, commonly known as mānuka, has a long history of traditional use by the Māori people of New Zealand and by indigenous Australians. One of its traditional applications was in oral health, particularly for soothing and supporting gum health. Māori used the leaves and bark as decoctions or mouthwashes to address oral discomfort, including sore gums and mouth ulcers. This use is rooted in the plant’s known antimicrobial properties, which were observed empirically by traditional practitioners.

From a scientific perspective, studies have primarily focused on the antimicrobial activity of mānuka honey (derived from Leptospermum scoparium nectar) rather than the plant itself. Mānuka honey has demonstrated notable efficacy against oral pathogens such as Porphyromonas gingivalis and Streptococcus mutans in laboratory studies, suggesting a potential benefit for the prevention of gum disease and dental caries. However, direct clinical evidence for the effectiveness of Leptospermum scoparium leaf or bark extracts in supporting gum health is limited.

In summary, the use of Leptospermum scoparium to support the gums is primarily justified by traditional use, with some supportive, though indirect, scientific evidence relating to its antimicrobial properties. More rigorous clinical research is needed to confirm its efficacy specifically for gum health.
