Rating (out of 5): 2

Sea Buckthorn (Hippophae rhamnoides) is increasingly explored in the context of oral health, including gingivitis. The justification for its use is supported by some scientific studies, though evidence remains preliminary and not conclusive. Sea Buckthorn berries and oils are rich in vitamins (notably vitamin C and E), flavonoids, and fatty acids, which have demonstrated antioxidant and anti-inflammatory properties. Several in vitro and animal studies have shown that Sea Buckthorn extracts can reduce markers of inflammation and oxidative stress associated with periodontal disease.

Human clinical data are limited but suggest promise. For example, a small randomized controlled trial published in the journal Phytotherapy Research (2019) found that Sea Buckthorn oil gel used as an adjunct to scaling and root planing in chronic periodontitis patients led to greater improvements in gingival index and bleeding on probing compared to standard care alone. Additionally, laboratory studies have shown antimicrobial effects of Sea Buckthorn extracts against oral pathogens such as Porphyromonas gingivalis, which plays a key role in gingivitis and periodontitis.

Despite these findings, the overall quality and quantity of evidence remain low, with few large, high-quality clinical trials. Therefore, while there is emerging scientific support for Sea Buckthorn's adjunctive role in managing gingivitis, more robust studies are needed to confirm efficacy and safety in broader populations.
