Brazilian peppertree (Schinus terebinthifolia) contains masticadienonic acid and other triterpenes that provide anti-inflammatory and antimicrobial effects. Clinical studies demonstrate its efficacy as a mouthwash for reducing gingival inflammation comparable to chlorhexidine.
Brazilian Peppertree (Schinus terebinthifolia Raddi) is an evergreen tree native to subtropical regions of South America, particularly Brazil, Paraguay, and Argentina, belonging to the Anacardiaceae family. The leaves, fruits, and bark are processed through various extraction methods including saline extraction, hydroalcoholic extraction (70% ethanol), supercritical fluid extraction, or essential oil distillation to produce bioactive extracts rich in polyphenolic compounds, lectins, and terpenoids.
Limited human clinical evidence exists, with only one phase II randomized, controlled, triple-blind trial (PMID: 23843886) testing a 0.3125% S. terebinthifolia mouthwash in 27 children with biofilm-induced gingivitis, showing significant reduction in gingival inflammation (P<0.001). No human trials for systemic uses have been conducted, with evidence primarily from preclinical studies in mice showing antitumor and anti-inflammatory effects.
Clinically studied: 0.3125% mouthwash (10 mL rinse for 1 minute daily for 10 days) for gingivitis. Preclinical dosages include 100 mg/kg saline leaf extract intraperitoneally for antitumor effects and 1-5 mg/kg lectin (SteLL) intraperitoneally. No standardized oral dosages from human trials are available. Consult a healthcare provider before starting any new supplement.
Brazilian Peppertree (Schinus terebinthifolia) is not consumed as a food ingredient but rather used as a medicinal/botanical extract; thus, conventional macronutrient profiling is not applicable in the traditional sense. Bioactive compounds are the primary nutritional/phytochemical interest: Polyphenols and tannins are the dominant bioactive fraction, with hydrolyzable tannins (including gallic acid and ellagic acid derivatives) reported as key constituents — gallic acid concentrations in bark and leaf extracts have been measured in the range of 0.5–2.0 mg/g dry weight in various preparations. Flavonoids including quercetin, kaempferol, and myricetin glycosides are present in leaf extracts at approximately 1.0–3.5 mg/g dry weight total flavonoid content. Triterpenes (including ursolic acid and oleanolic acid) are present in resin and bark fractions, with ursolic acid reported at approximately 0.3–1.2% of dry extract weight. Essential oil constituents include monoterpenes (α-phellandrene, δ-3-carene) and sesquiterpenes (germacrene D, bicyclogermacrene), comprising approximately 0.5–2.0% of fresh leaf weight. Cardanols and biflavonoids (including agathisflavone and amentoflavone) have been identified in smaller quantities. Vitamin C has been detected in fruit pulp at modest levels (~10–20 mg/100g fresh weight) but fruit consumption is not standard. Bioavailability data are limited to in vitro and animal studies; polyphenol absorption is expected to be moderate and subject to gut microbiome metabolism, with gallic acid showing relatively higher bioavailability compared to larger tannin complexes. No standardized extract concentration for clinical use has been formally established.
Brazilian peppertree's bioactive triterpenes, particularly masticadienonic acid and masticadienolic acid, inhibit bacterial biofilm formation and reduce inflammatory cytokine production. The compounds appear to interfere with bacterial cell wall synthesis and modulate immune responses through NF-κB pathway inhibition. The antimicrobial activity targets both gram-positive and gram-negative oral pathogens.
One randomized clinical trial (n=27) evaluated Brazilian peppertree mouthwash against chlorhexidine for gingival inflammation, showing comparable efficacy in reducing inflammation and biofilm accumulation. Preclinical animal studies demonstrated antitumor activity with 57.6-73.6% tumor weight reduction in sarcoma 180 mouse models. However, human cancer research is lacking, and the oral health evidence is limited to a single small-scale study. Additional clinical trials are needed to establish optimal dosing and confirm therapeutic efficacy.
Brazilian peppertree is generally well-tolerated when used topically as a mouthwash, with no significant adverse effects reported in clinical trials. However, some individuals may experience allergic reactions, particularly those sensitive to plants in the Anacardiaceae family. No specific drug interactions have been documented, but the lack of comprehensive safety data warrants caution. Pregnant and breastfeeding women should avoid use due to insufficient safety information.
