Summary
Protium heptaphyllum is a South American tree of the Burseraceae family known for producing a resin with diverse pharmacological activities, including anti-inflammatory and analgesic effects [PMID:30003594, 33800018].
Background
Protium heptaphyllum (also known as 'almecegueira', 'almacega', or 'white pitch') is a tree native to the tropical regions of South America, particularly Brazil's Atlantic Forest [PMID:30003594, 33800018, 42026118]. It produces an amorphous resin and essential oils used in various applications [PMID:30003594, 28143669].
Traditional uses
In Brazilian folk medicine, it is used to treat inflammatory conditions, hasten wound repair, and as an analgesic [PMID:30499330, 39056728, 14643690]. In quilombola communities, the resin is burned as incense to treat headaches via inhalation of the smoke [PMID:33932517].
Active compounds
The resin contains a mixture of alpha- and beta-amyrin, taraxastan-3-oxo-20-ol, and sitostenonein [PMID:30003594, 11543977]. Essential oils are rich in volatile monoterpenes, including terpinolene, p-cymene, p-cymen-8-ol, myrcene, alpha-pinene, and beta-phellandrene [PMID:28143669, 30499330, 37667500, 31780877]. The plant is also noted for its richness in flavonoids and terpenes [PMID:39452080].
Mechanism of action
The alpha- and beta-amyrin mixture may act via a naloxone-reversible manner and is associated with the TRPV1 antagonist pathway in visceral nociception [PMID:16450293]. In hepatocytes, the gum resin extract regulates proteins involved in cholesterol metabolism, including HMGCR, PCSK9, LDLR, FXR, IDOL, and PPAR [PMID:33800828]. Essential oils may disrupt bacterial cell membranes, leading to the leakage of intracellular constituents [PMID:31780877]. Alpha- and beta-amyrin have also demonstrated the ability to inhibit the NorA efflux protein in certain bacterial strains [PMID:34528866].
Clinical evidence
Evidence DVisceral Nociception
Alpha- and beta-amyrin showed dose-related significant antinociception against cyclophosphamide-induced bladder pain and mustard oil-induced nociception in mice [PMID:16450293]
Evidence DObesity
Alpha- and beta-amyrin treatment in mice resulted in lower high-fat diet-induced increases in body weight and visceral fat content [PMID:27525508]. Liposomal leaf extract was also evaluated for effects on obesity in rats [PMID:39056728, 39452080]
Evidence DAcute Pancreatitis
Alpha- and beta-amyrin significantly attenuated cerulein-induced increases in TNF-alpha, interleukin-6, lipase, amylase, MPO, and TBARS in mice [PMID:21400110]
Evidence DHypercholesterolemia/Diabetes
Alpha- and beta-amyrin reduced STZ-induced increases in blood glucose, total cholesterol, and serum triglycerides in mice [PMID:22867128]. Gum resin extract reduced cholesterol production in human hepatocytes [PMID:33800828]
Evidence DGastric Ulcer
Resin significantly attenuated ethanol-induced gastric damage in mice and reduced total acidity in pylorus-ligated rats [PMID:14643690]
Drug interactions
Synergistic effects were noted when alpha- and beta-amyrin were associated with gentamicin against S. aureus [PMID:34528866], and when essential oil was combined with amikacin against K. pneumoniae [PMID:37667500].
Evidence summary
The current evidence is primarily based on in vitro studies and animal models (mice, rats, fish), with a focus on the pharmacological effects of triterpenes (alpha- and beta-amyrin) and essential oils. No human clinical trials were provided.
