Overview
Piper marginatum is a medicinal plant from the Amazon rainforest; used to relieve
pain, swelling and fever; it is haemostatic (substance used to stem internal bleeding), repellent, antibiotic and antifungal.
It has a strong licorice (anise) smell and can be used to treat skin infections.
It has carminative and antispasmodic action.
Oils from this plant have strong cercaricidal (an agent lethal to cercaria) activity.
Traditional use in the Amazon rainforest include against liver and vesicle disease.
Constituents
It has 39 constituents of the essential oils.
Phenylpropanoids, and a new phenyloctanoid were isolated from Piper marginatum. The compounds:
3,4-methylenedioxy-1-(2E-octenyl)-benzene 2,6-dimethoxy-3,4-methylenedioxy- 1-(2-propenyl)-benzene,
1 -(1E-propenyl)-2,4,6-trimethoxybenzene: apiole; isoasarone. Croweacin (2-methoxy-3,4-methylenedioxyallylbenzene).
1-(1Z-propenyl)-2,4,6-trimethoxybenzene, 3-farnesyl-4-hydroxybenzoic acid, caryo-phylene oxide.
Pharmacology
In Brazilian folk medicine, this plant is reputed for its analgesic/anti-inflammatory
properties. The roots are used as diuretic; extract of the leaves prepared in hot water is used to treat toothache,
rheumatism, tumor and bleeding skin wounds. From the roots of Piper marginatum, cioweacin, apiole, isoasarone,
pipern~argine, marginatine and N-isobutyl-2-trans-4-trans-octadienaniide were isolated (the only amide detected
in this plant).
Since 2,4,5-trioxiphenylpropanoids as y-asarone, a-asarone and asaricin has been reported to have antimicrobial
activities against Escherichia coli and Bacillus subtilis 11, 2-methoxy- 4,5-metylenedioxypropiophenonem,
may be an explanation for some activities showed by Piper marginatum.
Dosage
Tincture: 1 - 3 ml (1 – 3 full droppers), daily.
