Traditional Uses
In Brazilian folk medicine Piper caldense, known locally as pimenta-d'agua or pimenta-darda, is used as a sedative, as an antidote for snakebite, and to relieve toothache (Souza et al., anatomy and microscopy study of Piper caldense as a Brazilian folk medicinal plant). Phytochemical and pharmacological work on the species has documented antifungal, antimicrobial, acaricidal, and molluscicidal activity. On the basis of this documented Brazilian folk medicinal use, the species is recorded under the other tradition.
Botanical Description
Piper caldense is a shrub of the pepper family (Piperaceae), native to Brazil, where it grows mainly in humid, shaded forest habitats and is known by the vernacular names pimenta-d'agua, pimenta-darda, and paguarandy. Like other members of the genus it has jointed, swollen-noded stems and alternate, simple, entire leaves that are ovate to elliptic with prominent venation and an aromatic, peppery scent when crushed. The minute flowers lack a perianth and are densely crowded on slender, erect to curving spadix-like spikes borne opposite the leaves, ripening into small one-seeded fruits. The plant is a modest understorey shrub of the Atlantic and adjacent moist forests of eastern and southern Brazil, and is the source of distinctive aristolactam and amide constituents that underlie its biological activity.
Active Constituents
Caldensin
N-methylaristolactam (aristolactam alkaloid)Concentration: Isolated from roots
A new natural N-methylaristolactam first reported from the roots of P. caldense. Aristolactams are the marker alkaloids of this species; the class is structurally related to aristolochic acids, so a potential nephrotoxic/genotoxic concern is noted for the plant part bearing them.
Terpinen-4-ol
Monoterpene alcoholConcentration: ~18.5% of stem essential oil
Major stem-oil component with documented antimicrobial and anti-inflammatory properties across essential oils; contributes to the moderate antibacterial activity of the stem oil.
alpha-Terpineol
Monoterpene alcoholConcentration: ~15.3% of stem essential oil
Aromatic monoterpene with antimicrobial and mild sedative/analgesic activity in general essential-oil pharmacology.
alpha-Cadinol
Sesquiterpene alcoholConcentration: ~9.8% (stem) / ~19% (leaf) essential oil
One of the dominant sesquiterpene alcohols of the leaf oil, associated with antifungal and antibacterial activity.
alpha-Muurolol
Sesquiterpene alcoholConcentration: ~9% of leaf essential oil
Sesquiterpene alcohol contributing to the antimicrobial profile of the leaf oil.
Pentadecane / Valencene
Aliphatic hydrocarbon / sesquiterpeneConcentration: Pentadecane ~35.7% and valencene ~10.5% of root essential oil
Principal volatiles of the root oil, which showed the strongest (though still moderate) antibacterial activity of the three tissues examined.
Preparation Methods
Folk decoction / infusion
Parts: leaves, roots, aerial parts
In Paraiba, northeastern Brazil the plant (vernacular pimenta-d'agua, paguarandy) is used in folk medicine as a sedative, as an antidote for snakebite and for toothache. Caution: the roots contain aristolactam alkaloids (caldensin), a chemical class related to nephrotoxic and carcinogenic aristolochic acids; internal use of the root, especially prolonged, is not advisable.
Essential oil (steam distillation)
Parts: leaves, stems, roots
Steam-distilled essential oils of the three tissues have shown moderate-to-weak antibacterial activity (MIC ~325-750 ug/mL) and are studied for topical antimicrobial potential rather than internal use.
