Organoleptic Characteristics

Odor aromatic, slightly empyreumatic; taste aromatic, very pungent.

Source: Culbreth, D. (1917) A Manual of Materia Media and Pharmacology, 6th ed. [2]

Macroscopic Characteristics

Plant: Perennial evergreen, dioecious climber; stem 6-9 M. (20-30°) long, articulated, smooth, woody, joints thickened, from which adventitious rootlets arise for adhering to support or taking root in the soil; leaves 10-15 Cm. (4-6') long, ovate, petioles 12 Mm. (1/2') long, acute at base and apex, entire, smooth, leathery, dark green, 5-7-nerved; flowers whitish, unisexual, sessile, elongated spikes.

Fruit: berry-like, sessile, green, then red, and when ripe yellow, nearly globular, 3.5-6 Mm. (1/7 - 1/4') broad, epicarp very thin, easily separable from the sarcocarp, grayish-black, coarsely reticulate, unilocular, 1-seeded; seed nearly white, hollow, adhering to pericarp.

Source: Culbreth, D. (1917) A Manual of Materia Media and Pharmacology, 6th ed. [3]

Microscopic Characteristics

Powder grayish black, microscopically -- blackish-brown fragments of pericarp and nearly white of endosperm and embryo, starch grains 0.001-0.003 Mm. (1/25000 - 1/8300') broad, stone cells of epicarp and endocarp with reddish-brown substance, oil cells with yellowish oil from which piperine prisms may separate.
