Green, peppery, and mildly astringent. Polygonum (knotweed family) carries a fresh, slightly bitter-green character with a hint of tannin — like crushed stems of a weed growing between paving stones.

Цікавий факт
Polygonum hydropiper (water pepper) contains polygodial, a sesquiterpene dialdehyde so pungent that it was historically used as a pepper substitute in regions where black pepper was unavailable. The same molecule is also found in certain marine organisms.
Отримання й хімія
Спосіб отримання
Extraction data not independently verified for perfumery-grade use. Steam distillation of certain Polygonum species (particularly P. hydropiper) is documented in phytochemistry research. The essential oil contains sesquiterpenes, polygodial (a pungent dialdehyde), and various green-leaf volatiles. Not a commercially traded perfumery ingredient at scale.

У парфумерії
Polygonum is a niche green modifier used in top-to-heart positions. It provides wild, weedy greenness — an alternative to cleaner green notes like galbanum or violet leaf. Useful in naturalistic, territory, and forest-flo or compositions. The note is typically constructed from green-leaf molecules (cis-3-hexenol, cis-3-hexenyl acetate) with peppery modifiers and mild tannin-like accents. Appears in artisanal and botanical-themed fragrance work.
