Pogostemon cablin Identity & Plant Part
The botanical entity is Pogostemon cablin (Blanco) Benth., patchouli of the Lamiaceae, a bushy tropical herb with soft, hairy, square-stemmed shoots and broad leaves. The part used is the aerial part, meaning leaf and young stem. The root is not part of this patchouli extract.
Two confusions are common. Chinese guang huo xiang is this plant, while huo xiang without the guang prefix is usually Agastache rugosa, a different mint-family herb, so a specification should quote the Latin binomial. The fragrant oil holds patchouli alcohol, but a water extract keeps flavonoids and phenolic acids, named here only as constituent families.
