Twelve single-botanical 100ml oils weighted toward the deeper end of the range — frankincense, patchouli and sandalwood lead a list that also covers the everyday citruses and mints.
The full range: frankincense, patchouli, sandalwood, lavender, jasmine, clove, lemongrass, eucalyptus, sweet orange, lemon, vanilla and peppermint. Prices run from $23.68 for sweet orange up to $33.48 for sandalwood, tracking what the botanical itself costs rather than one flat price across the twelve.
Most of it goes into a humidifier or ultrasonic diffuser a few drops at a time; the base notes here — patchouli, frankincense, sandalwood — also hold up well from a tealight burner.
We carry more than one HIQILI 100ml listing on the store, and where a botanical appears on both, the price isn't always identical — worth a quick check before buying in quantity if a specific scent, rather than this particular page, is what you're after.
