A LITTLE CARE GOES A LONG WAY

Using it thoughtfully

Read the full safety context before bringing this oil into your routine.

Cited dermal maximum · leave-on: No restriction cited
Phototoxicity: Not flagged in this profile
Oxidation risk: medium

A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.

No furocoumarin-based phototoxic restriction was identified in the consulted ho-sho / ho leaf sources.

Contraindications & cautions

moderateHo leaf/Ho wood oil is very high in linalool; Tisserand & Young advise that oxidized linalool-rich oils can become skin sensitizers, and recommend not using an oxidized oil and adding an antioxidant to opened bottles. Fresh, unoxidized oil is not known to be sensitizing.
mildGeneral aromatherapy safety guidance recommends use only under qualified practitioner guidance during pregnancy, in epilepsy, or with liver disease, given the lack of dedicated human safety data for this specific oil.
mildMay act as a moderate skin irritant in some individuals; dilute before topical application and do not apply undiluted essential oil to skin without professional guidance.
