St John's Wort

Carrier Oil

Hypericum perforatum

Origin: Europe (particularly Mediterranean and Central Europe)

About

St John's Wort carrier oil is an infused oil, typically made by macerating Hypericum perforatum flowers in a base oil such as olive or sunflower, giving it a distinctive deep red colour from the hypericin content. It has a medium-to-heavy texture with a characteristic herbaceous, slightly resinous aroma and leaves a mild residue on the skin. It is particularly valued in massage therapy for nerve pain, bruising, muscular tension, and inflammatory conditions along nerve pathways such as sciatica.

St John's Wort oil has been used medicinally since ancient Greek times, with Hippocrates and Dioscorides documenting its wound-healing and nerve-soothing properties. It was traditionally harvested around the feast of St John the Baptist (June 24th), when the plant is in full bloom, and was used by herbalists across Europe to treat bruises, burns, and nerve pain. During the medieval period it was also employed as a protective herb, hung in doorways to ward off evil, and its bright red infused oil was considered a powerful healing remedy.

Pairings (59)

Caution
Lemongrass

Lemongrass has a higher sensitisation risk and its sharp citrusy aroma can compete strongly with St John's Wort's earthy character; use with care and at low dilution.

Caution
Neem

Neem's very strong, pungent odour can overwhelm St John's Wort's subtle aroma and may cause skin sensitivity in some clients; use only in very small proportions.

Caution
Clove Bud

Clove bud carries a high sensitisation risk and can be dermally irritating; use only at very low dilution alongside St John's Wort and avoid on sensitive skin.

Caution
Bergamot

Both St John's Wort and bergamot (unless FCF) are photosensitising, and combining them significantly elevates the risk of skin phototoxicity — use only FCF bergamot and advise sun avoidance.

Caution
Basil ct. methylchavicol

Basil ct. methylchavicol carries a higher sensitisation risk and its more stimulating profile may conflict with St John's Wort's calming nerve-soothing action.

Caution
Peppermint

Peppermint's strong cooling action and sensitisation risk require careful dilution alongside St John's Wort; avoid on sensitive skin types and use at low concentrations.

Caution
Castor

Castor oil's very heavy, viscous consistency can inhibit the absorption of St John's Wort's active compounds; use only in very small proportions if included.

Caution
