Notes
Photosensitivity and drug interactions — see the herb card; avoid sun after application.
Why it works
Traditional red St John's wort oil depends on light-driven changes in dissolved pigments and an oil-soluble plant fraction; photosensitisation risk can remain relevant depending on plant part, sun exposure during maceration, and skin status. External use on intact skin only; avoid sun after application and check drug interactions on the herb card.
