What the interaction means
NCCIH's St. John's Wort page names several drug classes it can weaken (antidepressants, birth control, cyclosporine, anticonvulsants, heart medications, HIV drugs, cancer medications, warfarin, certain statins) -- turmeric is not among them. NCCIH's turmeric page names no specific drug interactions at all, only a general caution to consult a healthcare provider.
No documented interaction between St. John's Wort and Turmeric was identified in the authoritative sources reviewed. This is not a guarantee that no interaction exists for every dose, formulation, or individual -- it means the sources checked did not document one.
Practical context
NCCIH's St. John's Wort page and NCCIH's turmeric page were checked directly, full text, in both directions. St. John's Wort's named list does not include other herbal supplements, and turmeric's own page names nothing specific to check against.
