Bishop's weed/Drug Interactions:

  • Anticoagulants and antiplateletsAnticoagulants and antiplatelets: According to a review, photoreactive furocoumarins (psoralens) have been identified in bishop's weed (2).
  • Cytochrome P450 metabolized agentsCytochrome P450 metabolized agents: Theoretically, bishop's weed may increase the effects of drugs metabolized by cytochrome P450. The bergapten constituent of bishop's weed is the same constituent as in grapefruit and bitter orange, which inhibits cytochrome P450.
  • Photosensitizing agentsPhotosensitizing agents: According to a review and case reports, bishop's weed may be photoreactive and phototoxic, potentially causing photosensitivity (10), phototoxic skin damage (2), contact urticaria (7), phototoxic dermatitis (7; 4), and pigmentary retinopathy (8).
