  • Hypericum induces enzymes of the CYP P-450 type and P-gp type.
  • Hypericum might have MAO-inhibiting and/or COMT-inhibiting properties.
  • Many studies reported that hypericin is the main source of pharmacological effects of hypericum. However the IC50 of hypericin to inhibit MAO A and MAO B is 100- to 1000-fold higher than accessible Cmax values of hypericin after oral administration of hypericum.[3]
  • No severe interactions are known.
