Laboratory studyHumansWith hempseed oil and maritime pine bark dry extract (combined as Pelvipea)

This study tested palmitoylethanolamide together with hempseed oil and maritime pine bark dry extract (combined as Pelvipea). Its results cannot be assigned to palmitoylethanolamide alone. More combination studies.

Design
Laboratory study
Subjects
T24 human bladder urothelial cell line exposed to conditioned media from E. coli-stimulated THP-1 human macrophages
Dose used in the study
Micronised palmitoylethanolamide, hempseed oil and maritime pine bark dry extract tested individually and as a mixture (Pelvipea), at concentrations up to 230 micrograms/mL
Duration
Not stated in the abstract
What was measured
NF-kB transcription factor levels and pro-inflammatory cytokine (IL-1beta, IL-6, IL-8) expression in urothelial cells after an inflammatory stimulus.

What the authors reported

This in vitro study found:

  • None of the ingredients reduced THP-1 cell viability.
  • NF-kB was reduced by hempseed oil, pine bark extract and the mixture at all concentrations tested, and by micronised palmitoylethanolamide from 25 to 200 micrograms/mL.
  • At 230 micrograms/mL the mixture gave the lowest IL-1beta, IL-6 and IL-8 levels of all conditions tested (fold-change 0.08, 0.01 and 0.32 respectively).

Limits of this study

An in vitro cell study; it cannot show effect on pelvic pain in people or animals. The authors declare no conflict of interest.
