May 8, 2023 at 3:31 PM #32047 PaigeStudent I can tell you for sure that it (parsley) acts as a diuretic. Less fluid to pump, helps decrease pressure. PMR 1 user thanked author for this post. Annett May 31, 2023 at 8:23 AM #39250 Dr. Patrick JonesHomestead Instructor Yes. It’s a good diuretic which helps. It also has some vasodilating effects to relax vessels and some calcium channel effects (many blood pressure meds are calcium channel blockers). https://www.sciencedirect.com/science/article/abs/pii/S0378874119300340 Don't use herbs or combine herbs with medications or use them during lactation or pregnancy without talking with your healthcare provider. 2 users thanked author for this post.
