Proposed Mechanism of action: There are a group of fatty acid derivatives called Prostaglandins that are produced in most tissues of the body and have varying physiologic actions.

Prostaglandins act in a manner similar to hormones, by stimulating target cells into action. However, they differ from hormones in that they act locally, near their site of synthesis, and they are metabolized very rapidly. Another unusual feature is that the same prostaglandins act differently in different tissues. The effects of Prostaglandins on the reproductive process have been well documented.

Prostaglandins have diverse actions dependent on cell type but are known to generally cause smooth muscle contraction. The vasoconstrictive and muscle constricting activities of prostaglandins contribute to the normal sloughing of the endometrial lining during menstruation. The fatty acids in the herbal formulation are synthesised into Prostaglandins which may trigger and or accelerate this process.

The herbal formulation contained in XPL7 contains some fatty acids that are converted into Prostaglandins by the body tissue and can produce their effects on a cell level in the endothelium.
