Official title

A Single Arm, Open-label Pilot Trial Examining the Effects of Pau d' Arco on Primary Dysmenorrhea in Reproductive Age Women

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

A single arm, open-label trial evaluating safety and tolerability of encapsulated Tabebuia avellanedae in 12 generally healthy women aged 18-45 with primary dysmenorrhea (PDM). This will be the first study evaluating the safety and tolerability of Tabebuia avellanedae in PDM. We also aim to collect proof-of-concept mechanistic data supporting the hypothesis that Tabebuia avellanedae reduces PGE2 concentration in vivo in women with PDM.
