In a study at a university hospital in Berlin, women with endometriosis reported fewer days in pain and used fewer conventional painkillers after taking oral cannabis extracts.

Researchers followed 30 women with endometriosis and chronic pelvic pain whose symptoms had not responded adequately to hormonal treatments and painkillers. They received an oral cannabis-based medicine with similar amounts of THC and CBD alongside their existing treatments.
The median number of days in pain fell from 30 to 17 per month after three months, and average pain intensity fell from 6.81 to 4.93 out of 10. The number of days on which participants needed conventional painkillers also fell.
Participants reported improvements in fatigue, anxiety, daily functioning and overall quality of life.
