In 1920, Hungarian physician Béla Schick ran a highly questionable experiment: he asked several women, some on their periods, to briefly hold flowers.

00:18

Then, without proper controls and relying solely on his own observations, he claimed that the blooms held by the menstruating women wilted more quickly.

00:29

Schick’s explanation for this was not only unscientific, but also played into age-old myths about periods.

00:36

He concluded that menstruating women’s bodies released toxins, excreted in sweat and blood, that can kill plants.

00:45

While it unfortunately took decades to debunk Schick’s so-called menstrual toxin hypothesis, some good did come from this work— the idea prompted investigations into the composition of menstrual fluid, eventually leading to a discovery that helped explain a very real problem: period cramps.

01:07

Anywhere from 50 to 90% of people who menstruate deal with painful abdominal or pelvic cramps during their period, a condition known as dysmenorrhea.

01:17

Individual experiences can vary, from mild discomfort, to throbbing aches, to contraction-like cramps that rival the pain of labor.
