"Flow" breaks menstruation's taboo with humor and historical depth. Hailed as "a movement" by January Magazine, this groundbreaking cultural exploration reveals surprising - sometimes horrifying - feminine hygiene practices throughout history. What shocking attitudes toward periods still influence modern society?
Elissa Stein, co-author of Flow: The Cultural Story of Menstruation, is a New York-based writer, graphic designer, and cultural commentator known for blending humor with incisive social analysis.
Susan Kim, her collaborator, is an Emmy-nominated playwright, TV writer, and author acclaimed for her work in graphic novels and nonfiction. Their book, a genre-defying exploration of menstruation’s historical and societal impact, merges Stein’s sharp observational wit with Kim’s narrative rigor, reflecting their shared commitment to dismantling taboos.
Stein’s earlier works include the humor anthology Chunks: A Barfology and the family guide City Walks with Kids: New York, while Kim co-authored the graphic novels City of Spies and Brain Camp.
Stein’s media appearances on The View, Dr. Oz, and FOX News amplified Flow’s reach, positioning it as a catalyst for public dialogue. The book, praised by Publisher’s Weekly for its “smart, funny, and shocking” insights, remains a trusted resource in feminist literature and menstrual advocacy.
Flow explores menstruation’s cultural and historical legacy, tracing societal attitudes from ancient myths to modern stigma. Authors Elissa Stein and Susan Kim dissect medical misconceptions (like “hysteria”), analyze menstrual product evolution, and debunk taboos around period sex. The book blends sharp humor with research to reframe menstruation as a natural, empowering process.
This book suits readers interested in feminist history, public health, or cultural anthropology. It’s ideal for those seeking to understand menstrual stigma, educators addressing reproductive health, or anyone curious about the $30 billion femcare industry’s origins. Stein’s accessible writing also appeals to general audiences tackling period-related shame.
Yes—Flow remains relevant for its critique of enduring taboos, like workplace period discrimination and “pink tax” pricing. Its analysis of historical misinformation (e.g., Victorian-era “menstrual weakness” myths) provides context for modern debates about menstrual equity. The blend of levity and rigor makes dense topics engaging.
The book dismantles ideas like menstruation causing impurity, mood swings being purely hormonal, and menopause as a deficiency. Stein cites how 19th-century doctors pathologized cycles as illnesses, while modern ads perpetuate secrecy/shame. Research shows cultural narratives—not biology—drive most stigma.
Flow traces femcare from homemade rags (1800s) to 1920s Kotex ads avoiding the word “menstruation,” to 1970s toxic shock syndrome scandals. Stein highlights how capitalism capitalized on shame—e.g., early tampon ads claiming to “prevent embarrassment.”
The book examines religious doctrines labeling menstruation “unclean,” Freudian theories linking cycles to hysteria, and modern media’s avoidance of period sex. Stein argues these taboos reinforce gender inequality by framing natural processes as grotesque.
Stein holds a BFA from the School of Visual Arts and authored Chunks: A Barfology before Flow. Her 13-year research process included analyzing medical journals, vintage ads, and interviews—blending graphic design skills with investigative rigor.
The book connects menstrual stigma to broader oppression, like 1920s employers blaming cycles for workplace incompetence or 1960s lawmakers dismissing period pain. Stein shows how menstrual equity (e.g., free products in schools) remains a feminist battleground.
Stein critiques medical frameworks labeling menopause a “hormone deficiency,” contrasting this with cultures celebrating post-reproductive freedom. The book traces how hormone replacement therapy campaigns created new anxieties about aging.
Some reviewers note the book focuses heavily on Western perspectives, with less analysis of global menstrual practices. Others argue it oversimplifies complex medical histories, though most praise its provocative storytelling.
While both tackle menstrual equity, Flow emphasizes historical/cultural analysis, whereas Period Power focuses on modern activism. Stein’s work delves deeper into advertising’s role in stigma, while Okamoto prioritizes policy changes.

Imagine a biological process affecting half the world's population-3.5 billion women experiencing it monthly for forty years-yet so stigmatized we avoid discussing it openly. While we've been busy tiptoeing around the subject, menstruation has been medicalized, commercialized, and increasingly manipulated. Modern women experience approximately 500 periods in a lifetime compared to our great-grandmothers' 160, thanks to better nutrition, fewer pregnancies, and longer lifespans. Yet despite this biological reality, we still can't discuss bleeding in polite society. Why has such a fundamental aspect of human experience remained shrouded in shame? What happens when we finally break the silence surrounding the crimson wave that connects women across generations and cultures?
Our culture has developed numerous euphemisms for menstruation-from playful ("Saddling Up Old Rusty") to grim ("the Curse"). This isn't uniquely American; the Netherlands has "the Tomato Soup Is Overcooked," Brazil has "I'm with Chico," and England has "Flying the Japanese Flag." These expressions reflect our discomfort with addressing menstruation directly. Even medical language shows bias-menstruation gets negative verbs like "decay" and "discharge," while ejaculation gets empowered terms like "spurt" and "shoot," reinforcing the false notion that menstruation is a passive failure rather than a complex biological process. This coded language significantly impacts education, with up to 10 percent of girls still experiencing their first period without understanding what's happening. Meanwhile, the "feminine hygiene" industry-worth billions annually-has co-opted the conversation, building its success on shame and secrecy.
We stand at the threshold of a brave new world regarding menstruation. The process is being chemically redefined with promises of "no more periods" through menstrual suppression, with pharmaceutical companies marketing options that let women control when and how often they menstruate. The pitch is compelling: Who wouldn't want to eliminate cramps, bloating, and PMS? Yet shouldn't we question whether menstruation universally requires elimination? The pharmaceutical industry has effectively transformed menstruation from a normal bodily function into a medical condition requiring intervention. One influential argument claims regular periods are historically abnormal and dangerous - conveniently made by a pioneer of injectable contraceptives with financial interests in these products. Most concerning is the limited research on menstrual suppression. Barr Laboratories' safety claims for Seasonale were based on just 300 women studied for only one year. Research suggests synthetic hormones may increase aggression and anxiety while dampening libido. Environmental concerns exist too, as synthetic estrogen disrupts aquatic ecosystems and may contribute to human health issues. When did a natural process become a disease requiring treatment?
Menstruation became the ultimate taboo millennia ago when societies lacked scientific explanations for women's ability to bleed regularly without harm while creating life. Ancient peoples viewed menstrual blood as life's essence. Hindu legend describes the Great Mother's "substances clotting" to birth the cosmos. Adam's name stems from Hebrew adamah, meaning "bloody clay" - though modern scholars often sanitize this to "red earth." Early science offered little clarity. Aristotle deemed menstrual blood excess material not formed into a fetus. Hippocrates claimed the uterus wandered through the body causing "hysteria" - a theory persisting for centuries. Pliny the Elder's claims that menstrual blood could kill insects, dull razors, and drive dogs mad remained unchallenged until 1492. As recently as the 1920s, menstruating women were barred from churches, mines, and food production. Even the word "taboo" derives from the Polynesian tupua, referring to menstruation - reflecting the paradoxical view of menstrual blood as both poisonous and powerful. These ancient fears continue shaping modern attitudes, despite our presumed enlightenment.
Society has long scorned emotional women, using terms like harridan, shrew, and bitch. Angry women face harsh judgment from everyone-including themselves. Many women feel shame about emotional outbursts because cultural messages suggest truly feminine women should always be patient and sweet-tempered. Despite men committing nearly all violent crimes, a woman's anger triggers disproportionate alarm. Premenstrual syndrome includes physical and emotional symptoms appearing before menstruation and disappearing after flow begins. Americans widely believe all women suffer this "monthly madness." With over 150 identified symptoms (many contradictory), most women believe they have PMS. Yet there's no scientific consensus on PMS's causes, treatments, or precise definition. Despite popular belief, no evidence shows a hormonal basis-women claiming to have PMS show identical hormonal cycles to those who don't. PMS and PMDD are largely Western constructs. While premenstrual symptoms are recognized globally, their pathologization is primarily American. The World Health Organization doesn't recognize PMDD as an illness, though the FDA does. For many women, premenstrual days actually bring increased energy, creativity, and focus. As Roseanne Barr noted, "Women complain about PMS, but I think of it as the only time of the month when I can be myself."
Femcare advertising has shaped women's attitudes by selling emotions, fantasies, and fears alongside products, using coded language like "shower fresh" and "protection." These advertisements have capitalized on centuries-old shame since the 1920s with a consistent message: menstruation is embarrassing and must be hidden, and only their products can prevent humiliation. Early advertisers transformed a natural function into a "hygienic crisis" requiring expert intervention - first creating a problem, then offering their solution. The 1980s saw fierce competition after the Toxic Shock Syndrome crisis, with companies attacking competitors' products while emphasizing their own benefits. Modern marketing targets teens online through games, quizzes, and lifestyle content. Despite superficial improvements in messaging, the underlying narrative persists: your period remains a shameful secret that must be concealed. What if we challenged this narrative? What if menstruation were treated as the normal biological process it is, rather than a monthly catastrophe requiring industrial intervention?
Commercial femcare products carry hidden risks. In 1980, super-absorbent tampons caused 38 deaths from Toxic Shock Syndrome. Though manufacturers removed harmful ingredients, TSS still affects thousands yearly. Tampons contain trace dioxin compounds that accumulate in body tissue and contribute significantly to landfills. Alternatives offer ecological and economic benefits. The menstrual cup costs about thirty dollars and lasts up to ten years, compared to the 250-300 pounds of disposables the average woman discards in her lifetime. Made of silicone or rubber, it creates a vacuum seal preventing leaks and can be worn for twelve hours without TSS risk. Many "alternative" menstrual treatments have ancient roots. Herbs like black cohosh, dong quai, and red raspberry leaf have centuries of use. Research shows calcium and manganese together reduce mood swings and cramps, vitamin E regulates hormones, and B-6 relieves bloating. Physical therapies like acupuncture, yoga, and sex help relieve menstrual discomfort. Organizations like Tampaction and Blood Sisters promote menstrual activism through education and advocacy. The path forward combines modern products with ancient wisdom while reclaiming the conversation. Breaking the silence around menstruation transforms how society views women's bodies. By rejecting shame and embracing education, we create a world where natural biological processes are understood, not hidden, and young girls are empowered by their first period - reclaiming our narrative, bodies, and power.
