The dangerous obsession with a 'clean' vagina: How online myths are harming women health

In Kenya’s fast-paced digital age, where TikTok trends dictate beauty standards and Instagram reels offer health advice, a silent but deeply troubling phenomenon is taking root: the rise of unregulated vaginal hygiene practices fueled by misinformation and social stigma.

At the center of this new wave is boric acid—a chemical compound now repackaged and marketed online as the latest “must-have” for female hygiene, despite its unregulated status and known risks.

Across social platforms, influencers routinely tout boric acid suppositories as magical fixes for vaginal odor, yeast infections, and pH imbalance.

Young women, like 24-year-old Tash from Nairobi, are listening. “I wasn’t sick, but everyone on TikTok was talking about it. I just didn’t want to be the one with a ‘dirty’ vagina,” she said.

This behavior, however, reflects a much deeper issue: the intersection of reproductive misinformation, systemic gaps in women’s healthcare access and the commodification of female anatomy online.

Platforms like TikTok and Instagram have become major sources of health information, especially among youth. But with little regulation, these platforms also serve as hotbeds for pseudoscience. The idea that the vagina is inherently “dirty” or in need of regular detoxification is not new—but the scale and speed with which these messages now spread is unprecedented.

Online sellers and micro-influencers, many with no medical background, promote boric acid alongside yoni pearls, herbal steams, and even garlic cloves, feeding into harmful myths under the guise of “natural healing” or “feminine empowerment.” In reality, these products—often imported without regulation—pose real dangers when misused.

Historically, boric acid has been used as an external antifungal agent and even a pesticide. While some Western medical literature does support its cautious, prescribed use in treating recurrent yeast infections, no global health authority—including the US Food and Drug Administration (FDA)—has approved it for routine intravaginal use. Even under clinical supervision, its application is restricted to very specific conditions and patients.

In Kenya, the situation is chaotic. The Pharmacy and Poisons Board (PPB) explicitly told The Standard that it does not regulate boric acid. Despite this, the compound is being sold openly on digital marketplaces, in local chemists, and even delivered via ride-hailing apps.

The unregulated availability means that anyone can buy it, use it and promote it—without oversight, dosage guidance, or an understanding of possible side effects.

Dr Moses Obimbo, an obstetrician-gynecologist and researcher at the University of Nairobi, warns that this obsession with vaginal “cleanliness” may be creating more harm than good. His research, partly funded by the Gates Foundation, is analysing the vaginal microbiome of over 1,500 Kenyan women using advanced genetic sequencing and AI tools.

“Our preliminary data shows that women who frequently use boric acid, herbal washes, or other self-administered remedies tend to have severely disrupted vaginal flora,” said Dr Obimbo. “They often present with recurring infections and, increasingly, secondary infertility.”

The vagina is self-cleaning and relies on a delicate ecosystem of beneficial bacteria—chiefly lactobacilli—to maintain a healthy pH and prevent infections. Disrupting this balance with unregulated chemicals or DIY interventions kills off the good bacteria, opening the door to bacterial vaginosis, yeast infections, and even urinary tract infections.

“Vaginal health is not a cosmetic issue—it’s the foundation of reproductive well-being,” Dr Obimbo noted.

Underlying this health crisis is a deep societal discomfort with female anatomy. Taboos, lack of sexual health education, and ingrained beliefs that a “clean” vagina is a “tight,” odorless, and perfect one are driving desperate measures.

“Women are steam-cleaning their vaginas, inserting garlic, applying yogurt, and now, using boric acid—all in pursuit of an unrealistic standard promoted by influencers,” Dr Obimbo says. “It’s a crisis of misinformation, fueled by shame.”

This shame is often compounded by the lack of accessible, affordable gynecological care in Kenya. When public health systems fail to provide adequate education and services, young women turn to the internet.

In contrast, Kenyan women are using boric acid preventively, frequently and without a diagnosis—often in combination with other unregulated products.

“Toxicity in normal applications may seem mild,” said Dr Joseph Wahome, a toxicologist and member of the Toxicology Society of Kenya.

“But we haven’t conducted localised studies on intravaginal use. What works in Europe or the US doesn’t necessarily apply here.”
