A 33-year-old mother of three had lived with whitish vaginal discharge for months but felt too ashamed to see a doctor. After watching a social media video that recommended potash alum as a home remedy, an idea a family friend also endorsed, she applied alum fragments around the vaginal opening and inserted pieces into her vagina.
Over the next three days, she developed severe lower abdominal pain, worsening vulval swelling and difficulty walking, and she went to an emergency department in Kathmandu, Nepal. What doctors found was serious enough that vulvovaginal cancer was among the first possibilities they considered. Clinicians at Shree Birendra Hospital and the Nepalese Army Institute of Health Sciences described the case in a report in the Bulletin of the National Research Centre, published Sept. 16.
An Exam That Pointed Doctors Toward the Wrong Diagnoses
The examination itself was difficult because the vaginal opening had narrowed. Doctors saw wart-like lesions around it. With a speculum, they found the vaginal lining peeling away in a diffuse pattern, along with a blackish, flaky discharge. They could also feel a hard, irregular mass at the top of the vagina.
That combination put several possibilities on the table, including genital warts, vulvovaginal cancer, a severe infection, and a retained foreign object. The cause came to light only through further detailed questioning, when the woman described the video and the alum.
Blood tests showed a white blood cell count of 16.59 thousand per microliter, well above the reference range of 4 to 11, with neutrophils making up about 80%. A pregnancy test was negative, and an ultrasound of her abdomen and pelvis was normal.
What Potash Alum Can Do to Unprotected Tissue
Potash alum, or potassium aluminum sulfate, is a crystalline mineral salt long used in traditional medicine, the authors explained. In Nepalese households, it is commonly called phitkiry. It is a strong astringent that can stop minor bleeding and has shown antimicrobial activity in laboratory studies. It has traditionally been used on wounds, and the authors noted it has also been applied for vaginal tightening.
The same properties make it hazardous inside the body. Citing a study in rabbits, the authors wrote that alum creates a strongly acidic environment of around pH 3.2 to 3.5. Unlike skin, the vaginal lining lacks a protective keratin layer, and as solid alum dissolves, it can produce very high local acid concentrations that kill tissue.
Some studies suggest alum has antifungal effects against Candida, the authors acknowledged, but its safety is unknown, and even regulated preparations can cause irritation. They stressed that its intravaginal use is not authorized and that using raw crystals is dangerous and unsupported.
Removal, Healing and a Cancer Scare Ruled Out
Under sterile conditions, doctors removed a hard alum fragment measuring about 2 by 2 centimeters, roughly three-quarters of an inch across, along with blackish dead tissue. Tissue samples went for culture and for laboratory examination to rule out cancer. The team irrigated her vagina with saline twice daily, gave broad-spectrum antibiotics to prevent infection, and provided intravenous pain relief. Her pain and swelling eased substantially, and she went home on the fourth day.
At a one-week checkup, the vaginal lining had healed, and the discharge had resolved. A Pap smear found no precancerous or cancerous cells. Tissue analysis showed degenerated tissue with a few foreign particles and no dysplasia or cancer, confirming a chemical injury from the alum.
In a statement included in the report, which the authors said was reproduced in simple language with her permission, the woman said, "I have learned that such remedies from the internet are not safe."
The authors noted important limits. The report covers one patient, follow-up lasted only one week, and neither the amount of alum used nor the content of the video could be independently verified.
Why the Warning Travels Well Beyond Nepal
The authors framed the case around stigma. A population-based survey they cited estimated that up to 34% of women in Nepal report troublesome vaginal discharge. When women feel embarrassed about symptoms like discharge, they wrote, many skip medical care and turn to unverified advice online.
That problem is not limited to Nepal. A narrative review in the Journal of General Internal Medicine identified 112 potentially misleading claims and narratives about women's reproductive health on social media and websites. Of those, 23% made medical recommendations that did not match professional guidelines, and 14% promoted alternative medicine.
U.S. guidance discourages self-treating vaginal symptoms. The federal Office on Women's Health advises against douching to get rid of discharge or other vaginal problems and recommends calling a doctor or nurse for bad-smelling discharge, itching with thick discharge, or burning, redness, and swelling. A practice guideline summary in American Family Physician notes that a patient's self-diagnosis of vaginitis is not reliable. In one study summarized in the same journal, only 34% of women buying over-the-counter yeast infection medicine had correctly diagnosed themselves.
Persistent or changing discharge has many treatable causes, and a clinician can identify which one applies. The Nepalese team also urged clinicians to ask patients about self-treatment in a nonjudgmental way, since shame can keep that history hidden.
Key Questions Answered
What happened to the woman?
After seeing a social media video, she applied and inserted solid potash alum to treat chronic discharge and developed severe pain, swelling, and tissue damage.
Why did doctors consider cancer?
They found wart-like lesions, peeling tissue, blackish discharge, and a hard, irregular mass, findings that can resemble a genital malignancy.
What is potash alum?
A mineral salt, potassium aluminum sulfate, used as an astringent. It creates a strongly acidic environment that can burn delicate tissue.
Did she recover?
Yes. After the alum was removed and she was treated, her vaginal lining healed within a week, and tests found no cancer.
Is alum a safe treatment for vaginal discharge?
No. The authors said its intravaginal use is not authorized and that raw crystals are dangerous and unsupported.
What should people with unusual discharge do?
See a clinician rather than self-treating. Federal guidance also advises against douching to manage discharge.
