It was a Tuesday night in February 1994. The emergency room at Riverside General Hospital was humming with its usual chaotic energy when a 31-year-old woman named Gloria Ramirez was brought in. She was suffering from late-stage cervical cancer and was in severe respiratory distress. What happened over the next 45 minutes didn't just defy medical logic; it launched a decade-long investigation that still leaves scientists scratching their heads today. People started passing out. Nurses felt their faces burning. The ER was evacuated. It sounds like a plot from a sci-fi horror movie, but for the staff on duty that night, the "Toxic Woman of Riverside" was a terrifying reality.
The Night the ER Went Down
When Gloria Ramirez arrived, she was tachycardic and breathing shallowly. The medical team, led by Dr. Humberto Ochoa, followed standard protocols. They administered Valium, Versed, and Ativan to sedate her, followed by anti-arrhythmic drugs. Nothing worked. As the staff fought to save her life, something bizarre began to happen.
Medical residents noticed a "oily sheen" covering Ramirez’s body. Some reported a fruity, garlic-like odor coming from her mouth. Susan Kane, a registered nurse, drew blood from Ramirez’s arm and immediately noticed a chemical smell. She passed the syringe to Julie Gorchynski, a medical resident, who noticed man-made-looking crystals floating in the blood.
Then, the dominoes fell.
Kane fainted. Gorchynski felt lightheaded, left the room to sit at a desk, and then she collapsed too. Maureen Welch, a respiratory therapist, was the third to go down. In total, 23 people fell ill, and five were hospitalized. The hospital declared an internal disaster. Most of the patients in the ER were moved to the parking lot. Despite the chaos, a small crew stayed behind to continue treating Ramirez. At 8:50 PM, after 45 minutes of resuscitation efforts, Gloria Ramirez was pronounced dead.

The Forensic Mystery and the DMSO Theory
The investigation that followed was, quite frankly, a mess. The Riverside County Coroner’s Office brought in the California Department of Health and Human Services. Two scientists, Ana Maria Osorio and Greg Braun, interviewed everyone involved. They initially floated the idea of "mass psychogenic illness"—basically mass hysteria.
The staff was livid. These were trained professionals used to blood, guts, and high-stress environments. They didn't just "get stressed" and faint.
The most credible explanation eventually came from Lawrence Livermore National Laboratory. They proposed a complex chemical chain reaction that sounds almost impossible, yet it’s the only thing that fits the evidence. They hypothesized that Ramirez had been using Dimethyl Sulfoxide (DMSO) as a home remedy for pain caused by her cancer.
DMSO is a powerful solvent. When it reacts with oxygen—like the oxygen being pumped into Ramirez via a mask—it converts to dimethyl sulfone. This would explain the crystals Gorchynski saw in the blood. But dimethyl sulfone isn't toxic. The Livermore scientists argued that the electric shocks from the defibrillator could have converted the dimethyl sulfone into dimethyl sulfate.

Dimethyl sulfate is nasty. It's a potent chemical weapon. It causes corneal burns, respiratory failure, and organ damage. If this happened inside Ramirez's body, she effectively became a walking chemical hazard.
Why this theory is still debated:
- Temperature requirements: Dimethyl sulfate usually requires specific temperatures to form that aren't typically found in a human body.
- The Crystals: While dimethyl sulfone crystallizes at room temperature, some toxicologists argue the concentration needed to see visible crystals in a syringe would be lethal long before the patient reached the hospital.
- The "Oily" Skin: While DMSO can leave an oily residue, the sheer volume described by the nurses seemed extreme for a topical cream.
Broken Trust and Legal Battles
The Ramirez family never bought the chemical weapon theory. They felt the hospital was covering up a massive mistake—perhaps a gas leak or a medicinal error—and using Gloria as a scapegoat. Her sister, Maggie Ramirez-Garcia, was vocal about the fact that Gloria’s body was returned in such a state of decomposition that an independent autopsy was nearly impossible. Her heart was missing, and her organs were contaminated with fecal matter.
The family sued. The hospital stood by their staff. The legal battles dragged on for years, eventually settling out of court for an undisclosed sum. But the stigma stuck. For years, the case was used in medical textbooks as a primary example of mass hysteria, which many experts now find insulting to the medical professionals who suffered genuine, long-term health effects.
Julie Gorchynski, for instance, spent two weeks in intensive care. She developed pancreatitis and avascular necrosis in her knees, literally causing her bone tissue to die. That doesn't happen from "hysteria."

The Science of the "Garlic" Smell
One of the most consistent details from that night was the smell. DMSO users often report a strong, garlic-like taste or odor. This happens because the body metabolizes the compound into dimethyl sulfide. If Ramirez was using high doses of industrial-grade DMSO—which was common in the 90s as an "underground" cure-all—her blood would have been saturated with it.
The crystals are the "smoking gun" for many. When the nurse drew the blood into a cool syringe, the temperature drop could have caused the dissolved sulfones to precipitate out. It’s a basic chemistry lab experiment happening inside a human vein.
Lessons for Modern Medicine
We still don't have a 100% confirmed answer. The "Toxic Woman" remains one of the greatest medical mysteries of the 20th century. However, it changed how hospitals handle unknown chemical exposures.
If you're a medical professional or just someone interested in the history of medicine, there are real takeaways here regarding patient safety and "unconventional" treatments.
Actionable Insights for Safety and Awareness:
- Disclose Everything: If you or a loved one are using topical solvents or alternative "miracle" creams like DMSO, tell your doctor. These substances change your internal chemistry in ways that can interact lethally with standard emergency medications.
- Ventilation is Key: The Riverside ER was a closed system with poor air circulation that night. Modern ERs are designed with much better filtration systems to prevent the buildup of volatile organic compounds (VOCs).
- Trust the Physical Evidence: The case proves that while "mass hysteria" is a convenient label for investigators, it rarely accounts for physical symptoms like bone necrosis or crystallized blood.
- Hazmat Protocol: Most hospitals now have much stricter "decon" (decontamination) protocols for patients arriving with unknown chemical odors. It’s better to treat a patient in a tent outside than to shut down an entire wing of a hospital.
The story of Gloria Ramirez is a tragedy of a life lost to cancer, compounded by a scientific anomaly that turned a room full of healers into patients. It reminds us that the human body is a complex chemical reactor, and sometimes, under the right (or wrong) conditions, that chemistry can turn deadly for everyone in the room.
