When it comes to health, the phrase 10 worst alternative treatments instantly raises red flags. Below we dive into a ranked rundown of the most dubious, dangerous, and scientifically disproven remedies that continue to circulate under the guise of “natural” medicine.
10 Worst Alternative Treatments Overview
Most of the therapies on this list are championed by proponents of so‑called “natural medicine.” Yet, more often than not, they belong to the realm of quackery—a term derived from the Dutch quacksalver, meaning “hawker of salves.” As comedian Tim Minchin quipped, “Do you know what they call alternative medicine that’s been proved to work? Medicine.” While research into alternative approaches isn’t inherently bad, once a remedy is shown to be ineffective, it should be discarded.
10 Laetrile
A chemical cousin of amygdalin—found in apricot pits, almonds, and other fruit seeds—Laetrile is touted as a miracle cancer cure. Though its exact origins are murky, it is often credited to Dr. Ernst T. Krebs Jr. Despite at least a dozen rigorous studies, none have demonstrated any anti‑tumor activity.
Proponents claim Laetrile exploits a supposed enzyme unique to cancer cells, allowing the cyanide‑laden compound to target only malignant tissue. This premise is entirely false; documented cases of cyanide poisoning and death have occurred. Because of its toxicity and lack of efficacy, Laetrile is banned from import into the United States, yet it persists in other regions worldwide.
9 Colloidal Silver
Colloidal silver is marketed as a cure‑all for ailments ranging from cancer to HIV and herpes. The product consists of microscopic silver particles suspended in liquid, taken orally or applied as a salve or injection. While silver‑based dressings can aid burn victims, oral consumption has never shown therapeutic benefit.
The primary side effect is argyria, a permanent bluish‑gray discoloration of skin, eyes, and internal organs due to silver buildup. Though not life‑threatening, argyria is irreversible. Excessive ingestion can also damage kidneys and cause neurological problems.
8 Yohimbe
Extracted from the bark of an African evergreen, yohimbe has long served as a traditional aphrodisiac. Some “experts” tout antioxidant benefits and heart‑protective properties, yet the herb can trigger dangerous side effects such as rapid heart rate and kidney failure. It entered European markets in the late 19th century as an impotence remedy, a role later eclipsed by pharmaceuticals like Viagra.
Scientific evidence for its efficacy in treating erectile dysfunction is weak at best; trials yield inconclusive or contradictory results. Consequently, yohimbe offers little therapeutic value and may act as a hazardous placebo.
7 Aveloz
Aveloz is an herbal extract derived from the sap of a Brazilian shrub, historically used for its corrosive properties. Though obscure until the 1980s, it has gained popularity as a purported cancer‑fighting agent, often diluted in water or tea. Its chemical composition remains largely unstudied.
Advocates claim it can eradicate tumors, especially facial cancers, whether ingested or applied topically. In reality, the sap can burn skin, mouth, and throat, and some studies suggest it may even promote tumor growth. While related plant extracts have shown antileukemic activity, aveloz itself offers no proven benefit.
6 Colonic Irrigation
Colonic irrigation, or colon cleansing, involves pumping large volumes of liquid—sometimes water, sometimes coffee—into the rectum via a tube. Its promoters argue the procedure “detoxifies” the body, claiming most diseases originate in the colon. The practice dates back to ancient Egypt.
Modern research, however, paints a grim picture. A Georgetown University study labeled the method “worse than useless,” noting risks such as kidney and liver failure, rectal perforation, and even permanent loss of bowel function, forcing dependence on enemas.
5 Germanium
Sold under names like Vitamin O or germanium sesquioxide, germanium is a metalloid akin to silicon. While trace amounts appear in some plants, the element is primarily used in fiber‑optic cables and solar cells. The FDA has banned its import for human consumption in the United States.
Proponents hype it as a cure for cancer, asthma, diabetes, and hepatitis, alleging it stimulates interferon production and boosts white‑blood‑cell activity. Yet only a single case study hints at any anticancer effect, while chronic use—even at recommended doses—has been linked to kidney damage and death.
4 Escharotics
Also known as black or yellow salves, escharotics are corrosive ointments claimed to “draw out” cancer or treat certain STDs. Their name derives from the scab (eschar) they create on the skin. Historically popular in the 18th and 19th centuries, they persist today.
While some agents can treat superficial skin cancers, standard medical therapies achieve near‑100% cure rates with minimal tissue damage. Escharotics, by contrast, often burn healthy tissue, leaving unnecessary scars, and lack scientific validation. Reports abound of severe injury from their use.
3 Chelation Therapy
Chelation therapy is proven effective for heavy‑metal poisoning (e.g., mercury, arsenic) by binding metals for excretion. Yet alternative practitioners misuse it for conditions like autism, injecting chemicals that bind heavy metals without solid evidence.
A Baylor University study found chelation ineffective for autism and dangerously harmful, based on the unfounded belief that mercury causes the disorder. The treatment can also strip essential minerals like calcium, leading to kidney damage and other serious complications, especially in children.
2 Cellular Medicine
Conceived by quack Matthias Rath, cellular medicine claims that micronutrients act as biocatalysts for countless cellular reactions. Rath’s organization markets special vitamin pills, but courts worldwide have sued him for false claims. He promoted the approach as cures for cancer and AIDS, yet rigorous studies show no benefit.
Rath’s most notorious episode involved marketing his “medicine” as an AIDS cure in South Africa, discouraging patients from accessing free government‑provided antiretroviral therapy and endangering thousands of lives.
1 Miracle Mineral Solution (MMS)
Created by Jim Humble—who bizarrely compared himself to Jesus—Miracle Mineral Solution (MMS) is a 28% sodium chlorite solution, primarily used in industrial bleaching. When mixed with an acid like citrus juice, it produces chlorine dioxide, a potent bleach that induces nausea, diarrhea, and severe gastrointestinal distress when ingested.
Although banned in several countries, proponents still tout MMS as a cure for autism, cancer, and AIDS, even prescribing enemas and baths with the bleach‑like mixture. Documented deaths linked to MMS underscore its extreme danger.
