Appendix B — Popular Remedies That Did Not Make the Cut

These remedies are widely shared online or in folk tradition, but the research found no real evidence behind their claims. They are listed here so you know they were checked — and why they were left out.

From the popular-remedies research

• Morning lemon water to ‘detox’ or ‘alkalize the body’ — unsupported. The body detoxes via the liver and kidneys; lemon water does not change blood pH. It hydrates and provides vitamin C — that is all. (Northwestern Medicine)
• Apple cider vinegar as a fat burner / ‘belly-fat’ tonic — the Mayo Clinic states it is not likely effective for weight loss; no meaningful long-term appetite or fat-burning effect has been demonstrated.
• Garlic–lemon–ginger–honey ‘immunity shots’ to prevent or cure infections — only one small unreplicated trial of an allicin supplement capsule exists; Cochrane concluded the evidence is insufficient. No trials of kitchen tonic doses.
• Onion tea for cough — a traditional remedy with no clinical trials; any benefit is anecdotal.

From the forgotten-remedies research

• Mustard plaster — no modern efficacy trials for chest congestion or anything else; there are chemical-burn case reports. Abandoned by mainstream medicine in the 20th century.
• Onion poultice in the ear for earache — no clinical evidence; the warmth may soothe, but nothing in an onion cures middle-ear infection, and delaying care risks complications.
• Castor oil packs for ‘liver detox’ — zero clinical trials measuring any liver outcome. The only evidenced effects of castor oil are as an oral laxative.
• Garlic for the common cold — Cochrane found only one eligible trial (n=146); evidence insufficient.

More remedies that did not make the cut

Further candidates from the research that failed on evidence, safety, or both. They are listed here so you know they were considered — and rejected.

• Colloidal silver: No proven benefit for any condition; it accumulates in tissue and can turn skin permanently blue-gray (argyria).
• Essiac tea: An 8-herb Ojibwa-attributed formula with no clinical evidence against cancer; do not delay conventional treatment.
• Homeopathic arnica: Diluted past the point of containing any arnica; trials show no effect beyond placebo for bruising or pain.
• Wild lettuce ('opium lettuce'): No human evidence of opioid-like pain relief; the sedative legend outruns the data.
• 'Detox' teas: No evidence they remove toxins; many are just laxatives or diuretics — your liver and kidneys already do this job.
• Echinacea as a cold treatment: Trials favor prevention claims modestly at best; as a treatment once sick, evidence is weak — hence the book keeps it out.
• Feverfew for migraine prevention: Early promise did not survive larger trials; evidence is now weak and inconsistent.
• Black cohosh for menopause: Large trials (including NIH-funded) found no significant benefit over placebo for hot flashes.
• Valerian alone for insomnia: Inconsistent evidence on its own — the book's hops+valerian entry covers the combination that actually has trial support.
• Milk thistle for liver disease: Well-studied and consistently disappointing for liver outcomes despite the folk reputation.
• Saw palmetto for prostate symptoms: Large NIH trial: no better than placebo for benign prostatic hyperplasia symptoms.
• Butterbur for allergies/migraine: Some efficacy signal, but pyrrolizidine alkaloid contamination has caused liver injury — risk outweighs benefit without pharmaceutical-grade processing.
