Homeopathy
Extensive research over decades demonstrates that homeopathy produces no effects distinguishable from placebo. Multiple systematic reviews and meta-analyses show positive findings cluster in low-quality studies and vanish when only high-quality trials are analyzed. The practice lacks biological plausibility, with remedies diluted beyond Avogadro's limit containing no active molecules.
In the highest-quality trials with adequate blinding and sham controls, homeopathy consistently fails to show effects distinguishable from placebo—across diverse conditions including allergies, ADHD, anxiety, respiratory infections, and dementia.
Yoga
Yoga has validated evidence for chronic low back pain relief, anxiety and depression reduction, blood pressure lowering in prehypertension/hypertension, and physical function improvements in older adults. These benefits are supported by multiple meta-analyses with thousands of participants. Effects are generally comparable to other exercise interventions rather than superior. Evidence for other conditions (cancer pain, PTSD, metabolic syndrome) is weaker or mixed.
Yoga is validated for four core applications: chronic low back pain, anxiety/depression, blood pressure reduction, and physical function in older adults—with effects generally equivalent to but not superior to other exercise modalities.
