Timeline of Practices

When practices emerged, when they were studied, and when science reached conclusions.

Ancient Era (Before 1 CE)

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.

info

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.

Medieval Era (1 CE - 1800)

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.

info

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.

Key Insight

Notice the pattern: validated practices are predominantly ancient, refined over millennia, and studied with modern methods. Pseudoscience tends to emerge in modern times (post-1800) with commercialization as a key driver.

The 1970s-2000s saw a "commercial shift" where traditional practices were repackaged with exaggerated or invented claims for profit. Original Vastu architecture became "energy Vastu." Astrology became personalized prediction services. Always follow the money.
