Where to start

Older Than the Prescription

The practices that were medicine first

Long before a single molecule was isolated and patented, people healed each other with touch, breath, attention, movement, and ceremony. The 5,000-year-old Ayurvedic tradition of Abhyanga, the 2,700-year-old Chinese manual therapy of Tui Na, the 2,500-year-old Buddhist contemplative lineage that became modern mindfulness, the 5,500-year-old peyote ceremony of the peoples of the Americas. These are not alternative medicine. They are the original medicine, and the clinical research of the last fifty years has, in case after case, caught up to what these traditions already knew. Gathered here are the entries whose lineage runs deepest, told with the origin culture named and placed first.

When the Practice Works but the Story Is Contested

The treatment is real. The mechanism is fought over.

One of the hardest ideas in this library is also one of the most important: a therapy can produce real, measured benefit while the theory invented to explain it remains scientifically wrong or unproven. EMDR resolves PTSD, but the eye movements may not be the active ingredient. Polyvagal Theory shaped a generation of trauma care, yet its core neuroanatomy is under sustained challenge. Acupuncture relieves specific pain, while sham needling often works just as well. The honest move is to hold the clinical finding and the mechanistic claim as two separate questions, each with its own evidence level. That is what these entries do.

The Intervention No One Sells

Other humans are medicine, and no industry profits from it

Social isolation carries a mortality risk comparable to smoking. Purpose in life predicts lower dementia risk and longer survival. Peer support changes recovery outcomes. The evidence that human connection, belonging, and meaning are protective is among the strongest in all of public health, with some of the most replicated mortality findings on record. And yet this is the one category in wellness with no supplement company, no device maker, and no pharmaceutical firm behind it. That absence is exactly why it is systematically underfunded and underrepresented. This collection corrects for that gap.

The Longest Research Ban in Medicine

Forty years of prohibited research, now reopening

When the United States placed psilocybin, MDMA, and related compounds in Schedule I in 1970, it did more than restrict access. It halted medical research into a class of substances that Indigenous peoples had used in healing for thousands of years and that early clinical work had found genuinely promising. The gaps that ban left in the literature are themselves evidence, not about the compounds, but about how political decisions shape what science is allowed to ask. These entries document the suppression as historical fact, the ancient lineages that long predate it, and the research frontier now reopening.
