Guides
What the named sources actually say
Free, no signup, no paywall. Each guide is built from named public sources, labels, annual lists, and published halachic literature, and lists them at the end. Where evidence was measured in a different setting, the guide says so in the same sentence as the number.
How to read these
These guides report positions and label facts; they never rule. They are written to make two conversations go better: the one with your own clinician, and the one with your own rav. Nothing here is a diagnosis, a treatment, or a ruling.

Guides now, care only after the gate
The guides are free. The waitlist is free too.
Joining the waitlist is not a purchase and not a signup for care. It sets the order people are contacted in if Refuah launches, and launch waits on a rav, a clinical co-signer, and community leadership, all still unfilled.
