Yan Hu Suo
Also known as: Corydalis yanhusuo, corydalis, yanhusuo.
Yan Hu Suo stays in the library to preserve the traditional analgesic branch of the protocol, but it remains a low-tier option because the support here is mechanistic and historical rather than strongly demonstrated for hangovers.
Where this fits in the system
What it does
Yan Hu Suo is for the body-ache version of recovery: residual tension, soreness, and a sense that pain is now the main problem. It is not a core mechanism ingredient.
How it works
Where it fits
This herb belongs when headache or body pain is the main complaint after the primary recovery stack is already in place. That is why it sits in the later stages and not up front.
Higher-tier options in the same role
| Goal | Best (Tier 1) | Strong support (Tier 2) | Situational (Tier 3+) |
|---|---|---|---|
| Neurotransmitter modulation | DHM (Dihydromyricetin) | Yan Hu Suo |
Buying guidance
Use a straightforward TCM-source extract or tea product. Keep the role narrow and avoid treating it like a proven replacement for the main protocol.

Why it is Tier 4
The page exists to keep the library complete for users who want the analgesic TCM branch. It stays clearly optional because the evidence remains indirect.
