Ban Xia
Also known as: Pinellia ternata, prepared pinellia.
Ban Xia stays in the site because nausea is a real recovery subtype and the full-coverage protocol preserves that branch, but it remains clearly optional and low-tier due to limited direct evidence.
Where this fits in the system
What it does
Ban Xia is a niche anti-nausea support ingredient for mornings where queasiness is the main problem. It sits in the optional recovery layer only.
How it works
Where it fits
This herb is for the person whose morning is dominated by nausea rather than fatigue, anxiety, or headache. That narrow use case is exactly why it appears late in the protocol.

Buying guidance
Use only properly prepared Ban Xia from a reputable TCM source. This is a specialized herb and should not be improvised from unknown products.

Why it is Tier 4
Ban Xia helps keep the symptom-suppression branch complete, but the site does not overstate the evidence. It is there for coverage, not dominance.
