Ze Xie
Also known as: Alisma orientale, alisma, water plantain rhizome.
Ze Xie remains in the site because the drainage cluster is part of the research library's advantage, but its practical role is narrow and the evidence base does not justify a higher tier.
Where this fits in the system
What it does
Ze Xie is a pattern-specific herb for recovery that feels puffy, full, and slow. It is part of the optional drainage layer rather than the main stack.
How it works
Where it fits
Use Ze Xie when the recovery problem looks like excess fluid burden and heaviness. That makes it a later-stage support ingredient, not a default before-drinking intervention.
Buying guidance
A plain tea or decoction product from a reputable TCM vendor is enough. This should sit behind the core protocol, not replace hydration or electrolytes.

Why it is Tier 4
The herb is retained for completeness and mechanism coverage. It is not promoted as a core intervention because the evidence is still mostly traditional framing.
