Che Qian Zi
Also known as: Plantago asiatica seed, plantain seed.
Che Qian Zi remains in the full-coverage ingredient set as a drainage-oriented option for users who want the entire TCM branch, but it stays low-tier because the support is traditional and pattern-based.
Where this fits in the system
What it does
Che Qian Zi is an optional drainage herb for the swollen, waterlogged version of a hangover. It is part of the protocol's research-complete layer only.
How it works
Where it fits
This herb belongs in the puffy-morning subgroup, where fluid handling feels off. It is not aimed at the core mechanisms of acetaldehyde or glutathione.
Buying guidance
Buy from a specialist TCM supplier and use it as a tea-style adjunct. Keep expectations narrow: this is a symptom-pattern tool, not a universal fix.

Why it is Tier 4
The site keeps Che Qian Zi to maintain full TCM coverage and mechanism links. It remains clearly secondary because the evidence is not competitive with the main stack.
