OVERVIEW
What This Record Covers
Plantain Herb, called Che Qian Cao, is the dried whole herb of Plantago asiatica, the Asiatic plantain, a low perennial of the plantain family (Plantaginaceae) that grows in lawns, roadsides, and damp ground across Asia. The plant forms a basal rosette of ribbed leaves with a slender flower spike, and the whole above-ground herb is harvested, washed, and dried for use. In trade it appears as cut dried herb, whole plants, teas, and extracts, and the seed of the same plant is a separate medicinal material. Leaf, seed, and whole-herb products are separate records even when the common name overlaps.

IDENTIFICATION
Identification and Image Notes
Plantain forms a basal rosette of ribbed leaves with a slender flower spike, and leaf, seed, and whole-herb products are separate materials even when the common name overlaps. The leaves have prominent parallel veins, and the flower spike is thin and inconspicuous, while the seed capsules are small and easily missed. The ribbed leaves are an orientation clue, but the stated part and species should be confirmed with the label, because the seed is a separate medicinal material.
Images are for orientation only, not definitive species authentication; confirm species, part, source, and labeling with a qualified professional or authoritative monograph.
TRADITIONAL CONTEXT
Traditional Use in Context
Traditional records discuss Plantain Herb for urinary and fluid movement, cough and phlegm, eye, and heat-related historical descriptions, and it appears in formulas aimed at urinary discomfort, cough, and damp-heat presentations, such as Ba Zheng San, where the whole herb is paired with other urinary herbs. Classical texts describe it for promoting urination and clearing damp-heat, always within a pattern-based framework. The urinary vocabulary is historical, and a diuretic-sounding label cannot determine the cause of a urinary or respiratory symptom, so persistent symptoms, blood in the urine, or fever require clinical assessment.
PROCESSING CONTEXT
Raw Material, Processing, and Product Form
The whole herb is washed, cut, and dried, and seed products may be processed separately. Teas and extracts should state the plant part and concentration, because the leaf tea and a concentrated extract are not equivalent exposures.
The same name can cover a raw material, decoction piece, powder, extract, or finished product, so record the labeled form rather than assuming it; see the safety review for the questions to ask.
SAFETY REVIEW
Safety Boundaries
Review kidney disease, fluid restriction, allergy, pregnancy, and persistent urinary or respiratory symptoms, and check for interactions with diuretics or medicines affecting fluid balance. Blood in urine, fever, or new swelling requires medical assessment, and this page is educational and is not a dose recommendation.
This record is not a dose recommendation; risk depends on identity, preparation, amount, duration, contamination, other medicines, and health conditions — a traditional or “natural” label cannot establish safety. For the full framework, read the Chinese Herbal Medicine Safety Review.
COMPARISON
How This Entry Differs
Compare Plantain Herb with Alisma Rhizome and Dandelion for whole-herb versus rhizome identity, fluid language, and cooling effects. Plantain is distinguished by its leaf-based identity and its pairing of urinary and respiratory vocabulary.
