Christina Loosestrife / Lysimachia

OVERVIEW

What This Record Covers

Christina Loosestrife, called Jin Qian Cao, is the dried whole herb of Lysimachia christinae, a creeping perennial herb of the primrose family (Primulaceae) that grows in moist fields and along streams across central and southern China. The plant has creeping stems and round to oval leaves, and the whole above-ground herb is harvested, washed, and dried for use. In trade it appears as cut dried herb, whole plants, teas, granules, and extracts. Because several similarly named plants are traded as “money grass,” the whole herb, the leaves, and similarly named Lysimachia species need to be kept distinct on the label.

IDENTIFICATION

Identification and Image Notes

The plant has creeping stems and round to oval leaves, and the whole herb, leaves, and similarly named Lysimachia species need to be kept distinct. The dried herb is green to gray-green with thin wiry stems and small rounded leaves, and it is usually sold as cut material. The round leaves are an orientation clue, but the species and the harvested part should be confirmed with the label, because several unrelated “money grass” plants are traded under the same name.

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 Christina Loosestrife for urinary stones, gallbladder and damp-heat language, and fluid movement, and it appears in formulas aimed at urinary stones and damp-heat presentations of the urinary and biliary systems, often combined with other urinary herbs in stone-related decoctions. Classical texts describe it for promoting the passage of stones and clearing damp-heat, always within a pattern-based framework. The stone vocabulary is historical and does not establish that any product dissolves stones, and severe colicky pain, fever, chills, or blood in urine requires medical assessment rather than self-treatment, since these may indicate obstruction or infection.

PROCESSING CONTEXT

Raw Material, Processing, and Product Form

The herb is collected, washed, cut, and dried, and teas, granules, and extracts are also sold. The product form and source region affect the record, and each form should carry its own concentration details.

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.

COMPARISON

How This Entry Differs

Compare Christina Loosestrife with Alisma Rhizome for the whole-herb versus rhizome identity, and with Capillary Wormwood for the liver-and-damp-heat end of the vocabulary. Loosestrife is distinguished by its stone-related history and its creeping whole-herb form.
