If you’ve ever explored traditional Chinese medicine (TCM) or herbal remedies, you might have come across Lysimachiae Herba, also known as Jinqiancao or Christina Loosestrife Herb. This humble plant has been a cornerstone of TCM for centuries, prized for its ability to support liver health, ease urinary troubles, and soothe inflammation. But what exactly is it, and does it live up to the hype?
In this article, we’ll break down what Lysimachiae Herba is, its science-backed benefits, how it’s used, and what you should watch out for—all in a way that’s easy to digest, even if you’re new to herbal medicine.
What Is Lysimachiae Herba (Jinqiancao)?
Lysimachiae Herba comes from the plant Lysimachia christinae Hance, a perennial herb in the Primulaceae (primrose) family. Native to East Asia, particularly southern and central China, it’s commonly called Jinqiancao—which translates to “golden coin grass 金钱草” in Chinese, a nod to its coin-shaped leaves. In the West, it’s sometimes referred to as Christina Loosestrife Herb. Harvested in summer and autumn, the whole plant is dried, cut into segments, and used raw in various forms like teas, capsules, or ointments1.
In TCM, Lysimachiae Herba is valued for its “sweet, bland, and slightly cold” properties, targeting the liver, gallbladder, kidney, and bladder meridians. It’s traditionally used to “clear heat,” “remove dampness,” and “promote diuresis”—terms that roughly translate to reducing inflammation, detoxifying the body, and boosting urine flow2. Think of it as a natural cleanser for your internal systems, historically prescribed for conditions like jaundice, urinary stones, and swelling3.
While it’s a star in TCM, it’s less common in Western conventional medicine. You’re more likely to find it in herbal supplements or at TCM clinics in the West, available online through retailers like Amazon.
Key Benefits of Lysimachiae Herba
So, why has this herb stuck around for centuries? Both traditional wisdom and modern research point to some impressive benefits. Here’s what Lysimachiae Herba can do for you:
1. Boosts Liver Health
Your liver is like the body’s detox headquarters, filtering out toxins day and night. Lysimachiae Herba helps keep it running smoothly. Studies show it has hepatoprotective (liver-protecting) effects—think of it as a shield against damage. A 2021 study found that its ethanolic extract reduced liver inflammation in mice with acute hepatitis by calming down inflammatory signals (NCBI Study). This backs up its traditional use for jaundice and liver issues in TCM.
2. Supports Urinary Health
If you’ve ever dealt with a urinary tract infection (UTI) or kidney stones, you know how miserable they can be. Lysimachiae Herba acts like a gentle flush for your urinary system. Its diuretic properties increase urine output, helping to wash out bacteria and prevent stone formation. Research confirms it can inhibit calcium oxalate crystals—the main culprit in kidney stones—and even help push stones out of the ureter (PubMed Study). In TCM, it’s a go-to for “stone strangury” (painful urination due to stones)4.
3. Fights Inflammation
Inflammation is like a fire that flares up in the body, causing pain and discomfort. Lysimachiae Herba steps in as a natural extinguisher. Studies show it can suppress inflammatory molecules, offering relief for conditions like arthritis or skin infections. In experiments, it reduced swelling in mice and rats triggered by histamine or other irritants (ScienceDirect Article). This aligns with its TCM role in easing swelling and pain5.
4. Antioxidation and Detoxification
In TCM, Lysimachiae Herba is said to “clear heat and remove toxins,” a poetic way of saying it helps your body detox6. While we need more human studies, its antioxidant components—like flavonoids and phenolic acids—suggest it protects cells from free radical damage, a key part of the detox process7.
5. Promotes Stone Removal
Got gallstones or kidney stones? Lysimachiae Herba might help nudge them out. Research on animals shows it boosts bile flow from the gallbladder and increases ureter pressure, giving stones a little push8. Its polysaccharides even slow down crystal growth in urine, making stones less likely to form in the first place9.
Summary: Lysimachiae Herba has been valued for centuries. It benefits liver health, supports urinary function, fights inflammation, aids in detox, and promotes stone removal, backed by both traditional wisdom and modern research.
How Is Lysimachiae Herba Used?
In TCM, Lysimachiae Herba is super versatile. Here’s how it’s typically taken10:
- Decoctions: Boil 15-60 grams of dried herb (double if fresh) in water for a tea-like drink. It’s often sipped throughout the day for liver or urinary support.
- Capsules/Tablets: A convenient option if you’re not into the earthy taste.
- Ointments: Applied to the skin for swelling, injuries, or infections.
- Formulas: Mixed with herbs like Yin Chen (Artemisia scoparia) for liver issues or Shi Wei (Pyrrosia leaf) for stones.
In the West, it’s mostly used by TCM practitioners or herbal enthusiasts. You might find it in a supplement for kidney health or as part of a detox blend. Unlike Western diuretics like furosemide, it’s milder and used for less severe cases.
Dosage Tip: Start with 30-60 grams of dried herb daily11, but always check with a healthcare provider, as amounts vary by need.
Summary: Lysimachiae Herba is very versatile in TCM. It can be made into decoctions, capsules/tablets, ointments, or used in formulas. In the West, it’s used by TCM practitioners or enthusiasts, often for kidney health or detox, and is milder than Western diuretics.
Potential Risks and Precautions
Lysimachiae Herba is generally safe when used correctly, but it’s not without risks. Here’s what to keep in mind:
- Potassium Loss: Its diuretic effect can flush out potassium over time, leading to symptoms like fatigue or muscle cramps. If you’re using it long-term, consider potassium-rich foods (like bananas) or a supplement12.
- Allergic Reactions: Some people get contact dermatitis—itchy, red skin—from topical use13.
- Drug Interactions: It might clash with antidiuretic meds or drugs affecting potassium. Check with your doctor if you’re on medication.
Who Should Skip It?
- People with diarrhea (it could make it worse).
- Those with heart or kidney issues, unless cleared by a doctor14.
Before diving in, especially for long-term use, talk to a healthcare pro to make sure it’s right for you.
Summary: Lysimachiae Herba is usually safe if used properly, but has risks. Diuretic effect may cause potassium loss, leading to fatigue or cramps. Allergic reactions like contact dermatitis can occur. It may interact with some drugs. People with diarrhea, heart or kidney issues should skip it without doctor’s approval. Consult a pro before long – term use.
Lysimachiae Herba in the West

TCM practitioners might prescribe it for UTIs or mild liver support, often pairing it with other herbs15. It’s not a replacement for prescription drugs, but its gentle action makes it a popular natural option.
