Houttuynia Yu Xing Cao Fishy Smelling Herb Cut 1 lb – Nuherbs
A traditional Chinese herb known for its naturally strong aroma, cooling nature, and long history of use in herbal wellness practices.
Quick Answer
Yu Xing Cao (Houttuynia cordata) is a traditional Chinese herb commonly used in herbal tea and decoction preparations. In Traditional Chinese Medicine (TCM), it is traditionally associated with “cooling” and “clearing” properties and is often selected seasonally for respiratory and throat wellness support. The herb has a naturally pungent, fishy aroma that many experienced herbal users recognize immediately.
What Is Yu Xing Cao?
Yu Xing Cao is the traditional Chinese name for Houttuynia cordata, a plant used for generations throughout Asia. It is commonly recognized by its extremely distinctive aroma — often described as earthy, pungent, or “fishy.” Interestingly, experienced herbal users often see this strong aroma as a sign of freshness and potency rather than a flaw.
In Traditional Chinese Medicine, Yu Xing Cao is traditionally categorized among herbs that “clear heat and resolve toxicity.” Modern discussions surrounding the herb often focus on its naturally occurring plant compounds including flavonoids and volatile oils.

Why Does Yu Xing Cao Smell Fishy?
This is one of the most searched questions online about Yu Xing Cao.
The naturally occurring aromatic oils inside the plant are responsible for its strong smell. Some people compare it to cilantro, while others compare it to damp earth, old roots, or fish. Herbalists familiar with traditional herbs often associate stronger aroma with fresher, higher-quality material.
Ironically, if Yu Xing Cao has almost no smell at all, it may actually indicate:
- Old inventory
- Poor storage conditions
- Loss of aromatic oils
- Low freshness

How To Prepare Yu Xing Cao Tea
The “best” method depends on the form you bought and your routine. Use the simplest method you’ll actually stick with.
Option 1
: Tea / Infusion (best for cut herb)
- Starter ratio: 1 tablespoon dried herb per 1 cup hot water
- Steep: 8–12 minutes, covered
- Tip: covering the cup keeps the aromatic fraction from drifting off into your kitchen air
Option 2: Gentle simmer (stronger extraction)
- Starter ratio: 1–2 tablespoons herb per 2 cups water
- Simmer: 15–20 minutes on low heat
- Use: drink warm or refrigerate up to 3 days

Option 3: Powder (capsules or blending)
If you purchased powder, capsules are the cleanest route when taste is a deal-breaker. For powder-specific instructions: click here for our detailed powdered herb guide .
Best practice: Start modestly, track your routine, and adjust one variable at a time (amount, steep time, or frequency). Consistency beats guessing.
Helpful Brewing Tip
Cover your tea while steeping. Aromatic herbs naturally release volatile oils into the air. Keeping the cup covered helps preserve the herbal aroma and overall brewing experience.
How To Make Yu Xing Cao Taste Better
- Add raw honey after brewing
- Combine with Chen Pi (aged citrus peel)
- Blend with mild herbs
- Drink warm instead of overly hot
- Use capsules if taste is difficult
