Crataegi Fructus, commonly known as Hawthorn Fruit or Shan Zha in Traditional Chinese Medicine (TCM), is a small, tart red fruit that’s been a cornerstone of herbal healing for centuries. Harvested from the hawthorn tree—scientifically named Crataegus pinnatifida or Crataegus monogyna—this fruit is celebrated in TCM for its ability to aid digestion, support heart health, and invigorate blood flow. Whether you’re battling bloating after a heavy meal or curious about natural ways to care for your heart, Crataegi Fructus might catch your interest. But, like any remedy, it’s not without its caveats.
In this article, we’ll explore its benefits, risks, and practical uses, blending ancient wisdom with modern science—all while keeping it easy to digest (pun intended!).
What Is Crataegi Fructus (Hawthorn Fruit)?
Crataegi Fructus is the dried, mature fruit of the hawthorn tree, a member of the rose family (Rosaceae). In TCM, it’s called Shan Zha and has been used for over a thousand years to tackle everything from indigestion to chest pain. The fruit is typically picked in autumn, dried, and transformed into teas, powders, or even candied treats like tanghulu in Chinese cuisine1.
- Scientific Names: Crataegus pinnatifida, Crataegus monogyna
- Common Names: Hawthorn Fruit, Shan Zha, Mayhaw
- TCM Role: Known for “transforming food stagnation” and promoting blood circulation2
Picture Crataegi Fructus as a tiny, natural troubleshooter for your stomach and heart. Its sour-sweet flavor comes from organic acids and flavonoids, which not only give it a zesty kick but also pack a medicinal punch. While TCM practitioners have long sworn by it, modern research is starting to back up some of these claims—making it a fascinating bridge between tradition and science.
Benefits of Crataegi Fructus in TCM
Crataegi Fructus shines in TCM for its versatility. From soothing an overstuffed belly to supporting your ticker, here’s what it brings to the table, backed by both tradition and evidence.
1. Boosts Digestion and Tackles Food Stagnation
If you’ve ever felt like a Thanksgiving feast is still sitting in your stomach hours later, Crataegi Fructus might be your new best friend. In TCM, it’s a go-to for “food stagnation”—that heavy, bloated feeling after eating too much, especially greasy or meaty dishes.
- How It Works: Packed with organic acids and enzymes, it revs up your digestive juices to break down food faster. Think of it as a gentle nudge to your stomach to get back to work3.
- Evidence: A study in Molecular Biology Reports suggests it may help with non-alcoholic fatty liver disease (NAFLD), often tied to sluggish fat metabolism.
- Traditional Take: Ancient texts like Ben Cao Gang Mu praise it for dissolving meat accumulation and easing bloating4.
2. Supports Heart Health
In TCM, Crataegi Fructus is said to “invigorate blood,” helping with chest tightness or irregular heartbeats5. Modern science agrees it’s got some heart-friendly chops.
- How It Works: Its flavonoids and polyphenols act as antioxidants, protecting your heart and improving blood flow. It’s like a mini spa day for your cardiovascular system.
- Evidence: A randomized trial found hawthorn lowered blood pressure in diabetic patients, while another study showed benefits for mild heart failure6.
- Fun Fact: In China, it’s sometimes paired with other herbs to soothe heart-related discomfort—less “pounding chest,” more “calm vibes.7”
3. May Lower Cholesterol
Struggling with high cholesterol? Crataegi Fructus might lend a hand by scrubbing your arteries clean—figuratively, of course.
- How It Works: Its triterpenic acids and polyphenols could reduce LDL (“bad”) cholesterol while boosting HDL (“good”) cholesterol.
- Evidence: A meta-analysis confirmed TCM formulas with Crataegi Fructus effectively cut blood lipids in hyperlipidemia patients.
- Traditional Wisdom: TCM sees it as a way to clear “stagnant blood,” which aligns with its lipid-lowering potential8.
4. Bonus Benefits
Crataegi Fructus isn’t a one-trick pony. It’s also been used for:
- Menstrual Relief: Its blood-moving properties may ease cramps or irregular cycles9.
- Postpartum Recovery: Helps new moms by promoting circulation, per TCM10.
- Antioxidant Power: Fights inflammation and cell damage, thanks to its polyphenol content11.
While these uses need more research, they highlight why Shan Zha has stuck around for centuries.
Summary: Crataegi Fructus, or Shan Zha, is highly versatile in TCM. It aids digestion, supports heart health, may lower cholesterol, and has other potential benefits like menstrual relief. Both tradition and science back its uses.
Risks and Precautions
Crataegi Fructus isn’t all sunshine and roses—it’s got some thorns to watch out for. Here’s what to keep in mind:
1. Drug Interactions
Mixing Crataegi Fructus with certain meds can be tricky, especially for heart or blood conditions12.
- Blood Pressure Drugs: It might amplify their effects, dropping your pressure too low.
- Blood Thinners: Could increase bleeding risk by enhancing circulation.
- Advice: Check with your doctor if you’re on prescriptions—better safe than sorry!
2. Stomach Upset
Ironically, the fruit that helps digestion can upset it if overdone13.
- Symptoms: Too much raw Shan Zha might cause acid reflux, stomach pain, or diarrhea.
- Fix: Stick to cooked forms (like tea) and start small.
3. Who Should Skip It?
Not everyone’s a good match for Crataegi Fructus14:
- Pregnant Women: It may stimulate the uterus, risking complications—steer clear unless your doc says otherwise.
- Spleen Deficiency (TCM Term): If your digestion’s already weak, it might make things worse.
- Kids: Too much sugar-laden hawthorn candy could harm teeth or appetite.
4. Rare Allergies
Though uncommon, some folks might get itchy or rashy. Stop using it and see a doctor if that happens15.
Summary: Crataegi Fructus has potential issues. It can interact with certain drugs, cause stomach upset if overused, and isn’t suitable for pregnant women, those with spleen deficiency or kids. Rare allergies are also possible.
How to Use Crataegi Fructus
Ready to give Shan Zha a whirl? Here’s how to enjoy it safely and effectively:
1. Tea from Dried Slices
- How: Steep 10-15 grams of dried Crataegi Fructus in hot water for 10-15 minutes.
- When: Sip 1-2 cups daily, post-meal for digestion.
- Twist: Add honey or ginger for flavor and extra gut support.
2. Powder or Capsules
- How: Follow package directions—usually 500-1000 mg daily, split into doses.
- Why: Perfect for busy bees who skip the brewing.
3. In the Kitchen
- How: Try it in candied form (tanghulu) or as a sauce ingredient in Chinese dishes.
- Caveat: These can be sugary, so don’t overdo it.
4. Tinctures
- How: A few drops in water, per the label—great for a potent hit.
- Note: Best with professional guidance due to concentration.
Pro Tip: Avoid eating it raw or on an empty stomach—its acids can be harsh on an empty belly.
Summary: Crataegi Fructus, or Shan Zha, can be used in various ways. Make tea with dried slices, take powder/capsules, use in the kitchen, or try tinctures. Remember to avoid raw consumption and on an empty stomach.

The Bottom Line
Crataegi Fructus, or Hawthorn Fruit, is a gem in TCM, offering a natural boost for digestion, heart health, and more. Its blend of tradition—think ancient healers scribbling in Ben Cao Gang Mu—and modern research makes it a standout. But it’s not a free-for-all. Watch for drug interactions, start slow, and talk to your doctor, especially if you’re pregnant or medicated.
Whether you’re brewing a cozy tea or nibbling a candied slice, Crataegi Fructus brings a tangy twist to wellness—just don’t eat it straight from the tree unless you’re ready for a pucker!
