You’ve probably heard the rumors or seen the dusty bags in the back of a traditional apothecary. It goes by a few names, but most folks just call it the bitter tea of General Zhao. It isn't your average Earl Grey or a soothing chamomile meant to tuck you into bed. No. This stuff is legendary for a reason, and that reason is usually the face people make after the first sip. It’s a physical experience.
If you’re looking for a sweet beverage, turn back now. This tea—historically linked to the TCM (Traditional Chinese Medicine) preparation known as Kudingcha or specifically the "General’s" formulation—is a punch to the palate. But why do people keep drinking it? Honestly, it’s because it works for what it’s meant to do, even if it feels like you're drinking liquid charcoal and lawn clippings.
What is the Bitter Tea of General Zhao exactly?
Let’s get the botany out of the way first. When people talk about General Zhao’s bitter tea, they are almost always referring to a specific type of Kuding tea (Ilex kaushue or Ligustrum robustum). It’s not actually a "tea" in the way Darjeeling is. It’s made from the leaves of a holly tree. The leaves are typically twisted into long, thin spikes that look like dark green nails or cigars.
History is a bit fuzzy on which "General Zhao" specifically popularized it, though folklore often points toward the Song Dynasty or the later Qing era. Soldiers were notoriously prone to "internal heat" (inflammation, fevers, and digestive sluggishness) while on the march. Legend says a General Zhao discovered that this specific bitter brew could snap a soldier out of a fever faster than almost anything else in the camp. It became a staple for survival. It wasn't about the flavor profile; it was about staying alive and keeping the "fire" out of the blood.
The Science of the "Ouch"
Why is it so bitter? It’s the saponins and polyphenols. Specifically, Ilex kudingcha contains a massive concentration of ursolic acid and other glycosides. These compounds are bioactive powerhouses. In a 2013 study published in the Journal of Agricultural and Food Chemistry, researchers found that the polyphenols in Kuding tea were significantly effective at lowering blood lipids.
It’s not just "ancient wisdom." There’s real chemistry here.
Most people drink it today for "de-toxing," though that's a loaded word. In TCM terms, it’s about clearing Heat and Wind-Heat. If you’ve got a sore throat that feels like you swallowed a cactus, or if your eyes are bloodshot and itchy from allergies, this tea is designed to "cool" that internal inflammation. It’s basically a biological fire extinguisher.

How to brew it without ruining your day
If you throw five spikes of the bitter tea of General Zhao into a mug and let it sit for ten minutes, you will not be able to drink it. You just won't. I’ve seen people try. They usually end up pouring it down the sink.
The Golden Rule: One is enough.
Seriously. For a standard 8-ounce cup, you only need one single "needle" or twisted leaf.
- Use water that is just off the boil—around 175°F to 190°F. Boiling water scorches the leaf and releases the bitterness too aggressively.
- Flash brew it. Don't leave it in there. Dunk the leaf for maybe 30 to 45 seconds.
- The water should turn a very pale, translucent yellow-green. If it turns dark green, you’ve gone too far.
The weirdest part? The "Huigan." This is a Chinese term for the "returning sweetness." After the initial shock of bitterness passes, a high-quality General Zhao tea leaves a lingering, cool sweetness at the back of the throat. It’s a bizarre sensory trick. If you don't get that sweetness, you either have bad tea or you over-steeped it.
Why modern health nerds are obsessed
We live in an era of "glucose spikes" and "metabolic syndrome." This is where the bitter tea of General Zhao actually finds its modern niche. Recent clinical observations have suggested that the bitter compounds help sensitize the body to insulin.
Basically, it helps your body manage sugar better.

In 2021, research into Ligustrum robustum (one of the plants used for this tea) showed potential in neuroprotective qualities. It’s not a magic pill, obviously. But as a functional food, it’s hard to beat. People who struggle with high blood pressure often swap their morning coffee for a weak infusion of this tea. They claim it keeps the "pressure" down without the caffeine jitters.
Note: It does contain caffeine, but the levels are generally lower than a heavy Black Assam or a double espresso. It’s a different kind of energy—more like a focused clarity than a frantic buzz.
The Common Misconceptions
People think "bitter" always means "liver detox." That’s a bit of a stretch. While the bitter tea of General Zhao does help with bile production (which aids digestion), it isn't a magical eraser for a weekend of heavy drinking.
Another mistake? Thinking you can sweeten it.
Do not add honey. Do not add sugar. Honestly, it makes it taste worse. The sweetness of the sugar clashes with the chemical bitterness of the saponins in a way that is genuinely revolting. It’s like putting syrup on kale. Just take it as it is. It’s a medicinal experience, not a dessert.
Who should avoid it?
Because this tea is "extremely cold" in the TCM energetic framework, it’s not for everyone.

- Pregnant women: Just don't. It's too stimulatory for the digestive system and has "descending" energy.
- The "Cold" types: If you’re always freezing, have a pale tongue, or suffer from frequent diarrhea, this tea will likely make you feel worse. You’re already "cold"; you don’t need a liquid iceberg.
- Anemic individuals: Some studies suggest high polyphenol intake can inhibit iron absorption if taken right with meals.
Finding the real deal
You want the stuff that looks like tiny, dark umbrellas or spears. Avoid the "tea bags" where the leaves are crushed into dust. When the leaf is crushed, the surface area increases so much that the bitterness becomes uncontrollable. You want the whole leaf.
Check the origin. The best bitter tea of General Zhao typically comes from the mountainous regions of Guangxi or Hainan in China. The high altitude and mist keep the leaves tender but potent.
Actionable Steps for the Brave
If you’re ready to try the bitter tea of General Zhao, don’t just dive in headfirst. Start slow.
1. The "Entry Level" Infusion
Instead of drinking a full cup, drop one leaf into a large liter-sized carafe of room temperature water. Let it cold brew for two hours. This extracts the medicinal properties without the overwhelming "General's punch" to the face. It’s much more manageable.
2. Watch the Clock
Drink it in the afternoon. Because of its cooling nature, drinking it on an empty stomach first thing in the morning can be a bit harsh on the gastric lining. 1:00 PM to 3:00 PM is the sweet spot for clearing that midday brain fog.
3. Pair it with Heavy Foods
If you’ve just had a greasy, heavy meal (think fried chicken or a thick burger), that’s when the bitter tea shines. It cuts through the fat and helps the gallbladder do its job. It’s the ultimate digestive aid for those days you overindulged.
4. Quality Test
Place one leaf in a glass of hot water. If the leaf unfurls and stays relatively intact, it’s high quality. If it falls apart into mush, it’s old stock. Freshness matters even for bitter teas.
This isn't just a drink; it's a test of resolve. But for those who can handle the General’s brew, the clarity and "cooling" effect are unlike anything else in the tea world. Just remember: one leaf, short steep, and don't say I didn't warn you about the taste.
