Say 'diet tea' out loud, and what pops into your head? For a lot of people, it’s Instagram ads, bright “detox” boxes on supermarket shelves, or promises of quick fixes that sound too good to be true. The reality, though, is very different. The habit of drinking herbal teas to support health has been around for centuries. In China, Japan, and plenty of other cultures, tea has always been more than just a drink – it’s tied to balance, digestion, and wellbeing.
One of the blends people often talk about today is Feiyan Diet Tea – sometimes called Chinese diet tea. It’s known for being lighter and more balanced than many Western slimming teas, and it’s used by people who want something to help with appetite control, bloating, and digestion. But what exactly is it, and does it really do what it says?
What Exactly Is Feiyan Diet Tea?
Feiyan is a herbal and tea-based blend with roots in Chinese traditions. It’s usually described as a natural way to support digestion and appetite, with a flavour that’s light and refreshing. There’s even a story behind the name: it’s linked to an empress in ancient China who was admired for her slim, graceful figure.
Unlike some slimming teas that rely on high caffeine levels or strong laxative herbs, Feiyan is put together with a gentler recipe. Lotus leaf, hawthorn, oolong tea, and a handful of other botanicals all make their way into the mix – each chosen because of its role in traditional wellness, whether for digestion, metabolism, or balance.
How to Prepare Fei Yan Diet Tea (Recipe)
Making Fei Yan Diet Tea is simple and refreshing:
Ingredients:
1 Fei Yan Diet Tea bag
250ml freshly boiled water
Optional: a slice of lemon 🍋, a sprig of mint 🌿, or a teaspoon of honey 🍯 for flavour
Method:
Place the teabag in your favourite cup.
Pour in freshly boiled water.

Ingredients in Detail
Here’s a look at what’s inside and why each part is there:
-
Lotus Leaf (15%) – Used in traditional Chinese medicine (TCM) when people felt heavy or bloated after eating. Early studies suggest it may also influence fat metabolism.
-
Luffa Acutangula (15%) – Also called ridge gourd. It’s not something most Western diets use, but in Asian traditions it’s linked with digestion and liver support.
-
Tangerine Peel (10%) – Aromatic and slightly bitter. In TCM, citrus peel is thought to get things moving in the digestive system and help with that sluggish, heavy feeling.
-
Astragalus Root (10%) – A well-known adaptogen that’s often used to support energy, stamina, and resilience.
-
Hawthorn Fruit (10%) – Known both in Europe and China. Often used for digestion and circulation, it adds a tart fruitiness to the tea.
-
Fiveleaf Gynostemma (10%) – Sometimes nicknamed “Southern Ginseng” and even “the herb of immortality” in China. It’s studied for antioxidant effects and possible support with cholesterol.
-
Stevia Leaf (10%) – Adds sweetness naturally, without calories, so the blend tastes pleasant without added sugar.
-
Oolong Tea (10%) – The most studied part of the formula. Oolong sits between green and black tea and has been linked to modest boosts in fat burning and metabolism.
-
Rhubarb Root (5%) – Traditionally used to help digestion. In larger amounts it can be a laxative, but here it’s just a small fraction.
-
Genmaicha (5%) – A Japanese-style mix of green tea and roasted rice. It has a nutty flavour that makes Feiyan smooth and easy to drink.
Together, these ingredients give you a tea that’s refreshing, slightly sweet, and a lot gentler than the typical slimming teas on the market.
Why People Choose Fei Yan Diet Tea
Many customers choose Fei Yan Diet Tea because it:
- Fits easily into daily routines
- Comes in convenient herbal tea bags
- Is enjoyed as part of a detoxing with tea lifestyle
- Supports mindful moments in a busy day
By combining traditional herbal wisdom with modern convenience, Fei Yan is one of the UK’s favourite herbal diet teas.
Drinking Tea Diet-Style
Most people drink Feiyan once or twice a day, usually before meals. It’s easy to prepare: just steep a teabag in hot water for three to five minutes, then sip slowly.
What makes it work isn’t just the ingredients – it’s the habit. Brewing a cup of Feiyan instead of grabbing a sugary drink or snack already puts you on the right track. That’s why many people talk about following a drinking tea diet – it’s as much about the ritual as it is about the herbs.

Does the Tea Diet Work?
So, the big question: does diet tea work?
-
On its own, it won’t give you dramatic results. You can’t drink tea and carry on with an unhealthy diet and expect miracles.
-
But as part of a healthy lifestyle, Feiyan can support appetite control, reduce bloating, and keep you hydrated – all small but important steps in weight management.
Studies on teas like green and oolong suggest modest effects on metabolism and fat oxidation. Reviews, including one from Cochrane, show green tea may help with weight maintenance when combined with diet and activity. As for the herbs like lotus leaf and hawthorn, the evidence is mostly traditional and anecdotal, but many people find them helpful.
Is the Tea Diet Safe?
People often ask, 'Is a tea diet safe?'
For most healthy adults, drinking Feiyan in moderation is fine. But here are a few points to keep in mind:
-
Herbs affect everyone differently. Some notice a difference in digestion; others don’t.
-
Don’t assume more is better. Too much can upset your stomach or send you running to the loo.
-
If you’re pregnant, breastfeeding, or managing a condition, check first with a professional.
-
Quality matters. Stick to reputable suppliers so you know you’re drinking what’s on the label.
Compared with harsher slimming teas, Feiyan is known for being gentler. That’s one reason people new to tea slimming tea routines often choose it over stronger blends.
In short: diet tea for weight loss can help, but it works best when it’s not doing all the heavy lifting by itself.
Chinese Diet Tea vs Western Slimming Teas
When you compare Feiyan to the typical slimming teas sold in Western shops, the differences are pretty clear.
Chinese diet teas like Feiyan tend to use a mix of herbs designed for balance – not just weight loss, but also digestion, energy, and general wellbeing. Ingredients like lotus leaf, hawthorn, and tangerine peel aren’t there by accident; they’re chosen to complement one another.
Western slimming teas often lean more heavily on caffeine or senna, which is basically a strong laxative. Those can give quick results, but let’s be honest: they’re not comfortable, and they’re not something you’d want to drink every day.
That’s why Feiyan is often described as a more balanced option – less of a shock to your system and more something you can stick with long term.

Where to Buy Diet Tea
Wondering where to buy diet tea like Feiyan? You’ll usually find it online from UK herbal tea retailers or specialist shops.
A few tips:
-
Look for proper labelling with the full ingredient list.
-
Read reviews to make sure other customers had good experiences.
-
Avoid suspiciously cheap versions – authentic products cost a little more but are worth it for quality and safety.
Best Tea for Weight Loss
There isn’t one single best tea for weight loss. Some people prefer green tea, others oolong, and plenty swear by pu-erh. The best one is the one you enjoy enough to drink every day.
Feiyan has become popular because it combines oolong – which has some scientific backing – with herbs traditionally linked to digestion. It’s a blend that many find easy to fit into their lifestyle.
