Great for when I’m bloated, been eating unhealthily or when I’m on a weight-loss mission. It helps to cleanse the body and curb appetite. Recently discovered cold brewing it overnight helps reduce the sharp herbal taste while still getting results. If you don’t want to have to be quarantined to the toilet for days on end I recommend only having one cup in the evening. It’ll take a couple days to kick in but will only need the toilet before bed and when you wake up in the morning. The business as normal for the rest day without “accidents”. Can do this for up to 2 weeks. For fast results sip it constantly through the day refilling the same tea bag with boiling water until the water is nearly clear. NO MORE THAN 3 DAYS! Be very close to the toilet! After 3 days stop as it takes a few days to wear off. Great for those of us who need a quick fix for when we fall off the wagon. It’s not for consistent long term use. Review: Really effective - This tea is really good. I used a Feiyan tea probably 20 years ago and it always made me have diarrhea and griping pains. This tastes a bit different to how I remember it, and only bought it cos I was suffering terrible constipation/IBS. This tea has made me regular again with no griping pains, no diarrhea and my bloating is almost non existent. I’m not drinking it to lose weight, just as a bit of a gut cleanse. Perfect for my needs. I’ll only drink it when I need to. It has a sweet, earthy taste which I quite like. ## Features - Reduces Bloating ✅ - Boosts Metabolism Naturally ✅ - 100% Natural Ingredients ✅ - Caffeine-Free ✅ - Vegan Friendly ✅ - Sweet Tasting ✅ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GZQSNV6 | | ASIN | B07GZQSNV6 | | Benefits | Detox | | Best Sellers Rank | 17,408 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 104 in Detox & Cleanse Supplements | | Brand Name | FEIYAN | | Caffeine Content Description | Caffeine Free | | Container Type | Bag | | Country of Origin | China | | Country of origin | China | | Customer Reviews | 4.1 4.1 out of 5 stars (213) | | Customer reviews | 4.1 4.1 out of 5 stars (213) | | Diet Type | Vegan | | Flavour | Herbal | | Item Form | Loose Leaves, Teabags | | Item Volume | 16.9 Fluid Ounces | | Item Weight | 0.18 Kilograms | | Manufacturer | Feiyan Food CO.

If more than one person says it, I am concerned.** A: This is the only version that is allowed to sell on Amazon as far as I know. The supplier has registered the trademark of 'Feiyan' and all other versions have been removed from Amazon. We are the authorized distributor of this product and therefore can sell it. Some buyers might have got used to the taste of other versions and think everything else is fake. I can guarantee ours are original and 100% authentic. Amazon is not going to allow someone to sell fake products. Thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great detox tea *by M***O on 22 May 2024* I’ve tried and experimented with many herbal teas.

I used a Feiyan tea probably 20 years ago and it always made me have diarrhea and griping pains. This tastes a bit different to how I remember it, and only bought it cos I was suffering terrible constipation/IBS. This tea has made me regular again with no griping pains, no diarrhea and my bloating is almost non existent. I’m not drinking it to lose weight, just as a bit of a gut cleanse. Perfect for my needs.

It has a sweet, earthy taste which I quite like. ### ⭐⭐⭐⭐ Keeps you regular! *by L***N on 15 February 2026* A friend recommended this tea for my mother, who's elderly and has trouble with her bowels. One cup of this tea at night is enough to keep her regular as clockwork (almost down to the minute), and she now would not want to be without it. But two bags - oh no! Start off slowly - half a cup or a quick dunk of the tea bag – and work up to the strength that is good for your unique digestion. I cannot vouch for it's detox of slimming qualities, but for keeping you regular, it works a treat. ## Frequently Bought Together - Fei Yan Diet Tea | Authentic FeiYan | Detox & Slimming Herbal Tea | Boost Metabolism & Reduce Bloating | Weight Management Cleanse | 40 Tea Bags - Ekong Slimming Tea Oolong Version Tea Bags (Pack of 20) - Nature Therapy Ekong Chinese Slimming Tea Lose Weight Dieters (Green Tea, 2 Packs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/94970286-fei-yan-diet-tea-authentic-feiyan-detox-and-slimming-herbal](https://www.desertcart.vn/products/94970286-fei-yan-diet-tea-authentic-feiyan-detox-and-slimming-herbal) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-18*
