Cha Yi Tea

Cha Yi Tea looks like your typical green tea, but there are some extra ingredients included here. The added extras are mostly diuretics and laxatives though, which are more harmful than helpful when it comes to your general health and to weight loss. Cha Yi Tea is also very expensive. £20 for 30 teabags doesn’t represent a good deal to us. The negatives outweigh any of the positives that you would usually get with green tea.


  • Green tea is good for health and weight loss
  • Easy to take this supplement. Just add hot water and drink


  • Expensive
  • Ingredients lack clinical evidence
  • May cause side effects

Cha Yi Tea
Green tea is rich in antioxidants and as a result is becoming increasingly well known for its health benefits. Cha Yi tea is a blend of green tea and herbs that, according to the British company behind it, will help you look good and feel good, and is more palatable than many other teas on the market.

We take a look at Cha Yi tea to find out more.

Cha Yi Tea Overview

What you need to know about Cha Yi Tea

We are concerned about some of the ingredients in this tea. Just because these ingredients are natural, it does not mean they are safe. A Chinese medicinal plant may be appropriate if prescribed by a trained practitioner, but does this mean it is suitable for everyone to take?

The major problem with Cha Yi is the high number of ingredients that have a laxative and diuretic effect. This does not equate to healthy weight loss and may cause you to become dehydrated. We love green tea, and drinking more green tea will undoubtedly help weight loss and health. The trouble is that this supplement contains all these added ingredients, which do not look as healthy.

What are the side effects of Cha Yi Tea?

There are lots of laxative and diuretic ingredients included in Cha Yi Tea, so you will most likely experience side effects related to those, such as diarrhoea, dehydration, stomach cramps, etc.

How much does Cha Yi Tea cost?

One pouch of 30 teabags costs £19.99. UK postage is an additional £3.99 and international shipping is £9.00. This all seems pretty expensive.

Cha Yi Tea Key Features

Cha Yi Tea is a blend of green tea with herbs that you drink in the usual way, although without adding milk. Simply add hot water to a tea bag and you have a healthy refreshing tea that, according to the producers, will help you lose weight.

The Cha Yi blend includes Oolong green tea but it also contains Chinese mushroom Poria, Lotus leaves, Jiaogulan, Alisma Rhizome and Cassia seeds – ingredients used in Chinese medicine.

Cha Yi Tea Key Points

  • British supplement Cha Yi Ltd is based at a nature reserve in Kent
  • Green tea supplement with added ingredients
  • One month’s supply costs £32.00

There has been a lot of clinical research into green tea. The natural tea is high in antioxidants – molecules that neutralize the action of free radical cells – the dangerous abnormalities that cause disease and aging. Green tea has been investigated for its role in fighting cancer and other illnesses.

Green tea has also been investigated for weight loss and it is known to help increase the speed of the metabolism.

How to Take Cha Yi Tea

To use Cha Yi, simply add boiling water to a tea bag and drink in the usual way once or twice a day when you feel like it.

Green TeaAll tea is derived from the same plant type – Camellia Sinensis, but the basic difference between green tea and other teas is in the method of production. Unlike ordinary black tea, green tea is not fermented and, as a result, all the natural antioxidants and health giving polyphenols remain intact.

Green tea is the principle ingredient in Cha Yi. We love green tea, but we are concerned about some of the other ingredients, including Cassia seeds, known as a laxative, and Poria, known for its diuretic (urination increasing) effect.

Cha Yi Tea Concerns:

  • Customers may think that this is a simple green tea supplement, rather than a laxative
  • No ingredient quantities information
  • Lack of clinical evidence regarding efficacy and safety

Cha Yi Ltd, the company behind this tea, describe it as ideal for detoxification. However, according to medical advice, the whole principle of detoxing is flawed. It is not good for health because it can lead to dehydration and other problems. It does nothing for long-term weight loss either.

Cha Yi is a British made diet supplement. The company are based in Kent, and the business appears to be run from a nature reserve. The address is:

The Estate Office
Ranscombe Farmhouse

What does Cha Yi Tea claim to do?

According to the product information, this tea has key benefits to help you lose weight without effort:

  • Aid in blocking the absorption of fat
  • Relieve stress and anxiety
  • Lower bad cholesterol
  • Support the detoxification process
  • Raise metabolism, thus aiding weight loss
  • Soothe and ease bowel movements
  • Raise energy levels

And is:

blended to an ancient Chinese recipe that has been used for health and wellbeing for many centuries.

(All supplements that use Chinese medicinal herbs claim this!)

The flavour is important. The advertising explains,

Cha Yi Tea’s unique and ancient recipe not only helps it to far surpass the benefits of green tea alone, but actually creates a flavour that is mild and delicious, so you not only get to feel amazing but enjoy every sip along the way!

The amount you can drink each day is mentioned too,

As some of the ingredients help to support bowel movements some people find that 2 cups a day is the perfect amount for them whilst other people prefer to drink more or less.

Does Cha Yi Tea work?

It depends on what you are expecting it to do.

If you use it to support a weight loss diet and do some exercise, the green tea may help increase the metabolism slightly and in turn, we can see that this effect may help you lose weight.

The downside is that Cha Yi contains ingredients with a laxative and diuretic effect, so you may be spending more time in the bathroom than usual.

The major problem is that many of the ingredients have not been thoroughly tested.

Lotus leaf, for example, has been tested in the lab on fat cells, and at a cellular level it may affect triglyceride accumulation and lipolysis-activity in processes involved in fat metabolism. However, this has not been proven or tested in real terms on real humans, and does not come with any guidelines about dosage or potential side effects. The other ingredients are also unproven.

Cha Yi Tea Ingredients

Cha Yi is a supplement that you drink as a herbal tea. Contents of each teabag and amount quantities of individual ingredients are not specified.

  • Oolong Tea: Green tea that is available to buy in health food shops and some supermarkets. With proven health benefits because of its high levels of antioxidants, green tea has been found to promote modest weight loss because it can help increase the speed the metabolism.
    Despite the claims by Cha Yi that you do not need to increase exercise levels in order to lose weight, some clinical studies show that the best results come when combined with resistance training. Contains caffeine
  • Poria: Traditional Chinese fungus also known as Fu Ling or Chinese Root. It is sometimes used to treat memory loss, anxiety, diarrhoea but it lacks clinical evidence for the claims and requires further testing. There is a lack of information regarding safety and side effects.
  • Alisma Rhizome: Common water plant also known as Mad Dog Weed or Water Plantain. It is supposed to be effective for treating urinary tract or bladder diseases but it lacks evidence and there are concerns about possible side effects. Alisma Rhizome is toxic and just because it is a natural plant does not mean it is safe.
  • Lotus Leaf: There has been some clinical testing regarding the use of lotus leaf for weight loss. Some clinical evidence suggests it may help prevent the formation of fatty tissue. Lotus leaves contain phytochemicals and are high in antioxidants. The downside is that all clinical testing has been carried out on animals so it does not necessarily follow that the same results will be seen in humans or if it is even safe. It may cause gastrointestinal irritation and increase risk of internal bleeding.
  • Jiaogulan: Also known as Southern ginseng or Gynostemma, this plant extract is known as an adaptogen – a term for something that boosts general health, resistance and well being. There is evidence that Jiaogulan may help reduce cholesterol levels but it can cause unpleasant side effects such as diarrhoea and nausea
  • Cassia Seeds: Chinese medical herbal extract that is used for problems related to intestine, liver, large intestine and vision and is supposed to ease bowel movements. No real evidence it is effective and should be used with extreme caution. It works as a laxative and is known for gastro intestinal side effects and for causing the uterus to contract.

Cha Yi Tea Side Effects

There may be potential side effects and, although these may not be a problem for most people, it is important to be aware of risks when taking supplements.

Potential side effects include:

  • Nausea
  • Stomach cramps
  • Increased risk of internal bleeding
  • Diarrhoea
  • Increase urine output
  • Increase in menstrual bleeding
  • Dehydration
  • Contractions of uterus
  • Mild stimulant effect

Avoid if pregnant or breast-feeding. Do not take if you are trying to conceive or think you may be pregnant. One of the compounds in Jiaogulan is known for causing birth abnormalities in animals and cassia seeds can induce menstrual bleeding. Do not take if you have any health issues around the kidneys or liver. Speak to your doctor first if you are taking prescription medication especially warfarin or other blood thinking agents or anti depressants.

Cha Yi tea is not the same as ordinary green tea, so it may cause potentially dangerous side effects. There is also caffeine in green tea, so if you are sensitive to caffeine this tea will not be suitable.

Cha Yi Tea Customer Feedback

There is not much customer feedback, but from what we did find, opinion is mixed.

One customer was short and to the point giving the supplement five stars and proclaiming it “excellent”.

Another customer was happy but had issues with the construction of the tea bags,

Very good product and does what it says. But my only criticism is that some of the tea bags were not sealed properly and me waste some which I wasn’t happy about.

Another customer wrote,

Not as good as the ones in Holland and Barrett… Shop… Sorry..

Watchdog Verdict

We are not very impressed with Cha Yi. It looks to be an ordinary green tea with added benefits, but the problem is that these so-called benefits may cause side effects.

Detox teas like this do not have any advantage to losing weight because simply taking laxatives and diuretics do not lead to weight loss. In addition, the added ingredients lack clinical testing, and the long-term side effects are unknown.

Cha Yi is also expensive. Drinking ordinary green tea would be better for health and for your budget, and at £32.00 for a month’s supply this tea supplement is expensive.

We love green tea, and including more natural green tea into your routine would help you lose weight, especially if you combined it with a diet and exercise plan. However, Cha Yi is not just green tea, and we are concerned that some people may not realise that some of the ingredients in Cha Li come with potential health risks.

In our opinion, Cha Yi is not a special green tea. It is a green tea with added ingredients. You would do better to stick with plain and simple green tea and pass on Cha Yi.

We cannot add this product to our approved list, therefore we have no other option but to reject Cha Yi weight loss tea.

  1. Took this for 2 days and ended up with a flu/serious urine infection. Ie. Just one bag on each of 2 consecutive days. This happened before, though not to this extreme(i stopped taking them) so it is I believe, something to do with the constituents of this product. Maybe some people are more vulnerable to something in it.
