How Much Caffeine in Tea and Coffee
Caffeine Levels in your Morning Cuppa
Did you know that an estimated 60 plants naturally contain caffeine? This includes nuts from the Kola tree - famously used to create soft drinks. There is also, of course, the Theobroma cacao tree, which produces the beans utilised in chocolate-making.
Most noteworthy, however, is caffeine in Coffee - the product of the Coffea plant. A close second is that of caffeine in Tea, which comes from the Camellia sinensis plant. This blog will focus, in particular, on the facts, figures, history and health benefits of caffeine in Tea and Coffee.

What is Caffeine?
People have known about Tea for some 5,000 years. Coffee, meanwhile, has played a role in human history for at least a few hundred years. Despite this, knowledge about caffeine in Tea and Coffee only dates back to the 19th century.
It was a German scientist named Friedrich Ferdinand Runge who discovered caffeine in the 1820s. The term itself is a combination of the German word for “kaffee” and the French word “café”. But what, exactly is it - and how does it work?
Caffeine is a naturally occurring stimulant found in leaves and seeds. Once consumed, it is quickly absorbed into the bloodstream before travelling to the liver. There, it is broken down and passed on to numerous other organs in the body, namely the brain.
Its effect on the brain, in particular, is the primary reason why so many people consume caffeinated products. This is because it blocks adenosine, a neurotransmitter that relaxes the mind. In essence, by blocking large quantities of adenosine, caffeine has the opposite effect. It stimulates while making you feel more energised and less sleepy.
Additionally, caffeine can increase blood adrenaline levels and even heighten brain activity of neurotransmitters such as dopamine and norepinephrine. Most will know already that dopamine running through the system plays a significant role in, well, feeling good!
In the wild, caffeine works in an entirely different way. Instead of acting as a stimulant, it becomes a natural pesticide in plants, thus protecting them against harmful insects. It is also artificially created and added to products such as diet aids and cold/flu remedies.
For most of us, caffeine in Tea and Coffee offers a much-needed boost first thing in the morning. In other words, it’s the motivation to get out of bed and start the day the right way!
Caffeine in Coffee
Many people consider Coffee THE brew of choice for getting a substantial caffeine fix. However, the word “brew” is the essential term to use. Confused? Allow us to explain.
The quantity of caffeine in Coffee, specifically in dry form, is less than that in an equal weight of Tea. This means that, before brewing, there is, technically speaking, more caffeine in Tea than there is in Coffee.
As baffling as it might sound, it’s true. However, this ultimately changes due to how many cups of Tea or Coffee you can get from a unit quantity.
Still confused? That’s okay. Basically, you can get more cuppas from a unit quantity of Tea leaves than from an equal quantity of Coffee. This means that caffeine content in Tea ‘spreads out’ while the caffeine in Coffee is more concentrated.
Regardless of the complicated ins and outs, Coffee is, undoubtedly, the most popular caffeinated drink around. We have approximately 70 types of Coffee worth trying and, indeed, enjoying! Many of these contain significant amounts of this stimulating chemical compound (but not all of them!).
Caffeine in Tea
The word “Tea” has, in recent years, become somewhat of an umbrella term encompassing a wide range of infusions. The likes of Peppermint, Camomile and Hibiscus, for example, have all gone by this name.
However, it’s important to note that almost all of these beverages are NOT “Teas” in the conventional sense. Only those that have come from the Camellia sinensis plant meet the ‘requirements’.
The four primary Types of Tea to originate from this plant are Black, Green, White and Oolong Tea. But what makes one different from another? It’s all about the processing of the leaf. In a nutshell, White Tea is the least processed kind, followed by Green, then Oolong, then Black. Each one has something unique to offer - which includes Tea caffeine content levels!
Contrary to popular belief, most Teas contain a similar amount of caffeine until the water reaches the leaf. Most will know, however, that Black Tea caffeine is ultimately more significant than Green Tea caffeine. So what changes? A study conducted at the University of Florida suggests that it’s all about the time you take brewing a cuppa.
Researchers discovered that one-minute brew times yielded 14 milligrams of caffeine for Black Tea and 12 milligrams for Green Tea. Many would agree that this is a minimal difference in terms of caffeine levels. However, a three-minute brewing time saw the former beverage yield 27 milligrams and the latter 22 milligrams. And so the gap widens.
Finally, the study concluded that a five-minute brewing time (which isn’t recommended for Green Tea!) had the biggest difference. Here, the results determined that Black Tea contained 61 milligrams while Green Tea had no more than 41 milligrams. So, in other words, be sure to brew for longer if you’re looking for an extra caffeinated kick!
Caffeine Content in Tea and Coffee
But what does this all mean? We’ve learnt that brewing matters, and that before this takes place, Tea has more caffeine than Coffee. However, unless you’re a scientist, this is all of little consequence to your daily life. The question begs: how much caffeine in Coffee and Tea is there... ultimately?
Below is a table showing the average caffeine levels in your morning cuppa. To the left, you’ll find information on Coffee caffeine content, while to the right you’ll see the same about Tea.
Amount of Caffeine in Tea and Coffee
|Filter Coffee (8 oz cup)||95-200 mg|
|Latte (8 oz cup)||75 mg|
|Cappuccino (8 oz cup)||75-180 mg|
|Flat White (8 oz cup)||75-150 mg|
|Black Tea||40 mg|
|Oolong Tea||35-37 mg|
|Green Tea||30 mg|
|White Tea||15 mg|
When it comes to Tea, in particular, there are a couple of more variables to think about. Matcha Tea, for example, contains more caffeine than so-called ‘regular’ Green.
This is because Matcha uses the entire leaf while its ‘regular’ counterpart only uses parts. Furthermore, unlike humans, age matters. As a rule of thumb, the older the leaf, the more caffeine.
In the world of Coffee, meanwhile, caffeine levels can also vary significantly depending on a couple of factors. Nevertheless, the type of Coffee bean used (i.e. Arabica or Robusta) is, undoubtedly, the most influential aspect to consider. This is due to the fact that Arabica (despite being more popular) has 1.5% less caffeine than Robusta.
What about Coffee roasts? Contrary to popular belief, this has less of an impact on Coffee caffeine content than many might think. Some say that lighter roasts contain more caffeine than darker roasts. This might be true on occasions, but its effect is minimal at best.
How is Tea and Coffee Decaffeinated?
It’s fair to say that caffeine has the admiration of early-morning office workers and late-night waiters everywhere. Without it, some might struggle to function day after day after day. Yet not everyone likes the feeling of caffeine effects.
Others might even want to steer clear of it due to medical conditions. Enter Decaf Tea and Coffee - beverages that have, as their names suggest, undergone decaffeination.
Decaffeination is the process of removing caffeine from products such as soft drinks, chocolate and, of course, Tea and Coffee. Before this takes place, EVERY beverage to contain one of these ingredients has caffeine within it.
In fact, contrary to popular belief, even DECAF products contain a trace amount of this stimulant. In other words, NO caffeine-filled product can be 100% decaffeinated.
Depending on the efficiency of the decaffeination process, products can have about 94-98% of caffeine removed. Indeed, the best options will have no more than 5-10 milligrams remaining. This, in the whole scheme of things, is very little!
Process used for Decaffeination
A few decades after the discovery of caffeine, Ludwig Roselius, another German, found a way to remove it from products. By using benzene, a potentially toxic hydrocarbon, Roselius was able to extract caffeine molecules from pre-moistened green Coffee beans.
The good news is that, since 1905, the industry has experimented with other, safer methods of decaffeination. Although not all of them are perfect, they’re certainly better than using dangerous hydrocarbons! Below are the four primary methods considered the best:
Methylene chloride Process
This, unfortunately, is one of the most widespread means of decaffeination. It uses the chemical methylene chloride as a solvent to extract the caffeine from raw materials, including Tea and Coffee.
Although efficient, this method is, nowadays, considered unsafe. Indeed, while it can remove 96-97% of the caffeine, it also comes with severe health warnings. You’ll be pleased to know, then, that The Kent and Sussex Tea and Coffee Company steer well clear of it!
Ethyl Acetate Process
This is a chemical found naturally in many fruits which, similar to methylene chloride, can be used as a solvent. However, despite its so-called ‘organic’ name tag, Ethyl Acetate (again much like methylene chloride) can cause health complications.
This process nevertheless removes 96-97% of caffeine content. That said, with the welfare of our customers in mind, we as a company avoid this method, too.
Carbon Dioxide Process
Here, we’re heading into much, much safer territory. In fact, the CO2 process is, according to research, the safest AND most efficient method of decaffeination. It works by using pressurised liquid carbon dioxide to extract the small caffeine molecules.
So, what makes it different from the rest? Why, exactly, is it safe and efficient? Well, put simply, it’s safe because it avoids the use of solvents and instead opts for natural CO2.
Meanwhile, efficiency comes into the equation due to the fact that it leaves the larger flavour molecules almost entirely intact. Basically, low caffeine levels (the removal of 96-98%, to be specific!) and great taste are all but guaranteed.
Just for the record, this term doesn’t refer to water specifically from Switzerland. Rather, it’s a process first invented in this country! What it does is use hot water to extract both the flavour and caffeine molecules.
These molecules then pass through a carbon filter, resulting in the larger flavour molecules being retained. Finally, the water is returned to the Coffee, thus enabling the beans to once again soak up their flavour. This ultimately brings about the removal of 94-96% of the caffeine content.
Does Caffeine Free Tea or Coffee Exist?
Is there such a thing as an entirely caffeine free Tea or Coffee? Yes and no. As mentioned previously, there is no method of decaffeination that can remove 100% of all caffeine content. Likewise, no ‘real’ type of Coffee or Tea is devoid of the substance.
So where does the “yes” come into the equation? With Herbal Tea and Fruit Tisanes, of course! Despite not technically being “Teas”, these beverages still have much to offer.
From Camomile to Peppermint; Rooibos Tea to Lemongrass, Peach or Turkish Apple Tea, the possibilities are almost endless. Perhaps best of all, none of these has caffeine.
Does that mean that all Herbal and Fruit Tisanes are caffeine-free? Not quite. There is, indeed, one noteworthy exception to this rule: Yerba Mate. This Tea (pronounced “Yer-bah-mah-tay”) is the product of a plant (Ilex Paraguariensis) that grows predominantly in the South American rainforest.
It belongs to the Holy family, standing at 6-8 metres tall while producing evergreen leaves, small berries and greenish-white flowers. Many say that it combines the energy boost of Coffee, the benefits of Tea and the endorphin buzz of chocolate.
This is in part due to its brewed leaves containing around 85 mg of caffeine per 8 oz cup. (That’s the equivalent of roughly two cups of regular Black Tea).
Daily Recommended Caffeine Intake
How much is too much caffeine? This very much depends on the individual and their circumstances. Evidence indicates that consuming up to 400 milligrams of caffeine daily is safe for most healthy adults. This is about four cups of brewed filtered Coffee or ten cups of Black Tea.
It’s vital to note the words “healthy” and “adult” in this daily caffeine intake recommendation as it has far-reaching consequences. For example, those who’re caffeine sensitive, although not exactly ‘unhealthy’, might want to limit their intake.
The same applies to children and adolescents. Furthermore, pregnant women and breastfeeding mothers should reduce their caffeine consumption (more on this later).
What has More Caffeine Tea or Coffee?
Believe it or not – it depends on your perspective! The quantity of caffeine in coffee - specifically in dry form - is less than the quantity of caffeine in an equal weight of tea leaves.
However, as a result of getting more cups of tea from a unit quantity of black tea than from an equal quantity of ground coffee beans - when brewed. The quantity per cup of tea is less than that of an equal cup of coffee.
On this basis, the average cup of black tea contains approximately 40 milligrams, while an average cup of instant coffee will likely contain upwards of 105 milligrams! So, do not be fooled by sensationalist reporting from many media outlets – they do not give you all of the fact, we do!
How Long Does Caffeine Last in Your System?
Similar to the food we eat, caffeine in Tea and Coffee must metabolise in our system. This chemical compound makes light work of passing through epithelial tissue, meaning it reaches the bloodstream in no time at all.
Following this, absorption takes about 45 minutes, with its effects lasting anywhere from four to six hours.
Here we have yet another example of variables, however. This refers to the fact that not everyone metabolises caffeine at the same rate. Age, medical conditions and drug interactions can all have an influence on how long it takes to feel caffeine effects.
Is caffeine bad for you? On the contrary, preliminary evidence has indicated that there might be health benefits to consuming it! This is perhaps most interesting because, only a few years ago, The World Health Organisation (WHO) considered it a carcinogen.
Now, however, WHO suggests that it’s quite the opposite. In fact, research shows that caffeine may reduce the risk of liver cancer by up to 40%.
But that’s not all. One study out of John Hopkins University in Baltimore, USA, showed that a 200mg caffeine pill helped boost memory consolidation. There is even the possibility that some day, caffeine could help those living with dementia and Alzheimer’s disease.
Additionally, there is the potential that caffeine can reduce the risk of type-2 diabetes. This is according to several massive studies of more than 30,000 participants. If proven outright, many lives could change for the better in part thanks to caffeine in Tea and Coffee.
Caffeine Weight Loss
There is, of course, no fix-all solution to maintaining a healthy weight. However, caffeine in Coffee and Tea might help. This is according to research out of Germany, which established that 2-4 cups of Coffee daily could support weight loss.
Another study noted that caffeine stimulates brown fat cells, thus causing them to burn more calories. This increases overall metabolic rate.
Caffeine can support periods of exercise, too. Indeed, evidence published in the Journal of Applied Physiology looks particularly promising. Scientists instructed participant athletes to split themselves into two groups. The first group consumed both caffeine and carbs after strenuous exercise, while the second group ingested only carbs.
The results determined that the first group had 66% more glycogen in their muscles than the second group post-workout. But why, exactly, is this so significant? Glycogen is the fuel used by muscles to function. As such, increasing glycogen levels after a hard workout helps athletes to recover faster and perform better next time around.
Caffeine for Hair Health
We often experience many problems while getting older. Sadly, it’s a fact of life. But what if we can slow it down - if only a little bit? Enter caffeine for hair health!
Caffeine shampoo has become a particularly popular product in recent years. This, it seems, is with good reason, with studies suggesting that it can help balding men and women regrow hair.
Arguably most noteworthy is research published in the International Journal of Dermatology. It saw experts take biopsies from the scalps of 14 men in the early stages of hair loss.
These hair follicles were then exposed to solutions containing different levels of caffeine. At the same time, some follicles had Dihydrotestosterone (DHT) introduced to them, the hormone responsible for hair loss. After eight days, all hair follicles, including those exposed to DHT, showed growth.
Caffeine and Eye Health
There are a couple of ways that caffeine in Coffee might help with eye health. First off, it could reduce the risk of involuntary eye spasm - also known as primary late onset blepharospasm. This is according to evidence provided by BMJ Specialty Journals, suggesting that two cuppas daily is all you need!
Furthermore, and perhaps more importantly, caffeine may prove useful in the prevention of cataract formation. Although treatable through surgery, a new study conducted by the University of Maryland School of Medicine may prove this unnecessary. (That said, please note that The Kent and Sussex Tea and Coffee Company do NOT endorse it per se!).
Scientists used two groups of rats fed on a diet high in galactose. This is a type of monosaccharide sugar that can lead to cataracts forming in the eyes.
Following this, one group of rats received eye drops containing caffeine, while the other group had a placebo. Ultimately, the animals given caffeine had significantly reduced cataract formation compared to the placebo group
Caffeine for Blood Pressure?
If you experience low blood pressure, there is an argument that caffeine might be of some benefit. However, it’s equally fair to say that this is far from the consensus.
In fact, most doctors advise against vast quantities of caffeinated beverages before having your blood pressure checked. This is based on the notion that caffeine raises blood pressure and thus interferes with accurate measurements.
Is that the entire truth, though? A group of scientists in Switzerland and the United States think not! They asked 15 volunteers, none of whom had high blood pressure, to drink a triple espresso.
Before and after this happened, the researchers monitored the blood pressure, heart rate and sympathetic nervous system of each participant. It turns out that a triple espresso causes quite a jolt, but does not necessarily influence blood pressure readings.
It’s essential to note, however, that this is but one study against a mass of evidence on the contrary. For this reason, we strongly urge you to seek medical consultation before consuming caffeine while experiencing high blood pressure.
Caffeine Side Effects
The potential of experiencing high blood pressure isn’t the only possible side effect of caffeine. Most famously, overconsumption can lead to jitteriness and sleeplessness. This is most common in those who’re considered particularly sensitive to the Effects of Caffeine.
Unfortunately, this stimulant might have a negative impact on your health in a few other ways, too. It can, among other caffeine effects, bring about anxiety, digestive issues, rapid heart rate, addiction and even, ironically, fatigue. For these reasons, it’s vital to monitor your caffeine intake every day.
Indeed, benefits and side effects alike should be talked about with your doctor or health professional. After all, they will, undoubtedly, know best.
Caffeine is, technically speaking, a drug. As such, excessive use of it can lead to caffeine addiction. This, in turn, can cause several symptoms associated with stimulation of the brain and nervous system. The most common such effects are:
- Poor sleeping patterns
- Muscle twitching
- Disrupted flow of thoughts and speech
- Flushed face
- Increased heart rate
- Digestive complaints
- Excessive urination
Those who give up ‘cold turkey’ might also suffer from caffeine withdrawal symptoms. This, of course, happens due to caffeine addiction. Typically, these withdrawal symptoms, most notably headaches, arises after 12-24 hours of not consuming the substance.
Can you have a caffeine overdose? Yes. In fact, in the worst (though rarest) cases, it can even be life-threatening. As mentioned previously, evidence indicates that consuming up to 400 milligrams of caffeine daily is safe for most healthy adults. Adolescents, meanwhile, should have no more than 100 mg.
In both of these examples, any more than the daily recommended amount increases the risk of experiencing a caffeine overdose. This can lead to major health problems such as irregular heartbeat and seizures. Others symptoms include:
- Excessive thirst
- Hormone imbalances
If you believe you’re experiencing a caffeine overdose, it’s vital that you go to the hospital immediately. There, you might receive activated charcoal, a universal remedy for many kinds of drug overdoses. This will prevent the caffeine from reaching your gastrointestinal tract.
If, however, it has already entered your gastrointestinal tract, you might instead be offered a laxative or even gastric lavage. Whatever happens, your doctor will know the best method to help.
Does Caffeine Cause Headaches
Some people might suffer from symptoms associated with a caffeine overdose despite not exceeding the daily recommended intake. If you fit this description, you might, unfortunately, have a non-allergic caffeine intolerance. Be sure to talk to a doctor or health professional if this is the case.
Intolerance to caffeine is considerably different from an allergy, which is much rarer. A caffeine allergy is also far more severe, with symptoms including:
- Hives (a rash made up of numerous red bumps)
- Swelling/itching around the lips and tongue
- Trouble breathing/speaking
- Nausea/vomiting/abdominal pain
- Rapid heartbeat
In the most extreme cases, those living with an allergy who come into contact with caffeine might experience anaphylactic shock. This, we hasten to add, is very unlikely, but it’s vital you go to the hospital should this occur.
Caffeine Pregnancy and Breast Feeding
Those who’re pregnant, in particular, should exercise caution when consuming Teas and Coffees that contain standard quantities of caffeine. NHS Choices recommends that one limits caffeine intake to no more than 200 milligrams per day, which is the equivalent to two cups of Coffee.
Should one exceed the recommended limit, this does not necessarily mean that one is being unsafe; rather that one should, perhaps, not make a habit of exceeding the recommended limit on a daily basis. Any concerns should always be taken up with a midwife, doctor or another healthcare professional.
What about breastfeeding mums? For the most, the above advice from NHS Choices applies here, too. Be mindful, however, that when caffeine enters your bloodstream, a small amount can pass to your baby through breast milk. Most young children aren’t affected by this, but some, like adults, might be sensitive.
Caffeine withdrawal symptoms are often experienced by those who consume large quantities of caffeine on a frequent basis. If the body becomes caffeine dependent, then eliminating it from one’s diet can cause these withdrawal symptoms. Typically arise after 12-24 hours of not consuming the substance.
Headaches are among the most common symptoms of caffeine withdrawal. This occurs because caffeine consumption causes blood vessels to narrow, so when it is not present in the system. The blood vessels again open up while increasing blood flow to the brain. The sudden change in blood flow can cause these often uncomfortable headaches. It can vary in length and severity as the brain adapts to the increase in blood.
Paradoxically, other symptoms of caffeine withdrawal include many of those associated with caffeine overconsumption, such as fatigue and anxiety. Additionally, some may experience difficulty concentrating, irritability and low energy.

Common Caffeine FAQ's
If you find yourself with still more questions about caffeine in Tea and Coffee, you may find the answers below. Discover whether caffeine is bad for you; if it’s a drug; and how long it takes to kick in.
Realise its full potential as a diuretic, as well as where, exactly, it comes from. This is, of course, to name but a few of the queries we cover. So, without further ado, let’s get started.
It’s true that caffeine has numerous benefits, as mentioned in the article above.
This includes (but is not limited to) weight loss, as well as improved hair and eye health. Nevertheless, it would be wrong for us to gloss over its less-than-desirable qualities.
Although we’ve talked about a few already, it’s important that we really hit this home. Caffeine, under some circumstances, can, unfortunately, be bad for you.
It very much depends on your personal circumstances. While some will find themselves consuming caffeine without any side effects, others will be particularly susceptible to them.
Pregnant women and caffeine-sensitive individuals, first and foremost, should monitor their intake. However, you don’t have to have any underlying conditions to experience issues with caffeine.
The bottom line is you should be wary of your consumption no matter your position. If in doubt, talk to a doctor or another medical professional - especially if you experience any side effects.
For the most part, the term “espresso” (“ess-press-oh”) refers to a method of making Coffee rather than a specific type.
However, many associate it with a full-flavoured, concentrated form of Coffee served in so-called “shots”. Baristas make it by forcing pressurised hot water through finely-ground Coffee beans using a specially-designed machine.
While the likes of cappuccinos, lattes and flat whites are all made using this method, the same can be said about a standalone shot of espresso.
Here, we will look into the latter. Despite having a reputation for being high in caffeine, it very much depends on how much you drink. A shot of espresso coffee, after all, is often served in smaller servings, meaning it can sometimes have less caffeine than standard, brewed Coffee.
As a rule of thumb, you can expect 29-100 milligrams of caffeine in a single shot, typically averaging out at 75 milligrams. A double shot, meanwhile, can have between 58-185 milligrams. It doesn’t take much to realise that that’s quite a lot!
Technically, yes. Caffeine is classified as a drug because it stimulates the central nervous system. It is not, however, a “drug” in the same way that, say, illegal Class-A stimulants are.
In other words, you’re not going to get in trouble for consuming caffeine, although it might still cause side effects. Furthermore, there is a chance that it can lead to addiction and withdrawal.
If you’re worried that your caffeine consumption has become too much, it’s paramount you seek help. Even if it isn’t illegal to take, and doesn’t often cause severe problems like Class-A stimulants, there does remain a small risk.
Please speak to your doctor, nurse or another medical professional if you find yourself in this position, and be sure to follow their guidance.
On the surface, the answer to this question appears obvious. Caffeine can be found inside the leaves of Tea and the beans of Coffee. But, as mentioned previously, there are over 60 plants that naturally contain this stimulant, including Yerba Mate, which we’ve also briefly talked about.
So, what about the rest of them? It would take a long time to explore them all, but let’s now look at a few stand-out choices.
Guaraná (Paullinia cupana) is a vine that originates from South America. Also known as Brazilian cocoa, its components have been used in local soft drinks since 1909.
Its seeds, in particular, contain twice the amount of caffeine as Coffee, thus making them an excellent addition to energy supplements. Indeed, you will likely find this ingredient in a vast multitude of brands available on the market today.
Guayusa (Ilex guayusa) is another example of a caffeinated plant from the South American continent. It thrives in the Amazon Rainforest, and has been used by native tribes for its stimulating effects for centuries.
Finally, we have Yaupon (Ilex vomitoria) and Cleavers (Galium aparine), both of which are the only known caffeinated plants to naturally exist in North America.
Again, although we’ve already covered this, let’s now look at it in more depth. On average, caffeine takes around 45 minutes to take full effect, which can last anywhere from four to six hours.
This is according to a 2008 study conducted at the University of Barcelona and published in the Journal of “Progress in Neuro-Psychopharmacology and Biological Psychiatry”.
Researchers analysed 668 students, 238 of whom were male averaging an age of 22. Each participant had their blood samples taken at 10, 20 and 30 minutes following caffeine consumption.
Furthermore, measurements were put in place twice daily - one at midday and another during the late afternoon. This served as a control in case there were potential differences caused by time of day.
The study concluded that forty-five minutes is the time needed for maximum caffeine concentration. However, levels can reach half this concentration after just a few minutes.
Caffeine withdrawal is an immensely uncomfortable feeling, to say the least. Depending on your usual intake, its symptoms can last for a few days to two weeks.
Those who’re particularly heavy consumers (around 1,000-mg daily), however, may find themselves experiencing withdrawal for as long as two months. So, is there anything you can do to combat it?
If you’re experiencing headaches during your withdrawal, consider over-the-counter painkillers. Alternatively, if you’re looking for natural remedies, there is always the option of using Peppermint oil or even drinking Peppermint Tea.
According to a 2016 study, topical use of this herb may be as effective as acetaminophen at relieving tension headaches.
For the most, though, you should be looking to stay hydrated while getting more rest.
The phrase “Diuretic” refers to promoting the formation of urine. As unpleasant as it sounds on the surface, it has its purposes. In essence, taking a diuretic enables someone to excrete excess water in several ways.
It can benefit those with heart failure, high blood pressure and even kidney disease. But can caffeine in your cuppa offer a helping hand?
The answer, according to one study, is a resounding “yes”. It saw 12 participants abstain from caffeine for five days before consuming 642-mg of caffeine in the form of fresh Coffee.
The results determined that volunteers increased their urine output after once again taking this stimulating chemical compound. The same applies to Decaf Tea and Coffee, although, unsurprisingly, their uses here are limited.
It depends. When most people talk about Jasmine Tea, it is in reference to a type of Flavoured Green Tea.
As we’ve already established, Green Tea contains an average of 30 milligrams per 8-oz cup. (And when over-brewed, it can have up to 41 milligrams.) This applies to Jasmine Green Tea, too, but things change when the focus shifts to Jasmine Herbal Tea.
Jasmine (Jasminum) is a genus of shrubs and vines of the olive family (Oleaceae). It grows in tropical and warm temperate regions of Eurasia and Oceania.
Many commercial products use jasmine flowers. This includes soaps, shampoos, bath-bombs, lotions, perfumes, potpourris and, of course, Jasmine Flower Tea. Due to the latter’s absence of Tea leaves, it is an entirely caffeine-free infusion.
Chai Tea has taken the world by storm in recent years. This beverage can now be found in Tea shops and Coffee houses everywhere - but what is it, and what is its caffeine content?
Traditionally, Chai is a spiced Tea originating from India. Its consumption dates back hundreds of years, with recipes differing from region to region, village to village and even household to household.
The amount of caffeine found in Chai Latte depends on a multitude of factors. For example, Chai Tea made into powder or concentrates may contain less caffeine than those made with a spice blend.
A powdered Chai Latte might have an average of 25 milligrams of caffeine, while a “real” variety could have up to 45 milligrams. Alternatively, we stock several Chai Herbal Tea blends.
