Before We Start: Defining Some Basic Kidney Terms
Your kidneys are truly amazing. A healthy set of kidneys filters about ½ cup of blood every minute! They remove excess water and wastes from the blood .
Kidney infections occur when bacteria from the gut travel through the bladder and up to the kidneys . These are usually treated with antibiotics, and if you talk to your doctor, you may be able to add herbs to your treatment regimen to help ease pain and other symptoms.
Kidney stones are made up of crystal-forming substances, such as uric acid, calcium, oxalate, or cysteine. High levels of these in the urine and too little fluid to dilute them can cause stones . Drinking more fluids, changing the diet, and sometimes medication are used as preventative approaches .
Kidney disease or failure involves the loss of kidney function. Some causes include:
Now, lets find out how your favorite beverages might play into all this.
Do I Need To Worry About Its Impact On My Kidneys
Green tea can in fact damage your kidneys. Like green tea and its impact on your liver, for example, too much green tea or green tea extract can be toxic. The harmful effects of green tea are often due to three major factors: Its caffeine content, the presence of aluminum, and according to Chinese Medicines review the effects of tea polyphenols on iron bioavailability. Green tea should be avoided if your doctor states so if youre suffering from heart conditions or major cardiovascular problems. It is recommended that pregnant and breastfeeding women need to limit their amounts of green intake to two cups a day.
For those suffering from renal failure, high levels of aluminum can lead to neurological disease. For the larger popular, up to 10 small cups of green tea, a day is likely fine according to Chemical Biology and Pharmacognosy Professor Chung Yan. At the end of the day, chances are most of us tea lovers do not need to worry but it is important to know what impact green tea does have on the body!
High Caffeine And Kidneys: Lets Explore Some Popular Drinks
Unfortunately, the effect of caffeine on the kidneys isnt great. Caffeine consumption is a risk factor for kidney disease, and can cause scarring of the glomeruli that is, the vessels in the kidneys that filter blood .
Caffeine may also lead to kidney stones, and it increases strain on the kidneys . However, some caffeinated beverages, like coffee, may be safe in small amounts due to certain plant constituents .

Can Drinking Too Much Tea Damage Your Kidneys
Well, there is a common misunderstanding that all teas are made from a dehydrated or roasted version of a tea leaf. This is true, but not for all teas. Green tea is made from unoxidized leaves and is much healthier than regular tea. The process of oxidizing the leaves in regular tea is what makes it lose its nutrition value..
Coffee Consumption And Kidney Disease: What Research Says
For a while, coffee was considered potentially dangerous to the kidneys however, the relationship may be more complex than originally thought. There have been numerous studies on the correlation between coffee consumption and kidney disease. Population-based epidemiological studies tend to show a link between coffee consumption and possibly a protective effect on kidney function.
For instance, a study from Korea involving over 2,600 women revealed that coffee consumption was associated with a decreased risk of kidney disease, including in diabetic women. However, population-based surveys arent enough to make hard conclusions. So, given the possibly controversial and pertinent nature of the topic, a meta-analysis published in 2016 attempted to answer this same question.
This meta-analysis revealed that theres no link between coffee consumption and increased risk of kidney disease in male patients. Interestingly, however, the study noted the possibility of a reduced risk of kidney disease in women who drink coffee. Based on these data, the conclusion regarding coffee could be harmless on male kidneys, and possibly beneficial for womens kidneys.

Choosing Tea For Kidney Health
So, is there a best tea for kidney disease? Some herbal teas can help target or prevent specific kidney-related problems, but it’s important to ask your doctor before drinking them regularly, especially if you have serious kidney issues. Many of the studies related to potential “kidney cleanses” have not been undertaken in large-sample, human trials.
A September 2016 study published in the Asian Journal of Urology found that Blumea balsamifera, or sambong, decreased the size of laboratory-grown calcium crystals, which are formed from urine minerals. The study used a commercially-available tea. Sambong may also prevent the formation of these crystals. If too many larger crystals stick together, they can form painful stones. Sanbong’s crystal-decreasing action potentially lowers the risk of kidney stones. Sambong is derived from a tropical shrub.
One type of hydrangea shrub, Hydrangea paniculata, features cone-shaped flowers. It also boasts medicinal properties. Research published in the December 2017 issue of Frontiers of Pharmacology focused on the high presence of the beneficial compounds in hydrangea that are known as coumarins. Coumarins have antioxidant and anti-inflammatory properties. According to animal studies, ingesting hydrangea can have protective qualities, at least in the case of kidney injury. Hydrangea paniculata is available in “kidney cleanse” blends. Whether it’s the best tea for kidney disease is, of course, a question your doctor can help you solve.
