The Side Effects of Pu-erh


You may be wondering what is all this about pu-erh tea. This is a variety of fermented and aged dark tea produced in Yunnan province of China named after Pu’er city. It’s made from Camellia Sinensis leaves. It undergoes microbial fermentation for up to years then is processed and sometimes added flavor and is ready for consumption. The tea has been known to reduce cholesterol, indigestion, and is refreshing to the mind. But before you run out to get it, here are some side effects you should know about the tea.

High blood pressure

Imagine you having given up on coffee and sodas for health purposes, for example, because you already have high blood pressure or maybe because you are not a fan of the drinks, then you resort to drinking more of this tea. What you don’t know is that the drink, like the other stimulants, can cause high blood pressure due to the high amounts of caffeine it contains. If you are not familiar with health implications of caffeine, you probably don’t want to drink too much of this tea.

But if you decide to drink it on a regular basis, you should give up on other stimulants such as caffeine. High blood pressure may be fatal and also, may bring along other diseases like glaucoma. This happens because the tea increases pressure in the eye occurring within 30 minutes and lasting for up to 90 minutes after ingestion. Eventually, this may bring blindness.


During pregnancy, what the mother ingests gets to the baby. This also applies during the breastfeeding period. Taking high amounts of the tea will negatively affect your baby in that it may cause diarrhea, sleeping disturbances, and even irritability. Too much of it may cause premature delivery and low birth weight. And more devastatingly, it may cause miscarriages.


Research suggest that caffeine may affect how the body uses sugar; this is a worry to anyone suffering from diabetes. Consult your doctor before taking the tea.

Irritable Bowel Syndrome (IBS)

The caffeine in the tea may worsen the IBS symptoms or it may worsen diarrhea especially if taken in large amounts. You want to reduce the consumption of this tea if you have a history of suffering from irritable bowel syndrome.

Osteoporosis or weak bones

Yet again, caffeine is the problem here; it increases the amount of calcium lost in urination upon consuming in high doses. If you already have osteoporosis, you should take more calcium-rich foods to replace the lost calcium. A type of the Pu’er brick tea has been known to have very high flourine levels. This is because it’s made from tea leaves and stems that accumulate fluorine, and its consumption may lead to fluoride poisoning, a condition called fluorosis that affects the bones and teeth.

On top of that, the tea may worsen any bleeding disorder because of the caffeine in it.

It’s important to note that the tea is not to be mixed with other specific drugs such as Amphetamines, cimetidine, and cocaine to mention a few. The interactions will have major side effects such as headaches, heart problems, and jitteriness. Pu-erh is good for your health but moderation is key.
