Oolong Tea Side Effects
Can It Harm You?

There are oolong tea side effects, just like any other tea beverages. The key is to avoid the low quality teas.

Oolong tea is a hybrid between black tea and green tea.

Its chemical composition is intermediate between the two. It is a healthy beverage, but like any other tea, does have some minor side effects.

Compared to its benefits, these side effects are like 1000 times more insignificant. That is why scientists and doctors are urging us to drink more tea.

Diet Oolong Tea?

There are many different types of oolong tea, ranging from the lightly oxidised oolong (e.g. Taiwanese Baozhong) to the heavily oxidised (e.g. Taiwanese Oriental Beauty).

There is not such thing as a diet oolong tea. All oolong teas help to lose weight. Scientists have not found any "weight loss" variety.

Which Oolong Tea?

The best way to avoid oolong tea side effects is to buy from a vendor who knows their teas inside out and also sells high grade tea.

Their teas are more likely to have come from a high quality tea garden in the mountains, rather than from some low grade, contaminated sources.

Avoid the shiny diet oolong tea sellers who are more interested in selling you the hype than demonstrating an in-depth understanding of their teas.

I include below a list of known oolong tea side effects, which will apply to any other tea beverages.

Caffeine Intolerance

For those who are sensitive to caffeine, here are the symptoms to watch out for: restlessness, irritability, sleeping problems, tremor, heart palpitations, loss of appetite, upset stomach, nausea, frequent urination and skin rash.

Fortunately, when it comes to caffeine, oolong tea occupies a sweet spot between green tea and black tea. Learn how you can avoid oolong tea caffeine side effects.

Oolong Tea Caffeine

Stomach Upset

Caffeine and tannin can cause stomach upset by stimulating the production of gastric acid.

Tea can be a problem for those prone to heartburn and stomach ulcer. Heartburn results when gastric acids rise up and spill into the oesophagus, causing irritation.

Thiamine Deficiency

Tea reduces the absorption of thiamine, or vitamin B.

Thiamine deficiency leads to a condition known as beriberi. Once common to sailor, beriberi is now relatively rare in the Western world except for alcoholics.

Tea Allergy

Tea contains tannin and caffeine that may cause allergy to some people. If you are hypersensitive to caffeine or tannin, avoid drinking tea.

Medical Interaction

Tea can interfere and interact with certain medications. As a safety precaution, avoid drinking tea for at least 2 hours after taking medications.
