Hibiscus tea is a popular worldwide tea because of all of its health benefits.  It does have several potential side effects.  These Hibiscus Tea Side Effects are not all negative; many of them are actually positive for a majority of the population.  Below I will include a list of what you can do to prevent negative side effects of Hibiscus Tea.  Please don’t let this list scare you; herbal tea is actually considered to be one of the safest versions of tea.

 Low Blood Pressure

Hibiscus Tea Side Effects

Hibiscus tea can lower blood pressure.  If you are already have a lower blood pressure, you would want to be aware of this side effect. Knowing this, you should reduce your intake of the tea to prevent a blood pressure that is lower than what is good for you.  If you are taking medications to lower your blood pressure, make sure to speak with your healthcare professiona and consume the tea in moderate amounts.

Hibiscus Tea Side Effects

Hibiscus tea improves digestion and bowel movements for a majority of the population.  It is often conceived as a mild laxative and diuretic. Improved digestion helps your body eliminate waste more efficiently, which leads to better overall health. However, I would not substitute laxatives with herbal tea. Doing so can lead to discomfort and issues in the bowels.  Gas, bloating, and mild stomach cramps are some symptoms to recognize if you are drinking too much tea.


Hibiscus Tea Side Effects

Hibiscus tea may slightly lower estrogen levels in the body. The estrogen levels may drop lower than wanted and may also interact with birth control.  If you are on birth control, you should speak with your doctor and never consume in huge quantities.

Fertility and Pregnancy

Hibiscus Tea Side Effects

Hibiscus tea, as previously stated, lowers estrogen levels. Lower estrogen levels can have a negative effect on fertility and the ability to reproduce. There aren’t any studies related to how this affects the fetus, but according to an article by the International Journal of Obstetrics and Gynecology, it may increase the risk of going into labor too early.

Interaction with Prescription Medications

Hibiscus tea may cause complications when taken along with some prescription medications including cancer medications. The National Cancer Institute states that you should avoid hibiscus tea if you are undergoing radiation or chemotherapy.

Hibiscus tea can interact with some medications. Besides interacting with the cancer drugs mentioned above, it can nullify the effects of anti-malaria drugs, and it boosts the effects of anti-viral medications. Hibiscus tea changes processing of some of the anti-inflammatory drugs are by your body. It is recommended that you wait 2 hours after taking anti-inflammatory medications to drink hibiscus tea.

Hibiscus Tea Side Effects: Dizziness

Being dizzy is also another side effect that can occur after drinking hibiscus tea .  Hibiscus tea can cause some consumers to feel light-headed, sleepy, and dizzy after drinking it.  It is because in some individuals hibiscus tea can have a different impact on blood flow. It is best to make sure that you do not have any of these side effects before driving or operation heavy machinery.


hibiscus tea antioxidants

Hibiscus tea contains a great deal of antioxidants and minerals, but one doctor warns that you should not consume more than one quart of hibiscus tea a day. Due to the acidic nature of the beverage, aluminum content, and manganese content, you should abstain from drinking over this amount.

 Improved Liver Health

You may be wondering why improved liver health is considered a Hibiscus Tea Side Effect. This is prime example of a benefit that, without limits, could become a bad thing. You can’t forget that too much of a good thing can become a bad thing.  Hibiscus tea may promote liver health and help reduce fatty liver in overweight patients, but in high doses, the tea can actually have the opposite effect. The tea can actually become toxic to the liver if the consumer is not careful about watching how much they drink.


Hibiscus Tea Side Effects

Many forms of herbal tea have the potential to cause allergic reactions.  Hibiscus tea has a low potential to be an allergen for some people. This can develop as hay fever, itchy eyes, watery nose after drinking the tea.

Reduced Blood Sugar

Hibiscus Tea Side Effects

Hibiscus tea is known to lower blood sugar levels. If you have diabetes and have low-uncontrolled blood sugar, you may want to steer clear of this specific tea. WebMD warns that due to hibiscus tea affecting blood sugar levels, anyone having surgery should avoid drinking the tea at least two weeks prior to a scheduled surgery so that their blood sugar levels can controlled without complications.

  1. I was drinking hibiscus tea when I was fasting and also eating raw garlic to help do a Candida cleanse. I felt really faint and lightheaded and dizzy at times. I realize the garlic could be causing it but then this article really helped me figure out that I was drinking too much of the tea. Thank you for the information. I think I may have low blood pressure also.

    1. Leanne,

      That is a scary experience! We are glad to know that this article was able to help you find the cause of your symptoms.

      Its so important to maintain a healthy balance. Too much of one thing can always have unintended consequences!

  2. I love how it tastes and recently started drinking too much…I guess.
    I was making it as suggested for iced tea…2 bags per 6 ounces…I thought very strong. I had the tea for about a week but developed some serious stomach issues…pain, gas, constipation. I still have these symptoms and stopped the tea altogether about 2 days ago.

  3. Tea lover: unfortunately i start to cough and get a raspy throat, like i am ill. This is just taking a few sips of tea. I tried it again and it did the same thing. So hibiscus is not for me.

    1. Annie,

      We definitely understand. Not all teas are ideal for all people. Better to stay on the safe side and listen to your body. Remember, always consult with a medical professional. Please let us know if you find a more desirable alternative!

      Be safe!


  4. I’m not sure but I think this tea is making me very dizzy and giving bad headaches. I have high blood pressure and recently went off verapamil. I tried drinking this tea and it definitely lowers blood pressure but I think I’m consuming too much.
    Bought a medicinal brand that has 1.200 milligrams per bag
    I was drinking 3 a day.
    I got super dizzy and it lasts most of the day.
    I just cut out that brand and am drinking tea that has other berries as well
    But I’m still dizzy with headache.
    I cut down to 2 cups.
    I hope this helps
    I don’t want to go on meds with all their horrible side effects.

    1. Rebekah,

      I hope you’re beginning to bounce back. It sounds like you need to consult with a medical professional. Better to be safe than sorry. Everyone is a little different than the next. Be safe and keep us posted!
