Can hibiscus tea cause kidney stones?

Answered by Phillip Nicastro

According to a study, the calyces of the hibiscus flower have been found to have anti-urolithiatic properties. This means that they can potentially help prevent the formation of kidney stones. So, in fact, drinking hibiscus tea may be beneficial for kidney health and does not cause kidney stones.

The study specifically looked at the effects of hibiscus calyces on urolithiasis, which is the medical term for the formation of stones in the urinary tract. The researchers found that the calyces of the hibiscus flower contain certain compounds that can inhibit the formation of crystals, which are the building blocks of kidney stones.

One of the main compounds identified in hibiscus calyces is hydroxy citric acid, which has been shown to have a protective effect against kidney stone formation. This compound helps to increase urine volume and decrease the concentration of stone-forming substances in the urine, thereby reducing the risk of stone formation.

In addition to hydroxy citric acid, hibiscus calyces also contain other bioactive compounds like anthocyanins and polyphenols, which have been found to have antioxidant and anti-inflammatory properties. These properties may also contribute to the prevention of kidney stone formation by reducing oxidative stress and inflammation in the kidneys.

It’s important to note that the study found no harmful effects of consuming hibiscus calyces or hibiscus tea. This means that incorporating hibiscus tea into your diet is unlikely to cause any negative effects on kidney health or increase the risk of kidney stone formation. However, as with any dietary change, it’s always a good idea to consult with a healthcare professional if you have any specific concerns or medical conditions.

The research suggests that hibiscus tea, made from the calyces of the hibiscus flower, may have a protective effect against kidney stone formation. The anti-urolithiatic properties of hibiscus calyces, including compounds like hydroxy citric acid, may help prevent the formation of kidney stones by increasing urine volume and reducing the concentration of stone-forming substances. As always, it’s important to maintain a balanced diet and consult with a healthcare professional for personalized advice regarding kidney health.
