Dr Cyriac Abby Philips, famously known as ‘The Liver Doc,’ has recently criticized actor Nayanthara for sharing unverified health benefits of hibiscus tea on social media. Previously, Dr Philips called out actor Samantha for promoting hydrogen peroxide nebulization. Now, he has turned to Nayanthara’s claims regarding hibiscus tea.

In a now-deleted Instagram post, Nayanthara credited nutritionist Munmun Ganeriwal and praised hibiscus tea, stating, “This has to be my most favourite tea and the most exciting one in the meal plan curated by the genius @munmun.ganeriwal.”

“It has long been used in Ayurveda. It is high in antioxidants and is helpful in diabetes, high cholesterol, high blood pressure, and heart-related ailments. It is very cooling for the system hence it is great for those who have acne, heat boils on skin etc. Hibiscus tea is great for the monsoon season as it is rich in vitamins and keeps our immune system in equilibrium. It has antibacterial effects that protect from seasonal infection/illness," her post read.

Dr Philips, known for debunking health misinformation, took to social media to address Nayanthara’s claims. He took to his X (formerly Twitter) handle, “If she had stopped at hibiscus tea is kind of tasty, that would have been ok. But no, they have to go ahead and blow their health-illiteracy trumpet and also claim that hibiscus tea is helpful in diabetes, high blood pressure, acne, antibacterial and protects against the flu.”

Dr Philips highlighted the lack of specification in Nayanthara's post regarding the type of hibiscus used, whether it was “Hibiscus Sabdariffa (or Roselle), or Hibiscus Macranthus.” This distinction is crucial as different species may have varying effects and nutritional profiles.

He further pointed out that there is insufficient scientific evidence to support many of the health claims associated with hibiscus tea. For instance, while some studies suggest that Hibiscus Sabdariffa may have a mild blood pressure-lowering effect, these results are not conclusive, and more research is needed. Regarding blood glucose levels, Dr Philips stated, “There is no credible evidence that hibiscus tea has any blood glucose-lowering effects, and hence cannot help with diabetes.”

Dr Philips debunked claims about hibiscus tea’s effects on acne and its purported antibacterial properties. He emphasized that no studies have proven that hibiscus tea can prevent acne or seasonal infections in humans. The antibacterial effects observed in hibiscus are generally limited to laboratory settings and do not translate directly to practical health benefits for humans.

Dr Philips’ critique post explains the importance of relying on scientifically verified information, especially when it comes to health and wellness. Celebrity endorsements can significantly influence public perceptions and behaviours, making it essential for influencers to share accurate and reliable information.
