Fact Check

While researching on social media, we found that the same message has been translated and shared in various languages by users who presumed this information to be truthful.

First of all, Factcrescendo contacted Sri Saisudha Hospital in Tirupati to verify the veracity of this message. When we spoke to Dr. Sukumar, he clarified: “I am an orthopedist. This is a false campaign that has been going on in my name for many years. I have never posted a message like this anywhere. Message is totally false. Moreover, it has not yet been scientifically proven that coconut oil has any such benefits against Dengue fever.” 

As Dr. Sukumar said, the message has been circulating on social media in his name since past many years. Here is one such post circulating on Facebook since 2017. since 2017. According to the World Health Organization‘s report on dengue prevention and control measures, dengue may become fatal in the coming years. Significant distress can be expected in Asia, Africa and Latin America. According to a similar study published by WHO, mosquitoes that cause dengue, have a range of flying up to 400 meters, so the claim that mosquitoes do not bite above the knees is incorrect.

Let us share some of the information we found in our research to see if coconut oil has antibiotic effects. Nowhere is it scientifically proven that coconut oil has the ability to fight deadly diseases like dengue.

Monolaurin is a substance that is isolated from coconut oil. It is used to fight simple bacterial, viral and fungal infections. Monolaurin has gained popularity as an effective infection fighter. But Monolaurin is not directly present in coconut oil. A study carried on mice proved that coconut oil does not act as a disinfectant.
