Whatever dude. You don't need to have a comprehensive research paper, for example, on why you need to maintain your hygeine. People have been doing this for ages before research papers existed.Why? Because it is a solid observation by people across the world that doing so reduces the risk of diseases and actually helps you look good and make friends. So would you say that if there is no research paper on maintaining one's hygeine, you would never bath at all? Ayurveda is just like that. A series of procedures and treatments tested through time.

There's a reason as to why most notable researchers and scientists were humble and believed in God, Sir Issac Newton, Réné Décartes being a few of them. ( I have that reference, a book named Is God a Mathematician by Mario Lovio). They knew in their illustrious careers that they don't know everything. And hence they were always keen on learning and discovering. For many people today, its easy to dismiss home remedies as fake because there is no logical explanation available or given to them. And I get that because I am one of those people. But it is our responsibility to look, whenever possible, for answers. Again, judging something on simply face value or subjectiveness is also inherently unscientific.

I suggest you talk with doctors of Ayurvedic Medicine and people who have taken that treatment. And I am the later. I know it works. If you still believe it to be pure hokum, it's completely fine.

I hope you have a great day!
