What is Dr. Berg's perspective on the potential use of castor oil as a natural remedy for treating cataracts?

While castor oil is beneficial for promoting eyelash growth and has various uses, I recommend N-acetylcarnosine (NAC) drops for treating cataracts. NAC drops are effective because they penetrate the eye and act as a powerful antioxidant, addressing the underlying cause of cataracts—glycation. Glycation involves the binding of proteins to sugar molecules, leading to opacity in the lens. Therefore, NAC drops are more suitable than castor oil for cataract treatment.
