Okay, I am new here but I have experimented with coconut oil. One thing to know about it, it is highly anti-microbial/fungal/parasitic. Many people have fungal infections without ever realizing it. The confusion systems may have actually come from some amount of yeast die off, which can cause flu like symptoms.
As far as the cold sore, most people carry it but few experience symptoms. Coconut oil is high in arginine, which can help trigger cold sores, especially when taken with diet high in sugar, processed foods, and bad fats.
