I read about oil pulling on this site and decided to try it, though i wasn't aware of any real health problems. I only had olive oil in the house so I went with that for 3 or 4 days and did the neti pot nasal flush afterward each time. I used a tablespoon of oil and swished for 15 minutes, rinsing afterward with 1/2 tsp. salt and 1/2 tsp. baking soda in warm water. Throughout the course of those four days I noticed a startling mood elevation and mental clarity that I hadn't had in a very long time. I also noticed alot of sinus drainage and my ability to smell increased. Also my eyes stopped feeling itchy or dry. I switched over to sesame oil because it was recommended, but have since switched back to olive oil and experienced the same mood elevation and mental clarity. This has made me wonder if I was suffering from low-grade depression the whole time. I feel much calmer and focussed, less confused and find alot more reasons to laugh during the day. I also have a TON more energy and work much harder. This energy caused me to have some problems sleeping for the first few days. One last thing is that my beard seems to have gotten much thicker and softer. I'm excited about such a cheap and simple remedy and would recommend it to everyone.
