Sesame oil is one of the best oils sustained and doesn't go rancid as fast as most oils. I'm surprised it says put it in your fridge on the bottle. Im sure if you let it thaw out it will be ok. I bought some the other day and just started oil pulling with it. I have to say its a lot tastier than olive oil. Also it goes milky where olive oil stays yellow after i have swished it about.
Im already seeing benefits in my apetite. I don't feel as hungry through out the day, therefore less tempted to indulge in sweets.
