Argan Oil cured my chronic sinusitis in 2 days!! I'm only taking 1 teaspoon of culinary Argan oil (the edible type from the Middle East that people cook with) and already my sinusues are completely clear! I was told that the typical dose a day is just under a tablespoon - and I'm only taking 1 teaspoon! Yesterday, I did get a bit of a healing crisis as my sinuses cleared out - today they are totally clear, and I've been suffering with this for MANY YEARS already!! I read that argan oil helps boost the immune system, which is why I took it. You can go to PubMed and type in argan oil to see more health issues it helps with. Make sure you buy a kind of argan oil from the Middle East - Israel or Morocco. The kind I tried is from Israel. This remedy is most definitely worth a try!!!
