I'm using sunflower oil some days, coconut oil some days. Tried the sesame oil and don't care for the taste but is a back up if I run out. My daughter claims it helps her too to OP with her allergies. I'm not saying it has cured it but I haven't had asthma since I started OPing. I was having it before though and here in our area of Tennessee I always have trouble with allergies and asthma. Even if I get an asthma attack down the road, not having them right now is a real blessing to me. When I do get an attack though I try not to take the spray cause of the steroids in them so I will either drink a Breathe Easy tea or take Dr. Christopher's Lung and Brochial capsules. I'm a big fan of Dr. Christopher and his herbal remedies. You can read about asthma, sinsus and such on this page if you like http://www.herballegacy.org/Asthma.html.
I wish there was a forum for those that like his products.
I pray you get relief soon! I know exactly how you feel. Even my husband though who was having lots of sinsus problems says he doesn't have them anymore.
