I avoid anything with coconut oil in it! It gives me terrible migraine headaches. My whole family runs this allergic reaction. Now, I don't know if it's "virgin" - it's the C.O. you see in lots of products (candy, esp.) A small amount can set me back for a day; more has caused me a visit to the ER! I did not run across anyone else who said they had the same reaction, but my dad, aunts, cousins, etc. all are allergic to C.O.

I think I've finally discovered the cause of my awful migraine headaches - VCO. I couldn't put my finger on it because I was taking so many supplements. After eliminating almost everything else I think VCO is the culprit. The reaction only happens when I take a couple spoonfuls of it but it's awful. Like Tammy it's the kind of headache that sets me back a whole day.

I thought I was doing my friend a favour by massaging his back and face with organic cold pressed coconut oil. Two hours his skin was burning. The next morning his face had come up in numerous blisters which took a couple of weeks to heal. Please test for allergic reactions before using.

Hi, I just read that somebody used Parachute coconut oil internally and fell sick. Parachute coconut oil is a well known hair oil brand in India and I am sure it's written somewhere on the pack that it is not meant for internal use. 100% pure doesn't imply virgin oil. I am sure you understod why you fell sick. Its a hair oil.

Parachute 100% coconut oil is edible coconut oil. It can be used as food. It says on the pack also in the instructional text that it is 'edible oil'. Its a misconception that Parachute coconut oil is a hair care oil only. I have used Parachute coconut oil on my food for many years, and its safe.

I believe that almost any time you detoxify your digestive system, you're likely to feel ill. maybe not violently ill, but you're body is going to force stuff out and learn to cope with issues in a better way. Yucky feelings= changes

Reading the feedback on nausea following the first few days of the oil was helpful if only i had found it earlier starting slowly is so important as after initial dose of only one dessert spoon i was sick with terrible headaches almost ten minutes after first dose felt sick rest of day. so i am now proceeding with a little caution.... as I don't want to miss out on all the benefits i read about. will update on progress soon.

Coconut oil helps me with digestive problems and sinus issues. I have less upset stomach than before. I would highly recommend that you don't just eat the oil with food... but use it to cook food like veggies or eggs. You will still get the benefits. Think about it. You wouldn't dip into a tub of butter and just eat it... or drink vegetable oil. Treat this the same way... use it in food or to cook food.... you may find that you tolerate it much better this way. Also do not confuse coconut oil with coconut milk or juice... they are three different things.

I put a teaspoon of organic virgin coconut oil in my tea after dinner a month or so ago and within 30 minutes I was throwing up! Yuck. Now I can't stand the smell of coconut oil. But I do rub it on my hands every day (and rub in another moisturizer on top of it to mask the smell). I have the softest hands now!

I have a question for the people who say that they got a severe upset stomach and/or diarrhea. What type of coconut oil did they eat? I have been using coconut oil in cooking and only use organic Virgin Coconut Oil and my family has never experienced any symptoms like that. I understand there is a huge difference between Virgin Coconut oil and coconut oil.

Coconut oil also gave me and my mom both major stomach discomfort and diarrhea. We were told it can do that the first few times, but it will quit. I just cut my dose to 1 tsp instead of one tbsp. Starting off real slow, then building up the dose.

I tried Coconut Oil for the first time yesterday. It gave me an upset stomach, and felt quite nauseous. Nibbling on food helped. About 8-10 hrs later I had terrible diarrhea and continued to feel nauseous. I don't know whether this is an initial reaction... and if I try again I will tolerate it better?? Whilst I didn't mind eating it neat yesterday - the thought of eating it again now makes me feel ill. The sad thing is that I am on Thyroxin for an under active thyroid... and really hoped this would help. :(

I have an underactive thyroid...and I take Thyroxen early morning, then I have breakfast,(to fill the stomach)..then a Table spoon of Coconut oil ,that I dilute in hot water (put the Coconut oil in something first)..I use this for my metabilism...and it works...I had noticed in the beginning,my heart racing little, but that was my body getting used to it...also use the same method to put in running at water,body is lovely and soft after...or you can apply,the oil as it is...all over body,under and over eyes...fantastic...no puffyness,I suggest,applying over the eyes when you're ready for bed...otherwise it can become a little blurry :-)...

On my jar of oil it says to refrigerate after opening. Could these cases of nausea, etc. be from leaving it out and it has spoiled? I have taken fish oil tablets that went bad after about a year.

I did not lose any weight with this and after two months, it started to make me ill. It is also very confusing to which is extra virgin or not.

First off, people taking coconut oil or who are thinking of taking c.o. internally must make sure they are ingesting the "Mother" or PURE ORGANIC C.O.. To all the people who are experiencing nausea, diarrhea etc., might want to read up on "candida die-off". Because C.O. is an anti-fungal, these reactions might be the result of big quantities of YEAST cells dieying off creating toxins. It is a good thing as you are killing the yeast fungus living in your body in mass quantities. Picture a thousand rotting corpses left to rot inside a sealed building, can you imagine the gases & smell? (Sorry about the visual, it's the best I can describe the process). That could be why so many people are experiencing the same side effects. There're are more candida die-off symptoms listed. It's a get-worse before-you-get-better deal, that's if were dealing with a yeast overgrowth problem of course. Good luck to all.
