I had the same experience; that's how I came upon discovering this.
I have had both raw and cooked coconut oil many times before as well, but the last time I made french fries I had a *strong* cleansing reaction and put it together.
There was a strong soapy smell to it so the lauric acid must have been liberated.
Soap is probably one of the best wormers possible, but making it palatable is tricky. Now that I'm thinking about this I would bet that this could be a very good way to target flukes in the liver as fat acts as a nutrient transport to the liver.
