Purple sweet potato GI upset

Anyone found purple sweet potatoes to irritate your stomach/digestive system?

So I got some gnarly little purple sweet potatoes from Sprouts. Literally gnarled little roots, but beautiful in their own light. Their skin was a little deeper purple than usual and when I cooked them up the flesh was very, VERY deep purple and had an unusual texture with very sticky consistency. They even tasted and smelled different. Not bad, but different.

I ate a small one (about 5-6 ounces) for lunch and had a weird not-quite-headache feeling that reminded me of a reaction I have to some food colorings. I'm sure these weren't artificially colored, but maybe they were bread to produce an excessively purple flesh that isn't colored only with the wonder-food substance in the Okinawan (light-skinned) variety? Now my head feels better but my stomach is a little upset.

I'm just wondering if there could be something dangerous here. I have about 5 potatoes left and I'd hate to throw them out without some due diligence but it's tough to find good info on these unusual little tubers.

<EDIT>

These may have been "Stokes Purple" sweet potatoes. The look is about right.

</EDIT>

Did someone come in and make the word "Sweet Potatoes" into a link?

Different Stokes for different folks.

Out-of-season makes sense. I was in a hurry so didn't notice but I'd guess these were grown in SoCal since it was, after all, sprouts and a major local grower has recently been licensed to grow Stokes Purple sweet potatoes. The color was so vibrant though I'm still wondering if I had a reaction to the pigment like I sometimes do to artificial coloring.

I'm not sure of the season for them but I have noticed that they started to get smaller after Thanksgiving and more gnarled until they left the shelves in the store. Could be a bad batch, under-grown and not ready for consumption? The last ones I bought had some rot, so I threw them out. Right now in Oregon I've been buying the purple potatoes whenever I find them, usually locally produced and delicious. My kids love them loaded with butter, who wouldn't ?
