I too have suffered the curse of pruritis ani.
My story, however, is a personal triumph: a tale of investigation, introspection and ultimately, diagnosis and cure.
During my first bout with the dreaded scourge, I hustled over to my favorite GP. I didn’t have hemorrhoids or pinworm. My GP informed me that this condition could be caused by irritation and advised against the use of soap (my custom) in the affected area. He told me as well that food allergies (sensitivities?) can cause this. He mentioned chocolate, coffee and alcoholic beverages as primary offenders (why is it that we are hurt most by the one’s we love?), but that many other foods could give you an itch to remember. At visit’s end, for some unaccountable reason, the friendly and sage GP eschewed my hearty, firm handshake.
As a long-standing and devoted consumer of the afforementioned pro-pruritic triad, I reasoned that they probably wouldn’t have turned so suddenly on me. Something else must have been causing my itch. A new food, perhaps? I racked my brains.
Then, it hit me. I had recently purchased a Costco membership and was bringing home many new things in extravagant amounts. I found I could not resist the three pound jars of cashews. I ate them daily and in large portions. And when I stopped, slowly the itch faded.
However, as an empiricist (and someone with an abiding fancy for cashews) I didn’t quit at that. Over the intervening years since the initial discovery, I’ve sampled cashews on no fewer than three occaisions. The result: a deep appreciation for benadryl in both it’s capsule and cream forms.
Further reading on the topic indicates that the cashew nut shell contains an urushiol (also the active ingredient in poison ivy) and the shelled nuts are often contaminated with the urushiol oil. Roasting is supposed to destroy the toxin. But let me tell ya brothers and sisters, whatever Costco is doing to their cashews, it sure ain’t destroying all the toxin. And my digestion doesn’t take it out either. The locality of the itch corresponds to the those nether regions that contact the cashew nut oil on its way out.
Granted, I’m probably hypersensitive (immunologically speaking). My mom and brothers don’t admit to having similar difficulties. But I bet there are others suffering with the dreaded cashew nut itch. My only wish is that they may profit from my experiences.
