Which type of olive has best anti inflammatory property? And where to buy it from. Thanks?

Arthritis | Olive Oil’s Anti-Inflammatory Effects

A substance found in extra-virgin olive oil has anti-inflammatory effects similar to those of ibuprofen (Motrin, Advil), reports a study in Nature (2005; 437:45–6). The presence of anti-inflammatory activity in olive oil might help explain why its use has been linked to heart disease prevention and improvements in people with arthritis.

Oleocanthol, the substance isolated from extra-virgin olive oil, inhibited two enzymes involved in the process of inflammation (COX-1 and COX-2) but had no effect on a third inflammation-inducing enzyme (lipoxygenase). This pattern of activity is identical to that of ibuprofen. It is interesting that, while oleocanthol and ibuprofen do not have similar chemical structures, both of these compounds cause a strong stinging sensation in the throat.

I have heard of "summer itch" I think it is caused by a small mite. I had a pony that got it last spring, and I looked it up on google. I would have thought the insect spray would have helped, I can't remember what I used, but I also gave her more "gumnuts" for older horses, and after a few weeks, the new hair started showing through and it was just a matter of time and she was back to looking good again. The appearance on my pony sounds much the same as you wrote. If you can, get some "gumnuts" from your horse food supplier and some insecticidal cream. Then just wait for the new hair to grow. If not, then a vet is called for.

They have no such properties.
