If the incision has a lot of tension (is very tight), some surgeons will leave the sutures in longer. However, 12 days for suture removal may be a little long and runs the risk of leaving suture marks or railroad track scars. You should call your surgeon's office to have your concerns addressed.
Parsley is popular in Italian seasonings. Chicken cacciatore is flavored with oregano, garlic, and basil. Along with tomatoes and mozzarella, freshly picked basil is used to make insalata caprese. Oregano is a common Italian seasoning.
But, I would recommend you not mix your spices into a homemade Italian seasoning mix, for a few reasons. First, some of the core mix are better dry, like Oregano -- Oregano needs to dry out to attain full flavor. Others, like Basil absolutely suck dried out, and taste way, way better fresh. Most spices taste better fresh. Second, most legit Italian food doesn't use a big mix-o-spices.
