Digging around for info on the health benefits of culinary herbs, I was reminded that the vast majority of the green herbs we use are in the Mint or Labiatiae family. Basil, tarragon, thyme, rosemary, marjoram, sage, oregano, and of course, mint, are all closely related. Botanical types know that one of their characteristic features is opposite leaves and square stems. Culinary types know these plants for their their strong flavor and aroma, deriving from a huge number of exciting phytochemicals, such as terpenes, known to have potent anti-cancer, anti-oxidant, digestion enhancing, and anti-bacterial effects. I found a great site with information on the health effects of culinary spices on cancer, dementia, diabetes, obesity and more: http://www.medicinal-herbs-and-spices.com/index.html.A huge study in 2010 found that culinary herbs are some of the most anti-oxidant rich foods in the diet and provide a significant source of antioxidants when consumed in reasonable dietary amounts. In the same way that fermented foods are "super-raw," I think that herbs and spices are "super vegetables." They pack tons of flavor and nutritional value into tiny packages. A teaspoon of fresh or dried herbs can count as a vegetable serving!
In my neighborhood, rosemary is almost ubiquitous. If you don't have some in your yard, I'll bet your neighbor does. There was a study in 2009 looking at the effect of rosemary on reducing the production of acrylimide in carbohydrate foods cooked at high temperatures. Adding rosemary to bread dough reduced this chemical, strongly linked to breast cancer, by 60%. I make a general practice of adding rosemary to bread dough and roasting potatoes. Plus, it's free. Other fun uses for romemary: traditional hair tonic (make a strong tea and use it as rinse), memory-enhancer in tea or food (I used to bring a rosemary sprig with me into class during exams in acupuncture school), filling the cavity of a roasting chicken with rosemary branches before cooking, and using the twigs as skewers for meat or veggie kabobs.
I'll be teaching a free workshop next Thursday night at the North Berkeley branch of the public library on the seasonal uses of culinary herbs for locavore flavor and health, with a demo on creating herb marinades and condiments. Look here for details: http://www.berkeleypubliclibrary.org/calendars/index.php. And throughout July, a great selection of my Bay Area food heroines/authors are speaking there as well: my foodie pal Vanessa Barrington http://vanessabarrington.typepad.com/, urban farmer extraordinaire Novella Carpenter http://ghosttownfarm.wordpress.com/and "locavore" coiner Jessica Prentice, http://www.wisefoodways.com/home.php.
