Thyme

Health Benefits
(Source: World's Healthiest Foods, George Mateljan)

Thyme has a long history of use in natural medicine in connection with chest and respiratory problems including coughs, bronchitis, and chest congestion. Only recently, however, have researchers pinpointed some of the components in thyme that bring about its healing effects. The volatile oil components of thyme are now known to include carvacolo, borneol, geraniol, but most importantly, thymol.

Significant Anti-Oxidant Protection of Cellular Membranes

Thymol—named after the herb itself—is the primary volatile oil constituent of thyme, and its health-supporting effects are well documented. In studies on aging in rats, thymol has been found to protect and significantly increase the percentage of healthy fats found in cell membranes and other cell structures. In particular, the amount of DHA (docosahexaenoic acid, an omega-3 fatty acid) in brain, kidney, and heart cell membranes was increased after dietary supplementation with thyme. In other studies looking more closely at changes in the brains cells themselves, researchers found that the maximum benefits of thyme occurred when the food was introduced very early in the lifecycle of the rats, but was less effective in offsetting the problems in brain cell aging when introduced late in the aging process.

Thyme also contains a variety of flavonoids, including apigenin, naringenin, luteolin, and thymonin. These flavonoids increase thyme's antioxidant capacity, and combined with its status as a good source of manganese, give thyme a high standing on the list of anti-oxidant foods.

Time's Up for Microbes with Thyme

The volatile oil components of thyme have also been shown to have antimicrobial activity against a host of different bacteria and fungi. Staphalococcus aureus, Bacillus subtilis, Escherichia coli and Shigella sonnei are a few of the species against which thyme has been shown to have antibacterial activity.

For thousands of years, herbs and spices have been used to help preserve foods and protect them from microbial contamination, now research shows that both thyme and basil contain constituents that can both prevent contamination and decontaminate previously contaminated foods. In these studies, published in the February 2004 issue of Food Microbiology, researchers found that thyme essential oil was able to decontaminate lettuce inoculated wth Shigella, an infectious organism that triggers diarrhea and may cause significant intestinal damage. In addition, washing produce in solution containing either basil or thyme essential oil at the very low concentration of just 1% resulted in dropping the number of Shigella bacteria below the point at which they could be detected. While scientists use this research to try to develop natural food preservatives, it makes good sense to include thyme and basil in more of your recipes, particularly for foods that are not cooked such as salads. Adding fresh thyme and/or basil to your next vinaigrette will not only enhance the flavor of your fresh greens, but will help ensure that the fresh produce you consume is safe to eat.(March 25, 2004)

A Nutrient-Dense Spice

The range of other health-supportive nutrients found in thyme is also impressive. This food emerged from our food ranking system as an excellent source of vitamin C, a very good source of vitamin A, and a good source of iron, manganese, copper, and dietary fiber.
