There is a myriad of natural foods and compounds that have been studied
for their disease-preventing and even disease-treating abilities. While the
pharmaceutical industry pushes patented drugs that cause numerous side-effects,
researchers are unveiling how we can use nature’s gifts to prevent and treat
ailments ranging from diabetes, to arthritis, to even cancer. For example,
Chinese researchers have shown how oils as simple as chamomile or
thyme can kill up to 90+ percent of breast cancer cells.
Studying some of the most popular essential oils in current use, such
as mint, ginger, lemon, grapefruit, jasmine, lavender, chamomile, thyme,
rose, and cinnamon, researchers sought out to discover how these oils may combat
cancer. They did so by testing antibacterial potency as well as in vitro
toxicology against human cancer cell lines. The cancer cell lines evaluated
were the MCF-7 breast cancer cells, the A-549 lung cancer cells, and the PC-3
prostate cancer cells.
At a concentration of about 0.2%, all of the essential oils were
relatively effective at inhibiting both the prostate cancer cells and the lung
cancer cells, with the exception of mint essential oil.
Though when it came to the breast cancer cell lines, some of the oils
were especially effective. Essential oils from cinnamon, thyme, chamomile,
and jasmine were significantly potent against the breast cancer cells
lines, offering greater protection.
The breast cancer cells were mostly destroyed by all four of these
oils, with chamomile killing up to 93% of them in vitro. Even more
effective was thyme oil, which led to a 97% kill rate of the
MCF-7 breast cancer cells. Though it is important to remember that this
research was performed in vitro – meaning that the cells were studied
outside their normal biological context – like in a petri dish.
“For MCF-7 cell, the cytotoxicities of cinnamon, thyme, chamomile, and
jasmine essential oils was significantly stronger than that of the other six
essential oils,” explains the study. “The fractions of viable cells were
reduced to 5.31%, 3.47%, 6.93% and 4.34%, respectively.”
Complimenting the findings of this research, another study published in the journal Industrial Crops and
Products found that chamomile oil harnesses powerful antioxidant
properties. The research, evaluating 11 essential oils including lavender,
thyme, winter savory, rosemary, sage, peppermint, French tarragon, bitter, and
sweet fennel, found Roman chamomile to have the highest antioxidant activity.
“Thyme and winter savory oils exhibited the greatest inhibition against
the growth of all the tested organisms possibly due to the high content of
thymol and carvacrol respectively,” states the study’s abstract.
