Bulbous fennel with its characteristic licorice and anise-like aroma has long been considered a potent nutraceutical even in ancient cultures. It has been hailed as having anti-oxidant, anti-inflammatory, anti-proliferative and anti-tumor potentialities, and should therefore feature regularly in your anti-cancer kitchen.

The Research

Research has been conducted into trying to reduce the high mortality rate associated with some prostate cancers. It was found that anethole, a major constituent of fennel essential oil, inhibited the growth and migration in certain prostate cancer cells (PC-3), as well as suppressing their stem cell growth. It was also shown to downregulate the activation of NF-kappa- genes, a cell-to-cell signaling molecule considered cancer’s master switch, capable of turning on inflammation and altering genes.

One study looked at possibly reducing the amount of the chemotherapy drug Cisplatin by combining it with a fennel extract, hoping both applied together would result in the same cervical cancer cell growth reduction. This would enable a lower dose of cisplatin, thus reducing the adverse side effects of this potent drug. Results confirmed their findings.

Another study investigated whether the use of extracted essential oils including from fennel, acted as natural anti-oxidants to help reduce the liver damaging effects of the chemotherapy drug cyclophosphamide (CP). They also found that these oils were able to restore the functioning of the body’s own anti-oxidants to their normal levels after undergoing changes due to CP.


Fennel is very soothing to the stomach lining and thus an excellent addition to a gut healing protocol when undergoing, and recovering from, chemotherapy treatments which notoriously destroy the protective lining of the gut mucosa. It also helps reduce muscle spasms and expels excess gas.

Fennel is closely related with celery, and their texture raw is almost the same. Here are a few ways to serve this delectable bulb:

• Raw in salads, it makes an excellent companion to almost any salad ingredient
• Sautéed to accompany a stir fry or fish
• Sliced and fermented as a condiment to satisfy your daily fermented food intake
• Excellent additions to raw juices and smoothies
• Served raw with hummus or a cultured yoghurt dip

    Is the ordinary strand fennel safe?
