18 NATURAL AROMATASE INHIBITORS

The number one topic in breast cancer communities, and the thing I get asked about most often, is definitely about natural aromatase inhibitors.  People are suffering from the effects of hormone blocking drugs like Tamoxifen, Raloxifene, Faslodex.  The list of side effects these drugs are capable of producing is seemingly endless and as a breast cancer coach I hear it all and have a lot of sympathy.

It’s a subject near and dear to our hearts and we can spend plenty of time trying to dig up research on new natural alternatives – I know I do because I chose not to take Tamoxifen, much to my oncologist’s annoyance.  I just wasn’t willing to risk the side effects, such as cardiotoxicity and blood clots, etc. 

Update: I recently wrote an article sharing why I chose not to (in case you’re interested): Why I Chose Against Hormone Blocking Drugs

It worries me that the side effects of these drugs can be so debilitating and disruptive to quality of life.  More than that, I know quite a few who were on AIs for the requisite period of time (usually 5 years) and suffered recurrences anyway.  That indicates to me these drugs aren’t working as well as they are meant to.

A Good Article

While doing some research today, I came across a lengthy article, “Natural Products as Aromatase Inhibitors” at the NIH website.  Click here to view that article, but be warned, it will do your head in, unless you are a doctor, researcher or medical professional! 

I will attempt to boil it all down into layman’s language for you – you can read for yourself all of the reasons why AIs are prescribed, how they work in breast cancer, and how scientists are actively researching many natural products to discover which ones can be utilized to help breast cancer patients.  I know what you are really after — the list of natural things that exhibit AI activity. 

18 Natural Aromatase Inhibitors

  1. Dioon Spinulosum – or gum palm, a cycad which grows in Veracruz and Oaxaca, Mexico
  2. Encephalartos ferox – also a cycad which grows mainly in Africa
  3. Riedelia – a genus of plants in the Zingiberaceae family, comprises approximately 75 species that are distributed among New Guinea and the Maluku and Solomon Islands

  9. Five red wine varieties, the most active being Cabernet Sauvignon from Tanglewood (France), the other mentioned was Pinot noir from Hacienda (Sonoma, CA)
  10. Brassaiopsis glomerulata – a deciduous tree found in North Vietnam

  14. Scutellaria barbata – a plant used in traditional Chinese medicine, other names include ban zhi lian’, scullcap or skullcap, it grows in Korea and southern China
  15. Camellia sinensis – also known as green tea
  16. Vitis L. sp – also known as grape seed extract, the report cited a study where a water extract of grape seed extract was utilized and it had AI activity
  17. Agaricus bisporus – also known as white button mushrooms
  18. Trifolium pratense L. – also known as red clover flowers.  There is a lot of misinformation out there about red clover, please read my article Red Clover Controversy – Safe For Breast Cancer Or Not?

The article also mentioned that coffee, cocoa, collards, stout beer, tomato leaves and even cigarette smoke (!) strongly inhibited aromatase using a microsomal assay.  I don’t know about you but I’m not eating tomato leaves or breathing in cigarette smoke intentionally!

Many of the above listed things are not currently being produced as natural supplements, however some are.  I would suggest you print out this list and take it to your naturopath to see which ones would be safe for you to use.  Some of the listed items will be easily available (like #9, #15, #16, #17 #18) and you could easily incorporate them into your diet. 

Something not listed is selenium, we do have research indicating that it acts as a natural aromatase inhibitor, see my article  Why Iodine and Selenium Are Useful For Breast Cancer.

The above list is not exhaustive – the report did also discuss 125 flavonoids, 36 terpenoids, 19 peptides, 18 lignans, 16 xanthones, 15 fatty acids, 10 alkaloids, and 43 miscellaneous compounds having been evaluated but there was not sufficient information for me to feel it was worth listing them all.

Unfortunately, there is no information on dosages for any of the above nutrients, more information is clearly needed.

Just Remember Estrogen Is Not The Only Factor Involved In Breast Cancer

The important thing I would like you to take away from all of this is that we can drive ourselves crazy looking for the tiniest things that will give us an edge over this disease.  I hope you don’t get bogged down in this. Please remember, estrogen is not the only factor involved in breast cancer.  An overall anti-cancer strategy is to eat a healthy diet full of super foods, build a super-strong immune system (see my page on how to do that), include some of the things from this list where they make sense (and are available) to you, limit your exposure to toxic skin care products, get plenty of exercise and keep your stress levels down through the use of meditation or prayer. 

I am continually on the outlook for natural aromatase inhibitors (AIs) and have written a few articles you may find useful: The Down & Dirty on Aromatase Inhibitors for Breast Cancer Treatment, Acupuncture: How It Helps With Cancer Treatments , Aromatase Inhbitors Natural vs Toxic, Researchers Discover Mushrooms Could Be Potent Natural Aromatase Inhibitors, Why Vitamin D is So Important for Breast Health and Is Chrysin a Good Natural Aromatase Inhibitor?
