25 Cancer Stem Cell Killing Foods Smarter Than Chemo & Radiotherapy?

By Dr Frank Yap, MD -
Cancer stem cells (CSCs) first identified in acute myeloid leukemia (AML) by Bonnet and Dick in 1997 are shown to be similar to normal stem cells which have the capability of self-renewal and differentiation into other cell types (Ailles and Weissman, 2007).

Further studies have proved that CSCs have a leading role on resistance to cancer therapies such as chemotherapy and radiation therapy and in addition to that, they have an increased metastatic potential which is a considerable problem to handle (Clevers, 2011).

There are thousands of natural compounds that have been studied with demonstrable anti-cancer activity, but only a small subset of these have been proven to target and kill the cancer stem cells which lie at the root of cancer malignancy. 

Note: When interpreting scientific studies, let’s remember that cell culture and in vitro results are trumped by mouse and in vivo results. Mouse results are trumped by human results. Case studies & small human trial results are trumped by double-blind placebo controlled ones.

A study published in the journal Anticancer Research (2015) titled, "Natural Products That Target Cancer Stem Cells," has identified this special category of cancer killers by listing the top 25 natural substances in this category. They are listed here below, along with some of their commonly recognizable dietary sources:

  1. Epigallocatechin-3-gallate (EGCG) - Green Tea

  2. 6-Gingerol - Ginger

  3. β-Carotene - Carrot, Leafy Greens

  4. Baicalein - Chinese Skullcap

  5. Curcumin - Turmeric

  6. Cyclopamine - Corn Lilly [we do not suggest consuming this plant; this simply illustrates that natural components that kill cancer stem cells do exist]

  7. Delphinidin - Blueberry, raspberrry

  8. Flavonoids (Genistein) - Soy, red clover, coffee

  9. Gossypol - Cottonseed [we do not suggest consuming this plant; this simply illustrates that natural components that kill cancer stem cells do exist]

  10. Guggulsterone - Commiphora (myrrh tree)

  11. Isothiocyanates - Cruciferous vegetables

  12. Linalool - Mint

  13. Lycopene - Grapefruit, tomato

  14. Parthenolide - Feverfew

  15. Perylill alcohol - Mint, cherry, lavender

  16. Piperine - Black pepper

  17. Platycodon saponin - Platycodon grandiflorum

  18. Psoralidin - Psoralea corylilyfolia

  19. Quercetin - Capers, onion

  20. Resveratrol - Grapes, plums, berries

  21. Salinomycin - Streptomyces albus

  22. Silibinin - Milk Thistle

  23. Ursolic acid - Thyme, basil, oregano

  24. Vitamin D3 - Fish, egg yolk, beef, cod liver oil

  25. Withaferin A - Withania somnifera (ashwaganda)







Why are these substances so important?

The primary reason why conventional chemotherapy and radiotherapy have failed to produce any significant improvements in cancer survival rates is because cancer stem cells are resistant to these interventions.

10 Best Cosmeceutical Ingredients of 2024

By Dr Frank Yap, MD -
Image
A cosmeceutical is essentially a skincare product that contains a biologically active compound that is thought to have pharmaceutical effects on the skin. Both pharmaceutical and cosmeceutical grade skin care products actively effect skin at a cellular level, whereas cosmetic products have a shorter-term effect. They are usually used by doctors to restore pH, remove pigmentation, or restore the skin barrier. Cosmeceuticals must scientifically verify the claims stated on their packaging; as it is accepted that these formulations are backed by science, clinical studies, and rigorous testing. The main areas of concerns that these formulations address are ageing skin, sensitive/sensitized skin, sun damaged skin, acne/oily skin, loss of tone and elasticity, as well as superficial lines & wrinkles to encourage rapid cellular turnover that will renew and re-texturize the skin. Peptides composed of chains of amino acids give proteins their structure, and transport nutrients and signal mess...

Exosomes, neurocosmetics, and supercharged actives are the most innovative — and sometimes the most controversial — skin-care trends poised to revolutionize beauty in the next few years. We pored over the data and talked with experts to give you a snapshot of the top skin-care trends of 2024. Regenerative medicine will inspire your skin care.

As with so many skin-care trends that have come before, this one is rooted in medicine — in this case, regenerative medicine, which is centered on developing and applying therapies to help the body heal itself. For example, stem cells — those biological blank slates that can turn into new skin, cartilage, or bone — are currently used in oncology to help the body produce new blood cells after high doses of chemotherapy. Again, this may sound like sci-fi (a t...

If you have been diagnosed with cancer, or have a loved one that is suffering from cancer, chances are you have heard about the Joe Tippens Cancer Protocol. The Fenbendazole Cancer Protocol has been gaining rapid interest over the past years following some fenbendazole advanced cancer success stories. Joe Tippens founded the protocol after he was told a story about a scientist at Merck Animal Health that had been performing cancer research on mice. The research included injecting different types of cancers into different mice body parts. The scientists discovered, through trial and error, a product in their canine product line, fenbendazole, that was batting 1.000 in killing these different cancers in the mice. The scientist was later diagnosed with stage 4 brain cancer and was given a grim prognosis of only three months to live. She decided to try the fenbendazole, and after six weeks, showed a clean scan.
