Supplements and Cancer: What Works

What Really Works? Part One
Sunday, 09 January 2011, from Ralph Moss, PhD

Coriolus versicolor (Turkey tail) mushroom

One of the hardest questions to answer is which, out of the many supplements really benefits cancer patients? There are many self-interested statements of benefit, but an inadequate amount of objective research on what is effective and what is not.

I therefore want to call your attention to an interesting article from Memorial Sloan-Kettering Cancer Center (MSKCC). It compared the following seven botanical extracts and fractions:

(1) H-48 (a Chinese mixture of herbs)

Coriolus vesicolor,  or its derivatives: purified polysaccharide-K (PSK) or purified polysaccharide-peptide (PSP)

Maitake mushroom extract


Astragalus root

(6) The yellow spice turmeric; and

(7) β-glucan derived from yeast.

All of these are popular supplements used by cancer patients. The MSKCC authors looked at the ability of these substances to induce immune reactions in laboratory mice. Specifics on these products, and how they were tested, are given in the reference below. (The full paper is available for free, and readers should consult that text for details).

The bottom line of the study was this:

Consistently significant activity was seen with four of the preparations:

(1) Coriolus mushroom extracts (especially PSK);

(2) Alcohol extract of astragalus

(3) yeast β-glucan;
and (to a lesser extent)

(4) Maitake mushrooms.

Little or no adjuvant activity was demonstrated with H48, Echinacea extracts or a water-based extract of astragalus. The results with turmeric were mixed (but the New Chapter brand of turmeric was active.)

Coriolus versicolor
(also called Trametes versicolor or Turkey tail mushroom) is available from a number of sources. I will have more to say about Astragalus in a future blog entry.

That's always the question of other people. I think it's the vitamin rich in antioxidants that can help cure cancer.

I think the first question to address when talking about supplements and cancer is what effect anti-oxidant supplementation has on chemotherapy and radiation?

Dr. Keith Block performs a thorough study of the issue above.

Thank you for the comment. Dr Lad from U Colorado has been studying this issue for years. We know that supplements truly do have a proven track record in cancer prevention, therapy and recovery. We hops mainstream medicine wil eventually wake up to this fact. Afterall Dr Kelley cured liver and pancreatic cancer this way in the early 60s.

I'm not really a fanatic about in depth topics about health, but I sure did learned something from reading this.

Don't just settle for well-advertised supplements, but choose the right one for your health.
