10 Best Cancer Killing Phytonutrients To Eat

Thirty years of research reveals 10 of the best food phytonutrients to ingest to protect against and even treat the root cause of most cancers. 

A new medical model is fast emerging in line with ancient wisdom: one that aims to strike to the root cause of disease and resolve it permanently, and which some call "functional medicine." In cancer treatment, this highly rational approach involves targeting the cancer stem cells (CSCs) at the root of cancer malignancy. Because we now know that CSCs are resistant to chemotherapy and radiation treatment, and may even increase in number and invasveness when exposed to these outdated therapies, it is no longer ethical to continue with the conventional oncologist's "standard of care." Clearly, unless a cancer treatment is capable of selectively killing and/or inducing suicide programs (apoptosis) within cancer cells without harming non-cancerous cells, it is not going to produce a cure.  

In light of this, we are excited to report on a new review published in the International Journal of Molecular Sciences titled, "Phytochemicals as Innovative Therapeutic Tools against Cancer Stem Cells," which evaluated the evidence for what natural compounds within various foods and spices make for the most compelling treatments for targeting CSCs.

According to the review of 30 years worth of literature on the topic, the following 10 natural substances have been demonstrated to be the most effective chemopreventive dietary agents against CSCs:

  1. Epigallocatechin-3-gallate (EGCG)green tea extract

  2. Curcumin: The primary polyphenol in turmeric root 

  3. ResveratrolA phytochemical found in grapes, peanuts, Japanese knotweed

  4. Lycopene: A red carotenoid found in watermelon, pink grapefruit, and tomatoes

  5. Pomegranate extracts

  6. Luteolin: A flavonoid found in peppers and various green vegetables

  7. Genistein: A phytochemical found in soy, red clover, and coffee

  8. Piperine: A phytochemicals found in black pepper

  9. β-caroteneAn orange carotenoid found in various vegetables

  10. Sulforaphane: A sulfurous phytochemical found in Cruciferous vegetables

The researchers described the discovery that phytochemicals can selectively target CSCs as "a milestone in the improvement of cancer treatment because the synthetic anticancer drugs that are currently used are often highly toxic for healthy organs and weakens the patient's immune system."


They also pointed out that the phytochemicals or extracts identified above, due to their "low levels of toxicity for normal cells," can be used in combination with other phytochemicals, "yielding powerful synergistic effects."

They identified several key areas of focus for the future:

  • Finding a way to combine these compounds into "very active cocktails of phytochemicals" to address the multiple areas of treatment resistance often found in CSCs.

  • Compare the effects of natural phytochemicals with synthetic drugs, the latter of which they anticipate will be found to be less efficient.

  • Further research should be performed on CSCs to better understand the signaling pathways that govern their self-renewal and survival.

The authors concluded, "[T]he use of phytochemicals may be a true therapeutic strategy for eradicating cancer through the elimination of CSCs."

If you have followed, you know cover the complex terrain of modern cancer treatment and its failures in various exposes on cancer overdiagnosis, the misunderstood nature of cancer, the reality of chemo and radiation resistance, the sorcerer-like power that doctors have over the health destiny of their patients, and the corrupt pharmaceutically-driven medical system that sacrifices ethics for profit. It is clear that while this is a harrowing task and topic, often fraught with darkness, the discovery that natural substances are superior to highly toxic chemotherapy and radiation in selectively killing the root cause of cancer is extremely promising and should help to usher in a new era of cancer prevention and treatment that looks at our dietary decisions as the most important factor in our health destiny.

Cannabis is not on this list?

Cannabis therapeutics is personalized medicine. The right treatment regimen depends on the person and condition being treated. For maximum therapeutic benefit, choose cannabis products that include both cannabidiol (CBD), a non-intoxicating compound, and tetrahydrocannabinol (THC), the psychoactive component of cannabis. CBD and THC interact to enhance each other’s therapeutic effects. They work best together.

“I was a patient that really could not be treated by western medicine. I learned to walk and talk again three different times, but I never saw any improvement in my condition. It was an endless cycle, until, of course, I was introduced to cannabis!” –Debbie Wilson-

DR Cristina Sanchez PhD talks about THC/CBD ratios for various types of cancer

MMJ may not be the complete answer that is needed by the general public. Sprouted cannabis seeds may be a missing link. Why you might ask? This is a complicated subject that may be answered by simply referring you to a few specific articles  that we should all discuss in great detail.
The "Nutritional Analysis of Hempseed Sprouts" reveals some details that need further investigation and may open the pathway to an entirely new and useful industry for people on a global scale
Cannabis - whether Sativa, Indica, Ruderalis, male, female, hermaphrodite, wild, bred for fiber, seeds or medicinal resin - is a vegetable with every dietary essential we can't synthesize: Essential Amino Acids, Essential Fatty Acids, Essential Cannabinoid acids and hundreds of anti-Cancer compounds.
"The Hemp plant is actually an excellent plant because the THC content can be low, that's if you're treating a condition for which appears CBD food supplement is in order. . . The plants we're using in Luxembourg have only 1% CBD, a 1% CBD plant is providing you with 19 times more CBD per pound than Oranges provide you of vitamin C. A 1% is an excellent source, you can make tremendous concentrates you can eat the plant raw - and the absence of the THC - you can heat Hemp, which you can't do with other strains because the THC acid comes out and you end up with a psycho-toxic substance," says Dr. William Courtney
We need to enact laws that allow people to grow hemp and/or cannabis for the harvesting of seeds on a national scale. The seeds would then be used to grow sprouts. The additional health benefits derived from hemp/cannabis sprouts simply will revolutionize a new industry. A few states have already passed the laws that allow seed production. News laws are needed on a national scale. So, we need a leader that understands God's "PLANT OF RENOWN" and how to use it.
Cannabis suppositories bypass the liver and are absorbed into the bloodstream quickly by thousands of nerve endings in the colon and rectum walls. They do not give you the same euphoria as is experienced when you inhale or eat your cannabis and they provide hours of relief for physical pain. This makes it an effective delivery method for people who may not be able to eat, inhale, or are suffering from cramping, inflammation, vomiting, body pain, or any number of ailments that happen below the belt.
There's more than one way to cure cancer with cannabis. "We started using the "Backdoor Method'' on the 20th May 2014 as I was having trouble getting up to the 1ml of Cannabis Oil orally, which is recommended for aggressive cancers. We started mixing half a ml of organic coconut oil with a half a ml of cannabis oil to put it in suppositories but this wasted a lot of our oil & was messy. So we decided to draw it up with a 1ml syringe & put it straight in. Up & in."
Her cannabis treatment started in May 20, 2014, and her cancer was gone by Sept. 3, 2014. Within three months, her back door cannabis oil treatment cured her stage IV lung cancer! Interestingly, Chinese medicine connects the bowels to the lungs energetically. It's a pathway in that system. And ozone therapy is commonly injected anally to treat lung cancer patients.
As well, it has been suggested to me by an expert in Colorado that making Hash Oil (Rick Simpsons Oil, RSHO, etc.) is not necessary. Rather, making "Cannabis Paste" is his preferred method.  
The anticancer properties of cannabinoids have been recognized for some time
Please note: RAW cannabis may be 200 times more effective and reduce the side effects of MMJ almost completely...

1. The type of cannabis and/or hemp and the process used to deliver the medicine depends GREATLY on what you are trying to accomplish.
2. CBD and THC content should be based upon many factors that are best addressed with details about the individual involved, i.e., has cancer, mental issues, etc. Often, a doctor experienced in the art is needed as well.
3. Please consider the following carefully, as there has been some concern about heavy metals and other contaminants in products such as Cibdex and further concerns that are detailed below. Finding a reputable person that does sufficient Product Lab Testing for active content of THC/CBD and other contaminants is a widespread problem in the MMJ Industry.* Rick Simpson Oil making demonstration
Having said that, I can give you some general information that might be helpful. Understanding the whole picture is going to be a key in solving problems. Grain consumption, nightshades and modern food is a major concern. As well as what might be missing. If something is not working, try something new! Too many people expect instant results; rather than the 3 weeks, or 3 months it takes to measure. In some cases, years.
*CBD oil can be obtained at with percentages that range from 16 to 18 percent. Other forms of CBD may be obtained at as well.
P.S. THC and CBD each have their own special purpose. What you use depends greatly on what you are tying to accomplish. Perhaps the following information will be useful.
Dr. Courtney, "my youngest patient is 8 months old, and had a very massive centrally located inoperable brain tumor... within two months there was a dramatic reduction... the tumor was remarkably reduced after eight months of treatment." at
PLEASE NOTE: A new paradigm in health is obtained by consuming the juice of young-RAW-cannabis as a food source. Leaf introduces Dr. William Courtney and Kristen Peskuski of Cannabis International; along with the people involved in researching, promoting, regulating and benefiting from raw cannabis. It is unfortunate that it requires about 30 plants over the course of a year...
The Power of RAW Cannabis is obvious and the "miracles" never cease

Gary Wenk, Ph.D, professor of neuroscience, immunology and medical genetics at Ohio State University, told Time Magazine:
“I’ve been trying to find a drug that will reduce brain inflammation and restore cognitive function in rats for over 25 years; cannabinoids are the first and only class of drugs that have ever been effective.”

Dr. David Allen has good reason to think, “Cannabidiol (CBD), may offer control of the immune system and in turn provide protection from viral infections. Cannabis has already been recognized to inhibit fungus and bacteria and can be considered a new class of antimicrobial because of the different mechanism of action from other antimicrobials.”
Recently, it was discovered that the stalks of Cannabis (hemp) are far more complex than previously known. A large set of galactans, mannans, xylans, and glucans, as well as raffinose-series disaccharides exist. Putative arabinogalactan proteins and lipid transfer proteins were among the most highly enriched transcripts in various stem segments.

William Courtney, MD, “The following is provided as a pre-publication excerpt of our book reviewing the general principles on the use of high dose, non-psychoactive, dietary cannabis.”
Overview on use of Raw Cannabis
Please review the patents, articles, interviews & internet resources at
The use of the raw plant includes the acid cannabinoids; CBDA, THCA, CBGA, CBCA. The acid cannabinoids, CBDA and CBGA are now known to act at GPR55 as potent antagonists of that pro-inflammatory receptor. The acid cannabinoids are 2-4 fold more effective than the neutral cannabinoids which have been the exclusive focus of study for the last 30 years. The neutral cannabinoids, CBD, THC, CBG, CBC … are functionally synthetic molecules made by application of heat to alter the Phytocannabinoids.  The specific ratio of cannabinoids is an area in need of additional research.  Consumption of the whole mature raw flower / bud and leaf is the best current thought. The amount per day is dependent upon the weight-to-weight cannabinoid content analysis of that specific plant as there is dramatic variation between particular plants of the same name.
If analysis is not available, assume high THC concentration in the 12% to 21% w/w range. In general CBD is usually less than 1% w/w. Another way of describing the relative amounts of THC to CBD is cannabinoid content. For the vast majority of strains in California the ratio per 100 grams of cannabinoid, 90-95 grams are THC while the amount of CBD/100gm runs 1-3 grams. Sadly the other 78 cannabinoids share the remaining 2 grams. Note that W/W is the amount of CBD per unit weight of cannabis where cannabinoid content is an estimate of the relative amount of THC to CBD per 100 gm of cannabinoid extract from a particular strain.
As we go forward the hunt is on for broad profile plants such as might have been found after 34 million years of evolution but before the last 10,000 years of selective breeding that has created plants in which 95% of the all the cannabinoids present are THC.  While drying and aging can convert THCA into THC, heating is quick and complete. Once THCA is decarboxylated into THC, you create a very potent CB1 agonist that dose restricts the use of the plant from 1,000 mg to 10 mg!  We currently believe the dietary dose of the cannabinoid acids to be 500 to 1,000 mg/day range, taken in divided doses, see the medicinal acidic cannabinoids patent at patent page.  The FDA has approved of CBD as an Investigative New Drug / IND at 600 mg in divided doses. The DHHS patent, on cannabinoids and Neuroprotectants, gives an ‘Effective oral human dosage schedule of 1-40 mg/kg for example 5-20 and in particular 20 mg/kg body weight.’ A copy of that patent is number 1 on the patent page at
You might start out at a couple of grams of mature bud / flower and slowly increase to 14 grams or 1/2 ounce wet weight mature bud that is still living or raw. In addition to the raw bud use 30 to 300 leaves per day in accordance to the amount of plant available on a daily basis. It is best to juice the leaves to decrease bulk but it is best to blend the flower which results in less waste of that valuable part of the plant. Flavor management is very important for compliance. The juiced leaf and blended flower is combined with hemp milk / keifer / yogurt into a smoothie or combined with fresh vegetable or fruit juices. Organic produce without the fungicides, herbicides and pesticides are important if available.
The smoothie / juice with its phyto-cannabinoids / terpenes / flavinoids are best taken in divided doses due to their rapid clearance i.e. the cannabinoids clear in about 50 minutes after absorption from the intestine is complete. If the final amount is 10 ounces, then divide into five 2-ounce doses and take every 4 hours. Keep on ice. Shake before using to mix the fatty acids with the water portion of the juice.  For serious illnesses, try for 6 doses a day, that is leave one dose in the refrigerator for consumption if one gets up to use the restroom at night.
Replace high THC plants with plants of increased CBD content and ideally with plants providing specific ratios of CBDA to THCA indicated for the specific medical condition.
DO NOT HEAT as that will convert any available THCA into THC.
The THC dose, for those that are comfortable with THC, is 10-15 mg. If you are blending a mature bud into a glass of juice it could and should have 5-600 mg of THCA and 5-600 mg of CBDA if the plant is a 1:1 plant such as the original Cannatonic 6.9%w/w CBD to 6.2% w/w THC or a tested strain of Harlequin, which range from 4%/4% to 8%/8% CBD/THC.  If that juice is accidentally heated by placing the ‘vegetable’ juice into a vegetable soup, it will create a very psychotoxic dose of THC.


AVOID ACCIDENTS, Do not allow the person caring for your cat in your absence, to put your ‘vegetable’ juice into a vegetable soup or stew. The outcome would be very psychotoxic!
Cannabis is the poster child for raw food, heating not only reduces the efficacy of some of the components, i.e. converts CBDA into CBD with the resultant loss of anti-inflammatory activity at the orphan receptor (GPR 55), but most importantly converts THCA into poison, when inadvertently consumed at a 600 mg dose rather than the tolerable 10 mg dose.
Reiterating to a fault, if you are consuming 600 mg of a 1:1 plant, you are consuming not only 600 mg of CBDA but also 600mg of THCA, upon heating the THCA turns in to approximately 580mg of THC when the tolerable dose is 10 mg! That would be like consuming 58 brownies when you can only tolerate 1!
If you find a source of cannatonic seeds beware that the cannatonic feminized seeds can vary widely from the original plant. Recent HPLC testing showed an expression of CBDA from 22% w/w to <1%CBDA and concurrently THCA contents ranged from 1% w/w to 30 % w/w.   This marked divergence mandates testing of the plant while keeping back living clones in case you locate the desired cannabinoid ratio.  See the Brian Whittle patent, Table 2 to develop an appreciation of the impact of cannabinoid ratios on diverse medical
conditions. This list is growing.
If you go forward, please document; strain, cannabinoid test results, dosing and monitor symptoms with a standardized rating scale on a very regular basis. This will shed some light for those that follow you.
You have my most sincere well wishes.
