Our Gerson Guide to Juicers explains what juicers are appropriate for the Gerson Therapy, for cancer and for non-malignant conditions.

Gerson patients juice all day, every day. An average Gerson cancer patient drinks up to 13 glasses of fresh, organic, raw juices daily—the equivalent of 15 pounds of produce in liquid form! Since one could not possibly digest that much produce in one day, it is necessary to remove all the bulk and fiber from the fruits and vegetables so that it is quickly and easily digested, while retaining the maximum amount of nutrients and enzymes. The Gerson juices are completely smooth and pulp-free, for optimal digestion and nutrient absorption. Not every juicer has the mechanical capability to accomplish this task, which is why the Gerson Therapy requires a very specific type of juicer.

Juicers for Cancer

The Gerson Therapy for cancer requires a two-step machine, which has two components: a grinder and a hydraulic press.

The first component is a grinder, which grinds the vegetable into a fine, moist pulp. The second is a hydraulic press, which extracts the juice of the vegetable from the pulp by pressing it under high pressure. Dr. Gerson found that grinding the produce before pressing was essential. The pulp of the different fruits and vegetables should be mixed and pressed together, because the malic acid contained in the apples allows the other vegetables to release more minerals.

A two-step juicer is necessary for cancer treatment because in a one-step masticating juicer each item is ground and pressed separately. During the process of grinding and pressing in a two-step juicer, the produce is not subjected to heat or electricity, so the fresh, healing enzymes in the raw fruits and vegetables are preserved in the juices. In our decades of experience, we have found that these are the most effective and efficient juicers, and best suited for providing the optimal nutrition for the Gerson Therapy.

Research in this area, although limited, indicates that juice produced by the grinder/press can be as much as 50 percent higher in certain essential nutrients, and will produce 25 to 50% more than other juicers from the same amount of raw produce.

Though it is a major investment, bear in mind that a powerful juicer with a hydraulic press produces more juice, while using less produce, than other types of juicers. After the produce has gone through the press, the leftover pulp is completely dry, as all the essential juices and nutrients have been thoroughly extracted. In the long run, given the large quantities of produce used by a Gerson patient, these two-step juicers are actually cost-effective.

We have found three juicers that fit this criteria for cancer:
  • The Norwalk Juicer
  • PURE Juicer
  • The Champion Juicer (with homogenizing nozzle) and separate hydraulic press

The Norwalk

The Norwalk Juicer was developed by Dr. Norman Walker when he opened the Norwalk Laboratories of Nutritional Chemistry and Scientific Research in 1910. Dr. Walker was a contemporary of Dr. Gerson and is regarded as one of the front-running advocates of nutrition for overall wellness and treatment of disease. The Norwalk was the only juicer of its kind for many, many years. We have had the most experience and success with the Norwalk Juicer.

PURE Juicer

The PURE Juicer is the newest two-step juicer on the market to meet Dr. Gerson’s requirements for a separate grinder and press, and includes several unique features. Patients have been using the PURE Juicer since it’s 2016 debut with positive feedback as the PURE Juicer team continue to enhance its features and accessibility.

Champion Juicer with Separate Hydraulic Press

The next-best alternative is to buy the Champion juicer, but only use it as a grinder, and buy a separate hydraulic press to extract the juice from the pulp. 

The Champion alone is not ideal for the Gerson Therapy for cancer, because it is a standard masticating juicer which grinds and presses the produce in one step, and does not extract enough juice from the pulp. When using a Champion juicer for the Gerson Therapy, a special homogenizing nozzle is used to grind only. This way, the Champion simply grinds the produce into a fine pulp, which you can then place into the hydraulic press to extract the juice.

Although this is a cost-effective alternative, bear in mind that because the Champion/press combo is two machines, more work is required. For each juice that you prepare, you must use (and clean) two different machines, which is more time-consuming.  When you are preparing 13 juices every day, this is a major consideration!

Juice Press Factory sells the Champion juicer and hydraulic press combo for Gerson patients, while used Champions are available.

Juicers for Treating Non-Malignant Conditions

For patients doing the Gerson Therapy for non-malignant conditions, or healthy people juicing to enhance their health, it is not as strictly necessary to use a two-step juicer, though it is still recommended.

Masticating juicers are acceptable alternatives for non-cancer patients doing the Gerson Therapy, as they extract a sufficient amount of juice, and preserve enzyme activity. There are many brands of masticating and twin-gear juicers out there.

A few that our patients have used which are suitable for the Gerson Therapy for non-malignant conditions include:

  • The Champion (pictured at right)
  • Angel Juicer
  • Green Star
  • Green Power
  • Solo Star
  • Hurom Slow Juicer
  • Omega Juicers (masticating models only)


Citrus Juicers

Gerson patients often drink a glass of citrus juice with their breakfast; either orange juice or grapefruit juice.* Just like the other Gerson juices, though, the citrus juices don’t come in a carton! The citrus juices also must be raw and freshly squeezed. Unlike the other juices for the Gerson Therapy, the citrus juice should not be prepared in your two-step juice machine. You need to avoid juicing the skin of the fruit, because it contains aromatic oils which can interfere with the Gerson Therapy. Instead, the citrus juices are made using an electric or manual reamer-style citrus juicer.

Patients with collagen diseases (i.e. rheumatoid arthritis, SLE) should not drink citrus juice.

Unsuitable Juicers


Centrifugal Juicers

In our experience, centrifugal juicers are wholly incompatible with the Gerson Therapy. Though they are often the most popular and least expensive juicers on the market, we do not recommend using a centrifugal juicer for any condition. Dr. Gerson found that in his many years of clinical experience, patients who used centrifugal juicers did not have success with the Therapy. Centrifugal juicers are problematic for several reasons. The centrifugal force throws the pulp against a basket screen through which the juice is strained, while the pulp remains. Dr. Gerson said of centrifugal juicers:

“When the grinding wheel rotates against a resistance with insufficient access of air, positive electricity is produced and induces negative electricity on the surrounding wall. The exchange of positive and negative ions kills the oxidizing enzymes and renders the juice deficient.” – Dr. Max Gerson, MD

Centrifugal juicers expose the juice to heat and oxygen, killing off the essential healing enzymes in the juice. These juicers have difficulty in juicing leafy greens, as is required for the Gerson Therapy green juice. Without the pressing action to extract the juice, many minerals and phytochemicals remain in the pulp, so the juice rendered is less rich in healing nutrients than juice from grinder/press or masticating juicers.

Centrifugal force is less effective in extracting juice than the pressing action of other juicers, meaning that more produce is required to make less juice. When a patient is making 13 juices per day, this alone is a major consideration. An inefficient juicer may be cheaper in the short term, but will be more expensive in the long run, as it necessitates spending more money on produce.

The following centrifugal juicers are not recommended for the Gerson Therapy:

  • Jack LaLanne’s Power Juicer
  • Breville Juice Fountain
  • Omega (centrifugal models)
  • Hamilton Beach Juice Extractor
  • Black & Decker Juice Extractor

Blenders and Liquefiers

Blenders, such as the Vita-Mix and the Blendtec, are not really juicers at all. They make smoothies, rather than juices. They chop the produce into a fine pulp but have no mechanism by which to extract the juice. Since there is no reduction of bulk with a liquefier, to derive the nutrients equivalent to those in thirteen 8oz glasses of juice, a patient would have to ingest an alarming quantity of produce: six pounds of carrots, eight pounds of apples, and four heads of lettuce every day! And that’s in addition to three regular meals. It is simply not possible for a patient to prepare and consume all the necessary juices for the Gerson Therapy using a blender.

Wheatgrass Juicers

Wheatgrass juicers are small specialized machines designed specifically to extract the chlorophyll-rich juice of wheatgrass. We generally do not use wheatgrass on the Gerson Therapy, as most patients find it to be extremely harsh on the stomach and because the desirable components in wheatgrass are also found in the Gerson green juice.

Why Don’t We Recommend Any Other Types of Juicers?

We can only recommend juicers that we personally have experience with, and that have been used to successfully treat illnesses with the Gerson Therapy. We do not have enough experience with other juicers to be able to recommend them. While it is certainly possible that there are other effective juicers on the market, we cannot recommend juicers that we have not tried ourselves. We do have anecdotal evidence that indicates that other juicers are not as effective. Some patients who have tried the therapy using other juicers did not have much success, but when they switched to a grind and press juicer they began to see rapid improvements in their condition. For optimal results on the Gerson Therapy, using a proper juicer is crucial.

Where to Purchase a Juicer

Please see our Gerson Supplies page to find contact information for the companies that sell the Norwalk, the Champion, the hydraulic juice press, and juice cloths. You may also be able to find a used juicer through one of the following sources: Craigslist,, or the Penny Saver. (Please note, though, that used juicers are typically not covered by warranty, and we encourage prospective buyers to inquire with the seller to make sure that it works and is in good condition).
