Krebiozen

It is claimed that krebiozen, originally called substance X, came from horses inoculated with Actinomyces bovis by Dr. Stevan Durovic. Durovic claimed that krebiozen had been useful in the treatment of spontaneous cancer, mainly in cats and dogs. It is unclear what kreboizin really contained; in some cases it was found to be creatine monohydrate and in other cases it contained mineral oil and l-methylhydantoin, a product of heating creatine monohydrate.

BACKGROUND

It is claimed that krebiozen, originally called substance X, came from horses inoculated with Actinomyces bovis by Dr. Stevan Durovic. Durovic claimed that krebiozen had been useful in the treatment of spontaneous cancer, mainly in cats and dogs. It is unclear what kreboizin really contained; in some cases it was found to be creatine monohydrate and in other cases it contained mineral oil and l-methylhydantoin, a product of heating creatine monohydrate.

Several studies have failed to show beneficial results from kreboizen. Reports published by the Krebiozen Foundation found improvement in cancer patients, but these results were disproven by the U.S. Food and Drug Administration (FDA) and the National Cancer Institute. Dr. Andrew Ivy (University of Illinois), Dr. Stevan Durovic, and Marko Durovic were brought to trial for violations of FDA regulations. There is currently no scientific proof that krebiozen is a viable treatment option for high blood pressure, cancer remission or any other condition.

EVIDENCE TABLE

Conditions

Uses
disclaimer: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Grade*

*Key to grades: A: Strong scientific evidence for this use; B: Good scientific evidence for this use; C: Unclear scientific evidence for this use; D: Fair scientific evidence against this use (it may not work); F: Strong scientific evidence against this use (it likely does not work).

TRADITION

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Bilateral pneumonectomy (surgical removal of lung), bladder cancer, cancer (breast, cervical), high blood pressure.

DOSING

disclaimer: The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

Adults (over 18 years old)

There is no proven safe or effective dose for kreboizen in adults.

Children (under 18 years old)

There is no proven safe or effective dose for kreboizen, and use in children is not recommended.

SAFETY

disclaimer: The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to creatine monohydrate.

Side Effects and Warnings

There is insufficient evidence to support the use of krebiozen. Patients should be made aware of the existing treatment options for their specific conditions, particularly treatments with demonstrated efficacy. Pain and mild icterus (jaundice) have been reported. Avoid use in patients with cancer as only negative data has been published.

Pregnancy & Breastfeeding

Kreboizen is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.

INTERACTIONS

disclaimer: Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.

Interactions with Drugs

Insufficient available evidence.

Interactions with Herbs & Dietary Supplements
