Other common name(s): original version was known as Hansi; Enercel Plus, Enercel Forte, or Enercel Max

Scientific/medical name(s): none


Enercel is an herbal preparation consisting of very small dilutions from plants of the desert and rain forests such as cactus (Cacti grandiflora), aloe, arnica, lachesis, and licopodium in a 2% to 8% alcohol base.


Available scientific evidence does not support claims that Enercel, Enercel Plus, Enercel Forte, or Enercel Max is effective in treating cancer or any other disease.

How is it promoted for use?

Proponents claim that Enercel enhances the immune system, prevents and stops the progression of some types of cancer, increases tolerance of side effects from chemotherapy and radiation therapy, and effectively treats chronic fatigue syndrome, AIDS, and asthma.

The proprietors of Enercel claim that the remedy helps asthma, stroke, Bell’s palsy, and numerous other disorders. They claim that more than 150,000 people with cancer have reported positive responses with Enercel treatment. Currently, the company is licensed in El Salvador.

What does it involve?

Enercel is taken by mouth in drop form, by nasal mist, through a nebulizer, or delivered by injection. The basic formula includes about 10 components, the proportions of which are adjusted according to the condition being treated and whether the drug will be delivered orally or by injection. The U.S. Food and Drug Administration (FDA) has not approved Enercel injections.

What is the history behind it?

Hansi, the original formula, was claimed to have been developed by an Argentine biologist Juan Jose Hirschmann, PhD, who introduced his homeopathic formula in Buenos Aires in 1990.

What is the evidence?

Available scientific evidence does not support claims that Enercel or Enercel Plus is effective in treating cancer or any other disease. No studies testing this treatment could be found in the National Library of Medicine’s PubMed database of medical journal articles. One Web site that promoted Enercel-Hansi around 2005 included a page with the heading “Studies.” Although the page included experimental methods, results, and conclusions that were formatted to resemble a medical or scientific journal article, the authors provided no information regarding whether the manuscripts were ever published in any peer-reviewed journal. Because publication in such journals is considered standard practice among medical researchers, therapeutic claims that are promoted directly to the public and not subjected to the scrutiny of scientific experts cannot be considered reliable evidence.

As of early 2013, the “Studies” section of the Enercel Web site contained no completed studies of people with cancer. Although it lists some planned human cancer studies, none of them mention using scientific methods such as control groups, randomization, or blinding.

Are there any possible problems or complications?

This product as sold as a homeopathic remedy in the United States. If sold without a prescription, a homeopathic remedy must be intended for self-limiting illnesses (such as a cold or muscle strain) rather than serious illness. These products are regulated as a special category of over-the-counter (OTC) drugs. A big difference between standard OTC drugs (such as aspirin or antibiotic ointments) and OTC homeopathic remedies is that detailed documents showing scientific proof of safety and effectiveness must be provided to the US Food and Drug Administration (FDA) before conventional standard OTC drugs are sold, but OTC homeopathic remedies aren't required to do this.

Not enough is known about Enercel to determine whether it is safe for humans. Like most homeopathic remedies, it is a dilute liquid that has very little if any of its original components in each dose (see our document Homeopathy). Relying on this type of treatment alone, and avoiding conventional medical care, may have serious health consequences.
