Through coffee retention enemas, we are restoring the alkaline state at the small intestine, thus improving the absorption of enzymes, vitamins and nutrients. This allows liver detoxification as well as enhanced the bowel functioning.

This process will be complemented with liver detoxifiers, raw vegetable juices, antioxidants and a personalized diet. 



Oxidative stress is and outcome of an imbalance between an excess generation of free radicals and decreased endogenous production of antioxidants, this impairs the cell from appropriate functioning, thus affecting the body’s own immune system. The role of antioxidant therapy is essential to counteract these unstable molecules that can impair health and wellbeing. 

Environmental and biological processes that occur constantly in our daily lives result into free radicals. Excess free radicals damage the cell DNA and impairs functionality which can result into disease. The effect of these free radicals can be mitigated through antioxidant therapy. Antioxidants are essential to counteract these unstable free radical molecules that in excess, can result into chronic degenerative disease.


Chelation has been around for many decades. At first, it was only used to treat lead poisoning. Throughout the years and with the contribution of other scientists, it has been documented that chelation therapy can also help eliminate unwanted body’s toxins by improving the circulatory system, lowers cholesterol, and also improves cell function. EDTA and DMSO are essential components which help Chelation therapy. This should be handled exclusively by an experienced qualified physicia


Cancer cells are surrounded by a type of protein shell located at the membrane level, contributing to cancer cell resistance. Proteolytic enzymes destroy the protein shell that surrounds the cell.

In order to provide you with this proteolytic action, these enzymes are to be taken at least one or two hours away from any solid food, mainly animal protein. Proteolytic enzymes are also important immunomodulators, enhancing the body’s own immune system, keeping the cancer cells from spreading.


Amygdalin is a special compound found in apricot kernels that act directly on cancerous cells. Cancer cells contain an enzyme called beta- glucosidase. This enzyme breaks down laetrile into 4 different molecules: 2 glucose, 1 benzaldehyde and 1 hydrocyanic acid (cyanide). This free cyanide is known for its anti-cancer activity, killing cancer cells by intercepting the oxygen uptake at the ferrous portion of the hemoglobin.

 Chelation has been around for decades. In the beginning, it was used to treat lead poisoning. With the help of innovative scientists, we were able to learn that correct treatment with Chelation rids the body of unwanted toxins. Before we go on�a word of caution: Chelation should be delivered exclusively by a qualified, experienced physician. As you will soon learn, many details must be taken into account to deliver an adequate Chelation therapy. At S.M.C., we have over twenty years of experience in Chelation. It is an exciting option because of the vast benefits it offers.
Who should receive chelation?
Please answer this questionnaire:  • Have you received medications for long periods of time?  • Have you been told you have arthritis, diabetes, arteriosclerosis, or high blood pressure?  • Do you suffer from poor circulation or heart problems?  • Are you at risk for a stroke or have a neurological condition?  • Have you received chemotherapy or radiation?  • Do you live in a polluted environment?  • Have you been exposed to toxic elements, such as mercury, lead, or nickel? (To answer this question, check to see if you have amalgam fillings in your mouth)
If you answered ‘yes‘ to any of these questions, or if you know someone who might be interested, please, for your health or the health of a loved one, contact us. 


 Cancer cells are surrounded by a type of protein coating that is destroyed by Proteolytic enzymes. These enzymes keep the cancer from spreading.
Enzymes are more important than vitamins and minerals for general health. Without enzymes, vitamins and minerals are useless. Enzymes are catalysts for metabolic processes and digestion. A catalyst initiates a chemical process without being part of the resultant product.
Proteolytic enzymes or protease can be used, in part, to digest complete proteins that are in meat. Yet, outside of meals, they have been harnessed for a multitude of healing processes, sometimes exclusively and sometimes in conjunction with other therapies. When not used for digestion in the small intestines, these enzymes are free to roam through the blood stream seeking to break down hard protein, fibrin surfaces, scar tissue, granuloma, and even cancer cells' tough coatings.

 Amigdalyn is a special compound that acts directly on cancerous cells. It is extracted from the apricot kernels. The most important part of its molecular composition is hydrocyanic acid, an anti-cancerous compound.  This free cyanide will be poisoning the cancer cell. 


 Vitamin C inhibits tumor growth, helps the production of interferon, and halts the progression of carcinogenic n-nitrous compounds. These nitrose compounds are mostly present in food preservatives, smoked fish, bacon, etc.
They are strongly linked to stomach and colon cancer. During the patient’s booster treatments at Stella Maris Clinic, mega dosages of ascorbic acid is diluted in a solution and administered through a slow intravenous drip. 

Dymethyl Sulfoxide (DMSO)

 Dimethyl Sulfoxide was discovered by Dr. Alexander Zaizeff in Russia, 1866 as a very potent anti inflammatory with analgesic properties. Eventually, Dr. Stanley Jacob and Dr. Herschiller in 1966 discovered the broad therapeutic spectrum of DMSO. Among them is its role as a chelating agent as well as a catalyst of the entry of compounds across the blood brain barrier.

It is also a very potent transporter. It has the ability to carry important biologic natural weapons into the cell without altering the integrity of the cellular membranes with no side-effects.




BRM's are substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts for use in treating cancer, rheumatoid arthritis and other diseases.BMRs used in biological therapies include monoclonal antibodies, interferon, interleukin-2 (IL-2), and several types of colony- stimulating factors (CSF, GM-CSF, G-CSF). Interleukin-2 and interferon are BRMs being tested for the treatment of advanced malignant melanoma. Interferon is a BRM now in use to treat hepatitis C.


 Viscum album is a European type of mistletoe that has been used since the turn of the century in Switzerland and Germany to treat cancer and other diseases.
Scientific information has revealed that this herbal extract helps fight cancer in two basic ways. It works as immunoregulator and has anti-tumoral properties.
It causes the cancer cell to change back into a more differentiated form, thus promoting its regression.
 • - Regulation and/or augmentation of the immune response.  • - Cytotoxic or cytostatic activity directed toward cancer cells.  • - Inhibition of metastasis, differentiation or maturation.  • - Immune regulation and immune restoration.  • - Improved tolerance of normal cells to anticancer therapy.  • - Direct antitumoral effects. 


Autologous vaccine therapy has proven most effective. It is prepared from the patient's own blood which represents his/her unique internal microbial environment. The vaccine is customized to fulfill individual immuno-biological needs. The preparation follows a procedure that favors the development of antigenic peptides and other immunogenic compounds which act in concert to restore the body's natural defense mechanisms.

Clinical research suggests that:  

1. The vaccine stimulates the formation and activation of T-helper cells, macrophages, and natural killer cells.  

2. As an antigen fraction of autologous mycoplasmas and mycoplasma-like organisms, it binds mycoplasma-specific antigens by cluster formation.  

3. It exposes the cancer cells to the immune system by degrading their protective mechanisms. 


These are cells that have been exposed to  an specific antigen and activated. meaning that they have combined with a specific antibody to form a complex capable of reacting with complement components.

 This tells us that human monocyte functions can be altered by products of activated lymphocytes. 

RIGVIR®, innovative melanoma treatment.

 RIGVIR® is the first oncolytic virotherapy medicine that has been approved for cancer treatment and that has been introduced into medical practice, it contains a live non-pathogenic ECHO-7 virus that has not been genetically modified. 

How it works? 

RIGVIR® finds and infects tumour cells. This process is called oncotropism. Subsequently, RIGVIR® replicates in tumour cells and destroys them. This process is called oncolysis. Both processes, oncotropism and oncolysis, are selective for tumour cells and healthy cells are only minimally affected, if at all. Virotherapy is a type of immunotherapy with immune system boosting activity to raise the body’s natural defenses to fight cancer and it is administered as a series of injections according to virotherapy treatment protocols.

RIGVIR® is a prescription medicine approved for the treatment of melanoma, local therapy of the skin and subcutaneous metastases of melanoma and the prevention of relapses of metastases after surgery. In clinical practice RIGVIR® is also used for more than 10 other types of cancer, based on the individual recommendations of physicians.

Side effects 

Cancer virotherapy is a treatment method that is gentle to a body and has minimum side effects. Most common side effect is slightly increased body temperature (up to 37.5°C, 99.5°F) lasting one to three days. 




 Hyperthermia has shown to be effective in almost all cancer modalities. It can also be combined with other cancer therapies.  
It increases the cellular metabolic rate, breaking down glucose to lactic acid and thus decreasing pH to very low levels. High acidity and hypoxemia also damage the vessels that nourish tumor cells, thus choking them off from blood supply. High temperatures kill cancer cells and increases potent effects of herbal and nutritional anti-cancer therapies.
It also damages the membranes, proteins, and enzymes of cancer cells making them more sensitive to other therapies. 

Immunological and biological effects due to heat are accelerated emigration and migration of peripheral blood mononuclear cells, activation of effecter cells, induction and secretion cytokines, and expression of heat shock proteins (HSP) which increases the antigenicity of cancer cells.
During the hyperthermia procedure, the patient is under mild sedation, continuously monitored with O2 saturation, blood pressure, pulse, ecg, and temperature. With the use of thermal probes, the information provided feeds back to the computer that controls the heat exchange unit.
Constant medical and nursing surveillance makes the procedure a safe and reliable therapeutic tool. 

Hyperthermia indications:   

  • For patients with isolated metastasis   
  • Adjuvant treatment in oncology
  • Malignant Lymphomas 
  • Immunological efficiency against tumor cells 
  • Thermal regulation, often disrupted by cancer, can be unblocked.     
  • Hepatitis C.


 Dendritic Cells are bone-marrow-derived professional antigen presenting cells. Dc‘s have the ability to induce primary T-cell-dependent immune responses in vivo and in vitro. This unique feature gives dendritic cells a central role in controlling immunity.
DC‘s are potent antigen presenting cells (APCs) that possess the ability to stimulate naïve T-cells. They comprise a system of leukocytes widely distributed in all tissues, especially in those that provide an environmental interface. 


 It is an effective and powerful treatment for cancer, using insulin to increase the cancer killing effects of chemotherapy. Because of this potentiating effect, lower doses of chemotherapy are used, making it a much safer option than traditional methods in the treatment of cancer.

Patients testimonials

 I am doing well and fully back into my busy life after I left the Stella Maris Clinic in February. I spent a lot of my recovery truly resting and eating well. All of those weeks and months were in an environment of little or no stress, which I am sure, made a big difference.
I am so grateful for everything you did for me at the clinic — not only did the treatment seem to work amazingly well on the cancer, but on my body as a whole.
I hope all is well for everyone there. I’m sending you all my very best wishes and blessings.
JB, Littleton CO, USA     

After our first visit to your clinic M was essentially cancer-free and still further confirmation came from the results of PET scan and chest X-ray. It thus appears that you were more successful than you had supposed. Please extend our kindest wishes to Ofelia, Idania, and of course, your wife Linda.
JM, San Antonio, Texas    

 Happy Holidays,
I wish to thank you and your staff for the fine treatment you afforded me during my stay in Mexico.  I have been feeling better each day, even quit the pain tablets. Hopefully you have me on the right path to complete recovery. Please convey my deepest appreciation, not only to yourself and Linda, but to your staff, especially Ofelia. Feliz Navidad !
