Silver-based drugs have one core common denominator–their active ingredient is their content of "oligodynamic" silver ions (i.e., [Ag.sup.+]). Carl Nageli (1893) first coined the term oligodynamic (from the Greek oligos = few and dynamis = power). Nageli discovered that exceedingly small metal ion concentrations demonstrate extraordinary antimicrobial properties. (1) In 2003, Rentz provided a comprehensive, retrospective review on the universal antimicrobial effects of oligodynamic [Ag.sup.+]. From the historical authoritative medical literature, he documented hundreds of viral, bacterial/spirochete, fungal, and protozoan pathogens that succumb to silver-based drugs containing sufficient amounts of oligodynamic [Ag.sup.+]. (2)

Modern nanoscience is still making new discoveries regarding oligodynamic metals. Nanoscientists appear positioned to develop some of the most complicated strategies for fighting cancer. For example, they are discovering that cancer drugs must be able to easily disrupt and penetrate tumor cell membranes in situ to enable the fullest possible oncolytic effects. Picoscalar or near-picoscalar oligodynamic [Ag.sup.+] hydrosol enjoys the greatest surface presentation (i.e., ~6 [km.sup.2] per gram Ag) (3,4) for tumor cell membrane adherence and penetration, leading to greater oncolytic effects.


The works of Moyasar et al. (1990), (5) Hamilton-Miller and Shah (1993), (6) Zhao and Stevens (1998), (7) Baker et al. (2004), (8) Sondi and Salopek-Sondi (2004), (9) and Morones et al. (2005) (10) collectively established that the therapeusis of bioactive silver extends well beyond its virotoxicity. It is also a broad-spectrum bactericidal and fungicidal agent. Berger showed that oligodynamic [Ag.sup.+] is ten to 100 times superior to silver sulfadiazine for both gram-positive and gram-negative pathogens in terms of achieving the minimal lethal dose (MLD). (11)

It has long been suspected that infectious agents are associated with solid tumor cancers (a notable example is Kaposi's Sarcoma) as well as non-tumor-based cancers such as leukemia. Also, cancer patients often undergo immune suppression therapy, allowing for multiple pathogen foci to seed. Oligodynamic [Ag.sup.+] may have the potential to play a dual role: either destroy the infectious etiological agent of the cancer and/or destroy the pathogen loads arising within immunocompromised patients.


In the US, cancer is the second leading cause of death in humans. (12) Virginia Livingston-Wheeler was among the first to propose an infectious etiology for cancer. (13) Cancer rates stemming from an infectious etiology (e.g., HIV, (14,15) HHV8, (16) HPV16, (17) and EBV (18)), as well as infectious rates from immunocompromised patients (e.g., BK and JC Polyomaviruses, (19,20) Respiratory Syncytial virus, Influenza viruses, and Parainfluenza viruses, (21) Fungemia, (22,23) Rotavirus, (24) CMV, (25) and Streptococcus pneumoniae (26)) have climbed alarmingly over the past two decades. Rentz documented that many of these cancer-associated infections are susceptible to oligodynamic [Ag.sup.+]. (2)


One critical strategic advantage to ~1 nm to 10 nm or less (e.g., picoscalar) silver particles is their ability to absorb, (27,28) interact with, and destroy bacteria; (10) affect abnormal human tissue in situ; (33) or favorably upregulate immune tissues and healing mechanisms. (3) These abilities are augmented by the fact that [Ag.sup.+] hydrosols comprised of the lowest-sized nanoclusters and even picoclusters enjoy the greatest surface presentation and Particle Diffusion Coefficient ([10.sup.-5][cm.sup.2]/sec) for bioactivity ever created. (3,37) At this size range, in vitro studies sponsored by NASA at the University of Wisconsin offer a fascinating mathematical probability: by skillfully administering [Ag.sup.+] hydrosol in vivo to saturate target loci or foci, picoscalar [Ag.sup.+] will impregnate all collective atoms within each tumor cell or pathogen cell with up to one silver ion. (29) This saturation potential supercharges [Ag.sup.+]'s ability to displace the [K.sup.+]-dependent, glucose transport mechanism (the exclusive means by which cancerous cells feed themselves, as opposed to normal cells that enjoy two other additional means to feed themselves), thereby selectively starving cancer cells without harming normal cells.

Landmark studies over the past several decades have demonstrated that oligodynamic [Ag.sup.+] could play a pivotal role in overcoming cancerous processes. This article will review these findings and offer a proposal for future studies and protocol development.

In Vitro Testing

Becker reported in 1985 that his research group had "… studied malignant fibrosarcoma cells (cancerous fibroblasts) and found that electrically injected silver suspended their runaway mitosis." (30,31) In 2003, a similar in vitro test was conducted utilizing 1.44 ppm, 2.88 ppm, 5.75 ppm, 10 ppm, 11 ppm, 11.5 ppm, and ~22.5 ppm concentrations of picoscalar or near-picoscalar oligodynamic [Ag.sup.+] hydrosol against immortal (cancerous) L-929 Murine fibroblast cell lines (ATCC CCL 1, NCTC Clone 929, of strain L, or equivalent source). Respectively, the oncolytic effects upon the cancerous fibroblasts ranged from 55% to 84% and were [Ag.sup.+] concentration-dependent. (32)


In Vivo Testing

Thirty Central American female patients, diagnosed with breast cancer by an oncologist utilizing mammograms and biopsies, comprised a subject group 32 to 52 years of age. Each received a single intravenous dosage of silver-oxide-hydrosol ([Ag.sub.4][O.sub.4]) to achieve a blood plasma concentration of 10 ppm. The 30 subjects were equally divided by three histologic groups: infiltrative canalicular breast carcinoma (Group I), ductile carcinoma, medular breast cancer (Group II), and infiltrative lobular breast cancer (Group III). The dose was administered to 50% of the patients over ten minutes and to the other 50% over four hours within each respective group. (33)


* Group I: At 19 days post-treatment, a re-biopsy of all patients was performed, with a resulting diagnosis of 100% normal mammary tissue.

* Group II: At 23 days post-treatment, re-biopsy of all patients revealed 100% normal mammary tissue.

* Group III: At 29 days post-treatment, re-biopsy showed 100% normal mammary tissue.


Four out of the 30 patients (13%) experienced JHEs (die-off effects) from treatment. These side reactions were minimal, confined to self-resolving, self-limiting, and uneventful hepatomegaly and mild fever. At 30 days post-treatment, silver-oxide-hydrosol appeared to have cured the breast cancers of the 30 test subjects.

Case History: Irving Cohen

In November 2001, 81-year-old Irving Cohen (a) from Adventura, Florida, was diagnosed with primary cancer at the head of his pancreas at Mt. Sinai Hospital by both his gastroenterologist, via ERCP, and his attending oncologist, via follow-up CAT scan. A needle biopsy was performed, but missed the intended mark. Mr. Cohen decided not to repeat the needle biopsy. Notwithstanding, his oncologist informed him he had five months to live.

Mr. Cohen declined conventional cancer treatment and, instead, chose to pursue orthomolecular/nutraceutical support and dietary therapy. He was subsequently treated with a strict macrobiotic-vegetarian diet and supported by per os (p.o.) mega-doses of ascorbic acid, lysine, proline, high-potency green tea catechin extract (EGCG), lipoic acid to recycle and reactivate the ascorbic acid, VascuStatin (Convolvulus arvensis), and Imm-Kine[R] (Muramyl polysaccharide glycan complex).

After four months on his nutritional program, he remained fairly stable. He traveled to Sloan-Kettering, where his original diagnosis was re-confirmed. At that time, the Sloan-Kettering oncologist (who restricted her practice to pancreatic cancer) was asked if the pancreatic tumor could be lymphoma. The oncologist stated clearly that it could not, but added that, without pathology, no one could say with complete certainty.

During Mr. Cohen's trip home, he began to feel weak. He lost his appetite and developed jaundice. A pancreatic bilary stent was installed by his surgeon, but this procedure gave rise to a highly resistant nosocomial infection in and around his pancreatic duct. He was given Cipro[R] and Flagyl[R], but he continued to rapidly decline. We then modified his Complementary and Alternative Medical (CAM) treatment to include picoscalar oligodynamic [Ag.sup.+] hydrosol, both p.o. and administered as a rectal implant. His p.o. dosage was 5 cc every 20 minutes on an empty stomach, and his rectal implant using a bulb syringe consisted of 15 cc to be retained at bedtime.

After five days, Mr. Cohen regained his strength and appetite. However, on day six, he broke out with two 6 [cm.sup.2] herpetic lesions, one anterior and one posterior to his mid-upper right abdominal/flank quadrant, with a single connecting red lesion tracking along the associated intercostal nerve. The patient reported no prior history of shingles. His lesions were subsequently diagnosed as a die-off event from an unsuspected Herpes zoster foci in or near his pancreas. With dermal laser treatment, his painful lesions healed completely after several days. His nosocomial infection also completely resolved.

As his CAM treatment continued, the patient regained greater health than he had previously experienced well before his cancer diagnosis. A second CAT scan confirmed no subsequent growth in the pancreatic cancer. Late into 2002, his primary oncologist reported to Mr. Cohen that he had now concluded Mr. Cohen did not have pancreatic cancer, since he should now be dead!

Sometime thereafter, Mr. Cohen discontinued his CAM treatments. Approximately a year later, he discovered he had developed non-Hodgkin's lymphoma, which was treated with chemotherapy. At the time of this writing, Mr. Cohen, who is now 85, and his wife Audrey are celebrating their 60th wedding anniversary. He remains fairly stable with Retuxin[R] immunotherapy as his sole treatment administered once quarterly.

Investigational Protocol Proposal

Nutritional Loading

Nutritional loading concerns itself with providing an optimal biochemical state to maximize the effectiveness of [Ag.sup.+] while mitigating potential problems. For example, if an unsuspected or underlying hypokalemia is present (i.e., adrenal insufficiency), this should be carefully monitored and treated since [Ag.sup.+] can displace [K.sup.+] to a degree in host cells. Normally, [K.sup.+] is protected from this effect by adequate levels of N-acetyl-cysteine, as recommended below. (34) Fortunately, cancer cells appear to lack antioxidants to defend against this [K.sup.+] displacement by [Ag.sup.+]. (35)

Along related lines of reasoning, ARG antioxidants 30 days pretreatment are recommended to help lessen or eliminate JHEs and a down-regulated liver antioxidant profile. The following doses are for a 75 kilo patient; reduce by body weight accordingly:

* Buffered Vitamin C powder — ten to 20 grams daily according to bowel tolerance

* L-lysine — three times a day (t.i.d.)

* Chemogen[TM] — one t.i.d.

* VascuStatin — two t.i.d.

* Imm-Kine[R] — one t.i.d.

* ThioDox[R] — one t.i.d.

* Phosphatidyl Choline — two t.i.d.

* Aller Aid Formula II — one t.i.d.

* Natural Source E — 800 i.u. daily

* Fibrenase III — three before bed

All supplements are discontinued 72 hours prior to administering the silver hydrosol treatment protocol and are resumed again 72 hours post-treatment for the next 30 days, at which time both the patient as well as the protocol should be completely reevaluated.


Marino (1974) (36) and Berger et al. (1976) (11) confirmed that the effective dosage level of pure oligodynamic [Ag.sup.+] is safe for mammalian tissues. The CRC Handbook to Chemistry and Physics stated that, "While silver itself is not considered to be toxic, most of its salts are poisonous." (37) Picoscalar oligodynamic [Ag.sup.+] hydrosol containing only [Ag.sup.+] and ultra-pure water is virtually devoid of toxicity. The EPA's lowest observed adverse event level (LOAEL) for silver exposure relates purely to argyria, as it is the only established adverse event known for silver exposure. (38,39) For intravenous administration, the EPA has determined that, over any given two-to-nine year period, administering under one gram total elemental silver presents no risk for developing argyria.

Therefore, based on the studies and from a purely mathematical perspective, 100 cc isotonic (b) [Ag.sup.+] hydrosol with a 25 ppm concentration or less could be administered as an IV drip every day for a year without risking the development of argyria. Likewise, a dose of 500 cc (isotonic) of oligodynamic [Ag.sup.+] administered daily for up to 79 consecutive days, or 1000 cc (isotonic) of oligodynamic [Ag.sup.+] administered daily for up to 39 consecutive days, still falls short of the risk threshold for developing argyria.

IV Protocol

Physicians interested, but not experienced, in pursuing CAM IV protocols should first become certified to do so before incorporating them into clinical practice, to mitigate possible liability issues. For further information, the reader is advised to contact the Advanced Medical Education & Services Physician Association at

According to patient tolerance, dosage levels should aim to deliver a 10 ppm [Ag.sup.+] blood plasma concentration over a two-to-four day period. In theory, this would require 633 cc of isotonic picoscalar or near-picoscalar oligodynamic [Ag.sup.+] hydrosol administered via IV drip over four hours daily for four consecutive days, with each [Ag.sup.+] drip followed up exactly 90 minutes later with 125 cc 0.0375% [H.sub.2][O.sub.2] with standard amounts of DMSO, Mg, and Mn, and bicarbonate administered via IV drip over 90 minutes.

For further information, see "A Promising Cure for URTI Pandemics, Including H5N1 and SARS: Has the Final Solution to the Coming Plagues Been Discovered? Parts I & II" (TLDP: #271/272; #273). Part II previously outlined the extension of the oligodynamic therapeusis by way of synergism with [H.sub.2][O.sub.2;] mitigation and management of possible Jarisch-Herxheimer Events; adjunctive CAM supplements for treating influenza; plus the issues surrounding jurisprudence.


More research needs to confirm the oncolytic role of [Ag.sup.+]. Today's nanotechnology has rendered commercially available, high-quality, and cost-effective picoscalar or near-picoscalar oligodynamic [Ag.sup.+] hydrosol. In the near future, the promise of synergistic effects with mildly hypotonic picoscalar oligodynamic Pt, (40) Ag, Au, (41,42) Co, and Cu (33) should prove most fruitful for follow-up investigational cancer research.

Consulting with a compound pharmacist would reveal that by mixing 5.3875 grams of injectible-grade sorbitol into each 100 cc of injectible-grade hypotonic [Ag.sup.+] hydrosol would render the mix isotonic (i.e., ~300mOSM). To avoid any loss of potency of the oligodynamic content within the [Ag.sup.+] hydrosol, the sorbitol should be mixed in to render the [Ag.sup.+] hydrosol isotonic five to ten minutes prior to IV administration.
