CDS is a concentrated 0.3% (3000ppm) aqueous solution of chlorine dioxide and has a neutral pH.
According to in vitro and in vivo studies, chlorine dioxide in the form of CDS is broken down to salt (in minimal amounts) and oxygen in the body. Therefore, CDS is able to increase oxygen levels in the blood, whether used orally or intravenously. At the same time, it eliminates pathogens due to its recognized *biocidal capacity and rapidly reduces metabolic acidity, which is the true cause of most diseases known today.
*Biocidal describes substances, mixtures, or microorganisms that destroy, deter, or control harmful organisms (bacteria, viruses, pests) through chemical or biological means.
CDS, according to more than 5000 physicians of the international COMUSAV organization is the greatest discovery in medicine in the last hundred years. Chlorine dioxide is a chemical commonly used in water treatment.
It is used to destroy pathogens found in water. The FDA, WHO and other agencies worldwide have approved its use in drinking water because of its safety and efficacy. It is widely used around the world to remove bacteria, viruses and other pathogens through oxidation, leaving no harmful residues.
It is important to differentiate between thegas and the aqueous solution, since as a gas it can be dangerous because in air it is reactive and can cause irritation, in water it is non-reactive.

CDS is not chlorine (Cl2), bleach, hypochlorite (NaClO) or sodium chlorite (NaClO2), nor does it contain them. Nor is it MMS, CD or a mixture of 2 components; it is just pure chlorine dioxide gas dissolved in water. In fact, chlorine dioxide technically does not contain a single molecule of chlorine ! It is finally converted after intermediate reactions into a chloride ion and oxygen. Sodium chloride is common salt and oxygen and both are essential for our body.
Chlorine dioxide has different forms of being produced and the outcome is not the same. CDS does not contain any sodium chlorite salt and therefore does not produce any harmful by-products when used dissolved in water. The main advantage of chlorine dioxide in the form of CDS is its neutral pH and its safety for human and animal health.
Chlorine dioxide does not produce toxic / carcinogenic trihalomethanes (THMs).
CDS eliminates bacteria, viruses, fungi, *prions and also virus spike by oxidation, just as it happens in our body with *macrophages and not by intoxication like antibiotics. Simply put, pathogens are incinerated.
*Prions – A prion is an infectious, misfolded protein that causes normal cellular proteins to adopt the same abnormal, infectious shape.
* Macrophages are large, specialized white blood cells of the innate immune system that engulf and destroy pathogens, cellular debris, and foreign substances through phagocytosis
Is CDS toxic?
According to toxicology, all substances can be toxic, depending on the amount, duration and concentration. The U.S. Environmental Protection Agency (EPA) establishes a toxicity of 292 mg/kg, that is similar to the toxicity of caffeine. This means that a 70 kg person should consume 20,440 mg of a gas dissolved in water for 14 days. At a concentration of 30 mg in 1 liter of water, which is the standard daily dose, 681.33 liters per day should be consumed. Even if it is mistakenly consumed in a concentrated form at 3000 ppm, it will still be 6.8 liters. CDS, in high concentrations, causes throat irritation and this makes it difficult to swallow. Therefore severe intoxication, by oral intake is technically impossible.
In 2021, the distinguished Mexican businessman Pedro Luis Martin Bringas (Soriana Group) has submitted a formal offer of $2 million dollars before a notary, addressed to any individual who can demonstrate, in a substantiated manner, that CDS is toxic in the doses used. He has also officially contacted the U.S. Food and Drug Administration (FDA), however, to date, he has not received any response.
Although large amounts of gas should not never be inhaled, it is safe to take CDS orally, intravenously, buccally (into the mucous membranes of the mouth), transdermally (through the skin) or applied directly to the skin, according to peer-reviewed scientific studies. It is effective in treating any bacterial or viral infection. Therefore, it is safe to use in appropriate doses.
Does CDS work for viral infections?
A peer-reviewed macro study ( Aparicio Et.al) evaluated the effects of Chlorine Dioxide (ClO2) as an alternative therapy for the treatment of COVID-19. Data from 1,136 patients treated with three different ClO2 protocols at an average dose of 1.41 mg/kg were analyzed. The average recovery time was 4.84 days and the total duration of treatment was 15.87 days. Only 6.78% of patients experienced temporary mild reactions such as headache, dizziness, vomiting, diarrhea and transient nausea that could be related to the underlying Covid. There were no dangerous side effects to the patients’ health. Blood tests showed no abnormalities after ClO2 consumption. Liver enzymes, glucose, total cholesterol and triglycerides returned to normal at the end of treatment. 99.03% of patients recovered without complications. These results demonstrate that ClO2 is effective and safe for the treatment of COVID-19 when used at the appropriate concentration and dose.

Types of CDS:
There are two technical methods for producing chlorine dioxide: CDS and CDE. The first method uses a mixture of components, wherein the precursor, sodium chlorite [NaClO2], is mixed with an acid (hydrochloric acid [HCl] or citric acid) by capturing only the gas in a glass jar with water or by bubbling the gas through water via pumping.
The second method is CDE (electrolytic chlorine dioxide), which produces chlorine dioxide through electrolysis and preferably microfiltration.

A Protocol Example –
PROTOCOL A
Protocol A has proven useful for beginners or those who have doubts about how to start with the use of CDS (chlorine dioxide solution) and wish to start with a low dose and increase gradually. The instructions for Protocol A are detailed below:
Day 1: Take 2 ml of CDS and mix with 200 ml of water before going to sleep.
Day 2: Take 3 ml of CDS in a liter of water throughout the day. Divide these intakes into several times during the day.
Days 3 onwards: The daily dose is increased by 1 ml, reaching 5 ml of CDS in one liter of water per day. You can increase 1 ml per day until this amount is reached.
Important: If you experience any discomfort or side effects, such as nausea or stomach upset, you should reduce the concentration to the previous dose that you tolerated without problems.
This protocol can be used long-term and also serves as a maintenance and prophylaxis approach.
If after 7 days you are comfortable with 5 ml of CDS, you may choose to increase the dose by following Protocol C.

Interactions
Over the last 16 years, no interactions with other medications taken an hour apart have been observed, which is logical since medications generally do not react with abundant substances like oxygen and salt in the body.
Venous blood gas measurements have indicated a 30% increase in blood oxygen when taken orally. This increase lasts about 2 hours.
Additionally, a reduction in acids (LAC) and an improvement in renal hepatic values (CREA) have been noted, unlike with conventional drugs. Significantly, CDS cannot cause chemical burns due to its neutral pH. However, at high concentrations, it can oxidize natural tissue colors, similar to liquid oxygen.
There are no reported contra-indications for pregnant or lactating women in scientific literature or during the 16 years of usage. To date, many positive reports on its biocompatibility have been published.
Contraindications:
Do not inhale massively! Inhalation should be avoided for safety reasons (except by experienced physicians and in hospitals). However, CDS concentrate can be applied to the skin as a spray. Do not use occlusive dressings with the concentrate to avoid irritation.
Known Interactions:
CDS reacts with antioxidants such as synthetic vitamin C and loses its efficacy. Therefore, simultaneous use of antioxidant pharmaceutical supplements should be avoided. No issues have been described with the ingestion of vegetables or other foods if taken half an hour apart.
Adverse Effects:
No serious adverse effects have been reported after many years of use or in three peer-reviewed clinical trials involving more than 3500 patients [Aparicio et.al, Insignares et.al, and others] and thousands of independent medical clinical reports. No adverse signs were observed in hepatic, renal, and QT levels either. They even subsequently improved.
Side Effects:
According to current studies, only 6% of patients have experienced mild effects. These are considered transient healing crises (Herxheimer) and are very low. The effect is higher in people taking many medications (polymedicated, intoxicated by heavy metals and/or parasites) and is usually due to toxin accumulation.
Mainly observed effects include increased urination, tiredness, dry mouth at high doses, mild headache, slight increase in mucous activity, reflux, and temporary increase of gases. All these symptoms disappear after 7 days or upon discontinuation of use.
Storage:
CDS concentrate is preferably stored in brown glass pharmaceutical bottles in the refrigerator. The cap should always be tightly closed to prevent the gas from escaping as it is very volatile. Temperature has not shown to be a relevant factor in tightly closed bottles during transport. CDS is affected by ultraviolet light; therefore, it is advisable to store it away from the sun and preferably in dark or protected places. The yellow color is a good reference for concentration and as long as it remains yellow (sunflower oil color or greenish yellow), it is effective. If over time the color loses intensity, just increase the amount appropriately for use. There is no scientific evidence that CDS affects PET plastic at daily diluted concentrations. Like other medicines and special substances, it should be stored out of the reach of children.

This book is optimal for people who doubt the veracity and efficacy of CDS, backed by more than 30 doctors with data that is useful both for the “Long Covid” and for counteracting the harmful effects of “mRNA vaccines” by helping to restore health to those who suffer.
This Book provides the clinical evidence that CDS works and is not harmful.
