Law of Similarity

The law of similarity has been observed since ancient times, but the first to study and clearly enunciate it was Hippocrates. He explained in his writing that there are two completely opposite ways to face diseases: the way of opposites and that of the similar, destroying the curative use of the toxic. Any substance that in its experiment on healthy subjects has caused the appearance of a given complex symptoms will be able to influence positively a similar set of symptoms, whatever its origin, producing an increase in defense mechanisms.

Hippocrates observed that medicine approaches treatment one of two ways, depending on objective observation of the signs of illness: that of the contrary, or “contraria contrariis curentur” and, that of the similar, “similia similibus curentur”. Both are used as a motto of the ruling forces of nature, “Vis medicatrix naturae”.
Hippocrates was the first to abandon mythological and pre-scientific concepts, introducing systematic observation and methodology to medicine, favoring the inductive method which parsed the particular to the general, from effects to causes, and from concrete facts to theoretical principles, challenging all the speculative theories.

In his text, “Places in Man” he introduces this approach, differentiating from that of opposites and affirming the need to individualize treatment, devising a plan of therapy in response to those observations: “We would cure sometimes with the contraries, according to the nature and the origin of the disease. Sometimes with the similarity, again according to the nature and origin of the disease.” And also affirm, “Most parts of diseases are curable with the same cause that they have procured,” and, “The disease is produced from the similarity and through the similarities they produce, it can bring the sick back to health from the sickness.” So strangury treatment, which did not exist before, came into existence now, as the cough like strangulate, is caused by the same things.

However, in his book there are also traces of the pre-Hippocratic theories. Regardless, it’s evident in his writing that he had a remarkable capacity for observation of all natural phenomena.

Such premises make us clearly understand why, for example, in the treatment of freezing, we can use two opposite therapeutic techniques: the identical approach of rubbing the frozen body part with ice, or the opposite by applying heat. Similarly, in treatment of overheating, we can apply heat or cold. Both techniques are effective (all people who live in snow know and apply these techniques, and know that a hot drink or shower is a very effective means to treat overheating). But there is a fundamental difference between the two methods: the use of the contrary sees the body take such action passively, and the use of similarity creates an active reaction that persists well beyond the moment of the actual stimulus, and leads to significantly faster healing.

Obviously this reactivity of the body doesn’t happen only in thermal type stimulations; the reactive model is useful with all substances presented in nature, that is, every substance is capable of causing both toxic and perturbing effects, and both reactive and curative effects. But, while in the cold and heat example, we used the identical principle, in Homeopathy we use the substance that can induce in the body of healthy subjects symptoms most similar to those appearing in the diseases that we want to cure.

For what reason? The logic of the law of similarity is strict and clear: If the symptoms, as experience shows, are a sign of positive reaction in the body, the administration of substances that produce similar reactive symptoms will determine a strong acceleration towards healing.

The law of similarity is often used empirically, perhaps even unconsciously. For example, we can quote some healing practices used by the “curandero,” real wizards of the indigenous Mexicans. They were, in fact, using various types of herbs, in many cases exploiting the capacity of “anti,” but in others with the criteria of similarity.

Curiously, the source for these cases is the magazine Veterinary Science, no. 6 of November-December, 1987.

Reading the statement of the curators is almost laughable when it comes to showing obvious concerns about contradictions of certain cited phenomenon. Let’s read verbatim: “It’s not all clear. There are apparently contradictions between the known specific activities of some plants and the use made of it by the natives. For example “the Agave cupreata” is used as an antidote to snake poison, while from the performed study, it should contrarily increase the rate of absorption and enhance its activity to some poisons. The “Crotone dragon” that contains different irritant substances, is used instead with success as anti-diarrhea and anti-keratotic. The “Rose cabbage” is given a mild laxative action. On the contrary, containing certain proportion of tannin, it would be more logical to assume that it can be equipped with an astringent action (petals are used in infusion). The “Sida Acuta” traditionally used as anti-diarrhea contains alkaloid that should cause diarrhea.

It’s obvious that the writers of the article don’t understand Homeopathy. They cannot express more concern about the facts mentioned, while they are nothing more than a perfect application of the principle of similarity.

However, for such empirical applications, two fundamental principles are missing – those of dilution and succession. And we can’t talk about homeopathy without simply considering its effects as being due to herbal medicine.

By doing so, however, might there be a risk to seriously worsen the disturbed patient? Going back to the freezing example, if we continue to rub with ice for an indefinite time, we will get the opposite result of what we want, thereby delivering the subject to the so-called “white death”. Stimulations by way of similarity have to be minimal and measured, and for that reason, homeopathic substances are used in infinitesimal doses. Hahnemann used the technique of progressive dilution to avoid worsening of patients.
This technique has remained unchanged since then.

It is important to consider the law of similarity in determining a course of treatment, with awareness of both advantages and disadvantages of the various approaches, and to design treatments in such a way that best serves the patient.

The Homeopathy Aggravation

Homeopathy Aggravation: the reaction

In this chapter we will primarily analyze the reaction of aggravation. Understanding the aggravation phenomenon is facilitated from the series of considerations that follow, and concerns the way the body reacts when faced with a morbid stimulus.

Administration of a homeopathic remedy chosen according to the law of similarity may cause any of the following reactions in the body:

– an improved picture

– a worsening picture

– appearance of new symptoms

– re-appearance of old symptoms

– no response

In the chapter dedicated to health, disease and healing, we saw how taking the correct approach to a disease is fundamental to success in medical treatment, and that this can be derived exclusively from an understanding of the body’s defense mechanism. Recognizing that symptoms presenting during the evolution of a disease progression is not actually an expression of the disease, but on the contrary, the best possible response of the body to it, is an indispensable key to this understanding.

In fact, if we consider symptoms as not an expression of the disease but of the body’s reaction to the disease, it becomes easy to understand the action mechanism in the law of similarity. As stated in the chapter dedicated to that law, that concept is that a substance in its pathogenesis causes a body reaction, and a determined procession of symptoms will be able to positively influence a similar symptomatic picture, whatever its origin, as it will produce an increase in defense mechanisms in its place.

The highlight of this reality becomes easy to explain even with the apparent strangeness of the fact that a homeopathic substance can influence a morbid picture supported by a virus, bacteria or toxic and poisonous substance, without possessing any kind of direct or specific action against them. In fact, the body sophisticated product of a long evolution in the environment of numerous interaction systems among its various components it uses to maintain the real state of homeostatic, there are fundamentally two systems: the internal, or alarm system, and the external, or defense system.

External alarms are built from that wealth of sensory information, genetically printed or acquired through experience, and teach their own parents, allowing us to recognize and face any possible danger as well. Internal alarms are principally represented by painful stimulus, vigilant and irreplaceable sentinel that watch over the basic alert functions, and play the role of limiting or even completely preventing normal motor activity until the disease is gone. The defense system is instead built from all these structures; from the immune system to the nervous system, they intervene against any type of external aggression. These two systems demonstrate their action through multiple channels, but in the end, symptoms combine with each other in many different ways depending on the morbid stimulus and the real individual reactivity.

To simplify comprehension of such mechanisms, imagine a nation protected by their armed forces, and equate the various armed corps and their headquarters as the body defenses, regulated by the central nervous system. Facing an enemy attack will be naturally defended by a frontal defense (represented by the skin, mucous and the excretory systems). They put in place those measures (that is, the symptoms) permitting the total elimination of the enemy as far as possible and his expulsion with the destroyed structures in the battle. Such symptomatic measures are represented by different draining symptoms (vomit, diarrhea, transpiration, drooling and others).

Among other important parameters are the adenoids and tonsils, a real bulwark against an enemy attempt to invade the territory using major communication roads and sliding (circulatory and lymphatic systems). At this point, we reflect on what can be the actual result of surgical removal of the cited structures; it would be as if central command is facing an attack that is causing death and destruction in one of the most important border posts, and instead of sending reinforcements and munitions, he decided to make such stronghold for not having further lost in site.

It is obvious that the immediate result of such a move would be the death of those regional problems, but with the logical consequence of finding the final, after short time to fight the enemy in the heart of the country, altogether with the risks. In addition to “blitzkrieg” lightning war, that can bring total defeat of the invasion or the invader. There is, of course, another possibility – that of the country being invaded by massive forces but not dominant over those defenses, therefore creating a trench war, with nuclei invaders nested in different strategic points of the territory, where continuously or periodically violent attacks or simple disturbance actions are thrown. This is chronic disease, with its periodic aggravations and expression of a stalled situation between the body and the disease, with symptoms representing more than ever the vital processes of maintenance of such a precarious balance.

Going back to the example of tonsils, when the invader is able to take over of such structure and to settle (possible chronic tonsil rather than possible serious damages to primary structure like the heart, kidneys or joints), there is objective situation of our defense structure, neuralgic at the bay because of the flow channels which has become all the effects of enemy territory. So, while being clear that the primary purpose will always be regaining our position, keeping an eye on other invasions in the future can sometimes be necessary. In the trench wars that destroy even vital bulwark in order to avoid continuous infiltration of enemy elements in all the territory, with the consequences that can arise.

Even in total victory (with resolution of the problem at all levels with tonsillectomy), it’s reasonable to expect possible, if not probable, serious trouble in case of future invasions in any provenance; these invaders will soon have the way smoothed from the definitely irreparable absence of this defense line and they have to be faced in the main street of the main city. Fortunately, our body possesses exceptional defense mechanisms, and even this type of situation normally allows for effective dealing with any type of invader. In light of this reality, it is certainly comforting to realize that they were not trained to treat our body, but to do everything to impede outstanding defense mechanisms.

Hence, the big opportunity that homeopathy offers to us is that it gives powerful help to the body, according to natural laws. In summary of how many display we propose this mathematical model: facing an aggressor, the body put in action the army perimeters 1, 8, 17, 37, 99,” and evaluated the most suitable ones (for example vomit, nasal discharge, perspiration, diarrhea and fever). If we want to provide help to the body, we have to give it a remedy independent from the causes, it stimulated in its pathogens, the same response channel. In more serious cases with deeper levels of invasion, both perimeters and internal defense armies are put into action (1, 10, 18, 37, 79) vomiting, hepatitis, jaundice, diarrhea and flatulence, homeopathic remedy will always be useful to have these prominent symptoms in its pathogens.

The body defenses to any act of invasion won’t be so different from the different possible combinations of intervention of different defense departments that will have visible manifestations that we call symptoms. Even including the absurd conceptual of “anti” therapy, such therapies are justified in cases where there are no alternatives equally ready and available, and there is a serious life and death situation because of a highly altered homeostasis of the subject. In this case, the antibiotic remains a fundamental therapy, and is irreplaceable because the damages that may result from its use are clearly insignificant compared to the risk of death of the subject; insignificant, but not to be underestimated. In fact, as recent studies showed, beyond the primary and secondary toxic effects coming from molecular activity, there is a process of the connective tissue of catabolites and waste from different origins, caused by the inhibitory drug action, that actually prevents their expulsion through the excretory organs.

The action of the molecule “anti” is ultimately like “bills of exchange,” of the “promissory” that is best used just when it’s with the water in the throat, without more energy stocks. However, it’s possible to remove such accumulation of harmful worms even at different times, when the body has had time to recharge its own batteries, but finding the right remedy certainly is never easy or simple.
Until now, our discussion has only sought to clarify the mechanism of body reaction and how it can then justify the aggravation phenomenon.

Long Hair Cat

Do you have long haired cat? Are you demoralized by inextricable knotting?

You know that there is a solution, and incidentally it’s the food.

No one has ever discovered the cause that makes this annoying but dangerous cluster of hair, I can assure you that I saw many cats stop having this problem by eliminating from their diet all the foods that contain meat derived from intensive farming, obviously first of all the various brand kibbles.

What makes these knots form? Simply an inflammation of the sebaceous gland, which puts abundant sebum secretions, that ends up becoming a great glue.
It can only be eliminated through careful use of scissors.
If you cut the knots and change to food to one that uses fish from the sea as its protein, you will see that in most cases, the problem will not reappear, indeed, the hair will be shiny and smoother than you have ever seen, with no need for daily brushing.

If you like it, let me know how it worked for you!

Food Intolerance: An Inflammatory Process?

An intolerance can cause an inflammatory phenomenon and / or increased secretions and excretions.

It’s not difficult to notice that the two mechanisms cited are really those that the body has to defend from substances recognized as toxic: expelling, with secretions and excretions, or “burning them” with an inflammatory process.

Such a phenomenon can hit any organ, because each individual has a different sensibility. We will see, then, dogs and cats with (almost always chronic) ear infections, conjunctivitis, dermatitis, gastroenteritis, cystitis, nephritis, arthritis and so on.

A food that the body is intolerant to will cause an acute inflammatory process whenever such food is ingested.

If the food is part of the daily diet, the inflammatory process will become inevitably chronic.

The use of an anti-inflammatory medication should be exclusively chosen for the cases where it’s not possible to remove the cause of the inflammation, if the inflammation phenomenon causes a state of life too debilitating, or if the disease is based on autoimmune and when the cause is unknown and unidentified.

Taking a step in the animal world, I can easily say that most of the inflammatory processes that currently affects our dogs at home are caused by food intolerances.
By eliminating the “harmful” food, it will be possible to avoid the use of specific medicine because the inflammatory process  will quickly regress spontaneously.

How to Recognize Intolerances and Allergies

Given the growing spread of diet-related diseases, it is important to refine as much as possible the difference between allergies and food intolerance.
Following are the basic concepts distinguishing one from the other, and highlighting the distinctive elements of the two diseases.

Summary table of the distinctive signs of each disorder:

  • Allergy: Involvement of the immune system;
  • Intolerance: Physical-chemical reaction without involvement of the immune system;
  • Allergy: Rates of response to diet by deprivation for between 20 and 90 days;
  • Intolerance: Rates of response to diet by deprivation for between 2 and 20 days;
  • Allergy: Localization of lesions and itching nose, lips, armpits, belly, limbs;
  • Intolerance: Localization of lesions and itching of the outer ear, neck, underarms, back, thighs, scrotum, wrists;
  • Allergy: Almost exclusively bilateral;
  • Intolerance: Lesions tend to be unilateral;
  • Allergy: Reaction rate in less than a few hours;
  • Intolerance: Between one and ten years;
  • Allergy: Mainly skin and gastrointestinal problems;
  • Intolerance: Involvement of all primary systems, with inflammation and / or increased secretions and excretions;
  • Allergy: Not affected by the amount of allergen;
  • Intolerance: Reaction influenced by the allergen dose.

An Imbalance Between Omega3 and Omega6

Did you know that an imbalance of Omega3 and Omega6 can cause a tendency to obesity?

In agricultural production, commercially raised livestock is fed corn silage and given oxytetracycline to reduce the incidence of infection. This antibiotic is stored in the animals, and leaves a toxic residue in their systems so this and the resulting higher Omega6 levels from the silage make it into our milk and food, leading to an Omega6/3 imbalance in our bodies.

In infants, an obesity epidemic (we refer to epidemic when there are a high number of cases of a specific pathology, regardless of whether it is actually infectious) can only logically be linked to these higher Omega6 levels in milk, since it comes primarily from silage-fed milk cows.
Grass, on the other hand, is very rich is beneficial Omega3, especially in the spring, allowing pregnant females to have a large quantity of it in their blood, so their fetuses benefit as well. Because of this natural diet, grass-fed livestock do not impart oxytetracycline residues and higher Omega6 levels to our food. I remember that Omega3 is also essential for brain development, and nothing is left to chance.

Going back to obesity, the situation in the US is an obvious example, where obesity has become a national emergency. However, it is necessary to emphasize that if we observe the population of a large North American city – an ideal place to see millions of people in one place – it seems that people are largely either of normal weight, or are extremely fat. There is little in between. My belief is that certain individuals become obese because their system is unbalanced due to a diet overly rich in Omega6 and poor in Omega3, linked to the agricultural production methods described above. It’s true that some individuals just eat too much, but I believe that is more due to this imbalance.

In support of this point of view, the American Journal of Lipid Research recently published an article which blamed the imbalance ratio between Omega6/3 in food for the development of obesity. According to this study, presented by Professor Gerard Ilhaud (University of Nice-Sophia Antipolis in with CNRS, INRA), the imbalance of Omega6 and Omega3 promotes obesity from one generation to another. This is extremely important because it could explain why children of obese people often have the same fate.

As proof, the researcher exposed four generations of mice to an occidental type diet, replicating the imbalance between Omega6/3 (10/1) and noticed that the weight of the mice gradually increased in subsequent generations. To explain this transition from one generation to the other, it’s necessary to involve the epigenetics: which is to say that the genetic heritage (genoma) can’t be modified, but that we can alter the operation of some genes by adjusting food.

Let’s remember that Omega6 and Omega3 are essential polyunsaturated fatty acids that do not naturally occur in the human body, and must be acquired from food. In the past few decades, obesity has significantly increased as the fat characteristics of our food have changed.
Thus, it’s not difficult to connect this increase in obesity with the increase of Omega6 in our diet to the detriment of Omega3. The ratio of Omega6/3 has tripled or quadrupled in forty years, with the United States
ratio at 40/1, while in Europe, the average is 10/1 – which is already too high.

I would like to point out that this idea isn’t crazy or irresponsible. In fact, it has been shown that the minor addition of Omega3 right flax seeds in the diet of breeding cattle has shown to be very effective in improving both the health condition of the animal and the quality of the products they provide (milk, meat, cheese and yogurt).

The breeding of animals for food is an unsustainable practice for many reasons. There are ethical considerations, but there is also a need to stop the intensive farming which has a high price in generating waste and pollution from animal excrement in the form of methanol gas, and the negative effects of the chemical and pharmacological products used in the production cycle.

As I said, Omega3 is present in flax seed, canola, hemp and fish, especially fatty ones (salmon, sardines and mackerel are especially rich). So it is recommended that humans eat this type of fish once or twice every week. I also saw that it helps in keeping the skin hydrated.
Fish consumption should be limited; since the average life span is now around 90 years, there can really be an accumulation of heavy metal toxins. This is not an area of concern for cats and dogs since their life span is five times below that of humans. Paradoxically, there are more stringent controls on raw materials intended for dog and cat foods, than for human foods.

I believe there is ample evidence indicating that imbalance in the Omega6/3 ratio can affect both our bodies and our eating habits. With minor adjustments in agricultural processes for livestock, along with increased consumption of high quality Omega3 foods, people can reduce their tendency to obesity.

Dogs of All Breeds, are Having Increasing Difficulty Giving Natural Birth

Increasing Difficulty Giving Natural Birth: a focus on all breeds dogs

Considering that the females of every species has always given birth without the intervention of a surgeon (obviously risking life and, often, losing it), it seems logical to try to understand why. It’s understood that the C-section represents a very important instrument for saving those not able to give birth. As a male, it’s easy to be accused of having no justification to weigh in on this sensitive issue. I have no intention of being judgmental, I just want to communicate my nearly thirty years of veterinary experience.

The difficulty on the part of the female has increased progressively since the 1970’s, and currently the rate of Cesarean sections is high. The question arises: is this necessary or forced? Behind the caesarean section, for both doctors and veterinarians, is a tempting business. Clinics can easily take advantage of the legitimate fear of childbirth. Mothers are often terrified by stories from relatives, friends, and acquaintances. I have to admit that for many years, I was convinced that women had become unable to bear the slightest pain. Instead, I now realize that many women can’t give birth even if they put forth their best will and have not been influenced by others.

It seems too simple to be real, and yet, veterinarians have observed that the cause is the acute nutritional shortage of Omega3. I have already abundantly reported on the reasons behind this shortage (If you would like to deepen your understanding, continue reading my articles at, so I will limit myself to stating Omega3’s ability to elasticize cell membranes. This plays a role in all of the structures that carry out a successful childbirth: the dilation of the cervix, relaxation of the pelvis, contraction of the uterus, and the coagulation of torn veins and arteries.

A nutrition rich in fish, fish oil, olive oil, and flax seed should enable a natural birth without great difficulty and suffering of the mother. I am just a simple veterinarian, but why not apply this knowledge to women? If there is a doctor reading this, I would be happy to compare information regarding this sensitive issue.
I invite all women who are thinking of giving a natural birth (I have read from statistics that those who appreciate my work the most are those between 25 to 35 years old, the age at which we most often think of having children) to prepare at least six months before the birth by incorporating the suggested foods into their diet.

Of course, I invite all of those who are either parents or dog breeders, and have decided to experience the miracle of pregnancy, to use nutrition rich in Omega3.

A Vegan Diet for Diabetics?

Did You Know that a Vegan Diet is Very Effective for Diabetics?

Dr. Alberto Donzelli, the ASL in Milano, Italy, suggests a vegan diet for those with diabetes.

This strategy was born from a scientific study that divided 100 patients (“assisted person” according to a new definition, which I consider absolutely ridiculous) affected by diabetes in two groups of 50. The first group followed the guidelines of the American Diabetes Association (ADA) with a diet consisting of 15-20% of calories from protein, less than 7% from saturated fat, and 60-70% from carbohydrates and monounsaturated fat, for a total of 500-1000 calories daily.

The second group followed an integrated vegan diet with Vitamin B12, comprised of 65% or more calories from carbohydrates with a low glycemic index, 20% fat and 15% protein. This diet “was based on vegetables, fresh fruit and dry oil, integral cereals and vegetables, with a bit of oil added.
Everyone was allowed to drink alcohol – one drink per day for women and two for men.”

From every perspective, the vegan diet was the winner. The superiority of the vegan model, in fact, was realized in 67% of those following a vegan diet versus 44% of the patients who followed the ADA diet, with weight loss achieved at six pounds versus four pounds. Moreover, the vegan diet allowed for a sharp reduction of anti-diabetic medicine (43% vegan versus 26% ADA), a major reduction of LDL cholesterol (23% versus 11%), and glycated hemoglobin (1.48% versus 0.81%).

Though “vegan dog” may seem a contradiction in terms since they are obviously forced to eat as their owners dictate, many seemed to feel good on this diet, so why not try it before a disease becomes serious?
In the vegetarian diet, it’s necessary to pay close attention to the mixture of plant proteins to ensure inclusion of all necessary amino acids, so as not to risk a nutritional deficit.

The Forza10 vegan diet is perfectly balanced, and can be a great way to check the effects of diet on these increasingly widespread illnesses in both humans and animals.
We also offer Forza10 Weight Control, specifically formulated for those with Type 2 Diabetes.

And, on our website,, you can also find , Forza10 Immuno.
This has been shown to turn an autoimmune disease like Leishmaniasis into a “normal” form, with a return to clinical health. For those who are interested, we can provide the poster presented at the World Congress of Recife in Brazil, where we were among the top eight chosen from three thousand exhibitors, and the subject of a panel discussion of medical and veterinary specialists around the world.

You may want to try a vegan diet if you have diabetes, as research indicates it can have a significant impact on the manifestations of the disease in the body.

Is Inflammation a Body Healing Process?

Conventional medicine tends to automatically seek to suppress symptoms during sickness, when inflammation is an indication of the body “repairing” itself.

When you take an anti-inflammatory drug, that natural defense response in the body is smothered, which seems to cause a continuation and increase in chronic and/or degenerative diseases.

In practice, inhibiting this natural response of the body to defend itself from illness or negative stimulus, we prevent and force the elimination of the defense system, causing the body to rebalance with an increase in chronic or degenerative diseases.

Consider this metaphor: City trash is eliminated by burning in an incinerator. While it removes the trash from the city, the burning itself creates new issues in generating smoke, heat, noise and toxic emissions. But if we “switch that off” by turning off the incinerator, have we really done the best thing? In that case, we leave the trash in the city and pollute the environment. Likewise, by switching off inflammation in the body with medicine, we still leave harmful toxins in the body.

If the stimulus of the disease persists, the body is forced into a state of chronic inflammation. It’s debilitating and painful, but effective (if the waste continues to be produced, the incinerator will obviously be forced to work continuously).

Anti-inflammatory drugs may be the only choice in some cases where it’s not possible to remove the cause of the inflammation, or when this is either unknown and/or unidentified.

Food intolerances, the field in which SANYpet is the undisputed leader, can cause their own inflammatory issues and/or increase in secretions and excretions. Such phenomena can affect any organ, as each individual has a different sensibility.
Where food intolerance exists, there can be acute inflammation every time that food is ingested. And, if that food is part of the daily diet, the inflammation will inevitably become chronic. If we fail to remove the cause, we cannot eliminate the effect.

In sum, it is important to determine what is causing inflammation in the body before initiating anti-inflammatory treatment.
Sometimes it’s best to let the body defenses operate naturally, so as not to create even more issues or further development of chronic or degenerative conditions.

Are Vomiting and Diarrhea Essential Defense Mechanisms?

Vomiting and Diarrhea: precious essential defense mechanism

When the body comes into contact with a toxic substance or poison through the gastrointestinal system, it does the most logical thing it can do: get away as fast as it can from the toxic substance through vomiting and diarrhea.

Vomiting is an extremely direct way; whatever is in the stomach that the body perceives as toxic is directly rejected. The body is so sophisticated that vomiting can be initiated even from the duodenum, the first section of the intestines.

In fact, it is able to reverse the direction of peristalsis motion (the movements that “push” the contents toward the natural exit), bringing it to the stomach and then expelling it.

When the poison gets further into the intestines, the body does another entirely logical and functional thing: it increases the speed of peristalsis in order to expel as soon as possible.

Thereby, the intestinal contents will fortunately only be partly absorbed, becoming semi-liquid or liquid at the rectum and generating diarrhea.

In these ways, the body prevents absorption of toxins or poisons ingested via the stomach.
It would seem from this that vomiting and diarrhea are indeed essential defense mechanisms.
