Homeopathy Science

About Us

Dorly de Freitas Buchi, a renowned Brazilian researcher, holds a Ph.D. in Biological Sciences (Biophysics) from the Federal University of Rio de Janeiro. Her solid academic background is reflected in the publication of several scientific articles in the field of Cell Biology. Professor, for more than 40 years at the Federal University of Paraná, she combines extensive experience in higher education, both in undergraduate and graduate courses, and effective contributions in the sphere of the university administration. Her orientation activities are remarkable, from scientific initiation to doctorate, having promoted the training of a large number of young scientists.

Despite this exemplary academic trajectory, what makes Dorly a special human being are her unique qualities: loyalty, courage, tenderness, and tenacity. Woman, mother, sister, and friend, she is endowed with profound sensitivity, a conciliatory spirit, and the ability to aggregate people and ideals around a greater good. Her respect for life, in all its forms, has always guided her in search of health promotion and a better life for all. And so, in her continuous overcoming of challenges, guided by an acute scientific curiosity and her non-conformity with the paradigms and limitations of traditional medicine, in an untiring spirit and an unwavering purpose of serving collective interests, firmly carried out research based on highly diluted drugs and complex biological response modifiers. A significant part of the results of her efforts and her holistic view is presented in this book which, as an author, proposes to contribute to life, health, and the construction of happiness for all.

About Homeopathy

Immune System and Homeopathy Studies using macrophages treated with different homeopathic medicines have resulted in a significant increase in the activated/resident macrophage ratio compared to control groups (water, hydroalcoholic solution, and untreated). Different macrophage receptors were altered, both in expression and distribution, in addition to altering the production and release of different cytokines and reactive oxygen and nitrogen species…

Homeopathy Science

  • Like cures like: This principle states that a substance that can cause symptoms in a healthy person can cure those same symptoms in a sick person. For example, if a person gets a rash from contact with poison ivy, then a homeopathic remedy made from poison ivy might be used to treat a rash with similar symptoms.

  • The law of minimums: This principle states that the smaller the dose of a remedy, the greater its effect. Homeopathic remedies are often diluted to very high levels, but practitioners believe that this dilution makes them more effective.

  • The single remedy: This principle states that only one remedy should be given at a time, so that its effects can be clearly observed.

  • The totality of symptoms: This principle states that the remedy should be chosen based on the whole picture of the patient’s symptoms, not just the physical symptoms. This includes the patient’s emotional and mental state, as well as their lifestyle and preferences.

The existence and unexpected pathways in my life.

In this book, I tell the story of my life and my relationship with science, and especially how this journey resulted in 20 years of basic research in homeopathy.

Throughout their evolutionary history, multicellular animals have been infected by microorganisms. In response, they developed a series of defenses that are used today. Physical and chemical barriers, such as the skin and mucous surfaces, confine microorganisms to the external surfaces of the body and, when pathogens manage to break through these barriers, they are sought and destroyed by the immune system.

Its objective is to recognize foreign invading agents, with the potential to cause disease (known as a pathogen), prevent their spread, and finally, eliminate them from the body. Thanks to this system, animals have the ability to resist almost all types of microorganisms or toxins that tend to damage tissues and organs and still, often, protect us from infections and cancer cells.

 And some pathogens are responsible for the great knowledge acquired by scientists. Knowledge is generally acquired little by little, but the advent of HIV has produced a leap in that knowledge. And now with SARSCOV-2, it seems that again scientists are at an impasse, and for that reason, they are going deeper and deeper into research and learning more about the immune system.

Why are they at an impasse?

Why the opinions and the results of the research differ from what was established until then?

People who have certainly had COVID-19, where antibodies are not detected; people who where the presence of antibodies has been detected and who are no longer found; people who defend themselves well, with few symptoms; people who apparently have natural resistance; in short, there is no standard response behavior to this virus.

And as new researches and new discoveries are happening, leave your immune system activated using M8 daily.

This system is composed of numerous types of cells and a variety of molecules which are spread throughout our body. Immune system cells are normally present as cells circulating in the blood and lymph, as anatomically defined collections in lymphoid organs and as cells dispersed in virtually all tissues. Like all blood cells, the cells of the immune system also originate in the bone marrow, where many also mature.

The hematopoietic stem cells of the medulla originate precursor cells or basically 3 groups of specialized progenitor cells: lymphoid progenitor and myeloid progenitor, which will give rise to leukocytes or white blood cells, and the erythroid progenitor, which will give rise to erythrocytes or red blood cells. The lymphoid progenitor divides and differentiates to give rise to lymphocytes (B cells, T cells, and NK cells).

The myeloid progenitor divides and differentiates to produce at least six cell types: granulocytes (neutrophil, eosinophil, and basophil); the mast cell, the dendritic cell, and the circulating monocyte, which originates the macrophages residing in the tissues. The erythroid parent gives rise to erythrocytes and megakaryocytes.

Lymphocytes are the coordinating cells of the immune system. However, all lymphocyte functions depend on non-lymphoid cells, the accessory cells, which are not specific for different antigens. Accessory cells are mononuclear phagocytes, dendritic cells and several other cell populations, such as granulocytes and mast cells.

Lymphocytes – Lymphocytes are the only immunocompetent cells capable of specific antigen recognition and any macromolecule, viral particle or cell that contains a recognized structure and linked by an immunoglobulin or T cell receptor. When a student looks at a blood smear histological slide, the lymphocytes all look the same, as they are morphologically homogeneous, but they consist of distinct subsets, that perform different functions and that can be distinguished phenotypically. Lymphocytes called B are the cells that produce antibodies (glycoproteins that bind to antigens). Some lymphocytes called T-cells that express surface CD4 function as auxiliary cells to stimulate the production of antibodies and to activate macrophages to destroy phagocyte microorganisms. CD4 T lymphocytes can still be divided into Th1 and Th2 depending on the secreted molecules. Other T lymphocytes express CD 8 and function as cytotoxic cells to destroy target cells that are expressing foreign antigens. Other lymphocytes called NK lyse virus-infected cells and certain tumor cells.

They mature in the thymus, which is why they are called T lymphocytes. In this organ, T lymphocytes acquire specific CD4 or CD8 membrane receptors, in addition to a TCR (T cell receptor), most of which have αβ chains (95%) and a few gamma-delta chain (γδ). They are activated by cells presenting antigens and cytokines. Its main function is to act on specific or acquired immunity. They differ according to their function in: cytotoxic (CD8), auxiliary (CD4), natural killer (NKT), memory (CD45), regulatory (FOXP3) or gamma-delta (γδ).

Within these groups, there are still several subgroups. Regulatory T cells (Treg) are a subpopulation of T cells with distinct development and function, which express the forkhead box transcription factor P3 (FOXP3) and are indispensable for maintaining immune tolerance to self and homeostasis. Dysfunctions in these cells can lead to serious problems such as fatal autoimmune diseases, immunopathologies, and allergies.

These lymphocytes, when activated by cells such as macrophages, become able to perform their functions. And who activates the accessory cells to make this link? M8
