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.

Immune system cells are normally present as cells circulating in blood and lymph, as collections anatomically defined 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 mononuclear phagocytic system represents the second largest cell population of the immune system and consists of cells that have a common lineage whose main function is phagocytosis. After maturation and subsequent activation, they may present several morphologies. The undifferentiated cell type that enters the peripheral blood after leaving the marrow is called a monocyte. Once fixed in tissues they mature and become macrophages.

There are several types of immune response. More broadly, the different types of immune responses fall into two categories: innate responses (natural immunity) and specific or adaptive immune responses (acquired immunity). Natural immunity is that present at birth. It is the defense mechanism we have before we even expose ourselves to any foreign substance. This is the main line of defense against invading organisms and the first response to a microbial attack. Their mechanisms are fast, fixed in their mode of action and effective in disrupting most infections at an early stage, however, they do not always have the ability to eliminate the infection. Its characteristics are those that it presents throughout life, having neither specificity nor memory. The components of innate immunity are mechanical barriers, secreted products, and include mononuclear phagocytes and Natural Killer cells. The innate immune response not only exerts an important protective function but also serves to initiate and regulate the subsequent acquired immune response. The acquired immunity is not present at birth but is acquired as part of development. The acquired immunity can be divided into two broad classes: (1) antibody-mediated or humoral immune response, where the specific recognition of the antigen in the effector phase is mediated by the antibodies. And (2) cell-mediated immune response, which is directed against cells carrying foreign antigens on their surface. The cell-mediated response is physiologically more important for eradicating intracellularly living microbes or viruses.
