Echinacea and immune system
Echinacea has broad effects on the immune system by affecting different types of white blood cells and immune system components. It enhances macrophage function, which helps filter the blood and signals other immune cells to mount an attack. It also stimulates T cells and B cells, increasing immune responses. Echinacea boosts natural killer cells, which help fight cancer and viruses. Additionally, echinacea activates the complement system, which is one of the body's first lines of defense, and has been shown to have antiviral properties against influenza, herpes, and cold viruses. Through these diverse effects on the immune system, Echinacea provides robust support for immune health.

Biologia humana 12
The immune system consists of lymphatic organs, antibodies, and regulatory agents that work together to defend the body against diseases. The primary lymphatic organs are the red bone marrow and thymus gland, where lymphocytes originate and mature. Lymphocytes then congregate in secondary lymphatic organs like the spleen, lymph nodes, and tonsils. When tissue rejection occurs, the immune system recognizes and destroys cells bearing foreign MHC antigens. Diseases of the immune system include autoimmune disorders, where the immune system mistakenly attacks the body's own cells, and immune deficiencies, where the immune system is unable to adequately protect against disease.

How Does Metabolism Work?
Dr. Carolyn Dean is a medical doctor and naturopath who has authored over 35 books. She explains that metabolism is the physiological process that breaks down food and converts it into energy to power the body's functions. A person's weight is determined by a combination of their calorie intake through food and drink and their physical activity level. The metabolic system mixes calories with oxygen to create energy. Even at rest, the body requires energy to perform essential processes like blood circulation, breathing, and cell repair and growth. A person's basal metabolic rate, the number of calories burned at rest, depends on factors like muscle mass, sex, age, and body composition. Additional factors that affect daily calorie burning are physical activity levels and
Introduction to Neurogenesis
Until relatively recently, most neuroscientists believed that humans are born with all the neurons they are ever going to have. During childhood, we may produce new neurons to help build ‘neural circuits’, the pathways that serve as information highways connecting different locations of the brain. However, it was believed that once this neural circuit was established, adding new neurons would simply disrupt the flow of information throughout the brain, essentially disabling its communication system.

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

Pharmacology of 5-hydroxytryptamine and Antagonist
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.

- 2. 2 The Role of Skin in the Human Immune System Skin is an important immune organ that serves as a protective interface, shielding organs and tissue from the environment. Skin provides a physical barrier from the pathogenic organisms, toxins, and physical stresses encountered in everyday life. Dr. Carolyn Dean Skin protects the body from infection, toxins, and cancer. Sometimes referred to as ‘skin-associated lymphoid tissue’, the skin immune system includes the lymph nodes, as well as peripheral lymphoid organs such as the spleen. Key immune cells in the ep- idermis are skin cells known as ‘keratinocytes’, and epi-

In addition to lymph and blood vessels, the dermis contains numerous immune cells, including mast cells, dermal dendric cells, B cells, T cells and natural killer cells. Immune cells are continuously traf- ficked between the blood circulation, the skin and draining lymph nodes. The skin microbiome is an important contributor to homeostasis of the skin immune system. In terms of protecting the body from infection, the skin is the first line of defense. Langerhans cells in particu- lar are thought to play a pivotal role in detecting and transporting antigens to lymph nodes and other immune cells to initiate an immune response.
