ABSTRACT:

The main herbal components and their possible immune-boosting effects are covered in detail in this comprehensive assessment. The review emphasises the definition of immunity, many forms of immunity, The properties and roles of immune-related cells T and B lymphocytes. The immune system is shielded from infection by the anti-inflammatory, antioxidant, and immunomodulatory qualities of these herbs, which also have an impact on immune system signs and symptoms. Additionally, it investigates the effectiveness and safety of herbal immune boosters while taking into account both modern scientific research and traditional wisdom. The increasing popularity of herbal immune boosters—natural treatments made from plants—is covered in this abstract. Cardamom, Ashwagandha, Tulsi, Gingseng, Garlic, Ginger, Amla, and Black Pepper are well-liked natural immunity enhancers.

 

KEYWORDS: Immune System, Herbal Immunity Booster, Antioxidant, Immunomodulatory.

 

 


INTRODUCTION:

The immune system can be defined as a sophisticated association of varied immune cells and molecules that protect against infections and foreign invaders. The innate immune system uses pattern recognition receptors to identify pathogens' molecular patterns, stimulating immune cells like epithelial cells, neutrophils, macrophages, monocytes, and dendritic cells. Prrs also target pathogen-derived pathogen-associated molecular patterns and host-derived damage-associated molecular patterns1. Innate (non-specific) or adaptive (specific) immune systems are the two basic categories used to describe them. Immunoglobulins (Ig), which are created by B cells in response to antigenic assaults from infections and allergens, are associated with particular immunity. The Igs are further split into the classes iga,


igg, and ige, which are all created upon activation via isotype switching. Given that they are prevalent in saliva, tears, perspiration, breast milk, and mucosal secretions, igas are the ones that are most pertinent to the current review.  Additionally, the igas aid in preventing infections and regulating commensal microorganisms at mucosal locations2. The immune system, composed of cells, tissues, and organs, includes white blood cells (leukocytes) that circulate through the body to protect against infectious organisms and invaders3. The medicinal plants and herbs playing a critical role immunity-boosting rasayan kvatha, using medicinal plants and herbs like tulsi, lavang, sunthi, dalchini, kalimiri, and haldi, which have proven pharmacological properties and antimicrobial activity4. Garlic, Margosa Neem, Tulsi, Giloy, Clove, Ginseng, Betel vine, Black paper, Black cumin, Ashwagandha, Licorice, Astragalus, Turmeric, Elderberry and Giloy are plants rich in antioxidants, vitamins, proteins, carbohydrates, dietary fibers, aminoacids, minerals, steroids, alkaloids, and antiviral and antibacterial phytochemicals5.

Innate Immunity:

In-born immunity, also known as natural immunity, is an individual's defense mechanism against pathogenic microbes, encompassing all mechanisms that protect the host from harmful pathogens6. Innate immunity known as nonspecific immunity, now collaborates with the adaptive immune system to safeguard human hosts from infectious insults.  Innate immunity, crucial for host defense against infectious challenges, is also emerging as a key regulator of human inflammatory diseases, including asthma, atopy, and autoimmune disorders like type 1 diabetes, inflammatory bowel disease, and systemic lupus erythematosus7. In the innate immune response, various cells, including phagocytes, dendritic cells, mast cells, basophils, eosinophils, natural killer (NK) cells, and lymphocytes (T cells), play a crucial role. Phagocytes are divided into two main cell types: neutrophils and macrophages. Both share the function of phagocytosing microbes, with neutrophils containing granules that help eliminate pathogenic microbes. Macrophages, on the other hand, are long-lived cells that play phagocytosis and antigen presentation to T cells8.

 

Adaptive Immunity:

The immune system utilizes various receptors, including antibodies, to detect the environment, with the first antigen-specific receptor being immunoglobulin (Ig), a Y-shaped cartoon. The Ig domain, consisting of three globular domains connected by flexible linkers, is a widely used template for various molecules both inside and outside the immune system. Proteins with the Ig domain belong to the immunoglobulin super family, which are soluble molecules that bind to an antigen and signal to immune cells9. Adaptive immune responses rely on custom-tailored receptors created through somatic recombination of gene segments. These evolved through vertebrate gene duplication, generating highly specific and flexible responses. After pathogen encounters, cells expressing these receptors can persist in the host for life10. The adaptive immune system possesses exceptional specificity for antigens through antigen-specific receptors on T and B lymphocyte surfaces, formed through somatic rearrangement of germline gene elements, allowing for the creation of millions of unique antigen receptors11.

 

Herbal introduction:

Medicinal plants, beekeeping products, probiotics and prebiotics, melatonin, and other natural compounds with immunomodulating properties could explore new therapeutic ways to enhance immunity against various diseases. Many vitamins and minerals are also very effective in supporting the proper functioning of immunity12.

 

Herbs used as immunity booster:

Several botanical families, such as Labiatae, Solanaceae, Liliaceae, Zingiberaceae, Argliaceae, Lamiaceae, Euphorbiaceae etc. have several species with established immunomodulating effects. For several decades, for instance, Echinacea, ginger, and fresh citrus juice have all been recognized to have immune-boosting qualities.  Based on the study of plant species from all over the world, an increasing number of herbs with immunostimulating qualities have been investigated and found for use in conventional medicine in recent years. Herbal remedies are thought to be efficient and affordable natural immunomodulators13. Herbal immunity boosters using herbs are mentioned in Table 1.

CONCLUSION:

Herbal immunity boosters are popular due to their natural, holistic approach to boosting body defense systems. However, caution and a critical mindset are essential when using these products. Herbal immunity boosters are believed to strengthen the body's immune system through various processes. Antioxidants, such as vitamins C and E and polyphenols, are found in many natural medicines, helping fight free radicals, lower oxidative stress, and strengthen immune cells. Some herbs also have anti-inflammatory properties, reducing chronic inflammation and supporting a robust immune response. These boosters also promote the growth and function of immune cells, such as natural killer cells, T-cells, and white blood cells, and moderate cytokine responses. Additionally, some herbal medicines enhance immunological memory and promote gut health. According to the plant or molecule, different herbal immune boosters have different levels of success. While some, like Elettaria cardamomum, Ocimum sanctum Linn, Panax gingseng, Withania somnifera, Zingiber officinale, Alium sativum Linn, Foeniculum vulgare Miller, Emblica officinalis have shown promise in clinical studies. Some herbal immunity boosters and above many herbs may help the immune system remember infections which can lead to a faster and more effective response upon re-exposure.
