Immunity is the capability of multicellular organisms to resist harmful microorganisms from entering their cells. Immunity involves both specific and nonspecific components. The nonspecific components act as barriers or eliminators of a wide range of pathogens irrespective of their antigenic make-up. Other components of the immune system adapt themselves to each new disease encountered and can generate pathogen-specific immunity.
An immune system may contain innate and adaptive components. The innate system in mammalians, for example, primarily comprises primitive bone marrow cells that are programmed to recognise foreign substances and to react. The adaptive system is composed of more advanced lymphatic cells that are programmed to recognise self-substances and not to react. The reaction to foreign substances is etymologically described as inflammation, meaning to set on fire. The non-reaction to self-substances is described as immunity – meaning to exempt – or as immunotolerance. These two components of the immune system create a dynamic biological environment where “health” can be seen as a physical state where the self is immunologically spared, and what is foreign is inflammatorily and immunologically eliminated. “Disease” can arise when what is foreign cannot be eliminated or what is self is not spared.
Due to rising viral diseases it has become essential for immunity boost. In events of pandemic like COVID-19 the survival has become essential. Here is a way that can help how boost immune system with herbal nutrition.
