Echinacea root (Echinacea angustifolia)
Traditional Indications
Echinacea angustifolia is the premium variety and stronger than Echinacea purpurea and the root is premium in comparison to the aeriel parts. Echinacea is anti-microbial, anticatarrhal, alterative and immunomodulator. Echinacea is one of the primary remedies for helping the body rid itself of microbial infections. In combination with Yarrow or Bearberry it will treat cystitis. It is especially useful for infections of the upper respiratory tract such as laryngitis, tonsillitis and for catarrhal conditions of the nose and sinus. In general it may be used widely. (1)
In Traditional Chinese Medicine Echinacea is known as Zi Zhu Hua 紫锥花. Zi Zhu Hua enters the Lungs & Spleen channels to activate Wei Qi (immune system Qi), releases the exterior, scatters Wind-Heat & clears toxins. It is indicated to treat bother upper and lower respiratory tract and indeed any infection. (2)
Pharmacognosy
Echinacea has anti-viral properties through its action to increase interferon (IFN). (3-5) & is comparable with the antiviral drug Oseltamivir. (6)
IFNs are proteins known as cytokines, molecules responsible for triggering Immune defences to help eradicate pathogens. IFN are named for their ability to "interfere" with viral replication by protecting cells from virus infections. IFNs also activate immune cells, such as natural killer cells and macrophages; they increase host defences by up-regulating antigen presentation by virtue of increasing the expression of major histocompatibility complex (MHC) antigens to help immune cells differentiate self cells from foreign invading cells. Flu like symptoms" including fever and muscle pain are caused by the production of IFNs and other cytokines. (7)
Immune-modulatory activities comprise stimulation of phagocytic activity of macrophages & suppression of proinflammatory cytokines & chemokines responses of epithelial cells to viruses & bacteria. (8)
Echinacea angustifolia displays antioxidant effects and lowers inflammatory mediators IL-1β and TNF-α in colitis and may likely have some therapeutic favourable effects in the management of ulcerative colitis UC. (9, 10)
