Viralgraphis Viral Support

Herbs have been used to support health and well-being throughout history and across cultures and are the cornerstone of many ancient medical systems, including Ayurveda and Traditional Chinese Medicine (TCM). This formula comprises three herbs that have been used traditionally and specifically to support the body’s immune system.

Andrographis Extract: Has been used widely in traditional medical systems as a bitter herb that works quickly to support upper respiratory health and immune response [1]. TCM categorizes andrographis as “bitter” and “cold.” The herb has been used to support temperature regulation, respiratory health, immune function, and cytokine and eicosanoid balance [1-4]. A randomized, double-blind, placebo-controlled study investigated the use of 1200 mg/day (standardized to 4% andrographolides) in 158 adult patients. Results revealed that individuals receiving the herb had a significant improvement in several of the parameters measured when compared to placebo. A “high degree of effectiveness” was observed by day two of treatment [5]. Research on andrographolide, a major constituent of andrographis, suggests that this bioactive component supports immune activity in human cells by increasing proliferation of lymphocytes, production of interleukin-2, tumor necrosis factor-alpha and cluster of differentiation (CD) marker expression [6,7].

Licorice Root Extract: Medicinal use of licorice dates back to ancient Greece, China, India, and Egypt. Contemporary research suggests that its active component glycyrrhizin, supports the human immune system in the presence of pathogens [8,9]. A 2004 study found that glycyrrhizin more effectively supported immune function than other compounds studied (ribavirin, 6-azauridine, pyrazofurin and mycophenolic acid) [10]. Research suggests that mechanisms of action for glycyrrhizin include induction of T-cell interferon-gamma and interference with the pathogen’s membrane [9]. Long-term intake of high doses of glycyrrhizin may deplete potassium and exacerbate hypertension [11,12].

Indigowoad 10:1 Root Extract: Is commonly used in TCM to support the immune system and upper respiratory tract. A closer look at the mechanism of action for indigowoad root extract in animals revealed that the extract significantly increased spleen weight as well as the number of circulating white blood cells, lymphocytes in particular. The same study found that the indigowoad extract stimulated macrophage phagocytic activity and reduced the suppressive effect that hydrocortisone has on the immune system [13].
