Factors predisposing to B6 deficiency are low dietary intake, excessive protein intake, alcohol and oral contraceptive use. During infection, one of the body's defense mechanisms to limit bacterial growth, is to reduce plasma Iron. There is much scientific evidence to support the conclusion that iron supplementation is not indicated during acute infection, especially in young children. However, in patients with impaired immune function, chronic infections and low iron levels, adequate supplementation is essential. Many herbs have significant antibiotic action against bacteria, viruses and fungi.
Many herbs show remarkable effects in stimulating our own immune mechanisms.
Modern research is upholding what herbal practitioners have known for thousands of years, that herbs work with our body's systems to affect health. Perhaps the three herbs most widely used by Naturopaths for enhancing immune functions are Echinacea, Goldenseal and Licorice. Recently, this herb has been shown to have significant immuno-enhancing activity. Its major component, insulin, is an activator of the alternative compliment pathway. This pathway is responsible for increasing non-specific host defense mechanisms, like neutralization of viruses, destruction of bacteria and increasing the migration of white blood cells to areas of infection.
