Vitamin C is probably the most well known natural cure for the common cold and flu. Vitamin C increases macrophage activity (one of the cells of immune system), and has an anti-histamine effect which helps reduce the runny nose. Under stress most animals (except humans) make significant amounts of vitamin C from glucose. Therefore vitamin C is considered the stress vitamin.
Echinacea is the most well known herbal cure for the common cold. It supports the immune system and increases the production and activity of white blood cells, lymphocytes and macrophages (cells of the immune system). Echinacea can be taken both to prevent a cold and to treat one. Many companies make echinacea glycerites, which are suitable for children.
Garlic is another cure for the common cold that has anti-bacterial, anti-viral and anti-fungal properties. Louis Pasteur confirmed its anti-bacterial action in 1858. Many people eat a raw clove of garlic a day to help support their cardiovascular system. Due to its heavy odor, many people prefer taking garlic capsules. The active part of garlic is allicin, which unfortunately is destroyed by cooking.
