[Used for] 2 Stars Influenza 3 to 5 ml of liquid formulas or 300 mg of powdered root supplements three times per day [Why] 
Taking echinacea may help clear flu symptoms faster. Echinacea has long been used for colds and flu. Double-blind trials in Germany have shown that infections associated with flu-like symptoms clear more rapidly when people take echinacea.19 Echinacea appears to work by stimulating the immune system . The usual recommended amount of echinacea is 3-5 ml of the expressed juice of the herb or tincture of the herb or root, or 300 mg of dried root powder three times per day. Wild indigo contains polysaccharides and proteins that have been reported in test tube studies to stimulate the immune system. The immune-enhancing effect of wild indigo is consistent with its use in traditional herbal medicine to fight the flu.20 However, wild indigo is generally used in combination with other herbs such as echinacea, goldenseal , or thuja.
