Some evidences show that Elderberry can assist in treating the flu. It is known for boosting some immune cells’ production in addition to helping to block the ability to spread a virus. A certain study indicates that taking four tablespoons of a given Elderberry extract, e.g. Sambucol, for three consistent days, the flu’s symptoms, like fiver, can be shortened by 56%. Nevertheless, the study was somehow small and did not have clear implications.


Like other vitamins, garlic is one of the best vitamins to prevent cold and flu. Furthermore, some preliminary evidences show that garlic can reduce risks of catching cold. When consumed when raw or minced, garlic can effectively treat cold. When garlic is overcooked, significant medicinal compounds together with enzymes that make it effective is effective.

A given study proved that Cold fX as a treatment that can reduce the duration as well as severity of signs and symptoms. Though the jury of this disease is out, yet the evidences is somehow promising.


The other name for andrographic is Indian echinacea. It is among the best vitamins to prevent cold and flu while stimulates the immune system. Studies of andrograhics prove that it is one of the best vitamins to prevent cold and flu, especially if it is taken first three days. A good number of studies used Kan Jang, which is a product that combines Siberian ginseng and andrographis.
