#3 – Spinach
This leafy vegetable is rich in iron and chlorophyll, which are not only good for purifying blood, but could also be effective in preventing unnecessary loss of blood through nosebleeds and the like. Raw spinach is considered a laxative and a diuretic, and its high sodium content can also make it effective against herpes. Cooking spinach considerably reduces its vitamin and mineral content. Use it in salads and other similar foods to get the most benefits.
