Chronic constipation and a circulatory system weakness cause hemorrhoids and varicose veins. 

There are external hemorrhoids and internal hemorrhoids. External are easily identifiable and usually more painful. Internal hemorrhoids are varicose veins and can be present for years without any problems. Bleeding can be the first sign of internal hemorrhoids. Constant bleeding over a period of time can cause anemia. Liver congestion has been implicated as a cause of hemorrhoids. But they also occur as a result of pregnancy, a junk-food/ low-fiber diet, lack of exercise, sitting while working, heavy lifting, and obesity. Constipation adds excess pressure to these veins, interrupting the blood flow toward the heart.
Witch hazel compresses can speed circulation and help in healing.  Butcher’s Broom acts as a vasoconstrictor and contains anti-inflammatory properties. Yarrow opens the pores of the skin permitting a greater discharge of internal poisons through perspiration. Agrimony is high in nutrients necessary for healthy functioning of the colon, intestines, kidneys, liver and stomach. Poppy seeds can be used as a poultice for relief from swelling. Poppy seeds are loaded with dietary fiber, a type of carbohydrate found in plant-based foods. Fiber not only adds bulk to your food and stool -- which helps keep you feeling full and prevents constipation -- but it also lowers blood cholesterol levels. Oatstraw helps reduce high blood pressure by reducing cholesterol levels, thus increasing circulation, its benefits directed to the brain and body.
