I have found that many products are effective against varicose vains, but many don't have any effect against varicose vains. It is hard to figure out what the effectiveness of a product really is, because so many different kinds of varicose vains may be involved. In my practice I will generally suggest that you start with one or two products that have shown significant effect, and use this as a basis for more thorough research.
If you are interested in a more comprehensive study of varicose vains, I recommend the following review paper, " Varicose Vains in Humans " from the Journal of the American Medical Association. What are Varicose Vains? Varicose vains are tiny veins that run along the sides of the intestine, or the inside of the small intestine ( jejunum ) and sometimes in the vagina. There are two types of varicose veins: varicose subacute (small) and varicose pericardial (large). Varicose subacute varicose veins have a diameter of less than 2 mm and can be very painful. Varicose pericardial varicose veins are usually not painful at all, but are very painful when they begin to enlarge. Varicose subacute varicose veins can be seen on a regular basis and they can be painful, even if you don't have any signs of them.
