If you've ever Googled for aid with a varicose vein or spider vein, you've probably seen some of the tonics and tablets that promise to "support blood vessel health" and "rapidly reduce venous congestion". Typically, they consist of food extracts (or flavonoids).
What Are the Typical Ingredients for Vein Supplements?
Horse chestnut and grape seed extract are two of the most prevalent flavonoids for varicose vein treatment. Let's look at a few of the assertions. Grape seed extract "helps poor circulation" and "reduces pain and swelling associated with varicose veins". Horse chestnut seed extract "thins the blood", "makes it harder for fluid to leak out of veins", and "promotes fluid loss through the urine (to reduce swelling)".
Pot marigold is claimed to "heal sores" and "help dermatitis." Prickly ash -to "encourage blood flow". Butcher's broom root is said to "cause the blood vessels to narrow or constrict" and "improve blood circulation in the legs by preventing blood from pooling in the veins".
What Does Science Say?
A comprehensive analysis (12 November 2019) of research studies (randomized, double-blind, placebo-controlled trials) on flavonoids to treat varicose veins showed insufficient evidence that dietary extracts are useful in relieving varicose vein symptoms. The study refers to phlebotonics, which includes plant extracts and synthetic chemicals. These are rutosides, hidrosmin, diosmine, calcium dobesilate, chromocarb, Centella asiatica, disodium flavodate, French maritime pine bark extract, grape seed extract, and aminaftone).
Here are some of the review's conclusions:
- Swelling
13 research (including 1245 persons) demonstrate that consuming flavonoids may reduce puffiness modestly when compared to a placebo;
- Quality of life
When it comes to quality of life, moderate-certainty evidence reveals that there is little or no difference between persons who use phlebotonics and those who take a placebo;
- Venous ulcers
Low-certainty evidence suggests that phlebotonics make little or no difference in the healing of ulcers when compared to placebo;
According to researchers, "moderate-certainty evidence from 37 studies (involving 5789 people) suggests that phlebotonics probably produce more side effects, especially gastrointestinal disorders."
The review includes only studies with short-term effectiveness and safety data. As a result, we don't know the medium- and long-term efficacy and safety of using a herbal cure for varicose veins.
We do know that none of these addressed the underlying source of the symptoms, the varicose veins themselves. When patients stopped taking flavonoids, the intensity of their symptoms resurfaced. It is critical to remember the cause of the symptoms you are attempting to address with over-the-counter supplements. Venous eczema, for example, occurs when blood pools in a vein, causing blood pressure to rise and push blood into surface capillaries, causing the skin around it to deteriorate. It feels irritating and itchy, and may appear dry and scaly. The underlying varicose vein ultimately causes this. Until the vein is addressed, venous eczema will persist and possibly worsen.
What Does Help Varicose Veins?
Varicose veins are frequently genetic, but other risk factors include lengthy periods of standing (at work, for example), hormone swings (pregnancy, menopause), age, and others. Once damaged, the veins do not mend on their own. The most recent medical therapies involve treatments that intentionally disrupt the internal vein wall, allowing it to seal and begin to mend before being reabsorbed into the body. To accomplish this, treatments involve a variety of approaches, including injecting a glue or sclerosant and damaging the interior of the vein wall with a laser or radiofrequency energy. Finally, the vein is effectively treated, and blood flow is rerouted to neighboring veins.
Venous illness is frequently a progressive disorder that may necessitate monitoring over time thus additional veins may emerge. However, effective treatment by a phlebologist ensures that you receive the finest care possible and that the disease is managed to prevent painful consequences (ulcers and blood clotting) as you age.
The bottom line
Varicose veins do not heal on their own and require medical intervention. Flavonoids have little (if any) efficacy, increase the risk of gastrointestinal upset, and are simply a band-aid remedy. This is not a permanent solution for a progressive and painful disease.
