Esenvia and Haemovol both contain the active ingredient diosmin, which is believed to improve venous tone and stimulate lymphatic circulation. It is recommended not to take both products at the same time. You could try one product for a month to see if your condition improves. The side effects are generally mild, such as headache, nausea, and stomach pain. Using support stockings with the product is a good idea, but it is unlikely to lower your blood pressure.
