Hirudin is a naturally occurring peptide in the salivary glands of medicinal leeches (Hirudo medicinalis) that has a blood anticoagulant property. This is fundamental for the leeches’ alimentary habit of hematophagy, since it keeps the blood flowing after the initial phlebotomy performed by the worm on the host’s skin.A key event in the final stages of blood coagulation is the convertion of fibrinogen into fibrin by the serine protease enzyme thrombin.[4] Thrombin is produced from prothrombin, by the action of an enzyme, prothrombinase, in the final states of coagulation. Fibrin is then cross linked by factor XIII to form a blood clot. The principal inhibitor of thrombin in normal blood circulation is antithrombin III.[3] Similar to antithrombin III, the anticoagulatant activity of hirudin is based on its ability to inhibit the pro-coagulant activity of thrombin.Hirudin is the most potent natural inhibitor of thrombin. Unlike antithrombin III hirudin binds to and inhibits only the activity of thrombin forms with a specific activity against fibrinogen.[3] Therefore, hirudin prevents or dissolves the formation of clots and thrombi (i.e. it has a thrombolytic activity), and has therapeutic value in blood coagulation disorders, in the treatment of skin hematomas and of superficial varicose veins, either as an injectable or a topical application cream. In some aspects, hirudin has advantages over more commonly used anticoagulants and thrombolytics, such as heparin, as it does not interfere with the biological activity of other serum proteins and can also act on complexed thrombin.

Product Name :Siberian Ginseng Extract
Latin Name: Eleutherococcus senticosus
The Siberian ginseng bush grows between 3-10 feet high, with a main stem and long branches covered by thorns. Yellow or violet flowers grow in clusters on the plant, which turn into round, black berries. Siberian ginseng is native to the Taiga region of the Far East (southeastern part of Russia, northern China, Korea, and Japan) and renowned worldwide for helping to promote good health, endurance and vitality. It has been a staple of Oriental medicine for 5,000 years and is respected for its invigorating value.
Siberian Ginseng contains remarkable compounds, Eleutherosides, which stimulates mental and physical vigor. Numerous scientific publications on Siberian Ginseng have demonstrated anti-fatigue effects, improved stamina and performance, increased alertness and learning ability. Most of these have been confirmed in human trials. Siberian Ginseng has been a popular self-medication among people who are undergoing convalescence, under excessive stress or strain, overworked, weakened by chronic illness, and those who need to achieve peak physical and mental performance. There are also a considerable number of reports indicating its support for the immune system, restoration of abnormally low blood pressure, improvement in the circulation system, normalization of disturbances in sugar and fat metabolism, anabolic effects in the liver, testes, bone marrow and other vital organs.
1. Prevent Stress-related Illnesses.
Siberian ginseng contains eleutherosides that favorably affect the adrenal glands, the small glands that rest atop the kidneys and secrete stress-fighting hormones. Taking the herb is believed to boost the body's capacity to handle physical stresses ranging from heat exposure to extreme exertion. Resistance to disease increases as well. So does one's overall energy level.
2. Combat Fatigue and Restore Energy.
Eleutherosides has been shown to enhance mental acuity and physical endurance without the letdown that comes with caffeinated products.5 Research has shown that eleutherosides improves the use of oxygen by the exercising muscle.6 This means that a person is able to maintain aerobic exercise longer and recover from workouts more quickly. Preliminary research from Russia indicates it may be effective for this purpose.7
3. Stimulate Body’s Immunity
Siberian ginseng extract was shown to stimulate cellular immunity. It was found to stimulate T-cell production, especially helper cells. Thus Siberian ginseng is touted for numerous immune-related disorders. German scientists have found that this herb may be useful for treatment in the early stages of AIDS. It is found to retard the spread of the virus by a synergistic action of the elevated numbers of both helper and cytotoxic T cells.
Dried, powdered root and rhizomes of 2- 3 grams per day can be used14. Concentrated solid extract standardized on eleutherosides B and E, 300-400 mg per day, can also be used, as can alcohol-based extracts, 8-10 ml in two to three divided dosages. Historically, eleutherosides is taken continuously for six to eight weeks, followed by a one- to two-week break before resuming.
