Indications:

1. Anti-inflammatory action: apparent suppression of inflammation due to planted wool when the product is injected into abdominal cavity of rat [8]. Sodium rutin sulfate has very strong anti-inflammatory action to edema of rat [9].

2. Actions like Vitamin P: maintain the strength of blood vessel, reduce its permeability and brittleness; degreasing action to liver fatty infiltration, especially together with glutathione.

3. Antiviral action: best suppression to phlyctenular stomatitis virus at product concentration of 200g/ml [10, 11].

4. Inhibition of aldehyde reductase: 95% inhibition at a concentration of 10-5M [12], which facilitates the treatment of diabetic cataract.

5. Toxicity: mice, intravenous injection, LD50 at 950mg/kg.

6. Clinical use: for the prevention of intracerebral hemorrhage, hypertension, retinal hemorrhage, purpura and acute hemorrhagic nephrosonephritis; for treatment of chronic tracheitis with effective rate at 84.8% and 98%. Its derivative, troxerutin, or Venoruton, is applied clinically for burn, arthritis, and all kinds of blood vessel diseases. Commodity drug is available in abroad [14], while the drug has been successfully developed in domestic. With Effective rate for the treatment of cerebrovascular diseases is 87.8%; 88% for retinal edema and hemorrhage [3].
