The present invention demonstrates through many experiments that Rosmarinic acid (RA) can inhibit the expression of connective tissue growth factor (CTGF) and therefore is useful for the prevention or treatment of hepatofibrosis and nephrofibrosis. Based on this, the present invention provides novel uses of RA and pharmaceutical compositions comprising the same in the manufacture of medicaments useful for the prevention or treatment of chronic hepatitis, CRF, and diabetic nephropathy.

1. Use of Rosmarinic acid as a connective tissue growth factor inhibitor. 2. Use of Rosmarinic acid in the manufacture of medicaments useful for the prevention or treatment of diseases related to abnormal expression of connective tissue growth factor. 3. The use according to claim 2, wherein said diseases related to abnormal expression of connective tissue growth factor include but are not limited to hepatofibrosis and nephrofibrosis. 4. The use according to claim 2, which is the use of Rosmarinic acid in the manufacture of medicaments useful for the manufacture or treatment of chronic hepatitis. 5. The use according to claim 2, which is the use of Rosmarinic acid in the manufacture of medicaments useful for the prevention or treatment of diabetic nephropathy. 6. The use according to claim 2, which is the use of Rosmarinic acid in the manufacture of medicaments useful for the prevention or treatment of chronic renal failure. 7. A pharmaceutical composition, comprising of an effective amount of Rosmarinic acid in the prevention or treatment of diseases related to abnormal expression of connective tissue growth factor, and pharmaceutically acceptable carriers or excipients. 8. The pharmaceutical composition according to claim 7, wherein said effective amount of Rosmarinic acid are in the range of 25-1,500 mg, preferably 25-750 mg when injected; 50 mg-3,000 mg, preferably 50-1,500 mg when taken orally. 9. The pharmaceutical composition according to claim 7, which is in the form of tablets, capsules, pills, solutions for injection, freeze-dried powers, or emulsions for injection, preferably tablets, pills, or freeze-dried powders. 10. The pharmaceutical composition according to claim 9, which is prepared by the following steps: 2,000 volume unit of water for injection use is added to 50.0 weigh unit of Rosmarinic acid to dissolve it; add NaOH until pH=5.5˜7.5; add 8 weigh unit of mannitol, and stir until it completely dissolves; pyrogen-free clear solution is obtained after ultrafiltration and 2 ml of the solution is filled into each 10 ml tube vials; lyophilisation process is carried out to obtain lyophilised preparations with 50.0 mg of Rosmarinic acid in each vial. 11. The pharmaceutical composition according to claim 9, which is prepared by the following steps: 100.0 weigh unit of Rosmarinic acid, 35.0 weigh unit of sucrose, 40.0 weigh unit of lactose, and 23.0 weigh unit of Sodium Carboxymethyl Starch are mixed well and passed through 100-mesh sieve; 3% of PVPK30 solution is added as needed to make a damp mass, which is then granulated through 20-mesh sieve; after dried at 60° C. for 3 hours, the granules are passed through 18-mesh sieve; 2.weight unit of magnesium stearate is added and mixed completely before compressed with shallow concavity to obtain tablets weighing about 200 mg and containing 100 mg of Rosmarinic acid each. 12. The pharmaceutical composition according to claim 8, which is in the form of tablets, capsules, pills, solutions for injection, freeze-dried powers, or emulsions for injection, preferably tablets, pills, or freeze-dried powders. 13. The pharmaceutical composition according to claim 12, which is prepared by the following steps: 2,000 volume unit of water for injection use is added to 50.0 weigh unit of Rosmarinic acid to dissolve it; add NaOH until pH=5.5˜7.5; add 8 weigh unit of mannitol, and stir until it completely dissolves; pyrogen-free clear solution is obtained after ultrafiltration and 2 ml of the solution is filled into each 10 ml tube vials; lyophilisation process is carried out to obtain lyophilised preparations with 50.0 mg of Rosmarinic acid in each vial. 14. The pharmaceutical composition according to claim 12, which is prepared by the following steps: 100.0 weigh unit of Rosmarinic acid, 35.0 weigh unit of sucrose, 40.0 weigh unit of lactose, and 23.0 weigh unit of Sodium Carboxymethyl Starch are mixed well and passed through 100-mesh sieve; 3% of PVPK30 solution is added as needed to make a damp mass, which is then granulated through 20-mesh sieve; after dried at 60° C. for 3 hours, the granules are passed through 18-mesh sieve; 2.weight unit of magnesium stearate is added and mixed completely before compressed with shallow concavity to obtain tablets weighing about 200 mg and containing 100 mg of Rosmarinic acid each.
