1. Antibacterial, anti-virus: Chinese rose of gallic acid in vitro antimicrobial effect of antibacterial concentrations is 5 mg/mL [1]. The flavonoids kaempferol it contains is a broad-spectrum antibiotics, quercitrin also has a strong antiviral activity [2].

2. Antioxidant: Chinese rose extract has the effect of free radicals, the effect gradually increased with the increase in concentration of the extracts. Its clearance rate in proper sequence is 95% ethanol, water, 60% ethanol, ethyl acetate extract [3].

3. Diuretic: Chinese rose contained quercitrin expansion of the renal artery, increase in renal blood flow and diuresis [4].

4. Immune Enhancement: Chinese rose in the flavonoid constituents gate quercetin 0.01 ~ 0.001μg/ml within the concentration range can significantly promote the T-and B lymphocyte proliferation and enhances interleukin II (PGI2) production [5].

5. Inhibition of platelet aggregation: Quercetin may activate platelet cyclooxygenase, enhance vascular endothelial coverage of platelet thrombosis at the PGI2 biosynthesis, inhibit the platelet aggregation, resulting in vasodilatory role against thrombosis and inhibit the platelet activation factors leading to platelet aggregation [6].

6. For the treatment of cerebral thrombosis :Quercetin can reduce vascular permeability used in the treatment of cerebral thrombus, arterial sclerosis and myocardial infarction.

7. Anticancer:Quercetin has not only a variety of carcinogens, tumor promoters and mutagens antagonism, but also a variety of malignant cells such as Ehrlich solid tumor cells, Hela cells, human breast cancer cells human glioma cells, human pharyngeal cancer cells, a variety of cancer cells, colon cancer cells and ovarian cancer such as inhibition of growth [8].

8. Protection of islet cell injury by exogenous nitric oxide (NO): Chinese rose water extract can reduce exogenous NO damage isolated rat pancreatic islet cells NO, malondialdehyde release, to improve the level of superoxide dismutase ,significantly improves the survival rate of cells, the insulin secretion quantity , restrains DNA content reduced .For esternal NO cause of islet cell damage ,it has a very good protection effect.

1. Intramuscular injection callosity: treatment group with Yuejihuafen, paste and apply to callosity place, 2 ~ 3 times per day, 1 h per time .The control group was treated by temperature towel hot compress, 2 ~ 3 timesper day, 1 h per time. Three days as one courses of treatment, the treatment for2 courses. Results: treatment group total effectiveness was 97.5%, the controlgroup total effectiveness was 75%, the curative effect of treatment group wasbetter than control group(P<0.01) ^[1].

2. Diabetic gastroparesis: treatment group was treated by westernmedicine hypoglycemic therapy , on the basis of that, and was took Tangpikangcapsule ,three times per day, 4 capsules per time, take that in 30 minutesbefore meal. Control group was took  moshabbethai the force treatment, three times per day, 10 mg per time, take thatin 30 minutes before meal. Two groups  were treated all for 15 days, the treatmentgroup in 40 cases, 39 cases as control group. Results: the two groups aftertreatment gastrointestinal symptoms and fasting blood glucose, blood sugar 2 hpostprandial were significantly improved (P < 0.01), and the curative effectof treatment group was better than control group ^[2].
