1. Anti-tumor: Curcuma oil preparations can significantly inhibit and damage the growth of ehrlich ascites tumor cells, L615 leukemia of 615 inbred mice, ascites liver cancer cells and other tumor cells in vitro [1]. Intraperitoneal injection of 100% curcuma injection 0.3-0.5mL to mice had a good effect on sarcoma S180 and the inhibition rate of more than 50%. Monomer from the volatile oil of Curcuma, subcutaneous injection of 75mg/kg curcumol and curdione had a higher rejection rate on mice sarcoma S37, cervical cancer U14 and ehrlich ascites carcinoma (FCA). At the electron microscope, nucleus-cytoplasm ratio of the treatment group tumor cell reduced and nuclear shape tend to be normal. Chromatin, nucleoli and chromatin granules reduced, so curcuma can inhibit the murine sarcoma cells metabolic [2]. Curcumol and curdione can markedly damage Ehrlich ascites tumor cells in vitro and to its degeneration and necrosis [3]. Different concentrations of Curcuma oil injection had significant and direct damaging effects on tumor cells, fast and strong. The more tumor cells, the more dose concentration needed to kill 90% of these tumor cells [4]. Anticancer effect of Curcuma both the direct effect and the host immune response [3, 4]. With the clinical intratumoral injection treatment of cervical cancer by curcuma oil, tumor tissue necrosis, local lymphocyte infiltration, in some cases tumor disappeared and cervical smooth, that curcuma can directly kill rumor cells. In the biopsy saw intensive small lymphocytes around the cancer cells, a lot of sinus tissue proliferation in the lymphatic sinuses and blood lymphocytes significantly increased, these prompted valid cases had significant immune response [5]. Experiments showed that the EGA and L615 cell vaccine dealed with curcuma for active immunization, can really make a part of the animals to gain a significant protective effect [6, 7]. Further studies have shown that active immunization with the protective effect of curcuma L615 tumor strains had certain specific, because curcuma L615 tumor immune animals can not produce the effect of cross-protective immunity on the L615 (a new sarcoma leukemia of 615 strains mice). The Curcuma tumor immunohistochemistry animals who had significant inhibition of L615, though can withstand the repeated attacks of the L615 cells at a numnber of 105-3×107, died in L759 tumor cells at a number of 3×105 [8]. This protective immunity effect has a certain stability, once established, can be maintained for a long time (10-13 months), but can not be passed to offspring. Because the vast majority (93/94) of its offspring can not withstand the attacks of 105-3×107 L615 cells, all of them died in typical L615 leukemia and the average survival time had not been seen to extend, that the immune protective effect of parental generation is acquired and can not be passed to offspring [9]. Experiments showed that used a purely female T-739 mice to observe curcuma oil effect on the radiation sensitizing effect of the lung adenocarcinoma (LA-795), curcuma oil by intraperitoneal injection combined irradiation group had a more significant tumor growth delay effect than the alone radiation group, can increase the radiation treatment by 42% to reach moderate sensitizing effect [10]. Curcumol significatly inhibited the growth of MCF7, OV-UL-2, MM231 and HeLa cells and the best concentration of curcumol to inhibit the growth of tumor cells was 50μg/mL. Curcumol can markedly inhibit the RNA synthesis of MCF7, MM231 and HeLa tumor cells but had no impact on the growth of normal breast cells MCF12a and MCF10a. Curcumol can inhibit the proliferation of MCF7, MM231, HeLa and OV-UL-2 cells in vitro and can also inhibit the RNA synthesis of MCF7, MM231 and HeLa cells [11]β-elemene as terpenes extracted from WenEzhu and can induce a variety of tumor cell apoptosis. K562 cells processed by β-elemene showed the typical manifestations of apoptosis, such as pyknosis, formation of apoptotic bodies, agarose gel electrophoresis DNA ladder, in situ end labeling positive and so on [12, 13]. Apoptotic cell incidence was positively related to the processed concentration and time of elemene, further examined by flow cytometry found the crescendo of the apoptotic peak. At the see time observed that propidium iodide (PI) staining positive necrotic cells were less and did not increase with the improved drug concentration and extended action time. This indicated that the main effect of elemene on human leukemia K562 cells was to induce apoptosis. In addition, curcuma oil injection can inhibit RL-952 in vitro. Light and electron microscopy observation of morphological changes of cancer cells found that the inhibition rate of curcuma oil injection on RL-952 was time-dose dependent. Under light microscope can see cancer cells nuclear condensation and a large number of vacuoles in cytoplasmic. TEM can see obvious swelling of organelles in the cytoplasm, mitochondria dark thickening, cell chromatin fracture and agglutination. This showed that curcuma oil injection in the in vitro effects in human endometrial carcinoma cell line RL-952 may inhibit cancer cell proliferation by non-apoptotic programmed cell death [14]. Application elemene wiht radiation therapy for bone metastases, compared with radiotherapy alone, the efficiency was greatly improved and pain was significantly shortened. Immune Indexes CD3+, CD4+, CD4+/CD8+, IgA, lgM and IgC markedly improved, confirmed the elemene was an effective anticancer drug [15].

2. Anti-early pregnancy: Curcuma rhizomes ethanol extract and its active components (monoterpenes and sesquiterpenes compounds) in rats and mice had very significant effect of anti-early pregnancy, certain anti-implantation effect on the dog. Curcuma oil had the most significant terminating pregnancy, mice intraperitoneal injection and subcutaneous injection of 600-900mg/kg curcuma oil, the effect of anti-implantation and anti-early pregnancy was 70% to 90%, rabbit intraperitoneal injection of 80mg/kg curcuma oil, the anti-implantation effect was 80%. Vaginal injection 400mg/kg, the anti-implantation effect was 100%. Generally 2 to 5 days after pregnancy of administration, embryonic death, absorption or inhibit the implantation of embryos, while 7 to 10 days fater pregnancy of administration was causing a miscarriage or stillbirth. Volatile oil by the subcutaneous, abdominal and vaginal delivery were certain to stop pregnancy but the onset speed was different, intraperitoneal injection was the fastest, vaginal delivery was the slowest and intraperitoneal injection amount was five times less than the amount of vaginal delivery [16]. Fed mice with curcuma decoction also can stop pregnancy [17, 18]. Curcuma oil terminated pregnancy by preventing the embryos implantation to stop growing. Atrophy degradation embryos are free in intrauterine, some embryonic cell died after implantation and in the process of being absorbed [16].

3. Antiviral and antibacterial: Curcuma volatile oil in vitro can inhibit the growth of Golden yellow staphylococcus, the VI hemolytic streptococcus, E. coli, Salmonella typhi, Vibrio cholerae, etc. [19]. Xindeli measured the in vitro inhibition of curcuma oil and erythromycin on the mycoplasma pneumoniae local strain. In vitro experiment showed that the minimum inhibitory concentration (MIC) of curcuma oil on mycoplasma pneumoniae local strain was 2.5μg/mL and the MIC of erythromycin was 0.025μg/mL. Combined curcuma oil with erythromycin, their MIC were 1.25μg/mL and 0.00625μg/mL, that curcuma can inhibit mycoplasma pneumoniae local strain and had better effect when combine with erythromycin [20]. Curcuma oil on influenza virus A3 and adenovirus 7, the median effective concentration (IC50) were 0.0008μg/mL and 0.0004μg/mL, the therapeutic index (TI) were 15 and 30, that curcuma oil had a certain inhibition of influenza virus A3 and adenovirus 7 [21]. Curcuma soft capsule 160, 80 and 40mg/kg by intragastric administration can treat FM1 and RSV induced mouse pneumonia, significantly reduced lung index and reduced mortality. Curcuma oil and glucose injection may have a effect of preventing mumps brain [22]. In addition, GuangxiEzhu oil had a strong antifungal activity and can inhibit the spore germination of plant pathogenic fungi and the growth of mycelium. The MIC curcuma oil 6.25mL/L can significantly inhibit the spore germination of plant pathogenic fungi and the growth of mycelium. Rate of half inhibitory (IC50) showed that GuangxiEzhu had the strongest inhibitive effect on loose red blight bacteria and the weakest effect on fusarium graminearum. Electron microscope observation of hyphae cross-section showed that mycelial cell walls disappeared and protoplasm disintegrated. The results showed that GuangxiEzhu had the potential for the development of biological pesticides [23].

4. Elevated white blood cell: Intraperitoneal injection of 10mL/kg curcuma oil and 10mL/kg 0.3% curcumol for 8 days can significantly confront one time intraperitoneal injection of 150mg/kg cyclophosphamide induced leukopenia and promote leukocyte rebound, that curcuma can increase leukocyte in a certain level [24].

5. Effect on cardiovascularCurcuma was the best blood circulation drug to increase arterial blood flow,  blood flow peak increase of 252%, after 10 minutes, blood flow increased by 36.0%, vascular resistance decreased by 66.4%. Intravenous infusion of curcuma oil to treat thromboangiitis obliterans patients with blood stasis, with the improvement of clinical symptoms of these patients, limb blood flow significantly improved [1].

6. Hepatoprotective: Curcumol extract and volatile oil can reduce the CCl4 and TAA induced mice ALT improvement, decrease BSP retention and corresponding liver tissue lesions [26]. In addtion, cultivating HSC-T6 cell with different concentration of colchicine, turmeric oil, curcumol, β-elemene and curcumin and found that curcuma oil and curcumol were in HSCT6 cell 24 hours and 12 hours can lower the expression of gene TMPZ, L-6, TGF-p and p450a. From the genetic level, these results reveal the antifibrotic mechanism of curcuma active ingredients curcuma oil and curcumol [27].

7. Effect on acute renal failure: Subcutaneous injection of 50% glycerol saline 1mL/kg to rabbit can cause acute renal failure scorpion, visible dark purple renal swelling increased in the control group. Low magnification intravital microscopy observation can see more dark purple strip vascular stasis. Capillary blood flow stagnation or slow down, intravenous injection of 4mL/kg curcuma injection every day, 3 days later cannot see kidney swelling, dark lightening or had returned to normal and capillary blood flow accelerated. Rabbits after injection of glycerol about 12 hours red sauce urine occurred, urine output was significantly reduced, and some anuria, mental dejected, did not eat, died within 24 to 48 hours. Curcuma group increased urine after 24 hours, though the urine was red sauce, 48 to 72 hours later the urine returned to the pale yellow and no death [28].

8. Inhibition of platelet aggregation and antithrombotic: Gavage of 9.0g/kg curcuma water extract to rat every day, 7 days in total can significantly inhibit the ADP induced platelet aggregation, lower blood viscosity and shorten red blood cell electrophoresis time. Intravenous injection of 1.13g/kg water extraction and alcohol precipitation injection can markedly inhibit thrombosis in rat [29].

9. Analgesic and anti-inflammatory: Fed mice with 200mg/kg WenYujin benzine can significantly inhibit abdominal inflammation caused by acetic acid. Intraperitoneal injection of 200mg/kg WenYujin benzine can markedly inhibit burn local edema. Intraperitoneal injection of 100mg/kg can significantly inhibit croton oil-induced ear inflammation. Intraperitoneal injection of 75mg/kg benzine for 7 days can markedly inhibit subcutaneous granuloma proliferation [30]. In addition, different curcuma pieces had significant inhibition on xylene-induced ear edema and increased capillary permeability induced by acetic acid [31].

10. Effect on digestive system: The study found that 25.0% curcuma water decoction can improve gastric electrical rhythm disorders of functional dyspepsia rat caused by irregular eating and dilute niacin [32]. Isolated rabbit intestinal experiment found that low concentrations of curcuma increased intestinal tension but high concentrations made bowel diastolic [25].

11. Effect on hemorrheology: Different curcuma processed products all had the effect of inhibiting platelet aggregation, anticoagulant and regulating blood rheology [33]. In addition, curcuma injection in the treatment of diabetic retinopathy with good effect [34].

12. Others: Curcuma oil can significantly prolong the incubation period of mice semicarbazide convulsions, indicated that Curcuma oil may affect the brainstem neural function to improve the cortical excitability threshold to fight against epilepsy [35]. Curcuma oil bolt and Yikancuo made of water-soluble compound suppository had a strong effect on fungi and alcohol mother bacteria, and can diminish inflammation, stop pain, promote blood circulation and enhance the immune capacity [36]. Different curcuma oil cream can significantly inhibit the mitosis and proliferating cell nuclear antigen expression of  mouse vaginal epithelial cells of mouse tail scale epidermis rat vaginal epithelial experimental model, promote the formation of the mouse tail scales of the granular layer. This indicated that curcuma oil cream for the topical treatment of psoriasis of moderate efficacy drug and its mechanism may be inhibition of keratin-forming cells proliferation and promote keratinocyte normal differentiation [37].

13. Process in vivo: Intragastric administration of 3H-curcuma can be absorbed quickly and completely, can be measurd in 5 minutes if fed rat, reached the peak in 15 minutes and last about 1 hour, half-life 33 minutes for t1/2a and 12.5 hours for t1/2β. The liver and kidney concentration was 2 to 2.5 times higher than other organizations in vivo distribution, and can pass through the blood-brain barrier, mainly the urinary excretion and bile excretion, there was the phenomenon of enterohepatic circulation [30].
