Background and aim: Wounds are the loss or damage of some body tissues. The wound healing process which then occurs in damaged tissue can be divided into three phases, namely the inflammatory phase, the proliferation phase and the phase of remodeling, which is the re-modeling of the tissue. One of the nutritious medicinal plants used by the community is turmeric (Curcuma longa) is one of the medicinal plants that has benefits and uses quite a lot. The main compounds contained in turmeric rhizome are essential oils and curcuminoids. Curcuminoid has antiinflammatory, antitumor prometer, antioxidant, antimicrobial and antiviral effects. This study aims to determine the effect of topical administration of turmeric (Curcuma longa) powder on wounds in white rats (Rattus novergicus). Materials and methods: Research with the title Effectiveness Test of Giving Turmeric (Curcuma longa) Powder on Wound Healing in White Rats (Rattus novergicus) is a type of experimental research with clinical trial design to determine whether turmeric can heal wounds in white rats. Results: From the results of the data analysis showed a significant comparison between turmeric
(Curcuma longa) powder and 0.9% NaCl solution. But based on the assessment of the reduction in wound length using a graph there is a comparison between the two. Where wound healing in the group given turmeric (Curcuma longa) powder was slower than the group given 0.9% NaCl solution. Conclusion: Giving turmeric (Curcuma longa) powder is effective in accelerating wound healing but slower when compared with 0.9% NaCl solution in incisions.
