Radiation therapy contributes to a significant increase in bone osteoporosis and skin loss. Various natural health products might be beneficial to reduce bone and skin alterations. Curcumin (CUR) medicines derived from natural plants have played an important role in health care. This study aims at synthesizing and evaluating the performance therapy of CUR‐encapsulated bioglass–chitosan (CUR–BG–CH). In vitro , the antioxidant assay was evaluated by using 1,1‐diphenyl‐2‐picrylhydrazyl free‐radical (DPPH) scavenging and the nitroblue tetrazolium reduction. The CUR–BG–CH antimicrobial effects were tested in liquid media. In vivo , after rat 60 Co γ‐radiation, the tissue wound‐healing process was studied by grafting CUR and CUR–BG–CH in femoral condyle and dorsal skin rat tissue. The antioxidant studies indicated that CUR–BG–CH quenches free radicals more efficiently than unmodified CUR and had effective DPPH (91%) and superoxide anion (51%) radical scavenging activities. The CUR–BG–CH biomaterial exhibited an important antimicrobial activity against Staphylococcus aureus . The histomorphometric parameters showed amelioration in CUR–BG–CH‐treated rats. An improved mechanical property was noticed (33.16 ± 5.0 HV) when compared with that of unmodified CUR group (23.15 ± 4.9 HV). A significant decrease in tumour necrosis factor‐α cytokine production was noted in the CUR–BG–CH rats (90 pg/ml) as compared with that of unmodified CUR group (240 pg/ml). The total amount of hydroxyproline was significantly enhanced (33.5%) in CUR–BG–CH group as compared with that of control. Our findings suggested that CUR–BG–CH might have promising potential applications for wound healing. Copyright © 2015 John Wiley & Sons, Ltd.
