Biofield Effects and Biophysics

Royal Jelly (RJ) is widely consumed in diets throughout the world due to its beneficial effects: antioxidant, antitumor and anti‐inflammatory. We have investigated the role of RJ in the development of TNBS colitis in mice. Colitis was induced by a rectal instillation of TNBS at 0.1 mL per mouse. Intestine samples of the animals orally treated with RJ (100, 150, and 200 mg/kg) were collected for antioxidant assays (GSH and GSH‐Px), proinflammatory protein quantification (COX‐2 and NF‐ κ B), and histological analyses. RJ 100 mg/kg maintained GSH levels and increased the activity of GSH‐Px, downregulated key inflammatory mediators (COX‐2 and NF‐ κ B), and decreased the lesions caused by TNBS as shown by the histological analyses. In conclusion, RJ showed anti‐inflammatory and antioxidant properties in experimental colitis, resulting in the amelioration of the macroscopic and histological analyses. These results corroborate with the RJ supplementation in diets.
