Various pharmacological studies have been carried out to evaluate the effects on the central nervous system of R. damascena. These assessed effects have been examined in different studies. It is seen that it has antibacterial effect against both gram-negative and gram-positive bacteria. It has been stated that it has beneficial effects on brain function. Awale et al.

The roses were kept in boiled water at 98 °C for 5 minutes and filtered at the end of the time. Total phenolic content, antioxidant capacity and total flavonoid determination were done in the samples which arrived at room temperature. When the results of the analyses were examined, the total amount of phenolic material, the total amount of flavonoids and the antioxidant capacity values of dry bud were found to be lower than dry leaves. In addition, there was a statistically significant difference between the varieties. Besides its pleasant smell, it also has antioxidant properties that rose tea can be an alternative to other herbal teas.
