Wound care using honey is still considered beneficial, and medical opinions suggest it can help reduce bacteria in wounds.
Yes, honey is one way to treat chronic wounds. An osmotic effect of honey disrupts the cell walls of bacteria and kills them. When gram-negative bacteria in particular are killed, endotoxins are released into the wound and can cause inflammation and delay wound healing. There is no data available to compare the effectiveness of honey and Sorbact. Ultimately, your client will need to compare the two products themselves. I strongly recommend that you agree on how you will measure the success of each product in terms of reducing signs of infection. If you agree on wound size reduction instead, you are not excluding other wound healing factors from this comparison. MMPs, moisture management, off-loading, compression all have an impact on wound healing.
