Based on our previous in-vitro and in-vivo studies, a new reformulated recipe of herbal medicine has been developed. In this proof-of-concept study, the investigators hypothesize that the novel recipe of herbal medicine will expedite healing of early foot ulcer by promoting vascularisation and granulation as well as modulating inflammatory response. Results will provide valuable insight and understanding of the application of TCM in the management of diabetic foot ulcer, in particular, the effect on angiogenesis and anti-inflammation. New intellectual properties will be developed and provide the foundation for future research. Such an integrated approach from bench to bedside will serve as a model platform for the development of TCM in Hong Kong.
