Herbal Preparation Used as Adjuvant Therapy on Diabetic Ulcers
Chronic foot ulcers occurring among diabetic patients are difficult to heal. The frequent elderly age with co-morbidities, vascular insufficiencies, peripheral neuropathies and super imposed infections, all contribute towards the chronicity and failure of treatment. Preserving the ulcerated limb is the patients' wish. On the other hand, an infected ulcer that never heals just unnecessarily prolongs suffering. Nevertheless, patients earnestly like to try all methods of healing before accepting amputation.
Objective:To determine whether a course of herbal preparation used as an adjuvant therapy for diabetic patients suffering from chronic foot ulcers may promote healing so that major leg amputation can be avoided.

|Official Title:||An Evidence Base Study on the Clinical Effects of Integrated Western Medicine and Traditional Chinese Medicine for Diabetic Foot Ulcer Treatment|
- Number of Participants With Limb Salvage [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]The number of successful limb rescued (without amputation).
- Tumour Necrosis Factor-alpha Levels in Serum [ Time Frame: Baseline and 4 week ] [ Designated as safety issue: No ]The state of inflammation at baseline and at 4 weeks after treatment. TNF-alpha are in value of serum level.
- Time of Ulcer Healing [ Time Frame: 24 week ] [ Designated as safety issue: No ]Time taken for maturation of granulation to enable skin grafting.
