Proangiogenic activity of plant extracts in accelerating wound healing - a new face of old phytomedicines.
Angiogenesis, the formation of new capillaries from pre-existing vascular network, plays an important role in physiological and pathological processes such as embryonic development, wound healing, and development of atherosclerosis. Extension of the circulatory network is also considered to be one the most important factors during cancerogenesis. Inhibition of angiogenesis may lead to inhibition of tumor growth whereas stimulation may improve wound healing. Research achievements suggest the use of plants and their extracts as potential therapeutic agents with pro- or antiangiogenic activity. Since the anticancer and antiangiogenic properties of many phytomedicines have been amply reviewed elsewhere this paper will focus on the treatment of vascular insufficiency in wound healing. Globally accepted herbal drugs are thought to be safe and effective, however, there is a need for more evidence-based confirmation in controlled and validated trials. Among the most frequently studied proangiogenic phytochemicals are ginsenosides from Panax ginseng, beta-sitosterol from Aloe vera, calycosin from Radix Astragali, and extracts from Hippophae rhamnoides L. and Angelica sinensis.
