One important feature of this study is that it measured the effect of cinnamtannin on endogenous stem cells, meaning the stem cells produced by the mice' own bodies, not injected ones. Therefore, cinnamon extract in a herbal formula or cream may help to speed wound healing without requiring a stem cell clinic within affordable distance. Cinnamon extract is stocked in my college's dispensary, so as a widely available herbal medicine, research supporting its use is always relevant and welcome. It is commonly prescribed for blood sugar imbalances, as it may slow absorption of sugar into the blood, so it is already seen as a "diabetes/prediabetes herb". However, because of this study being on a specific substance in cinnamon, perhaps a standardised extract would be most helpful in wound healing. We already have these for ginkgo and St John's Wort, where an extract is formulated to contain a specific amount of one or more phytochemicals. It is possible to select plants that produce higher amounts of certain phytochemicals, and breed them to get the ideal levels. I would like to see trials on human participants, but this study is a good start.
