Permissive hypotension or hypotensive resuscitation[1] is the use of restrictive fluid therapy, specifically in the trauma patient, that increases systemic blood pressure without reaching normotension (normal blood pressures).
One of the advantages of using the green coffee bean extract is that the negative effects of coffee are avoided. The chlorogenic acid is thought to boost metabolism by changing the way glucose is taken up by the body. And it does contain caffeic acids, which give a boost to energy levels like regular coffee does. But unlike boiled coffee, green coffee bean extract contains no cafestol, which is a diterpene.
Green tea on its own, for example, has been shown to slightly increase metabolism, making it a possible aid to weight loss, but a separate study shows that metabolism is inhibited when milk is added.
