Grape seed extract may help wound healing

Grape-seed extract may help skin wounds heal faster and with less scarring, a new study suggests. The extract seemed to aid wound healing in two ways: It helped the body make more of a compound used to regenerate damaged blood vessels, and it also increased the amount of free radicals in the wound site. Free radicals help clear potentially pathogenic bacteria from a wound.

Hyperbaric treatment on the cheap

Hand me a cheap plastic bag, an oxygen tank and some low-tech sensors and I’ll give you … well … I’ll give you them back. But a team from Sandia National Laboratory and a California company has combined the three into an inexpensive wound-healing device that the U.S. military says it plans to license for active and retired personnel. Think of it as a low-rent — but effective — hyperbaric chamber. But instead of costing $1 million to build and $1,500 per treatment, the whole shebang can be had for about $185.
