A guar gum hydrogel carrying 1 mg each of seven mushroom extracts, including wood ear (Auricularia auricula), porcini (Boletus edulis), cordyceps (Cordyceps sinensis), shiitake (Lentinula edodes), turkey tail (Coriolus versicolor), reishi (Ganoderma lucidum), and snow fungus (Tremella fusiformis), was tested on 10 mm full-thickness wounds in rats. Wounds were checked on days 0, 5, 10, 15, and 20, and the mushroom-hydrogel site was described as “perfectly healed” by day 20 with no visible blood stain, pus, or inflammation compared with slower saline healing. The sample size was only 2 rats per group, though, so these results require a grain of salt.
