What is gangrene?
Gangrene or "necrosis" which is death of tissue in this case, in a living human, is usually caused by bacterial infection or obstruction of blood flow to a particular area - particularly the hands and feet.
When the blood supply is cut off, the tissue becomes “necrotic” i.e. some of the tissue dies because there is no blood circulation available to provide tissues with nutrients and oxygen.
Predisposing factors include diabetes, peripheral vascular disease, smoking and frostbite.
Wheatgrass prevents amputation of gangrene of the foot
Because this patient had irreversible damage to his big toe (note that it is black in the other pics) amputation of the whole forefoot was considered because gangrene often spreads to adjacent tissue if the dead tissue is not removed.
Wheatgrass extract, which can quickly repair damage to the micro-circulation, (the tiny blood vessels crucial for maintaining the skin health) was applied to the affected area on alternate days.
In the two above photos, (Figures 2 and 3) blood supply to the wound (red coloration) has improved, a sign that healing is progressing. Amputation of the forefoot will now not be necessary. In the photograph below, the big toe has been amputated and the forefoot now has good blood circulation, the whole wound having healed well.
