Gangrene
Death of body tissue due to loss of blood supply (dry gangrene) or bacterial infection in an oxygen-deprived wound (wet gangrene) — requiring urgent medical care and aggressive supportive treatment.
📝 Summary
In short: Death of body tissue due to loss of blood supply (dry gangrene) or bacterial infection in an oxygen-deprived wound (wet gangrene) — requiring urgent medical care and aggressive supportive treatment.
Common causes: Dry: blocked blood flow from frostbite, hardening of arteries, poor circulation, Raynaud's disease, diabetes, injury, or blood clot; Wet: infected wound with no oxygen supply; bacteria produce gas in tissues; Any condition that severely reduces circulation to an area.
First thing to try: Consult a physician — gangrene requires medical treatment
See a doctor if: Immediately for any suspected gangrene — this is a medical emergency, especially wet gangrene.
🌿 Overview
Dry gangrene is caused by stoppage of blood flow, most often in fingers, toes, nose, or ears — caused by frostbite, arteriosclerosis, Raynaud's disease, or diabetes. Without treatment, the gangrenous area must be amputated, but the person will survive. Wet (gas) gangrene is caused by an infected wound and kills within days if untreated — the person goes into shock. Gangrene is the advanced condition of blood poisoning; it will not develop in a person with good circulation and clean blood.
Common signs
- Dry gangrene: skin darkens and becomes dry, shrivels, and eventually sloughs off; dull aching pain, coldness, and eventual numbness
- Wet gangrene: skin progresses from pink to deep red to gray-green or purple; infected wound, shock if untreated
- Both: skin darkens and dies

- Chelation therapy (EDTA) — clinically proven to help with gangrene caused by arteriosclerosis
- Carrot juice daily; green drinks and chlorophyll; drink lots of water
- High-protein diet to rebuild tissue; kelp to strengthen the thyroid
- Keep walking or massage the area (usually the legs) to improve circulation
- Cool baths to the extremity or whole cool baths; add 1 Tbsp. chaparral teaA warm drink made by steeping herbs in hot water. How to make a tea → or apple cider vinegar per quart of water
