I agree with JAB.  First of all, the injuries sound serious enough to warrant prompt medical attention and secondly, the suggestion to use silver, either ionic or colloidal, is an excellent one.  I actually prefer ionic for topical injuries.

Other than than, from my website and book:

Cuts

• Serious cuts require prompt medical attention!

• Pressure.  Apply pressure to the cut to help the blood clot.

• Lavender oil.  Apply lavender oil to cuts and scrapes. Application usually causes no pain, and the pain from the wound should disappear quickly. Lavender also speeds healing immensely and kills germs.

• Colloidal or ionic silver.  Apply the silver to cuts and scrapes. The application causes no more pain than plain water, but silver is a natural antibiotic, germ killing, antiseptic that causes speedy healing and helps rebuild tissues.

• Raw honey.  Apply raw honey and cover with a bandage. With a small cut, the pain from the cut is gone after about 30 minutes, but leaving this on overnight is even better. Raw honey has been used for over 2,000 years to prevent and heal infections. (Raw honey is available in most grocery stores.)  Raw honey applied and left on overnight to a small cut that becomes infected should eliminate both the pain and infection by the following morning.

• Tea.  Apply wet tea bags to the cut.  The tannins in tea help the blood coagulate faster.  Especially good for cuts inside the mouth.

• Hydrogen peroxide.  Also good for cuts inside the mouth.  Mix 50/50 with water and apply with a Q-Tip.  For external cuts, apply antibiotic ointment afterwards, for cuts inside the mouth, dab on milk of magnesia with a Q- tip.

• The antioxidant power that makes vitamin E so good for your heart also speeds the healing of minor cuts. Simply prick a vitamin E capsule with a sterile needle and squeeze the oil onto your cut at least three times a day. Cover it with a Band-Aid if it's a serious wound. Be sure to choose natural vitamin E (d-alpha tocopherol).  Research shows that it has more antioxidant power than synthetic vitamin E.

• Bromelain (and extract of the pineapple plant) helps speed healing tremendously.

• Mix one part powdered echinacea, one part powdered slippery elm and one part powdered cranesbill.  Add water to make a paste. Rub on the affected area and cover with a bandage or gauze.

• Garlic.  Garlic is a natural antibiotic.  Rub fresh garlic on minor cuts.
