Eat one crushed or mashed raw garlic clove each day until your boils heal to get the maximum antibacterial and anti-fungal benefits of garlic, according to James Balch and Mark Stengler, authors of "Prescription for Drug Alternatives: All-Natural Options for Better Health without the Side Effects."
Take 600 to 1200 mg daily of aged garlic extract if you don't want to eat raw garlic. The University of Maryland Medical Center recommends dividing the dose throughout the day. For example, take 400 mg of allicin at breakfast, lunch, and dinner for a total daily dose of 1200 mg.
Alternatively, you can take 20 mL of garlic oil. This is about 20 drops from a glass dropper. Some people prefer to take a liquid supplement of allicin instead of eating garlic or taking allicin tablets.You can take the dose from the dropper or add to a glass of water.
Apply a warm compress to the MRSA boil for 20 minutes to help open the skin's pores and aid in the drainage of pus from the wound, according to Gary Null, author of "The Complete Encyclopedia of Natural Healing."
Apply one clove of crushed garlic in the center of a 4x4 piece of cotton gauze topically until the wound heals. Crush garlic to activate the allicin, the healing component of garlic. Wait two minutes and mash the clove. Apply the mashed clove on the affected area and cover with a dry bandage. Change the bandage daily after bathing, and use a fresh garlic clove when changing the dressing.
A 2003 study conducted at the University of London found that people who were scheduled for surgery to remove tissue infected with MRSA were able to avoid surgery after treating the infected wounds with garlic preparations.
If you have a boil or wound that won't heal, seek medical attention. Garlic may cause an allergic reaction in some people, such as sweating, hives, swelling of the face, tongue or lips. Other side effects are possible. This is not a complete list.
Apply a heating pad on top of gauze to help with wound healing. Avoid hot water bottles as the weight of the water bottle may increase pressure and pain the area afflicted.
