I started to get a little patch of ringworm from my cat. I put minced garlic on the spot for about 5 minutes and then rinsed it off. It will burn a bit. The next day the site was red but went away quickly in about 2-3 days. It was completely gone and didn't come back.
Apply some pickle juice with a cotton ball till it clear it completely.
Use regular notebook paper. 3 sheets are usually sufficient. Burn the paper in a plate, discard ashes and scrape up the brown residue while it is still warm and rub into affected area. This has worked for me on two different occasions over the past 50 years.
Get some tea tree oil and rub it on it three or four times a day. It works trust me
You can use Tinactin for ringworm. It is intended for jock itch, but it works for ringworm also. Just rub the salve over the ringworm to cover it each day and it dries up within one week.
All you need is to cover infected area with fingernail polish clear or colored.
I learned this from my high school science teacher and it works 100% of the time. Cover the ringworm with nail polish. It doesn't matter what color but clear is the least noticeable. The ringworm needs oxygen to survive and cannot if it is covered with nail polish. If it starts to crack because of movement just add some more polish. It will be gone in days!
Rub the ringworm vigorously to release the puss in the bumps surrounding the ringworm. Which is what causes it to spread. Apply hydrogen peroxide to the ringworm and let it air dry. It should develop scabs in 4-8 hours. If the ringworm still itches apply blue star ointment. Trust me, this works. I have two little kids who always gets ringworm's from school.
If you know what the start of it looks like before it gets out of hand. do the the following remedy. Get a beer cap and pour apple cider vinegar in the cap. Place an old penny in the cap and let it sit overnight. You will see green fungus..rub the penny on the tiny spot and it will go away in 2 days. Repeat twice in a row if the need be.
