For worms: I found this REALLY affective and it got rid of my worms in 2-3 days.
You get 2 table spoons of body cream that you often use to moisturise your body.
A small squirt of hand sanitizer. (The more you add the more effective it'll work, but if using on your child only do a small amount since the hand sanitizer can cause stinging if too much is added)
And 1/2 tea spoon of paw paw ointment.
Melt the paw paw cream in the microwave for 5 seconds and add to the cream and mix thoroughly.
Then proceed to add the hand sanitizer into your mixture.
Every morning and night put some cream around the anus, this kills the eggs and reduces itchiness.
Soon, the worms will go away.
I advise also eating garlic cloves raw as well.
