For pinworms, a probiotic drink called water kefir - you can get the "grains" from someone who grows this (like kombucha) and start drinking a small amount and work up to a litre or more a day over time. The good bacteria will take care of the worms and make you so alkalized that they can't survive.
I started drinking kefir to heal my gut microbiome and passed a bunch of these worms in my stool. I'm still using kefir and working on getting rid of them, but kefir really got the ball rolling.
