Wellllll-- if she has parasites, vinegar is not going to be able to get them out alone.
Raw Apple Cider vinegar does help the stomach's hydrochloric acid balance when you have Irritable Bowel Syndrome, or Acid Reflux. Taking a Tablespoon a day in the morning will help this- as well as taking digestive enzymes after each meal.
parasites are encouraged to grow when we do things like eat meat and then drink lots of soda or other drinks with a meal-- diminishing our hydrochloric acid balance which would normally be allowed to kill parasite larvea on contact.
Unrefined Apple Cider vinegar is good as prevention- as well as raw garlic and oregano Oil drops each day.-- also Olive Leaf capsules or tincture.
Now to purge them out, there are lots of herbs that can do this- Dr. Hulda Clark 's herbs are the main ones known to tackle all types of worms. There are other herbs that also purge out worms- if you do a Google.com search, you'll find sites that list them-- so get your notepad and pen ready and start surfing!
Tell your mother that the raw apple cider vinegar is good as prevention- but not a cure once a person has worms- and most of us all have some type of parasite-- since we havnt used dewormers on a maintenance basis like they did in the olden times.
Besides, our modern chemicals actually enhance living conditions in our bodies for many parasites you can pick up right in America!
Show her the list of herbs- and all she has to do is look for them in capsule form, and take with water every morning and night.
I like to add Hyssop tincture with my doses- as it seems to really kill any hidden fluke worms that I didnt know I still had.
Colon Cleanses-- (she can take 1-2 capsules of Colon Clenz at night for this) or 2 capsules of Cascara Sagrada and maybe Slippery Elm with water will clean her out discouraging parasite nests.
Liver flushes are also important-- and will flush out many a parasite in her- especially the ones that strayed to the liver from leaving the intestines.
Slippery Elm is good for "Leaky Gut".
Good luck- and tell her its soooo much better to take care of yourself and clean yourself out now than to be dependendent on our current healthcare system when shes a little older.
