Taking this information from School of Natural Healing by Dr. John R. Christopher, 25th edition. Chapter 3 anthelmintic herbs are discussed. It lists the herbs then mentions immediately the three most common worms found in the human body: thread or seat worms (Oxyuris vermicularis); round worms (Ascaris lumbricoides-lumbrici); and tape worms (Taeince-Taenia solium).
Other worms include hook worms and trichinella spiralis. These last two thrive on toxicity in the body.
Different parasites call for different remedies. The thread/seat worms (I've never heard of these) are easily expelled as they don't adhere to the intestinal wall and can be eliminated with an enema of aloe or ACV.
Round worms, the book states, should be treated with a three day cleanse and fasting drinking only one kind of juice and distilled water only. Also using the herb wormwood in small repeated doses. Probably using it in tincture form every four hours, 5-30 drops. I'd err on the side of caution with wormwood and not use 30 drops. Senna tea on the 4th day.
Haha, ready for more information? For tapeworms: They say use male fern or pomegranate as your anthelmintic to start. Use a tincture, capsules; then use lobelia sparingly. Lobelia can make you vomit. Meanwhile, eat foods the worms dislike: salted fish, onions, garlic, and pickles. It weakens the worms, they lose grip, you take the herbs, the worms are expelled. This information, though in Dr. Christopher's book, was from a Dr. Shook.
There is more information in this book of recipes and mixes of herbs to use for expelling/killing worms in the body. If you need more information I can look it up for you. Some of the herbs listed are not so easily found.
The late Dr. James Duke, PhD, formerly of USDA, wrote in his book, Green Pharmacy, that ginger, pumpkin, wormseed, garlic, papaya, pineapple, turmeric and clover were all beneficial in eliminating worms. Dr. Duke seemed like a very open minded guy about the wonders of plants and how they could heal us.
