History; Source

The hulls of black walnuts have been used historically by the Asians, as well as American Indian tribes to expel various types of worms.

Usually black walnut hulls are ground fresh and supplied as a powder in order to be included in various supplements.


It is thought that the high tannin content is responsible for the anthelmintic property of black walnut, although there are other constituents such as juglandin and juglone that may also be responsible.  The primary active constituent in Black Walnut is a naphthoquinone known as juglone.


The following protocol is a composite of the recommendations of Dr. Hulda Clark and Dr. William Lee Cowden, MD.  Stick to the program for 10-14 days, take 5-7 days off, then repeat for another 10-14 days.  CAUTION: All protocols are for adult dosage only and are generalized; dosages and conditions will vary with the individual.  Listen to your body; build up dosages slowly and carefully; only go at a rate you can tolerate.  Before beginning any treatment, consult a qualified health care professional.  This is especially important in the case of treating children, or if you are pregnant.

Bear in mind that if one member of a family is infected, other family members or persons living at close quarters frequently are too.  In the case of pinworms, this is almost always the case.

If you take the liquid extract, make sure the extract is made from fresh whole green hulls of black walnut.  You may also use black walnut capsules.  Take with water 15-20 minutes before a meal.

For black walnut hull capsules, this is what Dr. Cowden recommends:
Day 1: 2X daily, 1 capsule
Day 2: 2X daily, 2 capsules
Day 3: 3X daily, 2 capsules
Day 4: 3X daily, 3 capsules
Day 5: 3X daily, 4 capsules
Day 6: 3X daily, 5 capsules
Day 7: 3X daily, 6 capsules
Continue at 2 capsules 3X daily through to day 14.
During the second 10-14 day round, take 6 capsules 3X each day.

For black walnut hull extract, this is what Dr. Clark recommends:
Day 1: 4X daily, 1 drop mixed in water.  Space the drops 4 hours apart, starting in the morning.
Day 2: 4X daily, 2 drops
Day 3: 4X daily, 3 drops
Work up to 20 drops taken 4 times daily and continue at this rate until the treatment program is finished.

Wormwood works best when the full day's dosage is taken at one time, 15-20 minutes before a meal, says Dr. Cowden.  Here is his recommendation:
Day 1: 2 capsules
Day 2: 4 capsules
Day 3: 6 capsules
Day 4: 8 capsules
Day 5: 10 capsules
Day 6: 12 capsules
Day 7: 14 capsules.
Continue at 14 capsules until the course is complete.  Stay off wormwood during the same 5-7 days you're off black walnut, then resume at 14 capsules of wormwood daily for another 10-14 days.

Crush fresh cloves in a coffee grinder and fill "gelatin capsules" or "veggie caps" (size "00").  Fill the capsules at once and discard any left-over clove powder as it loses its potency quickly when exposed to the air.  You will need 117 clove capsules, says Dr. Cowden.

According to Dr. Cowden, this is the schedule to follow:
Day 1: 3X daily, 1 capsule
Day 2: 3X daily, 2 capsules
Day 3: 3X daily, 3 capsules
Then 3 capsules 3X daily through day 14.  Take capsules 15-20 minutes before a meal.  Stay off cloves the same days you are off wormwood and black walnut, then resume at 3 capsules 3X daily for another 10-14 days.

Some manufacturers provide a tincture containing all 3 of these herbs, which simplifies the procedure for people with a busy schedule.
