Black Walnut Hull Tincture Recipe

    In the fall, collect the green black walnut hulls recently fallen
    from trees. Only select hulls that have less than 50% black
    discoloration. The more green, the better. Do not use cracked
    hulls. The actual walnut is inside, but only the whole ball is
    used since the active ingredient is in the green outer hull.
    Black walnut hulls may look and smell like small limes.


  • Your largest stainless steel or glass (not aluminum, ceramic, plastic,
    enamel, or Teflon) pots or bowls.

  • Black walnuts in the hull, each one still at least 50% green, enough to
    fill the pot to the top.

  • Grain alcohol, about 50% strength, or regular vodka. Enough to cover
    the walnuts.

  • Vitamin C powder (capsules are fine)

    Caution:  Black Walnut Hulls can stain counter tops, clothing and may cause
    contact dermatitis. Handle carefully.


    Wash the walnut hulls carefully with water that does not have laundry
    bleach disinfectant.  

    Put them in the pot and cover completely with the alcohol or vodka.  
    Sprinkle on 1 tsp. vitamin C.  Cover with lid.  Let set for three days.  

    Add another tsp. vitamin C.  Use funnel to pour into glass bottles, preferably
    amber bottles. If amber is not available, store in a dark place. Better yet,
    store in freezer.

    Discard walnuts (squirrels love them!).  

    The vitamin C helps to keep the color green, as does the non-chlorinated
    water if you use grain alcohol. Potency is strong for several years if
    unopened, even if it darkens slightly.

    Walnut Tips

    When preparing the walnuts, wash only with cold tap water. Rinse with
    distilled, unfiltered water to remove all chlorine.  You may need to use a
    brush on areas with dirt. The pot of soaking walnuts should not be

    Reducing Exposure to Air Tips

    Exposure to air causes the tincture to darken and lose potency very quickly.  
    To reduce air exposure, fill the pot as much as possible while still keeping a
    snug fitting lid. It is better to put tincture in many small bottles rather than
    one large one in order to reduce repeated exposure to the air once opened.
    Store bottles in freezer for maximum potency.

    Grain Alcohol Tips

    If you cannot use vodka, there are several ways to make a 50% grain alcohol
    solution.  Some states in the US sell Everclear, 95% alcohol.  Mix this half and
    half with distilled, unfiltered, water.  Other states have Everclear that is
    76.5% alcohol. Mix this two parts Everclear, to one part water.  Do not use
    flask-size Everclear; it must be 750 mlor 1-liter.  Smaller bottles may have
    wood alcohol or isopropyl alcohol contamination.

    Dosage: Only take black walnut tincture under the direction of a licenced
    healthcare professional. Wormwood (artemisia annua or artemisia absinthe)
    as well as freshly-ground cloves are often recommended as part of the anti-
    parasite strategy.
