Preparation Methods

Part of Herbal Medicine

A medicinal plant picked from the field is not yet medicine. The preparation method determines which active compounds are extracted, how concentrated the dose is, and how the medicine is delivered to the body. Choosing the right preparation for the right plant and the right ailment is a core skill of practical herbalism.

Why Preparation Matters

The same plant prepared differently can treat entirely different conditions. Chamomile as a tea soothes the stomach; as a steam inhalation it clears sinuses; as a poultice it reduces skin inflammation. The preparation method controls:

• Which compounds are extracted — some dissolve in water, some only in alcohol or oil
• Concentration — a tincture is far more concentrated than a tea
• Delivery route — internal (teas, tinctures) versus external (poultices, salves)
• Shelf life — a fresh tea spoils in hours; a tincture lasts years
• Speed of action — liquids absorb faster than salves; tinctures faster than teas

Teas and Infusions

The simplest and most common preparation. Hot water extracts water-soluble compounds — flavonoids, tannins, mucilage, vitamins, and some alkaloids.

Standard Infusion (for leaves and flowers)

1. Boil water and remove from heat
2. Add 1-2 tablespoons of dried herb (or 2-3 tablespoons fresh) per cup (250 ml)
3. Pour hot water over herbs
4. Cover and steep for 10-15 minutes (covering prevents volatile oils from escaping with steam)
5. Strain and drink while warm

Strong Infusion (medicinal strength)

For higher-potency medicine:

1. Use 30-60 g dried herb per liter of water
2. Steep for 4-8 hours (overnight in a covered vessel)
3. Strain and use within 24 hours

Decoction (for roots, bark, and seeds)

Hard plant materials do not release their compounds into still water. Decoction uses simmering to break down cell walls.

1. Chop or crush the roots/bark into small pieces
2. Add 30 g per 500 ml of cold water
3. Bring to a gentle boil
4. Reduce heat and simmer 20-40 minutes with lid on
5. Strain while hot, pressing the plant material to extract all liquid

Preparation	Best For	Steep/Cook Time	Strength
Standard infusion	Flowers, leaves	10-15 min	Mild
Strong infusion	Flowers, leaves	4-8 hours	Strong
Decoction	Roots, bark, seeds, mushrooms	20-40 min	Strong
Cold infusion	Mucilaginous herbs (marshmallow)	4-12 hours cold	Mild

Cold infusions work best for mucilaginous herbs like marshmallow root and slippery elm. Heat destroys the mucilage (the slimy, soothing compound). Soak in room-temperature water overnight for maximum mucilage extraction.

Tinctures

Tinctures use alcohol to extract a broader range of compounds than water, including alkaloids, resins, and essential oils that are alcohol-soluble but water-insoluble. Tinctures are concentrated, fast-acting, and store for years.

Making a Tincture (Folk Method)

1. Fill a clean glass jar one-third to one-half full with chopped dried herb (or two-thirds full with fresh herb)
2. Pour 40-60% alcohol (vodka, brandy, or distilled spirits) over the herb until fully covered with 2-3 cm extra
3. Seal tightly
4. Store in a cool, dark place for 4-6 weeks, shaking daily
5. Strain through cloth, squeezing out all liquid
6. Bottle in dark glass containers and label with herb name, date, and alcohol percentage

Dosage Considerations

Tinctures are concentrated. Typical adult doses:

Herb Potency	Single Dose	Frequency
Mild herbs (chamomile, lemon balm)	2-5 ml (40-100 drops)	3x daily
Medium herbs (echinacea, valerian)	1-3 ml (20-60 drops)	3x daily
Strong herbs (goldenseal)	0.5-1 ml (10-20 drops)	2-3x daily

Some medicinal plants are toxic in concentrated form. Never make tinctures from plants you have not positively identified and researched. When in doubt, start with well-documented, safe herbs like chamomile, peppermint, or elderberry.

Vinegar Tinctures

For situations where alcohol is unavailable, apple cider vinegar extracts many water-soluble and some alcohol-soluble compounds. Use the same method as alcohol tinctures but note:

• Vinegar extracts are weaker than alcohol tinctures
• Shelf life is 6-12 months (versus years for alcohol)
• Some alkaloids and resins will not dissolve in vinegar
• Suitable for milder herbs and nutritive preparations

Poultices

A poultice is fresh or reconstituted plant material applied directly to the skin. It delivers active compounds locally and provides moist heat or cooling, depending on application.

Fresh Poultice

1. Bruise or chew fresh leaves until they release juice (a mortar and pestle works well)
2. Apply the mashed plant material directly to the affected area
3. Cover with a clean cloth bandage to hold in place
4. Replace every 2-4 hours or when dried out

Reconstituted Poultice (from dried herbs)

1. Mix dried, powdered herb with enough hot water to form a thick paste
2. Spread on a clean cloth
3. Apply cloth-side to skin (herb paste touches skin)
4. Cover with a dry cloth and secure
5. Leave for 30-60 minutes or as directed

Common Poultice Applications

Herb	Applied For	How It Works
Plantain leaf	Insect stings, minor wounds	Anti-inflammatory, drawing
Comfrey leaf	Sprains, bruises, bone healing	Contains allantoin (cell growth)
Clay + charcoal	Infections, toxin drawing	Absorbs toxins, reduces swelling
Onion	Chest congestion	Volatile oils loosen mucus
Cabbage leaf	Joint swelling, mastitis	Anti-inflammatory

Salves and Ointments

Oil-based preparations for skin application. Salves deliver fat-soluble compounds and create a protective barrier over wounds.

Making an Herbal Oil (Base)

1. Fill a jar loosely with dried herb (must be completely dry — moisture causes mold)
2. Cover with carrier oil — olive oil, sunflower oil, or rendered animal fat
3. Cold method: Seal and place in a sunny window for 4-6 weeks, shaking daily
4. Hot method: Place jar in a pot of water (double boiler) and heat gently at 50-60°C for 2-4 hours
5. Strain through cloth and squeeze out all oil
6. The resulting oil contains fat-soluble plant compounds

Converting Oil to Salve

1. Warm the herbal oil gently
2. Add beeswax — roughly 30 g per 250 ml of oil (more wax = harder salve)
3. Stir until wax is completely melted and incorporated
4. Pour into small containers
5. Allow to cool and solidify
6. Test consistency — reheat and add more oil (softer) or wax (harder) as needed

Salve Variations

Ingredient	Amount per 250 ml oil	Effect
Beeswax	30 g (standard)	Sets the salve
Honey	1 tbsp	Antimicrobial, moisturizing
Pine resin	1 tbsp	Antiseptic, drawing
Vitamin E (if available)	A few drops	Preservative, skin healing
Essential oil (if available)	10-20 drops	Fragrance, added medicinal properties

Pine resin salve is one of the most useful wound preparations you can make. Collect resin from pine, spruce, or fir trees, melt into oil at low heat, add beeswax, and you have a naturally antiseptic, waterproof wound covering that promotes healing.

Syrups

Sugar or honey preserves water-based herbal extracts and makes bitter medicines palatable — especially important for treating children.

Basic Herbal Syrup

1. Prepare a strong decoction or infusion (double strength)
2. Strain thoroughly
3. Measure the liquid
4. Add an equal volume of honey or twice the volume of sugar
5. Heat gently while stirring until the sweetener fully dissolves
6. Do not boil — excessive heat destroys some medicinal compounds
7. Pour into clean bottles and seal

Shelf life: 3-6 months at cool room temperature; longer in a cold cellar. Add a splash of brandy or other spirit to extend shelf life to 1+ year.

Classic Remedies in Syrup Form

• Elderberry syrup — immune support during cold and flu season
• Thyme or horehound syrup — cough suppression
• Ginger-honey syrup — nausea, sore throat
• Wild cherry bark syrup — persistent cough

Steam Inhalation

For respiratory conditions — congestion, sinus infection, bronchitis.

1. Prepare a strong infusion of aromatic herbs (thyme, eucalyptus, peppermint, pine needles)
2. Pour into a wide bowl while steaming hot
3. Lean over the bowl with a towel draped over your head to trap steam
4. Breathe deeply through the nose and mouth for 10-15 minutes
5. Repeat 2-3 times daily

Keep children away from the steaming bowl — scalding is a real risk. For children, place the steaming bowl out of reach and let them breathe the ambient steam in a closed room instead.

Compress

A compress is a cloth soaked in a strong infusion or decoction and applied to the body. It combines the medicine with thermal therapy.

Hot Compress

Soak cloth in hot herbal liquid, wring slightly, apply to affected area. Cover with dry cloth to retain heat. Useful for muscle pain, cramps, congestion.

Cold Compress

Soak cloth in cooled or chilled herbal liquid. Apply to injuries, headaches, fevers. Witch hazel and peppermint make particularly effective cold compresses.

Common Mistakes

1. Boiling delicate herbs — flowers, leaves, and aromatic herbs lose volatile oils when boiled. Use infusion (steeping), not decoction (simmering), for these materials.
2. Using too little herb — medicinal teas need 2-3 times the plant material used in culinary teas. One pinch in a cup is a pleasant drink, not medicine.
3. Not covering during steeping — essential oils evaporate with steam. Always cover your cup or pot during infusion.
4. Using fresh herbs for oil infusions — water content in fresh herbs causes mold in oil within days. Always use thoroughly dried herbs for oil-based preparations.
5. Storing teas for later — water-based preparations spoil quickly. Prepare fresh daily. If you need shelf life, make tinctures or syrups instead.

Summary

Preparation Methods — At a Glance

• Infusion (steeping): best for leaves and flowers; 10-15 min covered steep
