Tinctures
Part of Herbal Medicine
Making alcohol-based herbal extracts with a shelf life of 5-10 years for long-term medicine storage.
Why This Matters
Tea is effective medicine, but it lasts 24-48 hours before spoiling and requires fresh preparation each time. A tincture — the same herb extracted into alcohol — lasts 5-10 years with no special storage beyond keeping it in a sealed container. This transforms seasonal harvesting into a year-round medicine supply.
Alcohol dissolves a broader range of medicinal compounds than water alone: alkaloids, resins, essential oils, and glycosides that water extraction misses or captures poorly. This makes tinctures more potent per unit volume than teas for many herbs. A standard dose is 20-40 drops — easy to carry, precise to dose, and fast-acting (alcohol absorption begins in the mouth and stomach, faster than digested tea).
For any community building a long-term medical capability, tinctures are the core of the medicine chest. They represent the accumulated harvest of years, preserved and concentrated.
The Chemistry of Tinctures
Alcohol (ethanol) is the solvent. It dissolves:
- Alkaloids (pain compounds, stimulants, sedatives)
- Resins (antimicrobial, anti-inflammatory)
- Essential oils (aromatics, volatile medicinal compounds)
- Glycosides (heart, respiratory, immune compounds)
- Bitters (digestive stimulants)
Water-alcohol mixtures (hydroalcohols) extract everything water extracts plus the above. This is why 60-70% alcohol is ideal — strong enough to extract resinous and oily compounds, with enough water to capture water-soluble compounds as well.
Minimum effective alcohol concentration: 40% (80 proof) — adequate for most herbs. Optimal concentration: 60-70% for most tinctures. High-alcohol (80-90%): For resins, very dry material, or highly aromatic herbs. Low-alcohol or glycerin (non-alcoholic): For children, those avoiding alcohol. Less effective for resinous or alkaloid-rich herbs.
Making Alcohol for Tinctures
High-proof grain alcohol at 60-70% is the ideal tincture menstruum. In a non-modern context, this is produced by fermenting grain, fruit, or sugar and then distilling to increase alcohol concentration.
Source options:
- Distilled grain spirit (vodka equivalent or higher): Ideal. Neutral taste. 40% vodka works but 60-70% concentrated grain spirit is better.
- Strong fruit distillate (brandy, grappa): Works well. Flavor of the spirit becomes part of the tincture — not a problem.
- Diluted high-proof spirit: Take 95% grain alcohol (if available from distillation) and add water to reach target concentration.
Calculating dilution: To make 70% alcohol from 95% alcohol, use the formula: add water in the ratio of (95-70) / 70 = 0.357 parts water per part 95% alcohol. For every 100 mL of 95% alcohol, add 35.7 mL water to get approximately 70% alcohol.
Test alcohol strength (empirical method): 40% alcohol does not sustain a flame well. 50%+ sustains a flame briefly. 70%+ burns steadily. While imprecise, this gives a rough guide when you have no way to measure.
Standard Tincture Preparation
Materials
- Dried or fresh herb
- Alcohol at 40-70%
- Clean glass jar with tight lid
- Straining cloth (cheesecloth, clean linen)
- Dark glass bottles for storage (amber glass if available)
Ratio for Dried Herb
Standard ratio: 1 part herb by weight to 5 parts alcohol by volume (1:5 ratio).
Without a scale, this approximates to: Fill a jar loosely to the top with dried herb, then pour alcohol to cover completely with 2-3 cm above the herb level.
Ratio for Fresh Herb
Fresh herb contains water, reducing effective alcohol concentration.
Fresh herb ratio: 1 part herb by weight to 2 parts alcohol (1:2 ratio). Pack the jar firmly with fresh chopped herb and just cover with alcohol.
For high-water fresh material (fresh roots like valerian, fresh berries): Use higher-proof alcohol or dry the material first.
Process
- Prepare the herb. Dried: break or grind slightly to increase surface area. Fresh: chop finely to increase contact with alcohol.
- Fill the jar. Place herb in clean, dry jar.
- Add alcohol. Pour over herb, ensuring all material is submerged. Air pockets allow mold.
- Seal tightly. Label with herb name, alcohol type, concentration, date, and batch number.
- Macerate for 4-6 weeks. Store in a cool, dark location. Shake daily or every few days.
- Strain and press. After maceration, pour through cheesecloth. Wring the cloth firmly — the last pressed liquid contains the highest concentration.
- Bottle and label. Transfer to dark glass bottles. Label with same information as jar plus dose information.
- Storage: Cool, dark location. 5-10 years shelf life for most tinctures.
Dosing Tinctures
Standard adult dose: 20-40 drops (1-2 mL) in a small amount of water, 2-3 times daily.
Children: See dosage calculation article for Clark’s Rule. Generally 5-15 drops for children over 5, depending on weight.
Acute conditions: Dose more frequently — every 2-3 hours for the first day of acute illness. Reduce to 3 times daily as symptoms improve.
Chronic conditions: 2 times daily for weeks to months. Always take a 1-week break per month of chronic use to prevent tolerance buildup.
Dose measurement without a dropper: A standard pipette or small bottle with a narrow neck — tilt to drop. Standard drop is approximately 0.05 mL. 20 drops = 1 mL. Calibrate your specific dropper bottle by counting drops to fill a measured amount.
Key Tinctures to Prioritize
| Herb | Best Part | Shelf Life | Primary Use |
|---|---|---|---|
| Echinacea | Root (or flower) | 5+ years | Immune support, infection |
| Valerian | Root | 5+ years | Sleep, anxiety, muscle spasm |
| St. John’s Wort | Flower (fresh, peak bloom) | 5+ years | Depression, nerve pain |
| Elderberry | Fresh berries | 5+ years | Flu, immune |
| Willow bark | Inner bark | 5+ years | Pain, fever |
| Skullcap | Leaf/flower | 5+ years | Anxiety, nerve pain |
| Passionflower | Aerial parts | 5+ years | Anxiety, insomnia |
| Hawthorn | Berry or leaf | 5+ years | Heart support |
| Calendula | Fresh flowers | 5+ years | Wound healing, gut, skin |
| Dandelion root | Root | 5+ years | Liver, digestive support |
Troubleshooting
Tincture has developed mold (rare but possible): Discard. Usually caused by plant material not fully submerged. Prevent by keeping material under the liquid level.
Sediment in tincture: Normal. Shake before use. Fine plant particles settle over time.
Color change over time: Normal. Most tinctures darken with age. This does not indicate spoilage.
Alcohol smell has faded: May indicate seal failure and evaporation. Check lid. If very little alcohol remains, the tincture’s preservative power is compromised.
Weak effect: Either herb was low potency at harvest, alcohol concentration was too low, or maceration time was too short. Next batch: use fresher material, stronger alcohol, and allow 6 weeks maceration.
Make Tinctures at Peak Harvest
The best time to make a tincture is immediately after harvest, when plant material is at maximum potency. Fresh flower tinctures (St. John’s Wort, calendula) made within hours of harvest are significantly more potent than those made from dried material. For roots, dry them first — drying concentrates root compounds and reduces water content, improving extraction efficiency.
