Steps
Step 1: Find Plant in Physica
Match ailment to Hildegard Physica plants (Books I-IX: Plants, Elements, Trees, Stones, Fish, Birds, Animals, Reptiles, Metals).
Common Ailments → Physica Plants:
┌─────────────────────┬──────────────────────┬────────────────────┐
│ Ailment │ Primary Plants │ Physica Reference │
├─────────────────────┼──────────────────────┼────────────────────┤
│ Digestive upset │ Fennel, Yarrow, │ Book I, Ch. 1, 61 │
│ (cold pattern) │ Ginger, Galangal │ │
├─────────────────────┼──────────────────────┼────────────────────┤
│ Respiratory │ Lungwort, Elecampane,│ Book I, Ch. 95, 164│
│ congestion │ Hyssop, Anise │ │
├─────────────────────┼──────────────────────┼────────────────────┤
│ Skin inflammation │ Violet, Plantain, │ Book I, Ch. 34, 28 │
│ (hot pattern) │ Yarrow, Marigold │ │
├─────────────────────┼──────────────────────┼────────────────────┤
│ Nervous agitation │ Lavender, Lemon balm,│ Book I, Ch. 40, 123│
│ │ Chamomile, Valerian │ │
├─────────────────────┼──────────────────────┼────────────────────┤
│ Joint pain │ Comfrey, St. John's │ Book I, Ch. 21, 158│
│ (cold/damp) │ wort, Nettle, Birch │ │
└─────────────────────┴──────────────────────┴────────────────────┘
Hildegard Selection Rules:
1. Temperature: match plant heat to condition
- Cold → warm plants (fennel, ginger, galangal)
- Hot → cool plants (violet, plantain, lettuce)
2. Moisture: match plant wet to imbalance
- Dry → wet plants (mallow, linseed)
- Damp → dry plants (yarrow, wormwood)
3. Temperament match: plant harmony with user constitution
4. Season: fresh in growing time, dried in winter
Got: One to three plants match pattern (hot/cold, dry/damp) and user constitution.
If fail: Unsure of pattern? Default gentle plants (fennel, chamomile, yarrow). Hildegard says suit most constitutions.
Step 2: Pick Prep Method
Choose extraction + delivery by ailment location, acuity, plant parts.
Preparation Methods from Medieval Tradition:
┌──────────────┬────────────────────┬──────────────────┬──────────────┐
│ Method │ Best For │ Duration │ Shelf Life │
├──────────────┼────────────────────┼──────────────────┼──────────────┤
│ INFUSION │ Aerial parts │ Acute conditions │ 24 hours │
│ (hot water) │ (leaves, flowers) │ Internal use │ refrigerated │
├──────────────┼────────────────────┼──────────────────┼──────────────┤
│ DECOCTION │ Roots, bark, seeds │ Chronic use │ 24 hours │
│ (boiled) │ Hard plant parts │ Deep ailments │ refrigerated │
├──────────────┼────────────────────┼──────────────────┼──────────────┤
│ TINCTURE │ Long-term use │ Chronic support │ 2-5 years │
│ (alcohol) │ Concentrated dose │ Travel-friendly │ │
├──────────────┼────────────────────┼──────────────────┼──────────────┤
│ POULTICE │ External wounds │ Acute topical │ Use fresh │
│ (crushed) │ Skin conditions │ Inflammation │ │
├──────────────┼────────────────────┼──────────────────┼──────────────┤
│ OIL INFUSION │ Massage, salves │ Skin/muscle care │ 6-12 months │
│ (oil carrier)│ External only │ Long-term │ │
└──────────────┴────────────────────┴──────────────────┴──────────────┘
Decision Tree:
- Internal + Acute → Infusion or decoction
- Internal + Chronic → Tincture or daily decoction
- External + Acute → Poultice
- External + Chronic → Oil infusion or salve
Got: Prep method matches plant part (aerial vs root), use case (acute vs chronic), route (internal vs external).
If fail: Uncertain? Default infusion — safest, most forgiving for beginner.
Step 3: Prep Remedy with Dosage
Do prep. Precise measure, technique.
INFUSION (for aerial parts: leaves, flowers):
1. Measure: 1 tablespoon dried herb (or 2 tablespoons fresh) per 8 oz water
2. Boil water, remove from heat
3. Add herb, cover (to preserve volatile oils), steep 10-15 minutes
4. Strain through fine mesh or cheesecloth
5. Dosage: 1 cup 2-3 times daily, or as specific ailment requires
DECOCTION (for roots, bark, seeds):
1. Measure: 1 tablespoon dried root/bark per 8 oz water
2. Combine in pot, bring to boil
3. Reduce heat, simmer covered 20-30 minutes (up to 45 for hard roots)
4. Strain while hot
5. Dosage: 1/2 cup 2-3 times daily (more concentrated than infusion)
TINCTURE (alcohol extraction, 4-6 week preparation):
1. Ratio: 1 part dried herb to 5 parts menstruum (40-60% alcohol)
2. Combine in amber glass jar, seal tightly
3. Shake daily, store in dark place for 4-6 weeks
4. Strain through cheesecloth, press to extract all liquid
5. Dosage: 15-30 drops (approximately 1/2 to 1 dropper) 2-3 times daily,
diluted in water or tea
POULTICE (fresh or rehydrated dried herb):
1. Fresh: Crush or chew herb to release juices, apply directly to skin
2. Dried: Rehydrate with hot water to paste consistency
3. Apply to affected area, cover with clean cloth
4. Replace every 2-4 hours or when dry
5. Duration: Acute inflammation (24-48 hours), wounds (until healed)
OIL INFUSION (for external salves):
1. Ratio: Fill jar 3/4 with dried herb, cover completely with oil
(olive, almond, or sunflower)
2. Method A (solar): Seal jar, place in sunny window 2-4 weeks, shake daily
3. Method B (heat): Place jar in water bath (double boiler), low heat 2-4 hours
4. Strain through cheesecloth, press herb matter to extract all oil
5. Store in dark bottle; use within 6-12 months
Got: Remedy done per method. Right herb-to-menstruum ratio + steep/extract time. Dosage clear for internal/external.
If fail: Too strong (bitter, burn)? Dilute half. Too weak (no effect after 3 days proper dose)? Up herb amount 50% next batch.
Step 4: Document Contraindications
Flag safety, drug interactions, populations who must avoid.
Common Contraindications by Plant Category:
EMMENAGOGUES (stimulate menstruation):
- Plants: Pennyroyal, Rue, Mugwort, Tansy, Wormwood

- Caution: Fair skin, history of skin cancer
GENERAL CAUTIONS:
- Pregnancy/Breastfeeding: Most herbs lack safety data; avoid unless
traditionally used for pregnancy (ginger, red raspberry leaf)
- Children under 2: Avoid all herbal preparations except gentle teas
(chamomile, fennel)
- Children 2-12: Use 1/4 to 1/2 adult dose, depending on age and weight
- Elderly: Start with 1/2 dose; may be more sensitive to effects
- Chronic illness: Consult healthcare provider before use
- Surgery: Discontinue all herbs 2 weeks before scheduled surgery
Got: All contraindications listed for chosen plants. Specific populations flagged (pregnancy, children, drug interactions).
If fail: Uncertain about contraindications? Tell user see qualified herbalist or healthcare provider first. Default: "Not for pregnancy, breastfeeding, or children under 12 without professional guidance."
Step 5: Safety Review + Integration
Last check + guidance for monitoring effects + health integration.
Safety Review Checklist:
- [ ] Plant correctly identified (botanical name confirmed)
- [ ] Preparation method matches plant part and condition
- [ ] Dosage is within traditional safe range
- [ ] Contraindications reviewed and documented
- [ ] User informed this is historical folk medicine, not medical advice
- [ ] Expected timeline for effect noted (acute: 1-3 days; chronic: 2-4 weeks)
Monitoring Protocol:
Days 1-3:
- Note any immediate reactions (digestive upset, skin rash, headache)
- If adverse reaction occurs, discontinue immediately
- Positive signs: Symptom improvement, increased energy, better sleep
Days 4-14:
- Assess effectiveness: Are symptoms improving?
- If no improvement by day 7 (acute) or day 14 (chronic), reassess plant selection
- If partial improvement, continue; full effect may take 2-4 weeks
Integration Notes:
- Herbal medicine works best in context: adequate sleep, whole foods diet,
stress management, and connection to nature
- Hildegard's remedies are not isolated pharmaceutical interventions —
they are part of a holistic health practice
- Record observations in a journal: date, remedy, dose, effects
- Seasonal adjustment: Some remedies are more effective in specific seasons
(warming herbs in winter, cooling herbs in summer)
Got: User has all info: remedy prep, dosage, contraindications, monitor plan, integration context. Safety disclaimers clear.
If fail: User uncertain about self-prep? Tell see trained herbalist first, then replicate home when confident.
Checks
- Plant from Physica with right heat/moisture properties
- Prep method matches plant part (aerial = infusion, root = decoction)
- Dosage given with frequency + duration
- Contraindications documented (pregnancy, drugs, conditions)
- Safety review + monitor plan done
- User told: historical folk medicine, not medical diagnosis/treatment
- Timeline for effect clear (acute vs chronic)
Pitfalls
- Wrong plant: Common name confusion. Always confirm botanical (Latin) name
- Over-extract: Boiling delicate aerial parts kills volatile oils. Use infusion (steep), not decoction
- Under-dose: Medieval preps often stronger than modern tea. Follow traditional ratios
- Skip contraindications: Pregnancy + drug interactions serious. Doubt = advise against
- Modern substitute for medieval: Hildegard plants = European medieval flora. Substitutes break temperament system
- Want pharmaceutical speed: Plant medicine slow. Acute: 1-3 days. Chronic: 2-4 weeks minimum
- Solo remedy focus: Hildegard medicine holistic. Works best with diet, prayer, rest, seasons
