Anecdotal evidence requiring further research

1.2 Active Compounds in Medicinal Plants

Understanding plant chemistry enables proper preparation and dosing:

Alkaloids

Nitrogen-containing compounds with potent pharmacological effects
Examples: berberine (goldenseal), quinine (cinchona)
Generally stable in dried form
Water-soluble, extracted via infusion or decoction
Narrow therapeutic window—careful dosing essential
Often responsible for antimicrobial and immunomodulatory effects

Glycosides

Sugar-bound compounds that break down during digestion
Examples: digitalis glycosides (foxglove), salicin (willow bark)
Water-soluble, found in infusions and decoctions
Some require heating to activate
Several show cardiovascular and anti-inflammatory properties

Tannins

Polyphenolic compounds with astringent properties
Found in oak bark, raspberry leaf, pomegranate
Water-soluble (extracted via infusion/decoction)
Reduce with prolonged heating (over 20 minutes)
Excellent for wound care, diarrhea, hemorrhage control

Flavonoids

Polyphenolic antioxidants
Examples: quercetin, hesperidin, anthocyanins
Water and alcohol-soluble
Anti-inflammatory, antihistamine, cardioprotective effects
Found in berries, citrus, tea, and many herbs

Essential Oils (Volatile Oils)

Aromatic hydrocarbons and oxygenated compounds
Examples: menthol (peppermint), carvacrol (oregano), thymol (thyme)
Volatile—lost with heat exposure above 40°C
Extracted via steam distillation, cold pressing, or solvent extraction
Highly concentrated—require careful dilution for safety
Potent antimicrobial, anti-inflammatory, and bronchodilating properties

Terpenes

Hydrocarbon backbone of essential oils
Examples: limonene, pinene, camphene
Responsible for many aromatic and antimicrobial properties
Found in resinous plants (pine, frankincense, eucalyptus)

Saponins

Soap-like compounds forming emulsions
Expectorant and mucolytic properties
Examples: found in licorice, soapwort
Support mucosal health in respiratory tract

Mucilage

Slippery, gel-like polysaccharides
Demulcent action—protective coating
Examples: slippery elm, marshmallow, plantain
Water-soluble; cold or warm water extraction optimal
Excellent for GI and respiratory irritation

1.3 Methods of Preparation

Proper preparation maximizes active compounds and ensures safety:

INFUSION (Tea)

Method: Pour boiling water (100°C) over dried plant material, steep 5-15 minutes
Best for: Leaves, flowers, delicate plant parts, volatile oils
Active compounds extracted: Flavonoids, volatile oils, some alkaloids
Dosing: 1 teaspoon dried herb per 8 oz water; 1-3 cups daily
Shelf life: 24 hours at room temperature, refrigerate for longer storage
Advantages: Simple, quick, preserves volatile oils better than decoction
Disadvantages: Does not extract minerals and tough plant material well

DECOCTION (Boiling)

Method: Simmer plant material in water 15-30 minutes, strain while hot
Best for: Roots, bark, seeds, tough woody plant parts, minerals
Active compounds extracted: Glycosides, alkaloids, tannins, minerals
Dosing: 1-2 teaspoons dried material per 8 oz water; 1-3 cups daily
Shelf life: 24 hours room temperature, refrigerate for longer
Advantages: Extracts minerals and tough plant material; more concentrated
Disadvantages: May reduce volatile oils and heat-sensitive compounds

TINCTURE (Alcohol Extract)

Method: Soak plant material in alcohol (typically 40% ethanol or higher) for 2-6 weeks
Best for: Roots, bark, resinous materials, long-term storage, concentrated dosing
Active compounds extracted: All types including alkaloids, glycosides, resins, essential oils
Dosing: 20-40 drops (1-2 mL) in water, 1-3 times daily
Shelf life: 3-5 years or longer with proper storage
Advantages: Excellent extraction; long shelf life; concentrated dosing; antimicrobial
Disadvantages: Requires alcohol; not suitable for people avoiding alcohol; slower preparation
Note: Can create glycerin-based tinctures for alcohol-free preparations (less effective extraction)

POULTICE (External Paste)

Method: Grind fresh or dried plant material with water to paste consistency, apply directly to skin
Best for: Acute inflammation, wounds, infections, pain, drawing infections
Active compounds: Direct topical delivery of all compounds
Preparation time: 5-10 minutes
Application: Apply 1/4-1/2 inch thickness, cover with cloth, change every 2-4 hours
Duration: 20 minutes to several hours
Common materials: Clay, plantain, calendula, comfrey, slippery elm
Advantages: Direct application; customizable; combines multiple herbs easily
Disadvantages: Messy; requires frequent changes; suitable only for external use

SALVE (Topical Ointment)

Method: Infuse dried herbs in oil (solar infusion or gentle heating), add beeswax to desired consistency
Best for: Long-term wound care, skin conditions, topical delivery
Oil base: Olive oil, coconut oil, jojoba oil, or other carrier oils
Wax ratio: 1 part beeswax per 4-5 parts oil
Shelf life: 1-2 years with proper storage (cool, dark location)
Common bases: Calendula salve, comfrey salve, plantain salve
Application: Apply thin layer, cover if necessary, reapply 2-3 times daily

Disadvantages: Slower preparation; requires beeswax; not suitable for very weepy wounds

ESSENTIAL OIL EXTRACTION

Steam distillation: Hot steam passes through plant material, cools and separates from water
Cold pressing: Mechanical extraction (citrus oils)
Solvent extraction: Using alcohol or other solvents
Yield: Very small amounts (500+ pounds fresh plant material yields 1 pound essential oil)
Concentration: 50-100 times stronger than whole plant
Safety critical: Never use undiluted on skin or internally without expert guidance

COMPRESS (Liquid Poultice)

Method: Soak cloth in hot infusion or decoction, apply to affected area
Best for: Pain, inflammation, bruising, swelling
Application: Apply as hot as tolerable, change as it cools, 15-30 minutes
Advantages: Combines benefits of infusion with topical delivery
Disadvantages: Requires frequent reheating

HYDROSOL (Floral Water)

Byproduct of steam distillation of essential oils
Contains water-soluble plant compounds and trace essential oils
Uses: Facial sprays, wound rinses, internal use (in small amounts)
Shelf life: 6-12 months refrigerated
Safer than essential oils for internal and delicate applications
