How To Harvest And Use Medicinal Plants Safely

Identification First

Always positively identify a plant before harvesting. Use a field guide or app like iNaturalist. Some poisonous plants look similar to medicinal ones. For example, poison hemlock resembles yarrow but is deadly.

Sustainable Harvesting

Take only what you need. Leave at least 70% of the plant population to regrow. For roots, harvest from large patches and replant some root pieces. Never harvest endangered species like wild ginseng without permits.

Cleaning And Storage

Wash plants thoroughly to remove dirt and insects. Dry them in a well-ventilated area away from direct sunlight. Store dried herbs in airtight glass jars in a cool, dark place. Most herbs last 1-2 years.

Preparation Methods

Tea: Steep 1-2 teaspoons of dried herb in hot water for 10-15 minutes
Tincture: Soak herb in alcohol (vodka or brandy) for 4-6 weeks, then strain
Salve: Infuse oil with herbs, then mix with beeswax
Poultice: Crush fresh herbs and apply directly to skin
