Decoctions and Syrups

Pure Herbal Wisdom — Herbalism 101, Lesson 12

Twenty to forty minutes of active simmering isn't overcooking a tea — for tough root and bark material, it's often the only way to actually get to what's inside.

A decoction is a simmer, not a steep: plant material — usually roots, bark, or seeds — added to water and actively simmered, typically 20–40 minutes, then strained. Where infusion uses brief, gentle heat for delicate leaf and flower material, decoction uses sustained heat because tougher plant structures need more energy and time to release their compounds.

A syrup usually starts as a strong decoction or infusion, with a sweetener — honey or sugar, in significant proportion — dissolved in. It's more palatable, especially for strong or bitter herbs, and it's a format that shows up constantly in Module 6 (elderberry syrup is one of the best-known examples). The sweetener isn't just for taste: at sufficient concentration, it genuinely helps preserve the preparation by limiting the water available for microbial growth. That's real food science, not folk tradition — but it's not unlimited either; syrups still have real shelf-life limits, covered fully in Lesson 17.
