Therapeutic Blending — Synergy and Carrier Selection

From single-oil use to deliberate blending — the chemistry, the synergy, and the safety

Twelve lessons that move you from using single essential oils to building deliberate therapeutic blends. You will learn the chemistry families that organize the field, what synergy means in practice, how to choose carrier oils for specific therapeutic purposes, the dilution math for each application route, and how to formulate blends for the most common clinical patterns — stress, inflammation, respiratory, and skin work.

Taught by Deidre Starner, Master Herbalist

What you'll learn

  • Place any essential oil into its dominant chemistry family and predict its general action profile from chemistry
  • Build a 3-5 oil therapeutic blend with a documented synergy rationale rather than a recipe
  • Choose carrier oils based on therapeutic intent, not just availability
  • Calculate accurate dilution percentages for any application route, including pediatric and elder adjustments
  • Apply safety filters (phototoxicity, sensitization, pregnancy, drug-interaction) to any proposed blend before recommending it
