1

Your first remedy, within 30 minutes

A guided first recipe, made with one or two oils and what is in your kitchen. Finished tonight, used this week.

2

The science behind it, explained plainly

Two free courses, How to Blend Essential Oils and Essential Oil Foundations & Smarter Blending, teach safety, dilution, and what each plant does.

3

Your whole path, mapped

Your dashboard shows your first courses today and the road to Specialist, Certification, and Clinical when you are ready.

From Natural Living · your first week

Calm Evening Roller

10 ml roller bottle · 2% dilution · ready in five minutes

  • Lavender (Lavandula angustifolia) 2 drops
  • Sweet Orange (Citrus sinensis) 2 drops
  • Jojoba carrier fill to 10 ml

Make it: add the drops, fill with jojoba, cap and roll between your palms. Use it: wrists and back of the neck, twenty minutes before winding down. Patch-test first. You'll learn why in Lesson 2.

Every oil we teach with is GC/MS-tested. You'll learn to read the report
Plant-based medicine, shown not told

This is what "scientifically backed" looks like.

Every recipe in the program comes with the chemistry in plain language, in Karen's margin notes. Touch an ingredient on the card to read one. You learn this way from your first Natural Living lesson.

"Lavender does the calming, and it's the linalool doing the work."

The science: Lavandula angustifolia is rich in linalool and linalyl acetate, the constituents most studied for relaxation. You'll meet both in the chemistry unit.

"Sweet orange keeps it bright, and it's one citrus that plays nice with skin in the sun."

The science: expressed sweet orange is regarded as non-phototoxic. The course teaches you to tell look-alike oils apart.

"4 drops in 10 ml = 2%. The math becomes second nature, I promise."

The science: dilution is the heart of safe practice, strong enough to work, mild enough for daily use. Lesson 2 makes the percentages automatic.

Hover or tap the ingredients. Karen annotates every recipe in the coursework this way.
