The basics

How to use Calamus (Sweet Flag)

These are the everyday application instructions for Calamus (Sweet Flag) — covered once here so each use case below can focus on what's specific to that purpose.

Diffuse
Add 3–8 drops to a diffuser with water. Run for 30–60 minutes at a time in a ventilated room. The most foundational way to take in an essential oil.
Topical
Always dilute first in a carrier oil (jojoba, sweet almond, coconut). A 2% dilution is about 12 drops per ounce of carrier. For face or sensitive skin, cut to 0.5–1%. Patch test on the inner arm before regular use.
Inhale direct
Open the bottle and take 3 slow breaths — the fastest way to get the effect when you need it now. Or dab 1 drop on a tissue and tuck inside a pocket or pillowcase.
Bath
Mix 5–10 drops with a tablespoon of carrier oil or unscented bath salts (oil doesn't mix with water — the carrier prevents skin irritation), then add to a warm tub.
