What is the maximum topical dilution for Cardamom?

The adult topical ceiling is 3%, which is 6 drops per 10 ml of carrier oil and 18 drops per 30 ml at 1 ml ≈ 20 drops. For facial use or long-term daily use, drop to 0.5% — 1 drop per 10 ml.

Who should avoid Cardamom?

This site marks no avoid row for this oil, but pregnancy, children and household pets should still follow the applicable row in the matrix below, and a four-step patch test should be completed before first use.

How do I run a skin patch test?

Dilute 1 drop in 5 ml of carrier oil (1%). Apply 2 drops to the inner forearm. Cover for 24 hours. Read at 24 and 48 hours. A cool tingling is the cineole at 32%; burning is not, and means washing it off. A positive is redness, itching, burning or blistering; any of those means stop using it.

Cardamom (Elettaria cardamomum)

Q: What is the shelf life of Cardamom and how does it oxidise?

36 months. Two thirds of this oil is cineole and terpinyl acetate, both oxidation-resistant, so cardamom keeps well; the terpinyl acetate hydrolyses slowly into terpineol over years. Three years in a sealed amber bottle. The smell of an ageing bottle goes from bright eucalyptus-cardamom toward a flatter, more soapy note.

By The Aroma Desk

Cardamom oil is roughly a third 1,8-cineole and a third terpinyl acetate, which makes it a warm spice with a cool top note — and it puts it functionally next to eucalyptus rather than next to ginger. Adult ceiling 3%, a caution row for epilepsy because of the cineole fraction, and a genuine rotation problem if you also use rosemary or eucalyptus.

04 · Rotation

Rotation & substitution

Cardamom is cineole-forward at 32%, which puts it in the same functional slot as eucalyptus and rosemary CT cineole. Do not stack them in one blend, and rotate cardamom out every few weeks with a non-cineole warm note such as ginger or black pepper.
