Is Hyssop Essential Oil Too Dangerous to Use? A Deeper Look with Elizabeth Ashley

Hyssop essential oil has long been surrounded by warnings and caution. But does that mean it should be avoided altogether? In this episode of A Fellowship in Essential Oils, I share why Hyssop remains one of my favourite plant allies—despite its complex reputation.

What Is Hyssop Essential Oil Used For?

Hyssop (Hyssopus officinalis) is a potent essential oil with powerful antiviral, expectorant, and cicatrising properties. Traditionally used for respiratory conditions, it has also been revered in spiritual contexts for its role in purification rituals and energetic cleansing.

In this video, Adam Barralet and I explore:

• How I use Hyssop essential oil for coughs, colds, and scar tissue

• The spiritual benefits of Hyssop, particularly in cleansing rituals

• Whether Hyssop is helpful—or potentially disruptive—for psychic protection

• The safety concerns around Hyssop oil’s neurotoxic constituents, and how to work with it respectfully

Is Hyssop Essential Oil Safe?

This is one of the most common questions I’m asked as a clinical aromatherapist. Hyssop is often flagged for its ketone content, which can be neurotoxic in large doses or unsafe for certain individuals. However, like many strong oils, it's about how you use it—not whether you should.

"Some oils demand reverence, not avoidance."

In the video, we explore the nuances of safety, and why this oil may still have a place in a well-informed aromatherapist’s toolkit.

Energetic & Spiritual Uses of Hyssop Oil

Hyssop has long been associated with purification, exorcism, and spiritual clarity. Biblically and magically, it is invoked for cleansing the soul, clearing negative energy, and resetting boundaries after trauma or emotional overload.

I’ve found Hyssop particularly helpful in:

• Rituals for energetic release

• Practices involving shadow work

• Cleansing after emotionally heavy client sessions

But as we discuss in the episode, its energy can be intense. Psychic protection with Hyssop may work for some—and feel too sharp or disorienting for others.
